It may make legal systems work smoothly to uphold a fiction that people read, understand and agree to the terms in EULAs, but it is simply untrue in the majority of cases. EULAs are most often simply agreed to by the users without being read. Last week I bought a fire-wire cable for my iPod at an Apple dealer in Melbourne, Next Byte. I paid for it, put it into my backpack and started to leave, but the salesman rushed to stop me and asked that I sign long cash register docket that included I hereby accept the terms and conditions... There were five terms and conditions on the front of the docket and 14 on the back, including one that uses effect when the clear intention is affect. There was no pretence that I should read the terms and conditions prior to signing my assent. A contract for purchasing a fire-wire cable? Bloody hell, we've gone mad! I signed it (without reading it) because I wanted the docket as a curio, but I dare say it will simply be the first of many that I am expected to sign. The docket says repeatedly that Full terms and conditions can be found on www.nextbyte.com.au. Does that imply that there are more? I couldn't find any on that website... In Australia purchasers have a number of statutory rights that can not be waived. Many contracts of sale attempt, knowingly or not, to bypass, diminish or distract from those rights. Item 7.4 of the terms and conditions is that The customer has not relied upon any representation made by Next Byte or upon the skill and judgement of Next Byte..., so even if you did, you didn't (even if you think you did because you didn't read the document that says you didn't.

Re: Ensuring numeric input
Thanks for the suggestions, but unfortunately it doesn't seem to be anywhere near that easy. A user can put the insertion point within a number and so I need to check before the character is entered whether the value will be a number after the new character is added at the insertion point. The new character may be at the start of a numeric string, in the middle or at the end. I can't find an easy function that gives the insertion point relative to the selectedLine. Most of the complexity of my script is in deciding where the insertion will be made in the line of interest. Still lacking a simple solution...

Re: animate light to dark
Thanks Scott, your script works very nicely with small images. Unfortunately, when I make the image as large as I want (about half of the screen) it still shows flickery lines as it animates. However, I've tried it on the Macs and PCs that the students will be using and they are perfectly acceptable. It looks like my Mac has fallen a bit too far behind the times! In a way, that makes things easy for me: if my stacks work well enough here, they will certainly work well enough in the student labs.

I also need to be able to respond to messages while the change in darkness is occurring. This last line is a significant hurdle. Being able to respond to messages means you can't use any of the built-in transitions. So you are correct to attempt to build the transition yourself. I've tried playing with fill colors of buttons and fields and with blendlevels of an image. I also tried the straightforward approach of simply stacking a sequence of buttons with different fill colors and hiding or showing them in sequence. For every approach I've tried the transitions are good enough with small areas, but when the objects are made large enough for my purposes they are slow and yukky. Doing visual changes over large areas does indeed require more overhead/resources, as will accounting for a lot of controls. As far as what you describe above goes, here are some more efficient options: 1) use a large image set to solid black (or whatever color is appropriate), and set its blendLevel repeatedly from 100 to 0 and then back to 100 again. Something like: on mouseUp initFader fadeCard end mouseUp on initFader put into fCount set blendLevel of img myFader to 100 end initFader local fCount on fadeCard if fCount = then put 1 into fCount set the blendLevel of img myFader to abs(100 - (fCount * 5)) # ADD YOUR ROUTINES HERE if fCount 40 then add 1 to fCount else initFader # MAKE CERTAIN MYFADER IS NOT VISIBLE exit fadeCard end if send fadeCard to me in 10 millisecs end fadeCard 2) use a button (with all visible properties disabled) as an image display and set its icon repeatedly to a sequence of images as above (solid color images will be the most efficient) 3) depending on what's happening on your card, you might be able to repeatedly set the backColor of the card from light to dark and light (as above) but obviously this will not obscure any controls on the card 4) you might consider giving up the fade transition all together and instead simply lock the screen while popping up a separate activity window that displays an animation to draw users' attention away from the updating window Hope this helps.

animate light to dark
Dear all, I am trying to get a smooth animation of a background going from light to dark (and vice versa), but I'm having trouble making it fast enough, smooth enough and flicker-free. I think it is something to do with screen redraws in OS X (see Jim Hurley's BZ entry 2639), but maybe it's more general. What I need is to have a large dark region behind some images get light over about half a second so that the transition doesn't look too amateurish. I also need to be able to respond to messages while the change in darkness is occurring. I've tried playing with fill colors of buttons and fields and with blendlevels of an image. I also tried the straightforward approach of simply stacking a sequence of buttons with different fill colors and hiding or showing them in sequence. For every approach I've tried the transitions are good enough with small areas, but when the objects are made large enough for my purposes they are slow and yukky. I've tried fiddling with unlock screen commands and with wait commands, and while they are necessary for intermediate stages to be visible, they don't fix the problems. Does anyone have a suggestion that might help? I've experimented with timing screen redraws and found that when only a small area is changed they occur almost instantly, but when a large area is changed they take much longer (I don't want to say how long because it will make me want a new Mac ;-) Does it seem strange that the time needed for a screen redraw scales with the area of the control that has changed its appearance? I would have thought a redraw would be a redraw of the whole screen and so it wouldn't make any difference whether the alteration was of a small area or large. Thanks for any help.

