Hello,

To keep it short, I want to scale a Container using a tween, this has to repeat 2 times and do a callback on each repeat. But having to scale the X and Y seperately fires the callback function twice, is there any way how to prevent this?

This is what I use:  
this.tweens.add({  
targets: this,  
scaleX: 1.2,  
scaleY: 1.2,  
hold: 500,  
duration: 500,  
ease: ‘Back.easeInOut’,  
repeat: 2,  
onRepeat: function() { console.log(‘hit’); },  
});

I also tried to set a temporary variable, set it to 1 and tween that variable and use an onUpdate: function { this.setScale(variable); }. It works, but it’s not really nice.

TLDR: How to scale an object using 1 property in a tween? or How to prevent multiple callbacks from multiple properties in a tween using the onRepeat callback?

Try using `loop` and `onLoop` instead.
