ActionScript 3.0 :: Flash - Testing An Array Of Objects Against Each Other?
Jan 24, 2011
I have a new flash with several objects(classes) created in as3.They are called Ball1,Ball2,Ball3 and are of type Ball.I wish to be able to insert them into an array and have the array loop test them all against each other like eg. array[i].interact(array[i+1]) and so forthAdditional things I'ld like are:Making sure an object isnt tested against itself,removing objects from an array.sorting the array(if neccessary).adding new objects to the array

I'm having a serious problem with looping through an array. I'm trying to hitTestObject every MC in an array against every other MC in that array.The issue is that in my hitTestObject statement, if obviously looks at only 2 elements at a time.When 2 MC's touch, I set a property called "Touching" to true.The problem is these are moving MCs and at any given time only 2 out of 3 are touching.So what's happening is:The loop runs once testing Array[0] and Array[1].Say those are touching.It sets their "Touching" properties to true(thats what I want).THEN, it runs again testing Array[1] and Array[2], and finds that they are NOT overlapping.It this process it sets both of their "Touching" properties to false, EVEN THOUGH one of them may be overlapping a different array object.I want to individual set the "Touching" property for each array object.Right now these properties are getting overwritten even though 2 out of 3 objects are actually overlapping.[code]

I am making a simulation that involves particles dynamically added to the stage (lots of circles). When these circles collide (which are actually movieclips) they need to rebound (momentum switched). I have no problem with the physics but do not know how to efficiently check for collisions. It boils down to being able to 1) Check if a particle is colliding and 2) Getting which other particle (object) is involved in the collision?
I would ideally like particles to be able to check for their own collisions and adjust their own momentum, not just some meaty Render() function running on every frame. How could this be done?

I'm trying to create a sort of tree diagram such that, if you click on one of the circles, its child circles spread outward with some degree of randomness from the original circle, connected by lines. I have this working, but now what I want to do is make sure that none of the circles collide with each other and none of the lines criss cross. You can see the screenshot for what is currently happening. My code is below. How do I change this code so that it checks for collisions and avoids them? I've read up on flash's hitTestObject command, but that only works in the context one object to another. I want to test for one object contacting any display object.
import com.greensock.TweenMax;
var sw = stage.stageWidth;
var sh = stage.stageHeight;

Is there a method for testing when a shared object has finished loading?because as you can see i have a considerable amount of variables to load, and they don't always load in time.causing many glitches.
ActionScript Code:
wep=saves.data.wep;
backupwep=saves.data.backupwep;

I'm writing a general physics engine and I've come across the problem I've always had with flash. So far all my hittests in my physics engine have been calculated by using x/y coordinates and the 2 objects dimensions. This has worked fine for the objects so far because they have been very square-ish and do not rotated. How ever now I am trying to detect if 2 rotated objects are hitting. How can I do this ? I would really like to avoid using any .hitTest() functions.

Is this the correct, most efficient way to recycle objects when creating an array of objects?
package com {
public class CreateList extends MovieClip {
//this is the object I will be recycling
private var newProperty:PropertyRow;
//this is the array I will use to reference the objects

I use this pattern to test for undefined and null values in ActionScript/Flex :
if(obj) {
execute()
}
Unfortunately, a ReferenceError is always thrown when I use the pattern to test for child objects :
if(obj.child) {
execute()
}
ReferenceError: Error #1069: Property child not found on obj and there is no default value.Why does testing for child objects with if statements throw a ReferenceError?

iSo let's say I have three different arrays of objects, and I want to combine them into one sorted array. I want the order to be such that the items from each array are evenly distributed throughout the sorted array.
If there were 3 xItems, 3 yItems, and 3 zItems, the sorted array would have this order: x, y, z, x, y, z, x, y, z
HOWEVER, even if the arrays are differing lengths, I still need to make them alternate as much as possible. If there were 6 xItems, 4 yItems, and 2 zItems, the sorted array should have this order: x, y, x, y, x, z, x, y, x, y, x, z

I basically need to scale an object up when the user rollsover the button which I have created dynamically already and I need to make sure the object is fully scaled up before I can allow the user to scale it back down again.Ive tried putting 2 tweens (x and yscale) into a function but not sure how to check if the tweens have finished. Im assuming if I check the function is complete it wont take into consideration the tweens may still be running.

I have an array of temporary objects created in a for loop. The objects are of type class "Tile", a class I created. However, it appears that whenever I create a lot of tiles in the for loop, the program slows down indefinitely.
While the array is whiped at a later trigger point, I am thinking that perhaps these Tile objects are not being erased from memory. They are being created on the fly in a for loop, and the array is being reset to "array = []".
Are the objects still in memory or are they cleaned up when the array is set to []?

I have a service which returns an Array of ObjectProxy objects. I would like to cast this to a custom object (a value object) and create an ArrayCollection. How can I do this?ited:I am using Django and PyAMF for the backend. I had to write a custom SQL query and I am wrapping the resulting records in ObjectProxy and sending the whole result as an ArrayCollection.Here is my client side code:
[ArrayElementType("SessionVO")]

I have an array wich is filled with platforms that are supposed to move.
var MovingPlatformArray:Array = new Array();
for (var c:int = numChildren - 1; c >= 0; c--){
var child3:DisplayObject = getChildAt(c);
if (child3.name == "movingplatform"){
MovingPlatformArray.push(child3);
[Code]...
Right now I have 2 moving platforms in this array. But only one moves up and down. But they both register a touch with the birdie.

This should hopefully just be a quickie. I'm slowly starting to learn Flash and Actionscript and right now I'm a bit more stuck than usual. I have an array, "container", to which new movieclips are added by clicking a button. When they are added they are given a name, "pic" + i, and are added at the corresponding index "i". Now, what if I want to change the position of a certain movieclip in the array or alter its alpha value? I tried something like:

I found a good class to convert XML to Array of Objects just like SimpleXMLSecoder do in flex.The problem is the class does not convert it to array if there is only 1 node. I tried to modify it without success.
PHP Code:[code]....The above code returns length if I use the commented list. I want to create 0 index Array if there is one element only.

I worked again on a new Project and stumbled while trying Arrays. I have two cubes(cube_mc, cube2_mc) in my scene.
My code:
var gy:Number = 0;
var gravity:Number = .2
var moving:Array = new Array(cube_mc, cube2_mc);
this.addEventListener(Event.ENTER_FRAME, gravityFUNC);
function gravityFUNC(event:Event):void{
gy+=gravity;
moving.y+=gy;
};
I was trying to put both cubes into the array, and then affecting the whole Array with gravity. When I test it nothing happens, and it shows no errors.

ive come across this method 'as' and I dont get it.I am following a tut, and i have an array with my objects stored in it(for reference to control these sprites).They are instantiations of my sprite class 'Ball.as'
Code:
for(i=0;i<3;i++){
var myMCs:Ball = myMCs[i] as Ball;
}
when I remove it - flash doesnt seem to mind its absence.

I have declared an Array as a new Array(); I would like to push objects into that array but have a text field read back the array minus the commas that are pushed by user interaction (from numbered buttons).
For example, if the user pushes button 1 then button 4 then button 8 I would like the array to read in the text field 148 instead of 1,4,8 .

Flash CS5.5 crashes when testing this movie using CTRL-ENTER a few times. Sometimes, a message warning that the Java Virtual Machine is running out of memory appears. I would like to know whether it is the FLA or my Flash installation that is corrupt.

I recently finally moved across to my Mac for all of my development work. The main problem I have come across is not being able to test any of my work in a SCORM test suite. The one I have on my PC is the ADL test suite which does not appear to be compatible with the mac, so does anyone know of a suite that is?
