Re: "script cast member not found" -- bug?

[Irv Kalb]

I've seen it many times.  I've never been able to reproduce it 
exactly, but I usually see it when I am debugging through a parent 
script.  I believe that what happens is that Director "looses track" 
of the compiled code for a script.  It thinks that the script has 
been compiled, but it can't find it.

My general fix is this:
Open the script
Select the whole script
Open a new script window
Paste
Give the new script, the old script name
Delete the original script
Save and compact

Select the new script in the cast
Cut it from where it is
Paste it back into the original slot in the cast

Recompile all scripts
Save and compact
By deleting the old script and creating a new one, it forces Director 
to think that this is a new script and therefore, compile new code 
using it.

Hi list...
Anyone ever experience a "script cast member not found" error, when it's
really there?
My movie has a linked cast named "functionality," which contains all my
scripts.  It also has a movie script with a prepareMovie handler that
instances a parent script called "the tools."
Suddenly, when it gets to this line in the prepareMovie handler...
gTools = script("the tools", "functionality").new()
It gets one line into the new() handler of the parent, and then errors
"script cast member not found."
How does this happen?  Debugging steps into that script, meaning it was
found, but then it can't find it?

Re: Collating multiple returns from sendAllSprites

[Irv Kalb]

You can use a list (untested, but the idea is right):
someList = []
sendallsprites(#GetCheckboxValues, "myCheckboxGroupID", someList)
nItems = count(someList)
and in the sprites:
on GetCheckboxValues me, groupID, aList
if groupID = pThisGroupID and someglobal then
append(aList, spriteNum)
end if
end
The list is passed "by reference" so that the same list will be sent 
to all the sprites, and each will add it's own sprite number to the 
list in succession.

Hi list
A minor conundrum is at hand. I'm building a simple form and one question
consists of a number of checkboxes, each one with its own unique numeric
value. They are checkboxes because the user can select any number of them.
When the form is submitted I want to total up the values returned by those
checkboxes. I was originally going to use sendAllSprites to send a message
to all checkboxes within a specified group, who would in turn report back
their numeric value if they were checked.
The problem is though is that the return value for, say, checkbox #2 will
overwrite the value of checkbox #1 before i can collate all results to total
them up, and given my post-injury fatigue my brain has gone dead on how to
get around it lol.
Rough pseudocode of what I was going to do:
-- calling routine
result = sendAllSprites(#GetCheckboxValues, "myCheckboxGroupID")
-- inside the checkbox behaviour
property pThisGroupID -- unique ID for this checkbox group
property pSelected -- boolean for checked state
property pMyValue -- value of this checkbox
on GetCheckboxValues me, groupID
if groupID = pThisGroupID and pSelected then return pMyValue
end
So as you can see, the variable "result" will be overwritten with each
message in response to sendAllSprites.
Any ideas?

Re: AW: OOP: shortest handler name

[Irv Kalb]

If you are using it this way, three things:
1) Your routine "t" doesn't (and shouldn't need to be) a method of a 
parent script.  Instead, it should just be a globally available movie 
level handler.

2)  Please don't use member numbers.  Yes it's shorter (fewer number 
of characters), but as soon as you or someone else decides to move a 
member within the cast, your program breaks without any warning.  Use 
member names instead.  As an added benefit, it will wind up making 
your code easier to read.

3)  if you are just stringing together the text of a bunch of 
members, you could pass in a list of members to concatentate:

on t listOfMembers
  nMembers = count(listOfMembers)
  output = ""
  repeat with i = 1 to nMembers
thisMember = listOfMembers[i]
output = output & member(thisMember, "websiteBuilder").text
-- or faster:
-- put the text of member thisMember of castlib "WebBuilder" 
after output
  end repeat
  return output
end

And call it like this:
htmlText = t([3, 2, 7])
or preferably (see #2 above):
htmlText = t(["header", "body", "trailer"])
Irv
PS:
  on t chunkNumber
  return member(t, "websiteBuilder").text
end
I think you meant:
  return member(chunkNumber, "websiteBuilder").text

You are right and that is what I normally do. But in this case I need the
name of the handler to be short, because the purpose of the handler is to
get me the content of a text cast member. The whole program is for bulding a
web site. The various segments of the HTML code are stored in text cast
members. And I need the short handler as abbreviation when concatenating the
different html chunks. So in this case, the short handler name makes the
code even easier to read!
Instead of coding
htmlText = member(3, "websiteBuilder").text & member(2,
"websiteBuilder").text & member(7, "websiteBuilder").text
I can write htmlText = t(3) & t(2) & t(7)
with the function
on t chunkNumber
  return member(t, "websiteBuilder").text
end
Or is there a smarter way to do this?
Thanks

Re: OOP: shortest handler name

[Irv Kalb]

Inside a handler (or if you prefer, "method" of a parent script or 
behavior script), you need to have the "me" in two circumstances:

1) if you have any other parameters.  This is because methods expect 
to see the current instance of the object as the first parameter 
(this is really what "me" is), then the next thing is the real first 
parameter.  So if you had a method like this:

on mMyMethod me, param1, param2, ...
and a call like this:
someObjectReference.mMyMethod(var1, var2, ...)
The value of someObjectReference is passed into the handler and is 
given to the variable "me".  The value of  var1 is given to param1, 
v2 is given to param2, etc.  So, bottomline, if you are passing in 
any more variables, you need to have "me" to catch the object 
reference.

2) if you are going to call any other method in the same script. You 
will need "me" here if you want to call some other method since you 
need to pass the object reference along, for example:

on myMethod1 me
   ... some code
   me.myMethod2()
   ... some code
end
on myMethod2 me
  ... some code
end
Since myMethod2 is a method of a script, it must have an object 
reference just like myMethod1.  When calling myMethod2, you must use 
"me." to tell it which instance.  If you didn't have "me" in the 
definition of myMethod1, then you would get a compilation error on 
the call to myMethod2, because "me" is undefined.

Consider yourself enlightened about your baxic question.
All that being said, I always add "me" to all methods.  It's just 
easier to remember to do it all the time, rather than trying to 
figure out when it is not needed.

Also, while "x" is very short and will save typing, I would never use 
such a name.  Over time, you (or more correctly, I) would forget what 
the method does if it didn't have a descriptive name.  :)

Hi everybody,
I have a baxic question about parent scripts.
Until now, a typical handler definition in a parent script of mine looked
like
on mWhatToDo me

end
and it was run like that:
me.mWhatToDo()
Now I have a handler that is called very often so that it would be nice, if
the handler name were very short. As short as possible that is.
This could be:
on x me
...
end
which could be run with
me.x()

Next I was asking myself, if the "me" could be omitted.
I tried
on x
end
and called it with:
x()
And it worked!
However I am sure there must be something wrong with it. There must be a
reason for the "me" after all.
Can anybody enlighten me?

