i am creating a certain amount of instances of a class-object (called Jaar).When i click on one of them, I would like to change a value (isSelected) in all the instances of this class.How can i do this?So far i have this (simplified version) :
ActionScript Code:
package{
import flash.display.*;
[code].....
Exactly this doesn't work but is there a way to do it?
Code:
for ( var i = 0; i < 10; i++ )
{
var ["object"+i]:MyClass = new MyClass();
// would create object1, object2, object 3, object 4, ...
}
basically i want to create ten balls on the stage. I have a balls.as file which uses the drawing api to create a circle within it. also within the balls.as file there is a public variable.[code]how would i go about finding out: if you click one of the balls it traces that balls life.

I'v been toying with this for a few weeks now and I'm trying to find the best way to animate several instances of an object created by a for loop thru an ENTER_FRAME function.When the function runs only 1 of the 3 instances that were created animates.
var balloonArray:Array = new Array();var balloon: hotAirBalloon;var xVel: Number = -3;var yVel: Number = -4;
addEventListener(Event.ENTER_FRAME, startBalloons)
[code]....
I thought this would be simple but for some reason I'm having all kinds of problems. Why won't the for loop create a new c instance each time the loop increments, like it does for sHolder and s? ...And, assuming it is possible to make it do this, how can each instance be given an identifier that can be accessed dynamically, like sHolder and s in the traceSomething function?
Code:
package {
import flash.display.Sprite;

I want to know how to make class instances into listeners and broadcasters, from inside each class. Here is what I am trying specifically... part of the Proj class... (projectiles, as a matter of fact)
Code:
private function listen():Void {
u.register(this);
onUpdate = function(){
step(); // a function I have which makes the projectile move (not shown)
}
}
where "u" is another class, the Updater class with this code...
Code:
class Updater {
// const. --- make this a broadcaster
public function Updater(){

PS: What is the syntax for using AS2 code tags instead of just "[CODE|"?
I'm slightly new to Flash CS3 + AS3 combo, so its more of a lack of practice question. My question stems from the problem described here http:[url].... . Note, its not the same problem, its a new one.The Problem ,So I have multiple library assets (which are on teh stage) and I want to assign similar functionality to all of them.
Attempt 1: So I create the n assets, create a custom class in AS3, link them to Flash CS3 and obviously enough it gives me the error that multiple assets can't be linked to the same class.Obvious enough to understand (well not completely, because from a programmers background it doesn't make sense).
Attempt 2: Same as attempt 1, but instead of linking all the assets to the same class I make the base class the same class, and let the derived class be dynamically created by Flash on compile time.So the linking works, but the problem is, in my base class I have a method which does something (say an tween) on a child of the library asset. So if the assets on the stage/library are called asset1, asset2, asset3 (same name for asset name, class name, id name), each of them has a sub-movieclip called ... say 'foo'. now if I manually wrote a class for each asset, I could do 'this.foo' to play with the sub-movieclip. However since this functionality is in the parent class, I'm unable to do it.
P.S. If you're form a programming/OOP background, its basically a abstract class problem. My Base class knows how to doSomething(), but it needs aSomething, which is defined in the Derived classes. However I found out that AS3 classes don't support virtual(C++ )/abstract (Java) in the true sense of the word (unless I missed some obvious documentation).
Let's say i have a bunch of balls/cells. I'm having trouble figuring out how to make it so that every other ball bounces off of every other ball.
so in short, it's really one instance being able to check all other instances of the same ball class?
I've been hitting dead ends while programming lately all over, and I finally came to the realization all the code I have that is broken is because I don't know how to interact with instances of one class from within another. Here's the gist of what I am trying to do:
if(this.hitTestObject(targetClip)){
trace("hit!");
}
The problem is, if I address a single instance that is on the canvas, I get "access to undefined property targetClip", even though the document class can interact with it fine. If I target the class file of targetClip, I get "Implicit coercion of a value of type Class to an unrelated type flash.display:DisplayObject". It isn't just a problem with hitTest either, I'm having this problem with other actions, so there is some basic syntax I'm failing to comprehend.
[code]My code will:
- loop through the Grid array and place each tile on the stage
- assign RedBall a random Grid coordinate and places it on the stage at that coordinate
I want to be able to click RedBall, which will create a border around the tile beneath RedBall, and create borders around the tiles above, below, to the left and to the right. BUT, I don't want to reference the tiles by their distance in pixels from RedBall or from each other; I want to reference the tiles by their coordinates in the Grid array. So I want to:
- get the coordinates of RedBall
- use those same coodinates to reference the tile at the same coordinates in the Grid array
- use the tile's coordinates to reference the tiles above/below/left/right
- apply a border to all these tiles
What's the best way to reference an instance of a tile? Should I apply a name to each instance as it's created in the loop? like myTile.name = "tile"+i+"_"+j; ? If so, how do you reference that instance later? Just tile1_3 ? Do you have to prepend it with root, or stage, or the class it was originally created in? Do you have to use getChildByName? OR, can you still reference it later without having given it a name?
There's 3 boxes I'm indexing through with a timer. They disappear in sequence. How do I make them reappear?
boxes disappear in sequence 1-3
var pink:Array = ["","boxInstance1","boxInstance2","boxInstance3"];

