Tween callback being called multiple times

[Meowts]

Six times, to be exact. Here's what I'm doing:

//Chained tweenvar tween = this.game.add.tween(player.player).to({x: this.chosenOne.x, y: this.chosenOne.y}, 1500, Phaser.Easing.Quadratic.InOut, true, 0, 0).to({x: this.chosenSplit.x, y: this.chosenSplit.y}, 1500, Phaser.Easing.Quadratic.InOut, true, 0, 0).to({x: point.x, y: point.y}, 1500, Phaser.Easing.Quadratic.InOut, true, 0, 0);	//Add handler to the last child of the chaintween._lastChild.onComplete.add(this.showError, this);	

this.showError() ends up being called 6 times. Is there a better way of assigning a handler for when the last tween is completed?

Have you tried:

this.game.add.tween(player.player)    .to({x: this.chosenOne.x, y: this.chosenOne.y}, 1500, Phaser.Easing.Quadratic.InOut, true, 0, 0)    .to({x: this.chosenSplit.x, y: this.chosenSplit.y}, 1500, Phaser.Easing.Quadratic.InOut, true, 0, 0)    .to({x: point.x, y: point.y}, 1500, Phaser.Easing.Quadratic.InOut, true, 0, 0)    .onComplete.addOnce(this.showError, this);// notice I used .addOnce and included it in the chain instead of using a private var.

The moment you start adding things to, or manipulating private properties you should be questioning exactly why you had to do this. It's rarely required and/or leads to the desired outcome.

Cool, thanks for that advice! Funny, I had a few different tweens in different situations where I had defined onComplete that way, and it wasn't until I fixed all of them that the handler was being called once. Good indication I was doing it wrong XD

Oh yeah, forgot to mention though (duh), the onComplete handler, though being called once, is being called after the first tween animation.

here is an example on how to chain tweens and make the oncomplete callback (which everyone would expect to be fired onComplete of the LAST tween not the first) be fired at the end of the chain.

var ascent = game.add.tween(body.sprite.scale).to({x:max,y:max}, upTime, Phaser.Easing.Sinusoidal.Out)var descent = game.add.tween(body.sprite.scale).to({x:originalScale,y:originalScale}, downTime, Phaser.Easing.Sinusoidal.In)descent.onComplete.add(function(){    do something });ascent.chain(descent).start();
