tween yoyo not working

[Geoeo]

Hello,

 

the following lines of code do not result in the tween being "yoyoed".

Am I missing something very simple?? :/

 

if(this.game.input.keyboard.isDown(Phaser.Keyboard.SPACEBAR)){this.game.add.tween(this.player.scale).to({x : 2.0, y : 2.0},300,Phaser.Easing.Linear.None,true,0,0,true);//                .to({x : 1.0, y : 1.0},300,Phaser.Easing.Linear.None,true,0,0,true)//                .start();        }

The commented out code is my dirty fix, but ideally I want to do it in one line.

 

 

Thanks

Look at this example: http://examples.phaser.io/_site/view_full.html?d=tweens&f=yoyo.js&t=yoyo

 game.add.tween(sprite).to( { alpha: 1 }, 2000, Phaser.Easing.Linear.None, true, 0, 1000, true);

Ok, so the yoyo effect only works when the penultimate arguments is non-zero. hmmm...

 

This works : 

this.game.add.tween(this.player.scale).to({x : 2.0, y : 2.0},300,Phaser.Easing.Linear.None,true,0,1,true);

Thanks Pedro!

 

Edit: Successive triggers of this tween i.e. hitting the space tab will make the sprite grow permanently. I.e. it does not revert back to scale 1.0.

Anybody have an idea why?

I suppose the tweenings are cumulative, so successive triggers adds a new tween. It should be added only once.

The solution is to add the tween receiving the object's reference and then start the tween any time you want

// take a look at the autoStart = false parametervar myTween = this.game.add.tween(this.player.scale).to({x : 2.0, y : 2.0},300,Phaser.Easing.Linear.None,false,0,1,true);myTween.start();
