Why can't I call start on a tween object twice?
Lets say I have this code:
var mySprite=this.add.sprite('mySprite');
mySprite.alpha=0;
var mySpriteTween=this.add.tween(mySprite);
mySpriteTween.to({alpha:1},1000,'Linear',false,0,0,true);
mySpriteTween.start();
mySpriteTween.start();
When I call start() the second time the tween does not run even though I have yoyo set to true and thus the alpha of mySprite has been tweened back to zero.
Does the Tween Manager clear the TweenData object owned by mySpriteT
Hi, you are setting yoyo tween. Your number of repeats is 0, which means it will run once. As it is yoyo tween it will first tween alpha from 0 to 1 and then yoyo part starts and tweens alpha from 1 back to 0.
In your code, you are calling start twice without any delay or time to finish your 2 seconds (2 x 1000 - there and yoyo back) tween. If you call start on running tween it is ignored (see https://github.com/photonstorm/phaser/blob/master/src/tween/Tween.js#L296)
In case yo
