Re: [Flashcoders] Question about AS3 components
What class are you subclassing to make your component? UIComponent defines a protected measure() function which some other internals use to figure out how big a component is. Maybe you need to implement an override of that? The docs show InteractiveObject having a focusRect property, but they don't give much detail about it. If you're using Flex classes, remember that FlexBuilder comes with the source code for the Flex classes. I have had to resort to reading Flex class source many times to understand things that the docs don't describe well. :-/ Dave On Tue, Mar 17, 2009 at 10:31 AM, Eric E.

Re: [Flashcoders] Advice on creating random grid of pairs for a game
My first thought for your algorithm is to essentially follow the solution path that your user might end up taking. Your user will be clearing areas out, opening them up. Your algorithm could start with an empty grid and fill in around a starting seed, growing the tile array outward. 1) empty grid 2) generate random sequence of pairs with the blank embedded in it, such as 4,4,27,27,1,1,36,blank,36, etc 3) choose random location for first tile, and place it there, and take it off the pair queue. 4) choose an unfilled location which is 4-connected to any filled location, and put the next tile from the queue in it. 5) repeat 4) until the queue is empty. In this system, putting the blank in a location counts as filling that location, so the value for blank needs to be different than the initial values in the grid. So for example, if -1 means uninitialized and 0 means blank: -1,-1,-1 -1,-1,-1 -1,-1,-1 then -1,-1,-1 -1,-1,04 -1,-1,-1 then -1,-1,04 -1,-1,04 -1,-1,-1 then -1,-1,04 -1,27,04 -1,-1,-1 then -1,-1,04 -1,27,04 -1,27,-1 then -1,-1,04 01,27,04 -1,27,-1 then -1,-1,04 01,27,04 -1,27,01 then 36,-1,04 01,27,04 -1,27,01 then 36,00,04 01,27,04 -1,27,01 then 36,00,04 01,27,04 36,27,01 This guarantees that a solution exists, because the algorithm essentially traces out the solution as it generates the level. This presumes that players are not allowed to move tiles around yet leave them on the board while solving the puzzle - it assumes that tiles just disappear from the grid when the user selects a pair which has a clear path between it, and that's the only interaction allowed. If they can slide them around, my algorithm will still produce solve-able puzzles, but they won't be as difficult as they could be, I think. :) Interesting problem!

Re: [Flashcoders] where did the mouseX go?
mouseX and mouseY are member variables of the Sprite class. You don't need
to import member variables, only classes. Once you import the Sprite class,
all the members come with it.
replace your mouseX and mouseY imports with:
import flash.display.Sprite;
and you'll be golden.

Re: [Flashcoders] Advice on creating random grid of pairs for a game
Jonathan, When you match a pair, you pull them off the grid. Therefore after removing the pair of 2s, there are only empty squares in the path between the 1s.

Re: [Flashcoders] Advice on creating random grid of pairs for a game
In the following grid, all bs are 4-connected to the one a: -, b, - b, a, b -, b, - So for the sample grid -1,-1,-1 -1,-1,04 -1,-1,04 the cells which are 4-connected to the initialized cells are here marked with xx: -1,-1,xx -1,xx,04 -1,xx,04 In other words, the cells to randomly choose the new tile placement from are the ones at the boundary of the already-initialized region. In the initial description of the problem it sounded like valid paths did not include diagonals, which is why I say 4-connected. If diagonals are OK, use 8-connected.

