stop tween?

[spires]

Hi

I have a MovieClip that moves to where the mouse was last clicked.
I also want this MovieClip to stop when it comes into contact with another MovieClip. I'm doing this via hitTestObject.

This all works fine, but, I can only get either the X or the Y tween to stop.
I can't get them both to stop?

// Zac Move
stage.addEventListener(MouseEvent.MOUSE_DOWN, MoveZac);

function MoveZac(event:MouseEvent):void
{
	dylan.play();
	if(mouseX > zac.x){
		zac.gotoAndStop("zacRight");
	}else{
		zac.gotoAndStop("zacLeft");		
	}	
   		var zacTweenX:Tween = new Tween(zac, "x", Regular.easeOut, zac.x, mouseX, 1, true); 
    	var zacTweenY:Tween = new Tween(zac, "y", Regular.easeOut, zac.y, mouseY, 1, true);
		
   		var chng:Number = .4 + ((mouseY / stage.stageHeight) * .6); 
    	var sX:Tween = new Tween(zac, "scaleX", Regular.easeOut, zac.scaleX, chng, 1, true); 
    	var sY:Tween = new Tween(zac, "scaleY", Regular.easeOut, zac.scaleY, chng, 1, true); 
				
		zacTweenY.addEventListener(TweenEvent.MOTION_CHANGE, onMotionChange);		
}

// Hit Test
function onMotionChange(e:TweenEvent):void
{
	if (dylan.mcDylanWalkPath!=null) {
		if (zac.mcZacWalkPath.hitTestObject(dylan.mcDylanWalkPath)){
			e.target.stop();
			dylan.stop();
		}
	}
}

As you can see,

zacTweenY.addEventListener(TweenEvent.MOTION_CHANGE, onMotionChange);

is only referencing the Y tween and not the X tween.
How do I pass the zacTweenX variable into the onMotionChange function?


Thanks for your help

ok

I have worked out a way of doing it.
but i'm not to sure if it's the best way to do it:

zacTweenY.addEventListener(TweenEvent.MOTION_CHANGE, onMotionChange);	
zacTweenX.addEventListener(TweenEvent.MOTION_CHANGE, onMotionChange);

This way I'm calling the function twice.
Will this be more processor intensive?
Is there a better way of doing this?

Thanks

The built in Tween class is notoriously hard to work with, is pretty limited, and isn't great performance-wise. Most people use any of the several freely available public classes (TweenLite, tweener, GTween, tweensey) or write their own.

I think the Adobe tween is the only one that limits each tween to a single property.

Use tweener, Its probably the best, in my personal opinion.

ok excellent.

hi

sorry, but where do you download the tweener class?
I've googled it but can't find a site.

Also, is there a tweener tutorial somewhere?

Thanks

i just put "tweener" in google - it's the first result:
