ActionScript 3.0 :: HitTest Between The 2 Arrays?
Sep 4, 2011
i have 2 arrays containing object1 and object2 .
ArrayObject1 type are moving
ArrayObject2 type are stationery
When there is a hitTest between the 2 arrays, Object2 gets the same vx,vy as Object1 and they start moving together.(I need to keep a track of which instance of Object1 is in contact with which instance of Object2).When lets say a BulletObj hitTest Object1, then Object1 is removed from stage (array is spliced) and Object2 should stop moving.

Basically what I'm looking to do is hitTest bullets inside an array (spawn via addChild -> pushed into an array) with another array containing ships (spawn via addChild -> pushed into an array as well).At the moment I have:
function moveEnemyLarge():void{
var target2:EnemyLarge;
for(var i2:int=0;i2<enemyShipArray.length;i2++){
[code]....
.. and a near identical function for the bullets (using variables: i, target).What is the easiest way for me to hitTest the objects within my bullet array with the objects in my ship array. Putting "target" in the PLACEHOLDER slot doesn't work, and from what I've seen some people will shove the one for() inside of the other.

[Code]...
NOTE: The following text is my problem and observations, if you afraid to read it all, my problem is easily guessable within the code go ahead and crack at it without my explanation :-p I'm having some trouble with using hitTest(); with movieclips within arrays. I wanted to build a function that checks the hitTest of Movieclips in arrays because the array is dynamic and it would run more efficient and faster this way.
As you may notice it doesn't check just the movieClip in the array, but a movieclip 2 scopes within it. I feel that this is my problem. I noticed in my debugger that that mc doesn't show up, but i put an onLoad event on it to trace its existence when loaded and it shows up fine. I wonder what I'm doing wrong.

i just would like to know how to create an "hitTest" script inside a movieclip that is actually part of that hitTest code?I mean... I have mc A, and mc B. and the current hitTest code im using (that is on the timeline) makes mc A, destroy mc B when collide with it... but there are many mc B on the stage (with the same instance name) so, when mc A collide with one mc B, it destroys ALL mc's B... but i want it to destroy only the mc B that he collides, not all the others... maybe an hitTest script inside a movieclip B would work (somethig like "if MC A hitTest ME = i die" (not all the others)).

I am running into some trouble adding an array into another array to create a multi-dimensional array.The code appears as below:
var slideDataArray:Array = new Array();
var slideShowDataArray:Array = new Array();
slideDataArray[0] = xmlData.SlideShowParameters.SlideShowImagesDirectory;[code]........
I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.

I've got a bit that loads a big chunk of xml data about products.I push product info into an array(e.g. productArray), then add that array to another array (e.g. allProductsArray)How do I sort those arrays? For instance, if I want to sort the allProductsArray based on the info in productArray[0]?Alternatively, would something other tha an array of arrays be a better route?This loader loads the same sort of info for many different clients, so the bit to sort on will change.

I'm trying to write a function where I can specify any amount of array, and the return value will be an array containing the contents of all of the specified arrays.I've done this, but it seems like a really slow and ugly way of doing it:
var ar1:Array = [1,2,3,4,5,6,7,8,9];
var ar2:Array = ['a','b','c','d','e','f','g','h'];
function merge(...multi):Array[code].....
Is there an inbuilt and more efficient / nice way of achieving this? The result does not need to be in the same order as the input - completely unsorted is fine.

A little explanation: Im making a random arranging number Array. So instead of using a loop and assigning 0 to first array element, 1 to second, etc.I need to make it totally random but without repeating any numbers. To do that I made a second Array that will have the same number of children to serve as a reference.Each of them will be an Object with a property "num" , wich will be its actual number, and a property "called" wich defaults to false.Like this:
ActionScript Code:
for(var i:int=0;i<vQuantity;i++){
ranArray.push( new Object() );

I've had a problem for awhile that was really odd. After some intense debugging, I realized the problem lied in setting an array equal to another array.[code] When setting one array equal to another, the values aren't copied over, but a reference to that memory is stored. So no matter which variable you change, they are both references to the same memory and thus both will reflect the changes.With other data types, this doesn't happen.I could fix it by looping through t1 and using push() to add each index from t1 into t2, but that seems a little messy.

correct syntax for pushing variables to arrays within arrays? I have searched many threads but found nothing that exactly answers my query.I have a class (Brigade) which amongst other variables contains an array (BrigadeUnits) This is the third element.. My Brigades are stored in an array called AllBrigades. I now need to fill the BrigadeUnits array with objects of my Units class.The hierarchy I want to create is as follows:
AllBrigades (array of Brigades)
Brigade (object)
BrigadeUnits (array within Brigade object)
Unit (Object to be stored in BrigadeUnits array)
I have tried various approaches including the following, assuming that I am addressing the first Brigade in the array:
AllBrigades [0] [2].push (MyUnit);
But when I trace this I just get undefined.