Re: Praise: Rev Documentation to the rescue
final iteration and then ends. If you specify an increment, the increment is added to the counter each time through the loop, rather than the counter being increased by 1. (The increment is not treated as an absolute value: if you're using the down to form, the increment must be negative.) As with the for number times form described above, the startValue and endValue are evaluated when the loop is first entered, and are not re-evaluated as a result of any actions performed in the statementList. Use one of these forms if you want to perform an action on each member of a set, and you need to refer to the member by number within the statementList. The following example loops through all the controls on the current card. The counter x is 1 during the first iteration, 2 during the second, and so on: repeat with x = 1 to the number of controls show control x end repeat The following example loops backwards through a set of lines. The counter myLine is 20 during the first iteration, 18 during the second, and so on: repeat with myLine = 20 down to 1 step -2 put myLine end repeat Note: It is possible to change the counter variable in a statement in the loop. However, doing this is not recommended, because it makes the loop logic difficult to follow: repeat with x = 1 to 20 -- this loop actually repeats ten times answer x add 1 to x -- not recommended end repeat The for each form: The for each chunkType labelVariable in container form sets the labelVariable to the first chunk of the specified chunkType in the container at the beginning of the loop, then sets it to the next chunk for each iteration. For example, if the chunkType is word, the labelVariable is set to the next word in the container for each iteration of the loop. Use the for each form if you want to perform an action on each chunk in a container. This form is much faster than the with countVariable = startValue to endValue form when looping through the chunks of a container. The following example changes a return-delimited list to a comma-delimited list: repeat for each line thisLine in myList put thisLine comma after newList end repeat if last char of newList is comma then delete last char of newList The for each element labelVariable in array form sets the labelVariable to the first element in the array at the beginning of the loop, then sets it to the next element for each iteration. Important! You cannot change the labelVariable in a statement inside the loop. Doing so will cause a script error. You can change the content of the container, but doing so will probably produce unexpected results. Use the for each form if you want to perform an action on each element in an array. The following example gets only the multi-word entries in an array of phrases: repeat for each element thisIndexTerm in listOfTerms if the number of words in thisIndexTerm 1 then put thisIndexTerm return after multiWordTerms end repeat Note: The repeat control structure is implemented internally as a command and appears in the commandNames. Changes to Transcript: The ability to specify an increment for the repeat with counter = startValue to endValue form was added in version 2.0. In previous versions, this form of the repeat control structure always incremented or decremented the counter by 1 each time through the loop. -- Michael J.

partial workaround for cross-platform fonts
I think that Phil might be onto a good workaround for cross-platform fonts. He suggested an image of a fld instead of the fld, and that should be perfectly OK for any locked fld. It makes the stack bigger, but mostly that doesn't matter. I've made a button that puts a snapshot over each locked, visible fld and keeps a record in order to be able to remove the images as needed. It seems to work well on one platform (Mac) but I can't conveniently check that the result works on any other. I think it should. The script is below. Just put a button onto the first card of a stack and put the script into it. A click should overlay the appropriate flds with images, and an option-click should remove the images. Two questions: 1. Does it work for others? 2. Can we optimise the script to make it into a generally useful workaround?

Oh dear, oh dear oh dear! What is it with people and the docs? The docs work perfectly well when you know where to look for information.

In Rev it is very easy to experiment with commands to see how they work. Try it. In Rev it is fairly easy to guess what a command might be. Just try it out and see if it works. If it doesn't then type it into the dictionary filter and see what comes up. This list is part of the effective documentation of Revolution (look up effective keyword in the dictionary ;-).

Re: Slider values
Well done Brian. Yes, setting the (invisible) lineIncrement property to zero fixes the numbers. I didn't notice that the little ticks were wrong. I don't know how to fix them. Your initial comments regarding a new user are exactly my sentiments. There are a couple of bugs in scrollbar objects in addition to such unexpected behaviour. I would like to see them cleaned up substantially at some stage. They are awkward to use in any quantitative way because their lineInc, pageInc and numberFormat properties are all interlinked.