Re: [Flashcoders] Best way to access my main class?
My preference is usually option 3, using an event. It means you can use
your ball in other situations, where that call back to the root may or may
not be necessary. Regarding cleaning up references in event listeners, you
can use a weak reference when you call addEventListener(). Also, I often
find that existing flash or flex events match the nature of what I want to
express, so I re-use theirs sometimes which saves writing a new event class.
Option 4 would be to make MyGame implement some interface (Game? IGame?)
which specifies that function. Then the BouncingBall constructor is passed
a reference to the interface instead of the whole MyGame class. Same as
option 2, really, but this way it's plausible that you would implement the
interface with some other game-like class and use BouncingBall in that.
Option 5 would be to pass a Function reference into the constructor of
BouncingBall. This is very generic, like the event solution, but has a few
downsides: 1) function specifications are not maintained by the compiler
when you pass Function references, so if you write a bug into the call of
the function, you'll get a run-time error instead of a compile-time error.
2) Exactly one object can listen for this function call, unlike an event,
which can be listened for by any number of clients.
I often use Option 5 for success and failure callbacks when something won't
complete right away.

Hey, FlashCoders.
I'm wondering if you can help me out with a general style question that I
keep running into. Let's say I've got a setup like this...
class MyGame extends MovieClip
- It creates a camera sprite that I can add children into
- It then creates a Bouncing Ball object with the camera sprite as
the parent to use.
class BouncingBall
{
public function BouncingBall(parentToUse:DisplayObjectContainer)
{
// Create member variable _mySprite:Sprite and add it to my parentToUse
//...
}
}
For reasons I won't get into unless you're really interested, BouncingBall
does NOT extend Sprite, it simply contains a sprite.
So MyGame has a camera as a child. That camera has my
bouncingBall._mySprite
as a child.
The question is this: I want the BouncingBall sprite to occasionally call a
function in MyGame. What's the best way to do this?
*Option 1:* Within BouncingBall, just call...
MyGame(_mySprite.root).foo(_myVar);
This works, but it strikes me as a little unnatural, since I have to dig
into my member variable and get its root. Also, I'm not sure this works if
my game were to be imported by some larger, wrapper class.
*Option 2: *My constructor for BouncingBall should contain two variables
public function BouncingBall (var parentToUse:DisplayObjectContainer, var
gameApplication:MyGame)
I store gameApplication as a member variable, and use it later...
_myGame.foo(_myVar);
This is my current solution, but the idea of passing a parent and the game
application to the constructor strikes me as slightly redundant, and, like
Option 1, it tightly couples my BouncingBall object to my main application.
*Option 3:* I create a custom event, dispatch that event, and create a
listener in MyGame rather than call a function directly.
I'm guessing this is the best way to go theoretically, and will allow me to
reuse my BouncingBall object in other applications, but it's a lot of extra
code, and I constantly worry about not property cleaning up event
listeners.
I'm sure all of you have encountered this situation before. So what do you
generally do? Is there a fourth, totally obvious option that I'm
overlooking?
Thanks!

Re: [Flashcoders] top down plane games
I may be misunderstanding the trouble you are having, but are you looking
for sine and cosine?
var velocity: Number = 3; // Absolute velocity, regardless of direction
speedX = velocity * Math.cos( cursorAngle ); // X component of velocity
speedY = velocity * Math.sin( cursorAngle ); // Y component of velocity
Or, since you are starting with a dx,dy and computing an angle from that,
you can just normalize the vector to whatever length (speed) you want.:
var velocityVector: Point = new Point( dx, dy );
velocityVector.normalize( velocity ); // Set length of vector but preserve
direction
speedX = velocityVector.x;
speedY = velocityVector.y;

Then, when it comes to creating the background scrolling below you
look,
don't have your background move at all. Only have the things that would
actually move in real life (planes and tanks and whatever) move.
Instead, make your Camera sprite scale and/or move itself to track your
plane (or, even better, a point a couple hundred pixels in front of your
plane.) That will make it look like the background is moving, but it's
really staying in place. And it will simplify your planes and tanks and
bullets, because you can basically just look at each sprite's position
and
velocity, without having to try and somehow compensate for a magical
moving
background.
For development purposes, by the way, I would start your game by not
having
the camera move at all, and just making sure everything works right in a
tiny little world the size of your screen. Once that's working, then you
can
enlarge the bounds of your world and start moving your camera around.
Good luck!

