Forums → Programming Forum → Hittesting multiple movie clips with the same identifier? (AS2)

Yes there should only be one loop(unless you need a "mini" loop that gets removed shortly)

how are you adding your movie clips? If everything is all added on the main timeline I think this might actually work for you

for(var i:int = 0; i < root.numChildren;i++)
{
if(HERO_MC.hitTestObject(root.getChildAt(i)))
{
trace(root.getChildAt(i));
}
}

without looking at your code of course. You will need to determine what movie clip is holding all the children. Maybe you have a hero that you add and a level_MC which contains all the enemies ground/walls whatever. "root" would be changed to level_MC

I'll try that out, thanks

Nope, get the error "Could not load the class or interface 'int""⦠Is int an as3 thing?

Wait, changed int to number no errors but how do I access the properties of the object I hit? Like X Y Alpha etc

look at the trace that shows up when there is collision, it might just say "coin"

at that point you can get use name and make the function to suit

for(var i:int = 0; i < root.numChildren;i++)
{
if(HERO_MC.hitTestObject(root.getChildAt(i)))
{
var object = root.getChildAt(i);
if(object is coin)
{
//coin function
}
if(object is ground)
{
//ground function
}
}
}

Oh, ok, in As2 wouldn't I need to do this though?

var object:MovieClip = getchildstuffblahblahâ¦

Anyways I will try both ways thanks for your help

well kinda, it in itself doesn't need to be declared as movieclip as it already is one. Replace the term "object" with anything you like

var interactiveObject = root.getChildAt(i);
if(interactiveObject is coin)

ah, ok

What the heck am I doing wrong here!?

Here is my code:

onEnterFrame = function() {

for(var i:Number = 0; i < coins.numChildren;i++)
{
if(char.hitTest(coins.getChildAt(i))==true)
{
trace(coins.getChildAt(i));
var object = coins.getChildAt(i);
if(object is coin)
{
coin._x = 100000;
trace("YOU WIN&quot;
}
}
}

}

And I get 2 errors:

Unexpected } encountered.

Expected ).

I have triple checked both and am not finding anything wrong

I think this might be a case of

{ code in here }

and you might have

{ code in here } }

check the full code

The code has no errors now but doesn't work. WTH IS WRONG WITH IT!?

var object:MovieClip = coins.getChildAt(i);

onEnterFrame = function() {

for(var i:Number = 0; i < coins.numChildren;i++)
{
if(char.hitTest(coins.getChildAt(i))==true)
{
trace(coins.getChildAt(i));
trace("YOU WIN&quot;
object = coins.getChildAt(i);
if(object == coin)
{
coin._x = 100000;
trace("YOU WIN&quot;
}
}
}

}

//you havent declaired the variable i
var object:MovieClip = coins.getChildAt(i);

onEnterFrame = function() {

//here is where the variable i is declaired
for(var i:Number = 0; i < coins.numChildren;i++)
{
if(char.hitTest(coins.getChildAt(i))==true)
{
trace(coins.getChildAt(i));
trace("YOU WIN&quot;
object = coins.getChildAt(i);
if(object == coin)
{
coin._x = 100000;
trace("YOU WIN&quot;
}
}
}

}

onEnterFrame = function()
{
for(var i:Number = 0; i < coins.numChildren;i++)
{
trace(coins.getChildAt(i));
}
}

do this first and does it trace the coins?

what is the point of for? why not use if's? is it possible that for is the problem?

i just googled "for loops explained" and found this HERE

basically the for loop runs more times than the if pending the structure

for (counter; condition; action){
statements;
}
