onComplete on chained tweens

[gwalchmei]

Hello,

 

I want to execute a function at the end of a tweens chain.

 

Here is an example of what I did :

var currentTween = null;var prevTween = null;myGroup.forEach(function (obj){    currentTween = game.add.tween(sprite).to({ x: obj.x, y: obj.y }, 100, Phaser.Easing.Linear.None);    if(prevTween){        prevTween.chain(currentTween);    } else {        sprite.movementAnimation = currentTween;    }    prevTween = currentTween;});/* add here the onComplete callback */sprite.movementAnimation.start();

My animation works like a charm.

 

First I tried :

sprite.movementAnimation.onComplete.add(myFunction, this);

=> myFunction executes at the end of the first tween.

 

Then I tried :

sprite.movementAnimation.onChildComplete.add(myFunction, this);

=> myFunction is never called but I have no errors.

 

Then I tried :

sprite.movementAnimation._lastChild.onComplete.add(myFunction, this);

=> I get the error "Uncaught TypeError: Cannot read property 'onComplete' of undefined" (in fact console.log(sprite.movementAnimation._lastChild) returns undefined)

 

 

Could one of you explain me what I did wrong or show me another way to achieve what I want to do ?

 

Thanks.

ok, I've done this, and think you're pretty close

 

this:

sprite.movementAnimation._lastChild.onComplete.add(myFunction, this);

should be

sprite.movementAnimation._lastChild.onComplete.add(this.myFunction, this);

The _lastChild property is undefined (and I can't find it on the API (http://docs.phaser.io/Phaser.Tween.html )

I also like to see _lastChild fixed (and documented) or some similar alternative.  I needed to do this in the game I am developing but had to opt out of a particular enhancement, at least for now.