Re: List question

[Irv Kalb]

Matt,
I would suggest a slightly different approach.  I would probably 
reverse the property and value positions in your two lists.  That is, 
build up a sorted lists like:

list1 = [0:"", 19:""]
This way, you could walk through each list and check if the the 
property exists in the other list, something like this (tested with 
only your data):

on test
  List1 = [0: "", 10: ""]
  List2 = [10: "", 19: ""]
  mergedList = combineLists(List1, List2)
  put mergedList
end
on combineLists  list1, list2 
  numFeatures1 = count(list1)
  numFeatures2 = count(list2)

  if numFeatures1 < numFeatures2 then
smallerList = list1  -- doesn't copy, just sets a pointer
largerList = list2
numInSmallerList = numFeatures1
  else
smallerList = list2
largerList = list1
numInSmallerList = numFeatures2
  end if
  outputList = duplicate(largerList)  -- make a copy the larger list 
as a starting point
  sort(outputList)

  -- now loop through the items in the smaller list. 
  --  If an item is not in the output list, add the property and the value
  -- else there is a match on a property in the larger list, add to 
the existing value string

  repeat with i = 1 to numInSmallerList
theProp = getPropAt(smallerList, i)
theValue = smallerList[i]
where = getAProp(outputList, theProp)
if voidp(where) then  -- not found 
  addProp(outputList, theProp, theValue)
 
else  -- found a match
  theExistingValue = getAProp(outputList, theProp)
  theExpandedValue = theExistingValue & theValue
  setProp(outputList, theProp, theExpandedValue)
end if
  end repeat
  return(outputList)
end

This gives you a merged list with the properties and values reversed:
-- [0: "", 10: "", 19: ""]
Hope this helps,
Irv
PS:  You have to be careful about quote marks within your strings, e.g.,
"text align="right">"
is not a valid Lingo string  (I faked it for this test)

Hi Irv,
You know, of course, that there's a simple work-around. Before an 
object deletes itself from the actorList it gets its position and 
compares it with the total number of entries. If it isn't the last, 
it makes a call to the stepFrame handler of the next object and it 
removes itself. Something like:
--
on mKill( me )
  pos = (the actorList).getPos( me )
  if ( pos < count(the actorList) ) then
call(#stepFrame, [(the actorList)[pos + 1]])
  end if
  (the actorList).deleteOne( me )
  -- remove remaining references ...
end

RE: Help yourself, children

[Irv Kalb]

Peter,
Because of the problem with the actorList, many years ago, I wrote a 
replacement for the actorList which would solve the deletion problem. 
It's a manager which I called the FrameMgr.  The basic idea is that 
it is instantiated at the beginning of your movie, and it inserts 
itself into the actorList.  Anything that wants to be in get frame 
event notification, registers itself with the FrameMgr (using the 
mAdd) call.  When you register an object, it starts receiving 
mFrameEvent calls instead of stepFrame events.  You can delete any 
object by caling its mDelete method.  It does the right thing and 
ensures that objects are deleted correctly.  When you are ready to 
stop your program, call the FrameMgr's mCleanup method, and set the 
object reference of the FrameMgr to VOID.

I haven't used this in a long time, but I remember that it worked. 
It even allows you to remove an object from the FrameMgr in its own 
mFrameEvent method.

Enjoy:

Hi Irv,
Thanks for making clarifications. So, with your reply in my mind, I can see
that the best way to remove childs (sorry Zav, but "children" doesn't sound
good) from actorList is only through explicit statements, right? But then, I
would definitely argue that it is not dynamic. It's hardcore typing. I'm not
criticizing you post though, I'm just exploring the best way to deal with
objects.
Thanks

Re: Help yourself, children

[Irv Kalb]

Before I answer your question, I'll pose a question to you.  Why 
would you do this??  (Unless you are just trying to learn about the 
actorlist.)

Instead, if you are trying to move a sprite, it would be much easier 
to do the same thing with a behavior attached to the sprite in 
channel 1.  Instead of parent scripts dealing with the actorList, 
behaviors automatically get exitFrame calls every frame.  Therefore, 
you could do what you want using this behavior (untested):

property spriteNum  -- automatically given the correct number
property pSprite
property pIncrement
on beginSprite me
  pSprite = sprite(spriteNum)  -- get a reference to the sprite itself
  pIncrement = 1
end
on exitFrame(me)
  if pSprite.locH < 500 then
  pSprite.locH = pSprite.locH + pIncrement
  end if
end
As for an object deleting itself from the actorList ... here's the 
problem.When Director goes to a new frame, it basically goes 
through it's equivalent of a repeat loop from 1 to the number of 
items in the repeat loop, calling the stepFrame handler in each

efficient way to make the object remove itself from the actorList? Let's say
in the "Move" script we have the following condition and an action applied:

  pLocH = pLocH + pIncrement
  if(pLocH > 500) then
_movie.actorList.deleteOne(me)

Is that a good way to make the object remove itself from the actorList? I
have tried many other techniques but they don't work.

Re: GPDL again

[Irv Kalb]

I'm a little familiar with that write-up, maybe I can help.  While 
you can have code in a GPDL, you generally put code in there that 
will help you build up lists, or provide selections for the resulting 
Parameter Dialog Box.

The basic thing that is going wrong in your script is that GPDL does 
not run at run-time, it runs at author time.  Therefore, the variable 
"currentSpriteNum" doesn't have a value.

I put a breakpoint after the first line of code in your GPDL and 
found that currentSpriteNum had a value of zero.  Then stepping 
through the code, it is trying to get the locH and locV of sprite 0. 
Since sprite 0 is not a real sprite, the locH and locV should not be 
trusted.  Like you, I found (after converting 
_player.currentSpriteNum to the currentSpriteNum so I could do this 
in DMX), that there must be a difference in dot syntax versus verbose 
syntax which gives you the error.

However, this is all unimportant.  The real problem with your code is 
that GPDL runs at author-time rather than a run-time.  And at 
author-time, there are no Director sprites.  The simple solution is 
code that refers to sprites and sprite locations should be moved into 
the on beginSprite handler.  on beginSprite runs right after Director 
"instantiates" each sprite.

Further, "currentSpriteNum" is not needed here.  I suggest declaring 
and using "spriteNum" instead.  It is automatically given the correct 
value at runtime.  From the Lingo Dictionary:

This property was more useful during transitions from older movies to 
Director6, when behaviors were introduced.  It allowed some 
behavior-like functionality without having to completely rewrite 
Lingo code.  It is not necessary when authoring with behaviors and is 
therefore less useful in the past.

Bottom line:
property spriteNum
property pSprite
property pStartH, pStartV
on getPropertyDescriptionList  -- no "me" needed here
-- do whatever you want to create a property list to be returned to 
define the dialog box
end

on beginSprite me
  pSprite = sprite(spriteNum)
  pStartH = pSprite.locH
  pStartV = pSprite.locV
end

A short background. When you search the internet for Director/Lingo

article you'll discover that this handler can be used not only for popping
up the parameters window but also to include some code in it. I tried it out

Re: Need HideHotSpots and ShowHotSpots capability

Welcome to the list!
I remember going through the exact thing about a year ago.  I was 
looking for a programmatic way to do the exact same thing.  I also 
had the requirement that I had to be able to do VR HotSpots 
cross-platform.  Unfortunately I could not find a solution.  I also 
ran across the Developware version, but it was Windows only.  My 
client eventually dropped the requirement to show/hide ths hotspots.

I never followed through with trying out the Developware Xtra as I 
needed a cross-platform solution, so I can't tell you how well it 
works.  But if your kiosks are Windows only, I think that they are 
the only game in town.

would like to be able to write some Lingo code to make the QTVRs 
reset to the "Hotspots not Visible" mode, so when a potential

I am using Director 8 and I have the reference books:  "Director in

cannot find the correct property name for HotSpots.

I have been able to find the VRHotSpotEnter and VRHotSpotExit 
properties, which will give Boolean values that can be acted upon, 
but I can't find the property name for setting Visible/Invisible.

It occurs to me that this may be a property of the controller, but I 
have been unable to find settings there either.