Re: coding challenge idea
My son enjoyed looking for words in word-search puzzles, and they seemed like a good learning tool that could be made better with some extra levels of interaction. A word search-based language and spelling tool might make a good coding challenge and group project. I started to make one a few years ago and there seemed to be plenty of scope for using Revolution's strengths. The end result might be a good gift for primary schools. Word search puzzles are arrays of apparently jumbled letters that contain a specified list of words (see http://www.thepotters.com/puzzles/squaredancing.gif for an example). I would propose that the completed application would have at least the following features: 1. The ability to rearrange word squares automatically so that users can search for the same list of words repeatedly. 2. The opportunity for the user to manually arrange some or all of the words to make their own word search square for others to solve. 3. Prepared lists of words (thematically arranged?) and the option for the user to make their own lists. 4. Sound files to speak the words in the search list so that users can learn unfamiliar words. 5. An option for the user to record sound files of their own words so that their own word lists can be spoken by the program. 6. A timing function so that the challenge can be increased, or the game can be made competitive (for the boys...). This list of features would make for several independent coding challenges, and thus, of course, for many opportunities for participants and lurkers to learn coding approaches. What do you think?

Too little space leads to too many spaces
Yesterday I encountered an oddity when I started to work on a Rev project: I started to get repeating space characters in the script editor. When I closed the script the problem seemed to go away, at least until I focused on a field when the spaces reappeared. My keyboard looked fine, and so I switched to another app and there seemed to be no problem... until I clicked in a editable place. I guessed that Rev had gone mad and so I quit it. That didn't fix the problem so I restarted the computer, which did. Today I started the same Rev project and immediately found the same repeating space characters appearing in a field, and in my other apps. Oh no, a Rev bug bites? No!. It turns out that when I started to work with Rev each time I got out my project workbook and put it in front of the keyboard. The book didn't press the space key on that keyboard, but I have a second keyboard behind my monitor simply to act as a USB extender and when I put the workbook in front of my primary keyboard, I was pushing the keyboard back a bit which pushed the monitor back a bit which pushed some CD covers onto the space key of my USB extender keyboard! -- Michael J.

I think your head can be protected from hurt if you consider the proof by Gödel that no logical system can be both complete and internally consistent. Thus we shouldn't expect our mental logical system to be able to deal with everything without throwing up the odd paradox.

erratic screen updates (was Slow screen lock/unlock)
OK, thanks to all who helped me. The suggestions of Malte Brill, Jim Hurley and Richard Gaskin were particularly useful. I've now done some more fiddling around, and it seems that Jim is right: my problem is the same as that he was battling previously. Malte's suggestion to use messages and a flag rather than an if in a repeat did indeed speed up my display. Richard's suggestion of a wait with messages also sped up the original script. My conclusions are: 1. There are few, and erratic screen updates in a repeat loop. This script results in the display of only two numbers on my system: on mouseUp put 0 repeat 100 add 1 to msg end repeat end mouseUp 2. A redraw can indeed be forced with a wait. If I add wait 0 or unlock screen within the loop then all of the expected numbers flash past rapidly. I didn't see any difference between wait with messages and a simple wait. 3. Lock screen does unexpected things. If the loop in the script is add 1 to msg; unlock screen then it works well, but if it is lock screen; add 1 to msg; unlock screen then only about every 7th number appears. 4. Completion of a handler only forces a redraw if there is a wait command. Thus the following handler gives only a couple of numbers: on mouseUp put 0 addOne end mouseUp on addOne add 1 to msg if msg100 then send addOne to me end addOne If a wait is added by making the line into if msg100 then send addOne to me in 0 millisecond then all numbers are displayed. Here is an improved version of my point animating test script (you'll need a button for the script, two graphics and one field): local timelist on mouseUp set the flag of me to not the flag of me if the flag of me then put empty into timeList set the l of me to the left of grc 1 set the w of me to the width of grc 1 set the t of me to the top of grc 1 set the h of me to the height of grc 1 if the flag of me then animatePoints if not the flag of me then put reportTimes() into fld 1 set the clipboardData[text] to fld 1 end mouseUp on animatePoints --make randomly placed points put empty into myPoints repeat 100 put the l of me + random(the w of me) into x put the t of me + random(the h of me) into y put x,y return after mypoints end repeat --display them set the points of grc 2 to myPoints if the flag of me then send animatePoints to me in 20 millisecond put the milliseconds return after timeList end animatePoints function reportTimes put 0 into prevTime put line 1 of timeList into st repeat for each line ttime in timeList put ttime-st tab ttime-prevTime return after durationList put ttime into prevTime end repeat delete line 1 of durationList return durationList end reportTimes If you run it you may find, as I do, that it is plenty fast enough in bursts, but the rate is erratic, with some cycles as much as 6 times slower than the average. Overall it works in a disappointing way. This has been interesting, but at the end I still have to say that I haven't found a way to get smooth animation rates. The calculations are fast enough and the screen updates are fast enough most of the time, but every second or so there are a few slow cycles and that makes any animation jerky and horrible. -- Michael J.

