global hittest for all objects

[piratesage]

I have 5 movieclips placed on the stage, all in the same spot. I'm trying to make this hittest code have them all bump off eachother - so they never touch. when you click an object + drag it, I want it to push the other clips away.

It halfway works.. but only certain clips push others away. It seems like clips higher in the index don't get pushed away by lower ones, or visa-versa.

How can I get around that? Whatever clip is selected needs to always push the others away.

Here's the code.



import caurina.transitions.Tweener;

var i:int = 0;
var j:int = 0;

function bumper(e:Event) {
for (i=0; i<numChildren; i++) {
for (j=i+1; j<numChildren; j++) {
if (getChildAt(j).hitTestObject(getChildAt(i))) {
Tweener.addTween(getChildAt(i), {x:Math.random()*stage.stageWidth, y:Math.random()*stage.stageHeight, time:1, transition:"easeOutElastic"});
}
}
}
}

stage.addEventListener(Event.ENTER_FRAME, bumper);

for (i=0; i<numChildren; i++) {
getChildAt(i).addEventListener(MouseEvent.CLICK, dr);
}

function dr(e) {
e.currentTarget.startDrag();
}

you have to rest the var for your second for loop every time otherwise j will = numChildren for every pass after the fist

so...

function bumper(e:Event) {
for (i=0; i<numChildren; i++) {
j = 0;
for (j=i+1; j<numChildren; j++) {

hmm - you sure? that didn't seem to do anything.

oh and take this out
j=i+1

function bumper(e:Event) {
for (i=0; i<numChildren; i++) {
j = 0;
for (j; j<numChildren; j++) {

**edit**

also if you want to optimize your script a little it would be best to store numChildren in an int var, like:

var nc:int = numChildren

that way your not checking all the stages kids twice and on each iteration, ya dig?

[piratesage]

yeah, that makes sense. thanks!

It's still not working, though. The change to the loop that you suggested just made everything go haywire. I added this stuff in, and now both object that collide move.


function bumper(e:Event) {
for (i=0; i<numChildren; i++) {
targetA = getChildAt(i);
j=0;
for (j; j<numChildren; j++) {
targetB = getChildAt(j);
if (targetA !== targetB) {
if (targetB.hitTestObject(targetA)) {
Tweener.addTween(targetA, {x:stage.stageWidth*Math.random(), y:stage.stageHeight*Math.random(), time:1});
trace(targetA.name);
}
}
}
}
}

for (i=0; i<numChildren; i++) {
j = 0;
for (j; j<numChildren; j++) {

oh, so only one object is to move, may bad, let me think about this at lunch and i'll get back to you

***edit***

you could trying assigning a property to the item clicked, you know like, mc._isHeld = true; on click then mc._isHeld = false on release, and just check your mc._ifHeld before you continue with the tween, hope that fixes it...

[piratesage]

thanks for the help. this has been driving me crazy! it seems pretty simple, but i'm not sure what's up. i'm just re-aquanting myself with actionscript after some time away from it.

[GrndMasterFlash]

i re-posted so you would come back and check my last edit

[GrndMasterFlash]

hey piratesage is it working now?

[piratesage]

Sort of.

I had it working for when it was clicked, but after adding some other code, it got a little more complex and I'm back at square 1.

I'm going to try a few more things and post back soon!

[piratesage]

Got it.

function drag(e:Event) {
e.currentTarget.startDrag();
