ActionScript 3.0 :: Hit Testing Objects In Array
Nov 25, 2011
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 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 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?

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.

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;

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?

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")]

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 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 .

I am wanting to get an array of objects from a get statement in a class.Now I get this to work so i am just checking if this is the best way to do it.
Over 3 classes
//class3 public function get xVal():int { return img1.x; } // END GET _myProperty
//class2 public function get getEnemy():Array { return myEnemyList; } // END GET _myProperty
/class1- calling class var enemyItem:Array = [];
myEnemy.moveEnemy(); enemyItem=myEnemy.getEnemy;

I have is a simple game and when the player picks up 10 objects I would like an enemy to spawn and start chasing the player (the player is attatched to the mouse), after another 10 objects another enemy spawns and so on. This keeps going until any one of the enemies chasing "hits" the player, and then I would like all the enemies that are on the screen to travel off screen at the same location, ready to start over again.
I'm using tweener generally in the game so far for movement of things.I understand I'll need to use an array to create more duplicates of my enemy movieclip? And push one every time 10 objects are picked up.What I can't do is the code to hitest any one of the spawned enemies, I think only one perhaps-the last or first created is ever affected. I've seen others with a similar problem but not quite the same so I haven't found a solution. I'm sure its very simple.

Is it possible to put objects that get the same EventListener in an array so instead of saying
object1.addEventListener(MouseEvent.MOUSE_DOWN, functionName);
object2.addEventListener(MouseEvent.MOUSE_DOWN, functionName);
I can say
allObjects.addEventListener(MouseEvent.MOUSE_DOWN, functionName);

I've successfully access a web service in as3 and pulled the xml from it into a large array of objects
ie
Code:
array
object
array
[Code].....
This has to be accessed at a later point by the UI in order to build itself. I can't figure out how to create a loop or method or whatever to access this array.
I need several ways of accessing it, so maybe I'm thinking of a method called accessSpecificItem(propertyName:String); <- to set up each UI item traceOutAllItems(arrayName:Array); <- for testing countNumberOfItems(arrayName:Array); <- for the UI to figure out how many items it needs to build

I have got an array of objects, each with properties, plus those objects have sub objects.
Example
Code:
Array[0]
Object.id = 0
Object.name = fish
Object.Array[0]
object.id = 0
object.variety = red tetra
[Code] .....
So now it will go through every item in the array and work filterArray on it, but where to proceed from here?

I have a utility function:
function removeFromArray(item:Object, arr:Array):Object {
for(var i:uint = 0; i < arr.length; i++) {
if(item == arr
[Code]....
This function searches through an array and sees if an item exists in it, if it does, it removes it and returns a reference to that item.
This works fine for most things. But I just ran into a problem where I need to remove an array from an array.
so my array looks like this [ [item1a, item1b], [item2a, item2b] ]; and i need to remove [item1a, item1b] from it. But passing in the the array to remove and the full array to remove it from does not work because i guess of the casting to an object in the parameters list. Can the functionality i want be used? if so how?

The problem is the class does not convert it to array if there is only 1 node. I tried to modify it without success.

var s:SimpleXMLDecoder = new SimpleXMLDecoder(true);