When I comment out the lock screen line it takes less than one millisecond. Unfortunately, simply omitting the lock and unlock screen commands doesn't get rid of my problem. The reason I ran the test of lock/unlock speed is that the following test script animates the points at an unacceptably slow (and somewhat erratic) rate: on mouseUp --initialise some convenience variables put the left of grc 1 into l put the width of grc 1 into w put the top of grc 1 into t put the height of grc 1 into h repeat --make randomly placed points put empty into myPoints repeat 100 put l + random(w) into x put t + random(h) into y put x,y return after mypoints end repeat --display them lock screen set the points of grc 2 to myPoints unlock screen if the mouse is down then exit repeat end repeat end mouseUp Graphic 2 is set to be a polygon with its markers shown (2 by 2 squares) and its line thickness set to zero. No combination of lock and unlock or no locks makes it any better. The making of the points and the setting of the points take almost no time. The slowness is in getting it onto the screen. ...and before someone asks, no, the slowness is not related to polling the mouse: commenting out that line doesn't change the update rates.

You might be too. Are there any circumstances when you would WANT to activate the control with the click that opens the script editor in the IDE? There is certainly circumstances where it is annoying: if a button has a long-lasting script, or if the button initiates a series of message calls to part of its own script. There are at least two bugzilla reports about this behaviour, but they are resolved as not a bug (1884) and as a duplicate (1966).

Make its name DistHistoBox to match its name in my script. You will also nee to make a graphic (a line, anywhere initially) called DistHistoLine.

Put a text box at either end of the histo box to hold the scale extreme values and call them DistMin and DistMax as appropriate. You then need two scrollbars called mean and stdev.

At the moment I toying with the idea that students will be required to make reports that can be distributed to the class as learning resources; having to teach something is a terrific incentive for learning it first!

Agreed wholeheartedly. Education-related work was the largest single set of tasks folks did with HyperCard, and for all the tools that have come out since there remains an unaddressed gap which may be an ideal focus for DreamCard. But moving beyond simple questions models like multiple choice is difficult. The AICC courseware interoperability standard describes almost a dozen question models, but most are variants of choose one, choose many, closest match, etc., sometimes enlived by using drag-and-drop as the mechanism for applying the answer but not substantially different from what gets tested with a simple multiple choice in terms of truer assessment of what's been learned. The challenge is to find more open-ended question models which can still be assessed by the computer. For example, the most open-ended question is an essay, but I sure don't want to write the routine that scores essays. :) What sorts of enhanced question models do you think would be ideal for computer-based learning? -- Richard Gaskin Fourth World Media Corporation -- Michael J.

Look at the output with the thumb in the region just before the value shown changes. No, not YOU being stupid, the slider is stupid. I have to admit that that alleged stupidity of the slider is my opinion and it is not shared by Scott Raney (see bug #347). Set the numberformat of the slider to 0.00 and look at the results. You can get it to work how you might expect by using round(the thumbposition) in your script. But there is more to it... Sliders and scrollbars are far more difficult to work with quantitatively than you might think. The pageIncrement property doesn't determine the increment obtained when you click on the grey bit, it is really the pageInc minus the lineInc. The default lineInc for a new slider object is set to 0 (you can't see it in the object properties inspector but you can query it or set it with the message box). However, it changes if you change the numberformat (Value format) of the slider! Thus if you have a slider with the numberformat set to show some decimal places you will see that clicking in the grey area of the slider gives you a change of value that is LESS THAN the pageInc (On bar click) value. Of course, how much less than the expected value depends on the particular numberformat. I find this situation to be awkward every time I try to use a scrollbar or slider object. Just yesterday I posted this to the Improve-rev list: At 3:27 PM +1000 28/7/04, Michael J. Lew wrote: Did you know that the change in thumbposition that occurs when you click in the grey area of a scrollbar object is NOT the pageIncrement? It is actually the pageIncrement minus the lineincrement. That is not new with the beta, and it is not what the documents say but you can confirm that quite simply: Making a new scrollbar object, set its endValue to 100, its startValue to 0, its lineInc to 1 and its pageInc to 10. Now give it a script On mouseUp; put the thumbposition of me; end mouseUp. Now click away and see that the increment is 9, not 10. I posted this as a bug a long while ago (see BZ #347) but was told that it is not a bug because the GUI standard has it that a page should scroll to have the new first line the same as the previous last line (i.e. the page increment is a page minus one line). However, the documentation has not been corrected. I think that the argument for having page increment not equal to the pageInc is very weak. It doesn't seem sensible to have to work around the odd values every time we make a scrollbar to control something just to make the conformance with GUI standards for scrolling pages of text automatic. I am doubly-sure that the situation is bad because most often when text is being scrolled it is via a scrolling field rather than a separate scrollbar object and so it should be possible to have scrollbar objects behave well and fields behave differently. What do you think? Should the behaviour of scrollbar objects be changed so that the pageIncrement property is what it says or should the docs be adjusted to reflect the confusing reality? -- Michael J.