Any assistance will be most appreciated.
I downloaded the demo version of an Xtra from Germany, which 
purports to offer the Hide/Show capablity I need, but the

Re: pass with prepareMovie not possible?

[Irv Kalb]

It's really not clear what you are trying to accomplish, but here is 
an approach that I have used in projects with multiple movies, maybe 
you can use something similar.

Each movie links to one common external castlib, lets call it 
GCode.cst (for global code castlib).  In this castlib, I have a movie 
script with a handler called SharedPrepareMovie and another called 
SharedStartMovie.  Each of these two handlers take a parameter of a 
symbol.  Back to this in a second.

Then each movie has its own movie script cast member which has the 
real on PrepareMovie and on StartMovie handlers.  In these handlers, 
I do any custom code that may need to be done for this particular 
movie, then I call the Shared version of the handler and pass in a 
symbol for the type of the movie that it is.  For example, in some 
large projects I may have a mainmenu module and some chapter movies, 
and a help movie, etc.  So a typical chapter movie might look like 
this:

on prepareMovie
  -- any special code for this movie, if there is any
  SharedPrepareMovie(#chapter)
end
on startMovie
  -- any special code for this movie, if there is any
   SharedStartMovie(#chapter)
end
Back to the shared handlers, the movie script in the GCode castlib is 
really just a case statement:

on SharedPrepareMovie symMovieType
   case symMovieType of
  #chapter:   -- whatever you need to do all chapters
  #menu:  -- whatever you might need to do for a menu
 #help:  -- whatever you might need to do for a help movie
 -- etc.
  end
end
And I have a similar approach for the SharedStartMovie handler.
Hope this approach helps,

I have the following problem:

each of these procedures should enable that behaviour.
But now I have the problem that only the first prepareMovie is 
executed and the pass does not seem to have any effect at all.
Neither the scripts in the internal cast nor those in the external 
ones execute their prepareMovie or the startMovie messages.

RE: When and when

[Irv Kalb]

Peter,
You should not be worried about the amount of memory used by local 
variables.  All local variables are allocated using a stack 
mechanism.  When you call a handler, space for local variables is 
allocated on the top of a stack (actually, it might be done when 
Lingo first encounters each local variable, but that's not really 
important).  When your code returns from a handler, the space 
allocated for all the local variables used in the handler is "pop'ed" 
off the stack and given back to the system.   You don't have to do 
anything, Director handles this for you.

Re: database lingo vs. xtra

And if you want your Lingo-based "database" to run faster, check out 
an article I wrote for DOUG many years ago at:

http://www.director-online.com/buildArticle.php?id=442
This describes a technique I use to store data in cast members as 
Lingo routines.  I don't know if the timing is still accurate, but 
when I testing this approach against storing data as just text or 
field members, my approach was about seven times as fast.

For the last 4 years I have had a "database" running using external

I have 5 external casts (Apprentices, Employers, Coordinators,

Re: When and when

[Irv Kalb]

Congratualtions on your thesis!
In just looking over the versions of getPropertyDescriptionList from 
your post, both have errors. GPDL #1 says that you are trying to 
build a list of members, but what you are really displaying is a list 
of numbers.  This is because you are just adding the value of the 
variable "j" to the list.  "j" is really just an integer.  Further, 
while you are iterating over the number of members of castlib 
"Assets", you are not checking the correct member in the if 
statement.  Finally, for speed, you should always use a local 
variable when you have a repeat loop going up to some value which is 
returned from a function.  In your case, 'the number of members of 
castlib "Assets"' will not change during the loop, so you should do 
the check once.  The code should look more like this (untested):

property pVectorShape
on getPropertyDescriptionList(me)
  vectorShapesList = []
nMembers = the number of members of castlib "Assets"  -- do this once here
repeat with j = 1 to the nMembers
  if(member(j, "Assets").type = #vectorShape) then
vectorShapesList.add(member(j, "Assets"))
  end if
end repeat
  descriptionList = [:]
  descriptionList.addProp(#pVectorShape, [#comment:"Which one",
#format:#member, #range:vectorShapesList, #default:1])
  return(descriptionList)
end
GPDL #2 has two errors.  First, in your repeat loop you are trying to 
access member(j, i), but "i" has no value.  Then, you are trying to 
add to the vectiorShapesList a variable called "theName" but that is 
not defined either.

However, I believe that your general question is really about when 
you should use a variable to store  results of a function.  You 
should always use one if you are going to re-use the value multiple 
times and the value doesn't change (as in the description above). 
However, the other case that you describe has to do with using a 
local variable versus just using the results of a function directly. 
The answer is that it really is up to you.  It really is a matter of 
style.  Here's an example:

on someHandler
  someVariable = function1(someParam) + function2(someOtherParam) + 
someOtherVariable
end

versus:
on someHandler
  f1Result = function1(SomeParam)
  f2Result = function2(SomeOtherParam)
  someVariable = f1Result + f2Result + someOtherVariable
end
You will get the same answer whether you do, or do not use a local 
variable.  The main reasons to use local variable(s) are for clarity 
and debugging.  I personally like to use local variables for 
intermediate results for debugging purposes.  If you store some 
intermediate result into a local variable, you can set a breakpoint 
right after a call to a function and ensure that the function is 
returning the value you expected.   It really helps track errors down 
quickly.  Further, by splitting things up into multiple lines like 
this, I often find it easier to read.

Others disagree with me and try to pack as much into a single line as possible.
Using local variables will be slightly more expensive time-wise, but 
unless the function calls are made millions of times, you will never 
notice a slowdown by using an additional local variable.

Where does the Tone sound start playing?  In the code that you show, 
you are only capturing the pan value of the Tone sound, but not 
setting it.

I don't know if this helps, but it sounds like you probably want to 
create five lists (or a list of 5 lists).  Initialize them to the 
empty list in your beginSprite handler, and add to the appropriate 
one in your dataCollect routine.

Maybe you need to show us more of what you are really doing.

 I want to store the apparent direction of the warbling tone (as a

the appropriate list or  file; that is, if the white noise comes from the far
left, I want to store the direction of the warbling sound in the list for the
far left white noise.  But since I have the warbling tone in an exitFrame
handler, it outputs each of the five lists.

If I remove the warbling tone from the exitFrame handler and put it in the
mouseDown handler, the warbling  doesn't occur at all.
I don't know if any of this will make sense but here goes. Here's the basic
code (I've edited out non-essential stuff):
on mouseDown me
  sound(1).play(member("white noise"))
  pHissDirection =   sound(1).pan
end
on exitFrame me
  ptoneDirection = sound(2).pan
  if the doubleclick then
dataCollect 
  end if
end

dataCollect is where the lists are.

Re: movie vs behavior lingo

[Irv Kalb]

Handlers in movie scripts are available globally.   So, if you have 
an on mouseUp handler if a movie script, and nothing else is 
"catching" the mouseUp events, then they get sent to the on mouseUp 
handler in the movie script.

If/when you have an on mouseUp handler in a behavior, it only applies 
to the sprite or sprites to which you have that behavior attached. 
For example, if you have a sprite in channel 1, and you attach such a 
behavior, then if you do a mouse up while over that sprite, then 
Director will send the mouseUp event to that behavior.

If you just have this code in a behavior script and don't attach the 
behavior to a sprite, then the code will have no effect since it is 
not really active at all.  Specifically, there will not be any 
"instances" of this script running.

