How to simply tween to and from original position once

[Shaun Michael K. Stone]

I see we have type Ping pong as a type of tween. Problem is it loops over and over.

I just want to tween an object to a higher scale, and then return to 1 once:

FlxTween.tween(object.scale, {

x: 1.2,

y: 1.2

}, 0.2, {

ease: FlxEase.elasticInOut,

type: FlxTween.PINGPONG,

complete: function(tween:FlxTween):Void {

tween.cancel();

}

});

When I call cancel, it stops when it reaches a scale of 1.2 instead of when it has returned back to 1 like the ping pong type should do.

Thanks.

Try using the FlxTween.executions field, which tells you how many times the PingPong tween has looped.

I'm not sure if this is a release feature, as I am using the dev branch.

FlxTween.tween(object.scale, {
 x: 1.2,
 y: 1.2
}, 0.2, {
 ease: FlxEase.elasticInOut,
 type: FlxTween.PINGPONG,
 complete: function(tween:FlxTween):Void {

    if(tween.executions==2) {
     tween.cancel();
    }
 }
});

That is exactly what I need! Thankfully available on master. Cheers!

If you're on the dev branch, you can use Tween chaining as well, is case you'd want to have different onComplete functions when the tweens goes back and forth:

FlxTween.tween(this, {y: y - 4}, 0.05, {onComplete: createItem}})
 .wait(0.05)
 .then(FlxTween.tween(this, {y: y + 4}, 0.05, {onComplete: empty}));

That is good to know, I am not on the dev branch, but will move over in my next project and take note of this. Thank you!