Re: [Flashcoders] get PROP from obj.PROP
private function assignContent( parentObject: *, memberName: String ): void is what your function needs to take, and you would call it like: assignContent( msg, ONE ); With assignContent( msg.ONE ) as you have it, the reference to the object stored in msg.ONE is read from msg before and only that object reference is passed to assignContent(). There is no obvious way to recover that connection just from the argument inside the function. References are one-way connections.

Re: [Flashcoders] ActionScript syntax enhancements?
Dunno if you're going to implement [Bindable], which is I guess part of
Flex, but if you do...
https://bugs.adobe.com/jira/browse/SDK-14475 and
https://bugs.adobe.com/jira/browse/SDK-9804
describe the fact that we can't use data-binding to watch the changes of
read-only properties. This ability would allow us to more nicely
encapsulate our code while still getting the ease-of-use of data binding.
In response to Manish... if you make your public getter and setter contain
only pass-throughs to your private variable, why not just make the variable
public?

I'm currently in the process of writing a compiler for
ActionScript 3.0.
(In case you're interested, the development snapshot at
http://www.swftools.org/download.html already contains
a pre-alpha command-line tool, called as3compile(.exe))
Now, I'm thinking about adding an extended mode to this
compiler, which will support some additional convenience
features which are not currently part of the ECMA spec.
The first enhancement I can think of is a language extension called
'properties'.
private var _myProperty:int = 0;
public function get myProperty():int
{
return _myProperty;
}
public function myProperty(value:int):void
{
_myProperty = value;
}
This pattern is so common, it could be a language feature.
public property myProperty:int = 0;
There, much better. You can override the property in a subclass, of course.
override public property myProperty:int = 1;
Or:
override public property myProperty:int {
var _myProperty:int = -1;
function get ():int {
return _myProperty == -1 ? Math.floor(Math.random() *
0x100) : _myProperty;
}
function set (value:int):void {
_myProperty = value;
}
}
Then you can make them read-only, write-only, or read-write.
Okay, maybe that's overkill. But I'm tired of having to write 7 lines
of code just to add one property to a class.
Another one is events. I wish events were part of the interface of an
object, and I wish all objects were event dispatchers (i.e. Object and
EventDispatcher were one). This is much too advanced to call it a
small extension to the language though.
There's probably a lot of small things you could pick up from other
languages like C, Java, etc.

Re: [Flashcoders] Custom eventListener
An event is just a message object. Just because one gets created
successfully does not mean it is being delivered. dispatchEvent() is a
method of the EventDispatcher class, which is a superclass of many classes,
including DisplayObject. You need to listen for the event (with
addEventListener()) on the same EventDispatcher where the event was
dispatched. (Except in the case of events that bubble, but that's another
topic.)
For example:
public class MyWindowHolder extends Sprite {
public function init(): void {
var a: MyWindow = new MyWindow();
a.addEventListener( MyEvent.EXCLAMATION, onExclamation );
}
private function onExclamation( event: MyEvent ): void {
trace(ouch!);
}
}
public class MyWindow extends Sprite {
private function injury(): void {
this.dispatchEvent( new MyEvent( MyEvent.EXCLAMATION ));
}
}
Hope this helps,
Dave

Re: [Flashcoders] Custom eventListener
I use custom events mostly when I have data to pass through the event which doesn't fit nicely into some pre-defined one. For instance, we have a HighScoreEvent which has the number of points and the time it took to finish the game. Also, it is good practice to define your own Event subclass(es) to contain the names of the events. Otherwise you are left with this kind of thing: addEventListener( injury, onInjury ); dispatchEvent( new Event( Injury )); And you have a bug caused by a spelling error. If instead you do this: addEventListener( InjuryEvent.INJURY, onInjury ); dispatchEvent( new InjuryEvent( InjuryEvent.lNJURY )); The compiler will catch the spelling error for you.