Re: Alpha Channel?
You CAN permanently re-size an image with only a little bit of indirection. Make the image the size you want, then make a new image and type these two lines in the message box: set the rect of image 2 to the rect of image 1 set the imageData of image 2 to the imageData of image 1 Now image 2 has its natural size set to its current size. Go to another card in the stack and return and you will find image 1 has reverted to its inital size but image 2 has stayed just how you want it. (It works because the imageData is the pixels as displayed, not the pixels at the original image size.) Hope that helps. Graham wrote: It drives me crazy too because it's not clear how you turn off the 'revert to original' feature permanently, for example if you want to repurpose the image entirely and completely lose the original size. I mean, if I'd altered the shape of an image in a graphics package, I wouldn't expect the 'original size' to haunt me forever, would I? I don't see an original size as a 'natural' size; it's just what I started with, neither more nor less. -- Michael J.

If this is a button, you won't get the message. If it is an editable field, you will. Since all controls on Windows can be focused, the trick is to make sure that the lowest-level, traversalOn control is a button. On a Mac, however, buttons cannot receive focus and the first editable field will receive focus instead. On Macs, you have to use a hack -- either make sure none of your fields are focusable, or else hide an editable field offscreen somewhere whose layer is set to 1. Then that hidden field gets the focus and your card looks untouched. For your problem though, the hack won't help because the offscreen field will receive focus and trigger messages anyway.

Problem 2. The checkmarks show up as !c rather than as checkmarks. Something bad has happened to the conversion of !c into a checkmark.

Rev replace PowerPoint from Rev List
into Revolution. For example, the geometry manager is useful switching from edit mode to full-screen mode and the backdrop property can instantly deal with any mis-match between stack and screen proportions. Groups are a natural way to deal with the variety of slide templates. Slide transitions are built in. Image importing needs only a convenient way to get images from the clipboard. Animations are readily constructed using the animations manager. Basically, the similarity of the card and slide metaphors is such that using Revolution to make slideshows is a natural. Importantly, in order to be useful to those like me who already code in Revolution, the project needs only to supply some templates and standard slide components and behaviours; the rest can be scripted directly in Revolution. Thus such a project can be useful even at a minimal stage of development. Extra capabilities can always be added by anyone who has Revolution because the project would be naturally modular. In my imagination we will end up with a standalone application that makes and displays slideshows just like PowerPoint, and a version that runs within Revolution that will make open-ended multimedia presentations convenient for Revolutions scriptors.

Re: Building serious scientific applications with RunRev...
Absolutely! I use Revolution as my ONLY programming tool for both teaching and scientific applications (and sometimes both combined in a single project). I have built several projects using matrix algorithms from the Numerical Recipes book (Press et al.) and facilitated that by making a fortran and pascal to transcript (partial) converters. Specific programs that work well are a partial differential equation-based numerical simulation system (both Runge-Kutta and Rosenbrock stiff integration routines), a statistical program that does simple Student's t-tests and the more widely appropriate permutations tests, a not-quite perfect (yet) curve-fitting program along with a wide variety of other smaller applications. Relevant built-in functions in Revolution make the building these types of routines quite straightforward. For instance the random() function returns reliably random numbers that have no bias or correlation. I recommend that if you are already familiar with Revolution then you should have no qualms concerning its applicability to scientific computing problems. I can't comment specifically on imaging, psychophysical or colour projects, but I'd certainly give it a go in Revolution before trying to deal with C. My programs are generally a bit slower in execution than commercial programs with similar functionality, but they are certainly fast enough for my purposes and the speed difference is nowhere near great enough to counterbalance the time that learning C might take.
