I have a class that extends an object, and have declared some variables in the class code:
Code:
package {
public class myclass extends Object {
public var _test = "yey";
[Code]....
How could i get the default value of the var _test? If i try to trace directly with the class as the pointer, i get syntax error:
Code:
trace(myclass._test);
On the stage I have a movieclip by the name of rect_mc. Inside it have have a MovieClip square_mc.In the time line that I get when I double click on rect_mc (timeline of rect_mc) I have written the following code
var width1:Number;
width1 = sqaure_mc.width;
How can I access width1 from the document class?The thing that I want to is access the variable declared (width1) in the timeline of rect_mc. Just for the sake of a example only I choose the width of MovieClip.My doubt is how can access a variable declared inside the timeline of rect_mc from the document class. It could be any variable.My document class is:
package
{
import flash.display.MovieClip[code]....
I was thinking about how to streamline my code the other day and looked through my classes checking for possible memory leaks. I wonder when are variables declared inside of methods clear for garbage collection? or are they not and just hang around? For instance if I have a class like this:
[Code]...
Since the variable was declared without reference into the class how long does it stay in Flash's memory, or does it stay indefinitely because it cannot be nullified?
If we have declared some variables on a particular frame, say frame 20 in the actionscript coding window, can we use these variables defined on a frame in a class? Is there something like a global variable which must be declared to do this?The class extends to movieClip and it has been encapsulated by a movieClip which is then put on the stage to run it when the corresponding frame plays.

ActionScript Code:
var timer:Timer = new Timer(30);
timer.start();
timer.addEventListener(TimerEvent.TIMER, onTimer);
[Code]....
Now, this of course gives a run time error (access of undefined property snowSpeedX) due to the fact that snowSpeedX is declared in the function onTimer. The reason it is declared their is because i want it to change everytime and so each snowflake that falls, moves in the x axis with a different speed. If i declared the snowSpeedX variable outside of the onTimer function, i wouldnt get a different value for every snowflake, i would just get one.
So, how do i get the snow flakes to have a varying range of speeds?

View 1 RepliesI sometimes see events declared near the top of the class (i.e. below the imports but above the constructor):
/**

[Event(name="complete", type="flash.events.Event")]
What exactly is this? Is this an "import" of a certain type of event?
These two functions are taken out of my as class file, even though the setInterval is never cleared it only calls generateParticles 1 time. Someone please help me figure this out. I have been messing around with it over an hour but still can find why its only called once. emit is a private var Number declared outside the function in the class.

I've got a class where I'm using:
o.type = "focus";
o.target = "this";
dispatchEvent(o);
and then focus is a function of an object in the FLA.
I want focus to be in the AS External Class file but it won't trigger.
In my library I have:A Sprite named Emily of base-class "Character" with a sub-sprite labeled "head" of auto-generated Class "EmilyHead".A Sprite named Jess of base-class "Character" witha sub-sprite labeled "head" of auto-generated Class "JessHead".
Flash compiles with the following warning: Warning: All instances named 'head' will be automatically declared as JessHead in symbols that use Character as their base class. In symbols that are linked to user-defined base classes, instances with the same name must be of the same type. And then the runtime error:TypeError: Error #1034: Type Coercion failed: cannot convert EmilyHead@3a0d1e81 to JessHead. at flash.display::Sprite/constructChildren() at flash.display::Sprite()at Character() I can turn of auto-declare stage instances in the Actionscript 3 panel, but then I have to manually add a public var for all sub-child's, such as the head sprite. But then at least everything works as expected. This is more setup than I'd prefer to do, but everything else about this workflow is very fast & easy. What can I do to sidestep this error, while keeping the same workflow?

View 1 RepliesI have a class Grid which produces a graph paper like grid on in the drawing area. I then have 5 other classes for different shapes to draw with; Line, Polygon, Ellipse, Curve, Arc Now, these 5 classes use an instance of Grid because Grid has a resolution and a scale. Inside Grid I have:
public function set resolution(x:Number):void {
_gap = (modBy10(x) / 10);
_scale = (modBy10(x) / (this.resolution * _scale));
[code]....
I'm just lost for a solution on how to update every instance of my 5 drawing classes when Grid is changed.For instance, Polygon is made up of multiple instances of Line, Line(length, angle) where "length" is in either in, ft, cm, or m. If the user wishes to change the scale from say 10ft per 100px resolution to 20ft per 80px.. Is there an easier way than re-drawing every Line inside Polygon?
I have a TLFTextField created in Flash Professional and I'm attempting to alter it's appearance via code, in Flash Builder.
I want to retain all formatting rules already applied to the TLFTextField unless I specifically change them, however the following code:
var format:TextFormat = textField.getTextFormat();
format.align = TextFormatAlign.RIGHT;
textField.defaultTextFormat = format;
[Code]....
how to alter individual formatting properties on a TLFTextField without affecting those already set?
i have a variable declared in alchemy asm:
asm("var buffer:Vector.<Number> = new Vector.<Number>(100, true);");
i can populate it with data like so:
asm("buffer[%0] = %1;" : : "r"(index) : "r"(value));
what i can't figure out is how to get a reference of that asm "buffer" variable into actionscript.
(i did think of one way... what i did was to throw the "buffer" from alchemy asm, and then catch it in actionscript, but unfortunately it seems to leak a lot of memory).
is there a better alternative to doing this?
note that performance is critical, and using default alchemy marshaling is way too slow.

I have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information.
Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown:
"Access of undefined property currentState."
I am creating a Weapon class for a game and the weapons itself will be the sub classes. The sub classes will hard code some values (such as max ammo and the weapon name).
I trying to access this declared data in the base class constructor, at the moment it's not outputting the values. Is this possible?
I've broken my Weapon class for simplicity:
ActionScript Code:
package
{
import flash.display.MovieClip;
[Code]....
My current workaround is creating a protected method in the base class to trace the information and calling that method in the sub class's constructor, this works fine but this doesn't seem like the most efficient technique?
This is my first custom class and I'm having a few problems. I just want it to draw a line (for now) using variables from Flash. The .as file is attached.

What is the correct syntax to initiate a function in a class similar to constructing an associative array? I have a function that's custom variables is ballooning out and I'd like to label them in the call for sanity sake.
currently:
myClass.myClassFunction("hello world",999,0xff0000);
desired:
myClass.myClassFunction(myText:"hello world",myNumber:999,myColor:0xff0000);
and the class itself for reference:
class com.myClass {
public var myText:String;
public var myNumber:Number;

I have a little problem in my game. I have a var coins:int = 0; on frame one, and I want to access it from frame 2. I'm not using a document class. Is it possible to make some kind of a global variable like in as2 without having to put all my code from the main timelime to a document class?
View 1 RepliesIs it "better" to initialize AS3 class variables in the class constructor? Or can I just initialize them to their default value when I declare them at the top of my class? I ask because when there's a lot of class variables, it appears inefficient to declare them in one place and then initialize them in another when I could easily do both in the same place. It one option is better than the other,