Re: [Flashcoders] passing on ... args
Ooh! Ooh! I just wrote this a few days before you asked. Here's my
solution:
public function call( rpcName: String, responder: Responder,
rpcArgs: Array ): void {
// NetConnection.call() takes a variable number of arguments after the
// RPC call name and the responder. To make a pass-through call from
// one such function (this function) to another
(NetConnection.call()),
// we must make an array of ALL arguments to the target function and
// then call apply() on the Function object we wish to call
(_nc.call).
var callArgs: Array = [rpcName, responder].concat( rpcArgs );
// Function.apply() also wants a this reference, so we pass _nc in
too.
_nc.call.apply( _nc, callArgs );
}
As Meinte says, it isn't worth the mess, so I don't use ... in my own
code. The contents of the function would look exactly the same if you
changed the call signature to match NetConnection's:
public function call( rpcName: String, responder: Responder, ... rpcArgs
): void
And then it's a proper pass-through.
With Latcho's example:
testargs( a,b,{z:'zz'},[1,2,3],c )
private function testargs(... argsA):void
{
trace(#args_A:, argsA.length)///
traces: #args_A: 5
passingArgs.apply(this, argsA)
}
public function passingArgs(... argsB):void
{
trace(#args_B:,argsB.length) ///
traces: #args_B: 5
for(var i:int=0;iargsB.length;i++) { trace(argsB[i]); }
};
If passingArgs() isn't a member function of some class, I'm not sure what
you pass as apply()'s first argument, possibly null?

Re: [Flashcoders] frameworks and flash
Actually, Cairngorm does allow arbitrary mappings from events to commands, it does not require 1-to-1. The FrontController's addCommand() function takes an event name (String) and a Command class. In our app I have used the same event with different name-constants to run different commands, like so: addCommand(FollowingEvent.ADD, AddFollowingCommand); addCommand(FollowingEvent.REMOVE, RemoveFollowingCommand); In the constructor of FollowingEvent I take a type (String) parameter which I pass through to CairngormEvent's constructor. Dave And one more thing I dislike is the 1 on 1 mapping of Events and Commands. From what I've seen in their docs and samples they use a different Event class for every Command, which IMO makes no sense. GetUserEvent UpdateUserEvent DeleteUserEvent CreateUserEvent And the static constants are stored someplace else, can't remember but think it was the Controller (that extends FrontController). Rather than having 4 Event classes for each Command I prefer 1 Event class: UserEvent which has as many static constants as required: public static const GET_USER:String = getUser; public static const UPATE_USER:String = updateUser; public static const DELETE_USER:String = deleteUser; public static const CREATE_USER:String = createUser; Again this is inline with what is already present in the Flex framework: MouseEvent.CLICK MouseEvent.MOUSE_DOWN MouseEvent.MOUSE_UP etc.. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] Flex vs. Flash
If you are building an application-like user interface with buttons, forms, dialog boxes, etc, I would really recommend Flex. MXML lets you write such things very concisely. It has a powerful layout engine and a nice set of containers which automate a lot of stuff you'd have to write by hand otherwise. If your program is mostly animation and graphics, I guess Flex wouldn't have a lot to offer. Flex is certainly a big chunk to add to your binary size, so I wouldn't choose it lightly. We wrote playcrafter.com in Flex and have no regrets about the choice. You can certainly write anything in plain AS3 that you can write in MXML with the Flex library. You just need to decide if the code in the Flex library is code you'd need to be writing anyway.