Hope this helps,
Irv

Re: Lingo Animation Optimization Test

[Irv Kalb]

Hi Anthony,

In looking this over quickly, I found one optimization, one warning, 
and one nigley:

Optimization: In your "on Animation" you have a line that says:

  if pnCurrentMem > plMembers.count then

This will call the count routine EVERY time.  Instead, create a new 
property, e.g., pnMembers, set it in your "on PlayAnimation" method 
when you get a new list of animation members, and use it in the test 
above.

Warning: In the "on PlayAnimation" routine, you have a line:

  plMembers = lMembers

Lists are passed by reference.  Therefore, if the routine that starts 
the animation by calling this routine changes its version of this 
list, even after it returns from this call, the list in your behavior 
will be changed.  This potential problem can be avoided (unless it's 
done on purpose this way), by changing the above line to:

  plMembers = duplicate(lMembers)

Nigley:  In your stopAnimation routine, you have a parameter variable 
called bResetMem.  But you since you are comparing it to symbols 
(#original and #first) it should really be called yResetMem according 
to your naming convention.

Other than that it looks clean.

Re: Lingo and PHP

[Irv Kalb]

Two more things in addition to what's already been said.

About getting data back from PHP ... PHP is typically used on a 
server to create a custom web page on the fly and returns a string 
which is an html page.  However, you can use PHP to create and return 
any string.  That string can be the result of a database search.  The 
string is returned in netTextResult.

If you are looking for a standardized way to make netLingo calls, 
check out my on line book at:

Re: Error With Behavior in Linked Cast?

[Irv Kalb]

It could be one of these weird cases where Director loses track of 
the compiled version of the member.  If you still have your copy in 
an internal cast, delete the script member from your external cast, 
save and compact, then copy and paste it again.

Or perhaps there are no field members in the cast.

Then there are three other problems (or maybe your mail client 
doesn't support the use of colons).

1)  GetPropertyDescriptionList defines a property list.  Your first 
line should be:

 property = [:]

2)  Your add prop command is missing colons also, should be

propertyList.addProp (#pmAnimation, [#comment :c, #format: f, #default: d])

3)  plAnimation is not declared as a property, so your beginSprite 
just assigns a value to a temporary variable and then the variable 
goes away.

Re: Quick Time Dynamic Play

[Irv Kalb]

It's not clear from your posting if your difficulty is in the "if" 
syntax or in the ability to play a QT movie.  First, here's the if 
syntax.  This code assumes that the variable "pcgreaterthan4" has to 
be LESS than each threshhold.  If you want it to be less than or 
equal, just add an equal sign after the less than sign:

property spriteNum

on mouseUp me
  if pcgreaterthan4 < 0.35 then
playMovie("someMovieName")
  else if pcgreaterthan4 < 0.5 then
playMovie("someOtherMovieName")
  else if pcgreaterthan4 < 0.85 then
playMovie("yetSomeOtherMovieName")
  else  -- pcgreaterthan4 is >=  0.85
playMovie("someCatchAllMovie")
  end if
end
Then in order to play a QT movie, you need to add an "on playMovie" handler.

on playMovie me, aMovieName
  sendSprite((spriteNum + 1), #mSetMovieNameAndPlay, theMovieName)
end
The code here depends a lot on your user interface.  For this code to 
work, I'll assume that you have a quicktime sprite in the next 
channel up.  You should have that quicktime member set to link to 
some "dummy" movie.

Finally, on the QuickTimeSprite, attach a behavior that says 
something like this:

property spriteNum
property pSavedMoviePath
on beginSprite me
  pSavedMoviePath = sprite(spriteNum).fileName
end
on endSprite me
  sprite(spriteNum).fileName = pSavedpath
end
on mSetMovieNameAndPlay me, theMovieName
  sprite(spriteNum).fileName = the moviePath & theMovieName
  sprite(spriteNum).movieRate = 1  -- start it playing
end
Hope this helps.

Re: Setting properties via a method's parameters

[Irv Kalb]

I just tried it, and I found that version #2 does not compile.  I get 
a "comma expected" within the pCurrent.pModule part of the on 
mHandler line.

If I think back real hard to my days of writing compilers, I can 
understand why this would be.   Parameters  that are declared on a 
handler line are allocated storage just like temporary variables 
within a handler - on the system "stack".  This way when you leave a 
handler, all temporary variables and variables implicitly declared in 
the handler definition can just go away.  For example, consider the 
following:

on mHandler me, paramVar1, paramVar2
  temp1 = paramVar1 + 1
  temp2 = paramVar2 + 1
  ...
end
In this code, when execution enters the handler mHandler, storage for 
paramVar1, paramVar2, temp1, and temp2 are all allocated on the 
stack.  When the handler exits, Lingo just "pops" these four 
variables off the top off the stack and these variables go away.

Properties of the object are stored in a different place.  In fact, 
they are stored at the address returned in the "return me" line.  The 
object reference itself points to where the property variables are 
stored.

Therefore, you could not put a property variable in the line that 
defines a handler.  Property variables and temporary variables are 
stored in different places.

Hope that made sense ... and I hope it is right  :)

Re: Accessing sprite(x) properties via variable

[Irv Kalb]

Maybe I don't really get what you are trying to ask.  There are two 
different things going on here.   There are sprite properties and 
there are properties defined in one or more behaviors - and they are 
very different beasts.

Things like locH, locV, blend, etc are properties of the sprite. 
Each is accessable by directly accessing them:

  sprite(x).locV
  sprite(x).locH
  sprite(x).blend
Since these things are "known", you can get them directly.  (Maybe I 
don't really get what you are asking here)

However, if you want to get a property of a behavior attached to a 
sprite here's how to do that.  I just tried some code like this in a 
behavior and it worked:

property spriteNum
property p1
property p2
on beginSprite me
  p1 = 8
  p2 = 9
end
on mSetValue me, symPropName, newValue
  setProp(me, symPropName, newValue)
end
on mGetValue me, symPropName
  theValue = getProp(me, symPropName)
  return theValue
end
and attached it to sprite 1

then I did this from the message window:
put sendSprite(1, #mGetValue, #p1)
--8
sendsprite(1, #mSetValue, #p1, 14)
put sendSprite(1, #mGetValue, #p1)
-- 14
Is this what you are looking for??

By the way.  I understand what you mean, but the term "OOP Nazi" is 
extremely offensive.

Re: Accessing sprite(x) properties via variable

[Irv Kalb]

Are you looking to do  this for many, many different properties?

If not, a "standard" way is to get and set property values is using 
accessor methods.  In a behavior attached to the Mass-Spring-Damper 
thing:

property pMyProperty

on mGetMyProperty me
  return pMyProperty
end
on mSetMyProperty me, newValue
  pMyProperty = newValue
end
Then do the set or get via a sendSprite:

  someVariable = sendSprite(channelOfDamper, #mGetMyProperty)

or

  sendSprite(channelOfDamper, #mSetMyProperty, newValue)

You would need one such pair for each property.  However, if you have 
a number of different properties, then you could also pass in the 
property name to get/set as an argument:

on mSetMyProperty me, symProperty, newValue
  -- I think this will work
  me.symProperty = newValue
  -- If not, you can use a case statment for each of the properties 
in your script
  case symProperty of
#pPropertyName1:
   pPropertyName1 = newValue
#propertyName2:
   pPropertyName2 = newValue
etc.
end

on mGetMyProperty me, symProperty
  return me.symProperty
  -- Or use a case as above
end


If there are multiple properties you need to set/get at once, you 
could package them up into a list.

references was the logical option.