I have a movie clip called frog who moves along the screen, I want him to jump when he hits any other movie clips. I can make him do so with the code below, the problem is that if I write the same function for the other movie clips it doesnt work, it still works on the first one but none others. I have tried attaching an onCilpEvent on both the frog and on all the other movie cilps so no avail.
function hitBaby(){
if(_root.babyWord.hitTest(_root.frog)){
_root.frog.gotoAndPlay("frogB");}else{ _root.frog.gotoAndPlay("frogA");}

i'm trying to build this simple game for school: you've got a catapult which launches a "bullet" and you will have to aim it to hit a certain point. Now the whole catapult part and shooting the "bullet" works, but now it has to respond when it hits something, and that's where i'm stuck.

I am trying to create a game. My game is birds eye view game and I am trying to get it so my character (instance name hero_mc )can't pass through the buildings(instance name block_mc). I have been looking at tutorials on the web and most of them cover it so that a text appears if you hit the object whereas I want it so my character can't pass through or well is "push back", the one tutorial I found doesn't want to work for me, but it's not giving me any errors so I really don't know what is wrong with it.
Actionscript Code:
hero_mc.addEventListener(Event.ENTER_FRAME, enter_frame); function enter_frame(event:Event):void{if (hero_mc.hitTestObject(block_mc)) { trace("hero _mc is next to block_mc") } else { hero_mc.y += 10 hero_mc.x += 10 } }
My character still passes through the block objects.

I have this thing where orbs are supposed to stick together, so I put them all in an arrayand told them to stick together when they encounter another member of that array.However, they only stick in groups of up to four, and then the orbs begin to overlap and such.

I am working on a game that involves a play head (called playHead) moving along the screen and when it encounters various movie clips it triggers a sound to be played. It is all going well except that the sound seems to want to play more than once, so there is a staggered wierd sound. Is is possible to make the sound only play once and also it needs to play until the the sound has finished. (the sounds are all very short).Here is the code:
onClipEvent(enterFrame){ if (this.hitTest(_root.playHead)){ _root.sound15.stop(); _root.sound15.attachSound("over"); _root.sound15.start(); } }

I have a playhead that moves across the screen and when it hitTests a movie clip it plays a sound. all is working fine except that it will only work the first time it is played. The playhead is controlled by a button. I am working in Actionscrpt2. Here is the code on the movieclip:
onClipEvent(enterFrame)[code]....
In the begining I was having trouble because the hitTest was playing the sound over and over but the above code sorted that out. I think that the new problem was created by fixing the old one.

These codes are in the draggable MC: fish1_drag this is my code:
onClipEvent (enterFrame) { this.onPress = function() { startDrag(this); };
_root.UI1_mc.UI1_mc2.inv_mc.ISpace1.onEnterFrame = function() { if (this.hitTest(fish1_drag)) { stopDrag(); } else { } };}
I keep jumbling it up so that one thing works but the other doesnt. But basicly I need it so that when I drag fish1_drag (instance name) over ISpace1 (which is within many MCs : _root.UI1_mc.UI1_mc2.inv_mc.ISpace1 but opens up so you can drag it over it) for it the drop on the ISpace1.
I have another MC in the library and il get that the attach to the ISpace1 but what im finding difficult is just being able to drag the fish1_drag over the ISpace1 and releasing.
Here is some other reandom code that I have in a comment on my AC panel:
/*
this.onRelease = function() { stopDrag(); _root.UI1_mc.UI1_mc2.inv_mc.ISpace1.attachMovie("fish1_mc","attached1 ",this.getNextHighestDepth()); _root.invCount += 1; updateAfterEvent(); // I probly dont need this updateAfterEvent. but its there anyway. };

I'm trying to make it so that when a movieclip (box) touches another movieclip (exit), it goes to frame 2.I've made it so that (box) moves with the arrow keys and doesn't go pat the barriers (boulders) using this:
x.onEnterFrame = function()
if (Key.isDown(Key.RIGHT)) {box._x += 5;}
if (Key.isDown(Key.LEFT)) {box._x -= 5;}

_root["zombie"+i].onEnterFrame = function() {
if(this.hitTest(this)){
trace("hit!");
}
}
This does not work, it traces hit! even if none of the movieclips are touching. dont know how else I can do this.

I'm trying to use hitTest so that if any images overlap they will be replaced on the canvass.
ActionScript Code:
function imgSeed(){
for(i=0; i<5; i++){[code]....
although this works, It checks against itself, so it always true at least once, how can I tell it not to check against itself?

Im making a simple game with destructable terrain. Therefore i use a bitmap for the ground and a movieClip for the player. When the ground is a bitmap i cant use regular hitTestPoint because of the bitmaps transparent pixels. So i looking i the livedocs for the bitmapData.hitTest but i rly dont understand all the parameters.So my question is. How can i reproduce this with bitmapData.hitTest?
ActionScript Code:
if(ground.hitTestPoint(player.x, player.y, true)) {