Re: [Flashcoders] frameworks and flash
We have been using Adobe Flex for the past year and have really liked it.
It would be hard to call it blazing and bloat does seem like it might
apply to some extent, but on the other hand it does so many nice things for
us it is hard to argue with. MXML is very powerful, but there is certainly
a big learning curve. For basic stuff, buttons and containers and text,
it's easy to get started. There are lots of subtle details though, so when
you start wanting to do things in ways the Flex authors didn't anticipate it
often takes experimentation to find a way that works. The Flex framework
code is open source at least, so you can always dig into that and see what
it's doing.
We have also used Cairngorm, with mixed results. Cairngorm doesn't really
give you much code, it is mostly a set of design patterns. Some of the
important code it does give is a controller which connects Cairngorm
Events to Cairngorm Commands. Cairngorm events inherently know their
dispatcher, which is a singleton, so you can just fire off events like so:
new SaveGameEvent(game, user).dispatch();
and the controller connects that to the appropriate SaveGameCommand. We've
come to the conclusion that Cairngorm is great for situations where most
user actions imply immediate communications with a server, but not so useful
for situations where user actions are just manipulating data internal to the
.swf. We have ended up using Cairngorm Events and Commands just on the
networking side of our app, and for everything else we do more of a basic
Model/View pattern.
I don't believe Cairngorm relies on Flex, but Flex gives you data binding
which works very nicely with Cairngorm. Flex data binding lets you mark
certain state variables with [Bindable] and then the compiler builds
data-change events for you. Then your view mxml classes use the data
binding syntax like Label text={game.description}/ and the view updates
automagically whenever the Game's description field changes. A Cairngorm
command might query a server and then the server-response-handler in the
command can set game.description.

No problem. A binary search is an order log(N) method for finding something in an ordered list of elements, as compared to linear search, which is order N. (N is the number of elements, in this case, font sizes you are willing to use.) You have a sequence of font sizes. For each size, it either makes the TextField too tall, or it doesn't. You want to find the biggest size which isn't too tall. The linear approach is to start from one end of the font size list or the other and try sizes one by one until the TextField height crosses the threshold. The binary approach is to try both ends first, say 1 and 50. If 1 is too big or 50 is too small, you already have your answer. If not, try the middle: 25. If 25 is too big, move your idea of biggest down to 25, and try the middle between 25 and 1: 13. Maybe 13 is too small, so change your idea of smallest to 13. Then try the middle between 13 and 25: 19, and so on. Once the two ends (smallest and biggest) are adjacent elements (say one point difference in font size), the one marked smallest is your answer. Binary search is only a little more complicated than a linear search to implement, and if you are searching over a large number of font sizes, the savings can be significant. If it's just 4 or 5 font sizes it's probably not worth the trouble. Binary search is a very classic computer science algorithm, so I'm sure you can find good descriptions on the web.

[Flashcoders] keyboard focus mouse button interaction
Hi all, I ran into an issue with keyboard focus which I don't understand, and I don't see detailed in the docs anywhere. We have a site that has games in it as well as forms, so sometimes we want game-style key handling and sometimes we want the form style, where tab or mouse clicks change focus. In many of our games you need to use the keyboard and mouse, and it seems as though every time the mouse button is pressed inside our game area (a Flex Canvas), stage.focus gets set to null, so the keyboard event listeners attached to our Canvas don't get called. My current hack to fix it is to listen for FOCUS_OUT events from the Canvas and set stage.focus back to the Canvas. That seems to work, but I wonder: 1) why Flash (or Flex?) is setting stage.focus to null when I click on my game Canvas, and 2) how to make a component (my game Canvas) such that I can programmatically set it to be focused or unfocused and disable the mouse button -based focus change. It seems funny that I have to keep re-asserting the focus. I tried listening for MOUSE_FOCUS_CHANGE events and cancelling the default action of them, but those events did not fire when the focus was changed to null. Strange. Another factor is that sometimes our games are loaded from other .swf files, and then the game Canvas can't access the stage because it would be a sandbox violation. So it seems like I can't just attach my game key listeners to the stage directly. In fact this makes me wonder if my stage.focus thing isn't going to fail as well... I suspect I need to make my game canvas implement IFocusManagerComponent or something, but before I spent too much time experimenting I wanted to see if anyone already knew the Right Way to handle this.