And one more thing: why did you correct your post to sendSprite,
#bumpCounterH, 2)? The previous post was just fine.
In my original posting, I wrote:

  sendSprite(1, #bumpCounterH, xref, 2)

after I sent it, I realized that the "xref" was left over from your 
original code.  So I changed it in order to show that the "xref" 
should be removed:

  sendSprite(1, #bumpCounterH, 2)

which was the right way of doing it.

Glad it helped!

Re: scriptInstaceList

[Irv Kalb]

Short answer:  for a case like this, use the sendSprite command instead, e.g.,

  sendSprite(1, #bumpCounterH, xref, 2)

SendSprite will send the message to all instances of all behaviors 
attached to the sprite.  Assuming that there are no other behaviors 
attached that have a bumpCounterH routine, this should work fine.

As you figured out, the "call" approach will work correctly if you 
have the proper object reference to the proper script instance.  An 
ideal way to use "call" is when objects (and/or behaviors) have a way 
of "registering" themselves to the thing that will wind up calling 
them back.

Lets say that two different behaviors want to be called back when 
someone clicks on yet a third behavior.  Each of the two behaviors 
could send a mRegister message passing "me".  me will always refer to 
the current instance of the current script.  On the receiving side, 
the script with the mRegister, simply adds the parameter to a list of 
objects/behaviors that want to be called back:

  property pListOfBehaviorsThatWantToBeCalledWhenIAmClickedOn

on beginSprite me

on new me
  pListOfBehaviorsThatWantToBeCalledWhenIAmClickedOn = []  -- start off empty
end
-- Build up a list of objects/behaviors that want to be called back
on mRegister me, instanceThatWantsNotification
  append(pListOfBehaviorsThatWantToBeCalledWhenIAmClickedOn, 
instanceThatWnatsNotification)
end

-- Our action has happened, lets call back everyone who registered
on mouseDown me
  call(#someCallbackRoutine, 
pListOfBehaviorsThatWantToBeCalledWhenIAmClickedOn, etc.)
end

I hope that makes sense.

Call will be faster because it targets only the instances you really 
want.  But as you found out, it is much more difficult to get to 
those references.  Bottom line, use sendSprite and it should work 
just fine.

Also.  "getAt" is a very old form.  Newer Lingo allows you to get at 
elements of a list through bracket syntax:

  getAt(myList, itemNumberX)

is the same as the newer and cleaner:

  myList[itemNumberX]

So, there is no need to use getAt any more.

Hello everyone,

I've got a sprite with 2 behaviors attached to it: 1 - "horizontal movement"
(it has the bumpCounterH handler with three args), 2 - "vertical movement"
(it has the bumCounterV handler with three args too). I use the call command
to send a message to the first handler along with some parameters. What the
Director MX documentation says is (p.370):
on mouseDown(me)
  xref = getAt(sprite(1).scriptInstanceList, 1)
  call(#bumpCounterH, xref, 2)
end
This works fine, it calls the specified handler and passes the defined
argument. But should the call command be used only with getAt list command?
What if I want to reference the behavior via its name?
e.g.

on mouseDown(me)
  call(#bumpCounterH, sprite(1).scriptInstanceList, "horizontal movement",
2)
end
Or what if I want to use this command directly?

e.g.

on mouseDown(me)
  call(#bumpCounterH, sprite(1).scriptInstanceList, 1, 2)
end
I tried this, it "works". I mean the right behavior is being called but the
name of the behavior comes as the first parameter, and the first parameter
in the call shows up as a second parameter in the handler being called and
so on. So this kind of shift is going on.
So does scriptInstanceList work only with getAt command or with set
variables?

Re: Re: updating an online database

[Irv Kalb]

Lee,

From your description below, it sounds like you are using the 
NetManager correctly.  Therefore, I'm guessing that the problem, 
whatever it is, in on your server side with your asp page.  The error 
code that is reported is simply the value that is returned when the 
NetManager calls NetError.

If you want to verify this, put a breakpoint in the NetManager right 
after the call to netError and see what is being returned.  Is your 
asp page set up to return any text?  I don't know anything about asp, 
but perhaps you have intended the page to return a text value of 1, 
but it is returning as an error code of 1 instead.

In the case where you are using the netManager to pass in your list, 
does the data in the database get updated correctly - even though it 
returns an error code?

Re: updating an online database

[Irv Kalb]

I don't know if the problem is in your net routines or at the server, 
but I have have a different approach to net routines.  I have a whole 
chapter in my on line book on building a net manager that would 
handle many net calls.  Check it out at:

http://www.furrypants.com/loope/

Chapter 14 goes into detail about this.  I have used this net manager 
to do exactly what you are describing - sending postNetText commands 
to a CGI script (PHP) that talks to a database (mySQL)

I would guess hat your current approach locks out user activity while 
all the messages are being sent.  My net manager allows all 
interactivity to continue while the messages and net checking are 
handled in the background.

this indeed is correct for streaming QT played in the QT player or

to clarify what is happening consider the following:

if i play the above steam in QT player i get a movie that is 256x192
if i play the same stream in director i get a movie of 160x120

any ideas why this would happen? also could anyone please test the

is this perhaps a bug in the QT implementation?

Re: sorting through lists

[Irv Kalb]

All of Alex's suggested were right on target.  I'm sure that they 
will help a great deal.

I do have one more suggestion for you.  Any time you reference into a 
sublist more than once, Lingo has to rebuild a reference to the 
sublist.  If you are going to go into a sublist multiple times, I'm 
sure it would be faster to set a temporary variable to the sublist 
and pull out values from there.  Here's a specific case.  In your 
second routine:

on filterList sList, filterStr
   rList = []
  mx = count (sList)
  repeat with k = 1 to mx 
fName = [sList[k].area, sList[k].team, sList[k].player,
sList[k].points ]
if sList[k].team =filterStr then append rList, fName
  end repeat
  return rList
end

I would bet it would be faster to do something like this:

on filterList sList, filterStr
   rList = []
  mx = count (sList)
  repeat with k = 1 to mx
subListName = sList[k]  -- store reference into a local variable here
fName = [subListName.area, subListName.team, subListName.player,
subListName.points ]
if subListName.team =filterStr then append rList, fName
  end repeat
  return rList
end
Since lists are "pass by reference", if you execute a statement like the above:

  subListName = sList[k]  -- (use whatever name is appropriate here)

you are NOT duplicating any data.  Intead, you are setting this new 
variable (subListName) basically as a "pointer" to the appropriate 
place in the original list.  This would save the time of 
dereferencing your current sList[k] five times in this routine alone.

Actually, now that I look at this code closer, there is another 
optimization you can do.  You don't even need to build up your fName 
list unless the team matches the filterStr.  So only build it 
conditionally:

on filterList sList, filterStr
   rList = []
  mx = count (sList)
  repeat with k = 1 to mx
subListName = sList[k]  -- store reference into a local variable here
if subListName.team =filterStr then
   fName = [subListName.area, subListName.team, subListName.player,
subListName.points ]
   append rList, fName
 end if
  end repeat
  return rList
end


You could probably use the same approach (using a local variable 
pointing into your list structure) in your html generation where you 
are using templist[i][j][1] twice in the same doubly nested repeat 
loop.  Set some local variable to that:

  someLocalVariable = templist[i][j][1]

then replace the current instances with the local variable.

However, I'm sure that Alex's suggestion of building the whole thing 
as a string variable, then putting it into the text of a member will 
have the most immediate impact.