timer.addEventListener(TimerEvent.TIMER, onTimer);

I'm not to particular about the sequence they disappear and appear, but it need to keep going in a loop.

I'm very new to Adobe Flash CS5.5. Can you create a common instance EG: "Enemy" and then control it like so:
Enemy.x += 1;
So that all instances of Enemy will move forward one pixel each frame? Instead of just one enemy? If this is not possible could I set up some sort of array of enemies like you can in C and try something like:
int EnemyNo = 1;
for(EnemyNo = 1; EnemyNo < 5; EnemyNo++) {
Enemy[EnemyNo].x += 1;
}
Does Flash even support "for" loops?
I have a bunch of movie clips on a layer named s1, s2, s3, .. s16.
I need to add them to an array so that I can select a random number to play.

for(i=0;i=16;i++)
{
sparkle[i] = 's'+i;
}

function generateHex(e:MouseEvent)
{
tileSet.x = tileSize;

- loop through the Grid array and place each tile on the stage

I am trying to create TextField Instances for a crossword puzzle in Flash through a loop and then address them later how do I do this. My Code:[code]
View 12 RepliesSo I know that if I want to create an instance of a movie clip called part01Roads from the library I do this:
Code:
var part01Roads_mc:part01Roads = new part01Roads();
addChild(part01Roads_mc);
part01Roads_mc.x = -22379;
part01Roads_mc.y = 317;
Well I want to take this one step further if it is at all possible. Lets say I have 100 different movie clips labeled in a sequence: part01Roads, part02Roads, part03Roads ..... part100Roads. Instead of rewriting the above code 100 times, can I make a loop to do this?
In the library of the FLa I have a symbol that is exported for actionscript with a class name of 'aClip'.I am placing multiple instances of it on stage as follows:
Code:
for (var i:int = 0; i < 10; i++) {
var myClip:aClip = new aClip();
myClip.x = 0;
myClip.y = 50 + (50 * i);
}
Each myClip will move across the stage at 1 unit per frame. If I only had 1 instance on the stage I would implement as follows:
Code:
//make an enterFrame listener for the stage
this.addEventListener(Event.ENTER_FRAME, moveClip);
//make a function for the listener[code]...
The problem I am having, is getting this to work for the multiple instances generated in the for loop.

however, I realize even tho im looping that addChild method, its still adding sp, so do I add a new naming convention in the loop, or should I be adding these instances to another display object.... this seems like such a simple thing to do yet I cant figure it out, I also want to randomize the x and y, but this first seems to be the issue I need to address.
I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

I have a class CoverPoint extends Pointwith some extra function.except for that ther is no difference. I would like to use the functions of Point with a return value of Point, to calculate those CoverPoints.Can i turn the return value into CoverPoint (since all the vars are the same, there shouldn't be a problem with that, right?), so that it can be stored in my var cP:CoverPoint;

But I want a better way (more efficiently, without checking all the MCs).
I have a number of instances of a library object placed directly onto the stage (I don't want to have the code create them since they have to be positioned and scaled individually) want to be able to find all the instances in actionscript and assign them to an array. How do I do that? I think getDefinitionByName is what I need but I can't figure out how to get it to do that.
