How to get targets coordinates (on the fly) ?

[SudoPlz]

I would like to get my target and access its properties (while tweening).

I tried onUpdate func etc, but I can't seem to get the target out of the event.

Se below to understand what im talking about.

 

tileMovement.insert( TweenLite.to(target, 1, {y:-(tileHeight*2), scale:2, ease:Elastic.easeIn, onUpdate: deebreeStart})
for (var x:uint =0 ; x< 3; x++){
deebree = particles.createDeebreeParticlesAt( target.x , target.y );
deebree.start(1);
}

 

 

function deebreeStart(evt:TweenEvent):void {

 trace( evt.target.x);

}

This results on

ArgumentError: Error #1063: Argument count mismatch on Function/deebreeStart(). Expected 1, got 0.

 

 

 

To tell the whole story, I wan't to get some particles to follow a few tiles while they are moving. That why I need to access the tiles properties.

Any suggestions?

Yes, the onUpdate callback is not handled like an as3 native Event. It is simply a function that is being called, not an Event that is being fired.

 

If you use TweenMax, you can use

 

someTweenMaxTween.addEventListener(TweenEvent.UPDATE, deebreeStart);


function deebreeStart(evt:TweenEvent):void {
//the target of a TweenEvent is the tween that fired the event. The target of a tween is the object that is being tweened.
    trace( evt.target.target.x);

}

 

 

 

 

 

Or, using v12 you can now self-reference the tween/timeline in the onCompleteParams, onUpdateParams, onstartParams, onreverseCompleteParams, or onrepeatParams using the special keyword “{self}”. For example:

 

TweenLite.to(mc, 1, {x:100, onUpdate:reportTime, onUpdateParams:["{self}"]});
function reportTime(tween:TweenLite) {
   trace("time: " + tween.time() + ", target: " + tween.target);
}

This works with all callbacks in TweenLite, TweenMax, TimelineLite, and TimelineMax.

One other simple solution for you (which works in any version of TweenLite) is to pass the target using onUpdateParams like:

 

 

tileMovement.insert( TweenLite.to(target, 1, {y:-(tileHeight*2), scale:2, ease:Elastic.easeIn, onUpdate: deebreeStart, onUpdateParams:[target]})

function deebreeStart(mc:DisplayObject):void {
 trace(mc.x);
}