Solitaire game

[Irv Kalb]

If anyone has some free time (and interest) to play around with a 
solitaire game, I've recently built a new version of an old game.

I don't play many computer games, but many years ago I got hooked on 
a solitaire game called 40 Thieves.  I played it quite a bit on my 
Mac.  But when I made the move to OSX, I didn't want to have to go 
into Classic mode to play it.  So, I wrote my own version in Director.

Anyone interested in testing it out can find it at:

http://www.furrypants.com/fortythieves/40Thieves.html

The game is very challenging and you won't win very often.  The 
instructions can be found by pressing the Help button.

Any comments, questions, problems, or suggestions please contact me offlist at:

  [EMAIL PROTECTED]

or at

  [EMAIL PROTECTED]   if you don't mind identifying yourself as a 
human (spam filter)

This game was developed entirely in Director with an extremely object 
oriented approach.

Enjoy (especially the unlimited Undo!)

Math help needed - trig

[Irv Kalb]

[Apologies in advance for a cross post.  I posted this to another 
list, but that list seems to be down right now.]

I don't want to say how many years its been since I actually studied 
and used trig and angular measurements, but suffice it to say that 
there are only fuzzy memories left.  Here's what I need to be able to 
calculate.

I have a point, and from that point I have a distance (in pixels) and 
an angle in which to travel.  I need to be able to calculate the x 
and y values (or h and v) to get to that point.

First, I want to make sure that I am using proper accepted practices. 
I was looking around at some popular math sites and found this 
diagram on math.com:

http://www.math.com/tables/art/geometry/unitcircle1.gif

In the discussion there, is says that zero degrees is defined as 
going directly to the right of the point, and the angle is measured 
in a counter-clockwise direction from there?  Is this the standard 
way of doing this type of measurement?

Assuming that is correct, then I need a formula to give me an x,y at 
a given angle.  So something like this:

on GeneratePoint  centerPoint, angle, distance
  resultPoint = -- some function of centerPoint, angle, angle and 
distance here, probably using sin or cos or tan
   -- and of course, the pythagorean theorm
  return resultPoint
end

(Multiple steps making it clearer for me to understand would be appreciated)

Too many gray cells have left the building.

Thanks,

Irv

Re: Weird error code

[Irv Kalb]

Grimm,

I ran into this problem earlier this year.  The bug is definitely in 
the vList Xtra.  I wrote Daniel Devolder (sp?) about it, and he sent 
me a newer version of his XTRA that seemed to fix the problem.  This 
was about 6 months ago (on a Mac under Mac OS).  I don't know if he 
has released a newer copy of his XTRA or not.  First thing to do 
would be to get the latest version of the VList Xtra from his site. 
If that doesn't fix it, try writing him directly.

RE: figuring out the previous handler

[Irv Kalb]

There is no built-in mechanism.  (Ancestor is not the right thing).

The easiest way to do this is to pass a different value (probably a 
symbol) from the two different  places:

on mouseUp
  SomeHandler(, #mouseUp)
  
end
on 
  SomeHandler(, #sendSprite)
 ...
end
Then in the code you posted below have a parameter that gets this 
value and branches on it:

on SomeHandler , symPreviousHandler
   case symPreviousHandler of:
   #mouseUp:
 gTools.mRecordData("set")
   #sendSprite
 gTools.mRecordData("get")
   ...
 end case
  ...

I need the handler to know the previous handler, as in:

 gTools.mRecordData("set") -- something clicked caused to go here.
else if lingoPreviousHandler = "sendSprite"
 gTools.mRecordData("get") -- something else happened, so go here.

Re: fileIO writeString()

[Irv Kalb]

Unless the Lingo documentation explicitly says differently, all Lingo 
calls are "synchronous" - which means that your program waits there 
until the operation complete.

Examples of "asynchronous" calls are the netLingo calls like 
getNetText, postNetText, etc.

Hi all...

Quick question about the fileIO xtra:

Regarding writeString(), I'm using it to write out a pretty long string.
When the Lingo gets to that line of code, does code execution stop there
until the string is entirely written out, or does it proceed to execute
the next line of code while in the process of writing to the external
file?
And by the way, is there a string length limit?

Have a stupendous day!

RE: asynchronous communication within director - synthesis

[Irv Kalb]

Well, I guess I don't have any experience with a XTRA that would do 
this.  If there is such a beast, then great.

Maybe I'm missing what the original poster was asking for.  But my 
approach would be to write a Director program that "talks" to some 
script(s) that live on a server (e.g., PHP scripts), and have the 
scripts talk to a database.  All messages would then be stored in the 
database (or just as files on a server - simulating a database) on 
the server.

The Director program could make a postNetText request to a script 
asking for all articles (riddles) that are either new, or have had a 
new message added recently.  The script would access the database and 
find all such articles and report their names back to the Director 
program.  The Director program could then display the names of all 
such articles.  The user might click on one, and the Director program 
could do another getNetText request to get the text of all articles 
in that thread.  The script could request the text from the database 
and return it to the Director program.  The Director program could 
then display it in a scrolling field.  The Director program could 
have an area where a user could add a new message to the current 
thread, or start a new thread.  This approach would not need to use 
any HTML at all.

There are many different ways to do the same thing.

Re: asynchronous communication within director - synthesis

[Irv Kalb]

If I understand what you want to do, you basically want to implement 
a message board.  In general, to do this, you have to have some sort 
of database (could be a real database, or even just a bunch of text 
files) on a server somewhere, so that a program can read the text, 
display it, and either add a message to a "thread" or start a new 
thread.

The Director On Line User Group does just this in purely PHP using a 
browser as it's interface.  http://www.director-online.com  click on

However, if you want to do this with a Director program, then you

2. Use php or perl as a go between
3. Use flash to do a xml socket connection...
4. Use a server side text file with meta data in xml format to apend

5. Embed a webpage within director using:
   a) cXtra WebBrowser
   b)WebXtra Tabuleiro
   c) html Xtra 2.0.5 Media Connect
6. Make the browser using netLingo calls (too much work)

Re: Director and Flash objects

[Irv Kalb]

I don't know how you can get the properties of the flash object, but 
getting the spriteNumber is easy.

In any behavior that is attached to the sprite (or create a new one 
if there aren't any), if you just decleare the property "spriteNum", 
it will automatically be given the number of the channel where the 
sprite is located.  For example, you could add a behavior like this:

property spriteNum

on beginSprite me
  put "My sprite number is:"  && spriteNum
end
And it will report the correct sprite number no matter what channel 
the Flash sprite (or any sprite) is in.  You can then write code to 
use the variable "spriteNum" to do whatever you want.

Re: scriptList vs. scriptInstanceList

[Irv Kalb]

The scriptlist tells you what scripts are attached to a sprite, AND 
the value of the parameters that have been set in each 
GetPropertyDescriptList dialog box.  This is available at author 
time.  The scripts are listed as:  member x of castlib y.  The 
properties are reported as a property list [#myProp1: 1, #myProp2: 
"somevalue", ...]

The scriptInstanceList is a runtime thing that tells you a list of 
what instances of behaviors scripts are attached to a script.   This 
list of behavior object references can be manipulated at run time 
(i.e., instantiate a new behavior and add it to the 
scriptInstanceList of sprite at runtime - or remove an instance of  a 
behavior at runtime).  There is no information available here about 
initial property settings.

That's just an example once the file info is loaded.

All that outputs is the artist name.

I found an example similar in Director 8.5 Studio that used apostrophes

makes a difference.
I'm just a student learning director, so any explanations would be

Re: forms and prints

[Irv Kalb]

Director does not have any built in forms.  To create forms in 
Director, you typically create the background art in some other 
graphics creation package then import the graphic into Director as a 
cast member.  Then you layer different field members on top of the 
art in different score channels so they line up with your art.

Once you have that, then you can add a print button which would 
either use the "printFrom" command (I'm not sure, but I think it will 
capture any text that has been entered into the fields), or using 
imaging Lingo to grab a portion or the whole stage and print that.

Sending the information online is much more complicated.  To do that, 
there are two basic options, sending email, or sending information to 
a server using postNetText.  If you want to send information via 
email, I would recommend the DirectEmail XTRA.  Using postNetText, 
you must write code to extract information out of each field, build 
up a property list, and send that property list to a server that is 
listening for such information.

Good luck,

Irv

Re: accessing scriptInstanceList in a MIAW: Bug...or just me?

[Irv Kalb]

Yes, this is a typical standard problem when working with MIAW's.

The ways that I use to debug MIAWs are:

1) (Quick and dirty) Use "put" statements in the code of the MIAW

and/or

2)  Build the MIAW in a way that it can be run AS a stage movie. 
That is, have checks in the MIAW code that says something like:

if the windowList = [] then
  --  debugging mode, MIAW is running as a stage movie
  --  Here, you could supply some fake data that would simulate 
coming from the stage
  --
end if

Hope this helps,

Irv

Re: Scrolling background over multiple .dcr's

[Irv Kalb]

I'm not sure if I understand the exact details of what ou are trying 
to do.  But here's the standard way to do what you want.

If you aren't already doing this, create a castlib that is shared by 
all your movies - that is, make all movies link to the same external 
castlib file.  Then move your filmstrip and (assuming that the code 
is in a behavior) the associated behavior into the shared castlib. 
Then copy the sprite 5 from your main movie and paste it into each of 
the new movies.

Re: Attach behavior to sprite...

[Irv Kalb]

... and just to clarify things even further.

beginSprite will be called by Director when the play head enters the 
spriteSpan.

If you have a behavior that you want to attach on the fly, you can 
also write a "new" handler in the script, but it will NOT be called 
automatically.  It only executes if you call the "new" handler 
specifically.

I think the ideal way to handle this is something like this:

property spriteNum

-- If behavior is added on the fly, you must call this and pass the channel
on new me me, whichChannel
  spriteNum = whichChannel
  me.CommonStartUpCode()
end
on beginSprite me
  me.CommonStartUpCode()
end
on CommonStartUpCode me
  -- here you put any code that you want to execute when starting up,
end

Quoting Evan Adelman <[EMAIL PROTECTED]>:

Evan is right, but I'd like to add something.

If you have a script already attached to a sprite (presumably attached during
authoring), if it has an "on new" handler _and_ an "on beginSprite" handler,
both will execute. New executes first, then beginSprite.
That's not contradicting Evan. He's right about the order when you attach a
behavior at runtime. When it's attached during authoring, it's different.

Re: Attach behavior to sprite...

[Irv Kalb]

Here's my guess about your problem, and a potential fix.  The problem 
has to do with the value of "spriteNum".  When you use a behavior 
normally (attached during authoring), the special property variable 
spriteNum is automatically given the corrent value.  All you have to 
do is to declare spritenum as a property, and it will be given the 
value of the channel number of the sprite.

However, if you attach a behavior "on the fly", this assignment does 
not happen.  To fix this, you can do it in your code.  I see below 
that you are creating an instance of the cursor script by doing this:

  xCursor = (script "flaCursorScript").new(2)

However, you don't show your "new" handler in the behavior.  I'll bet 
that you can fix this problem by doing this:

property spriteNum

on new me, whichChannel
  spriteNum = whichChannel  -- assign spriteNum here
  -- anything else you want to do here
  return me
end
Then just use spriteNum in  your exitFrame handler (and you don't 
need your beginSprite handler).

Or, if you like using your spriteRef variable, you can have your new 
method just do this instead:

on new me, whichChannel
  spriteRef = whichChannel
  -- anything else you want to do here
  return me
end

Re: attaching behaviors at runtime

[Irv Kalb]

Craig,

Yes, I would use a completely different approach than mucking with 
the scriptInstanceList.  If you have written your own behavior that 
handles clicking on each answer, and you have a way of talking to all 
answer sprites, then here's what I would do.

In the answer behavior, add a property called something like, 
pAvailable.  When the user can answer the question, pAvailable should 
be set to TRUE.  When the user selects one answer, you should call a 
handler in the behavior attached to all answers that sets pAvailable 
to FALSE.  The on mouseUp handler (or however you deal with mouse 
clicks) should have a simple test like this:

on mouseUp me
  if not(pAvailable) then
 return  -- user has already answered the question, just return
  end if
  --  Here you do what ever you want to with this answer
end
The behavior should start out like this:

property pAvailable

on beginSprite me
  me.mSetAvailability(TRUE)
  ...  anything else you want to do
end
on mSetAvailability me, TRUEorFALSE
   pAvailable = TRUEorFALSE
end
Then when a question is answered and you are showing feedback, you 
call mSetAvailability on all answer sprites and pass FALSE.  When you 
are ready for the next question, you call mSetAvailability on all 
answer sprites, and pass TRUE.  (If you want, the mAavailability 
could also change the color of the text for example, change it to 
gray when it is no longer available, and back to black when the new 
question is shown.)

Irv

At 6:41 PM -0400 9/10/03, Craig Taylor wrote:


Just to clarify, I have a series of "answer" buttons with rollover
behaviours.  The "on mouseUp" event calls another behaviour using a
sendSprite command.  Once the question is answered, I need to strip it of
any behaviours while the user gets an automated response to their selection.
(The "answer" sprites are still on-screen and I want no user interaction to
take place at this time.)  All sprites then reset themselves with the next
Q&A and I need to then reattach the appropriate behaviours, so the user can
answer the next question.  This all happens within the same sprite span.  Is
there a completely different way I should be attacking this, or do you think
I am on the right track??

RE: Projector vs. external cast

[Irv Kalb]

Looks like you've been getting some excellent information herre. 
Just two things to add about the line below.

If you are wanting to wind up with a protected castlib (either a .cxt 
or a .cct), then you should make a simple change to the line below. 
This line will work fine for an unprotected castlib.  If you want to 
make it work for unprotected and protected versions of the castlib, 
you can drop the extension:

  castlib("Content").filename = the moviePath & "Assets:Content"

Director will look for any file that starts with "Content" with any 
extension following it.  And as Kery said, if this is Mac only then 
you are fine.  If you want it to work on PC's and Mac's, you need to 
do something like this:

  theSeperator = the last char of the moviePath
  castlib("Content").filename = the moviePath & "Assets" & 
theSeperator & "Content"

Re: delete the last RETURN in a list

[Irv Kalb]

It sounds like you do have some confusion between a list and a 
textual representation of that list.  If you need to build up these 
items into a list (maybe for saving and using elsewhere), you can do 
it like this (untested e-mail Lingo):

fileList = []
repeat with i = 1 to the maxInteger
  thisFileName = getNthFileNameInfolder(, i)
  if thisFileName = EMPTY then
exit repeat
add(fileList, thisFileName)
  end if
end repeat
Then to display the list in a text or field member

listAsString = ''
nItems = count(fileList)
repeat with i = 1 to nItems
  thisFileName = fileList[i]
  put (thisFileName & return) after listAsString
end repeat
delete the last char of listAsString  -- eliminate final extra RETURN
member("").text = listAsString
Then you still have the list in the variable fileList.

However, if you just want to display the list of files, you can 
eliminate the list entirely like this (again untested e-mail Lingo):

listAsString = ""
repeat with i = 1 to the maxInteger
  thisFileName = getNthFileNameInFolder(, i)
  put (thisFileName & return) after listAsString
end repeat
delete the last char of listAsString
member("").text = listAsString

Re: Re: timeout to child (was loop every hour)

[Irv Kalb]

Hi,

In Director, to create objects you use parent scripts (or behavior 
scripts).  The passage you quoted below refers to the fact that 
within a parent or behavior script, you can create a timeout object 
in one handler (also known as a method), and set the target (the 
method to be called back when the timeout occurs) to be another 
method within the same script.  You do this by specifying the name of 
the target method, and passing "me" as the target object.

Here's some code from a typical parent script - let's call it MyTimer.

on new me
  return me
end
on mStartMyTimer me
  oTimeout = timeOut("Initialize").new(100, #mTimerCallBackmethod, me)
end
on mTimerCallBackmethod me
  timeout("initialize").forget()  -- forget the timer
end
Let's say that you place the above code in a parent script, then 
create a global object from the script like this:

global gMyTimer

gMyTimer = new(script "MyTimer")

Then, at some time, you call:

  gMyTimer.mStartMyTimer()

Then, 100 ms later, the mTimerCalllBackmethod of that object will be 
called back.

Alternatively (but similarly), if you put this code into a behavior 
and attach it to a sprite say in channel 1:

on mStartMyTimer me
  oTimeout = timeOut("Initialize").new(100, #mTimerCallBackmethod, me)
end
on mTimerCallBackmethod me
  timeout("initialize").forget()
end
You could do a

sendSprite(1, #mStartMyTimer)

then, 100 ms later, the mTimerCallbackMethod would be called back.

The key is the word "me" which refers to the current "instance" of 
the script.  Macromedia calls this instance the "child" that is 
created from a parent script or a behavior created from a behavior 
script.

Hope this helps,

Irv

Hi,

I don't understand very well how to use the #target attribute of the

is in a movie script - works great. But what does"  "The 
targetObject identifies the name of the child object that contains 
the #timeoutHandler" exactly means? The child of which parent? I 
have tried with the #timeoutHandler in a member script, but it 
doesn't seem to work. I would be grateful if someone could provide a

Re: detecting whether projector is running from writeprotected drive

[Irv Kalb]

The free FileXtra4 has a call, I think it's called fx_VolumeIsCDRom. 
I don't know what it would do with a DVD drive, but it would be easy 
for you to try it.  It also has some other calls that you could play 
around with.

Hi folks,

I want to find out whether my projector is running from a write protected

cross platform solution and in any case, an increasing number of people
have more than one write protected drive on their windows box. (e.g. both
a DVD and CD drive).
This turned out to be trickier than I thought. I felt sure there would be
some system property, or that buddyAPI or fileio would do it for me.
In the end, I've opted for fileIO, but it's a bit messy. FileIO will not
report an error if I try to open a file with the 'write' flag set to true,
which strikes me as a bug.
It will, however, cause an error if I try to create a file on a
non-writable drive, although if the drive is writable, I then have to
'clean up' and remove the dummy file that got created, which requires also
that I open it. (You can only delete a file that is open with fileIO).
This seems like a lot of messing about, but it works.
Here's my code, does anyone have a slicker approach? Suggestions for
freeware xtras are welcome.
on moviePathWritable

  f = new(xtra "fileio")
  dummyFilePath = the moviepath & "zxxz.txt"
  f.createFile(dummyFilePath)
  errCode = f.status()
  if errCode <> 0 then

return false

Re: List bracket access

[Irv Kalb]

Kerry,

The bracket syntax always gets you what is the value at the given 
location, whether it's a linear list or a property list.

Yes, you have to use getPropAt, to get the property, then you can use 
that property to get the value.

Using your example, if you do a:

  theProp = getPropAt(vpl, 1)

theProp is assigned "TB199".

Then you can use that to get the value:

  put vpl[theProp]

you get [135, 137, 0, 0, 0, 0]

I though when I did bracket access, e.g. pl[1], I would get the first
element in the list. In this case, "TB199": [135, 137, 0, 0, 0, 0]
But I'm not. I'm getting the value, i.e., [135, 137, 0, 0, 0, 0]

What's really confusing me is that I'm getting what I expect from a
higher-order list. In the example above, vpl is actually derived from a
larger list which looks like this:
pl = ["31": ["TB199": [135, 137, 81, 114, 0, 0], "TB53": [138, 158, 81,
114, 0, 0]], "n31": ["TB199": [135, 137, 0, 0, 0, 0], "TB53": [138, 158,
11, 92, 0, 0]]]
In that case, pl[1] is ["TB199": [135, 137, 81, 114, 0, 0], "TB53":
[138, 158, 81, 114, 0, 0]]
So, how do I get the entire first element--the property list--from vpl?
Do I have to cobble it together with getPropAt and bracket access (or
getAt)?
Cordially,

Re: displaying text from list

[Irv Kalb]

No, you don't want to change your original data, you just want to 
build a string with returns in it.

Here's my untested version:

on ListToString listIn
  stringOut = ""
  nItems = count(listIn)
  repeat with i = 1 to nItems
 put (listIn[i] & RETURN) after stringOut
  end repeat
  return stringOut
end
Call this routine, pass in your list, it will return a string, put 
the string into some field or text member to display it.

Re: change sprites channels

No, you can't change sprite channels, but you can change the ordering.

When you want to bring something forward, set the "locZ" property 
high.  But don't forget to reset it when the spritespan ends, or  it 
will remain in that ordering:

on endSprite me
  sprite(spriteNum).locZ = spriteNum

Re: ARRRRRRRRGHHHHHH!!

[Irv Kalb]

I'll throw out a guess based on your description.  Here's my understanding:

You are attempting to create a QT object.  In the "new" handler of 
your script, you are checking for QT being installed.  In the case 
where it is not installed, your new method is issueing a go to frame 
xxx.

My guess is that you are creating the object like this:

global gQTObject

gQTObject = new(script "QTObject script")

then the sprites are trying to use the global gQTObject.

If this is the case, then your problem is that you are issueing the 
go to before the gQTObject is assigned a value.  That is, in the code 
of the "new" handler, you are doing the go to before you do the 
"return me".

If this is the case, then you should split up the code into a new 
handler and a separate handler to check for QT:

on new me
  -- any initialization code that runs once
  return me
end
on IsQTInstalled me
   if  then
  return TRUE
   else
  return FALSE
   end if
end
Then you initialization code would be something like this:

  gQTObject = new(script "QTObject script")
  OK = gQTObject.IsQTInstalled()
  if not(fOK) then
 go frame "Missing QT"
 return
  end if
  -- Carry on 
If I am wrong about your structuring, please post some code so we can 
see what is happening.

Re: wait

[Irv Kalb]

The best way to achieve something like this is to do move the sprite 
at every frame event.  Since I don't know what your starting and 
stopping "triggers" are, I'll just give you the basic idea:

property spriteNum

on exitFrameme
  sprite(spriteNum).locV = sprite(spriteNum).locV + 1
end
This will move the sprite 1 pixel every frame.   So, the animation 
will run at whatever the frame rate is.
