Alpha Tween not working as expected

[jaymeh]

Hi,

I am currently having an issue where my alpha tween on my game isn't working as I expected. I set the tween to happen over 5 seconds however it seems to only take a fraction of the time and ignores the time. Here is my code:

var box = this.game.add.graphics(0,0);
box.alpha = 0.1;

box.moveTo(0, 0);

box.beginFill(0x000000);
box.drawRect(borderSide, borderTop, (this.game.world.width - borderSide * 2), this.game.world.height);
box.endFill();

var fadeTween = this.game.add.tween(box).to({ alpha: 1 }, 5000, "Linear", true);
fadeTween.onComplete.add(this._end_game, this);

You can see my video attached below for an example of this in action.

Thanks,
Jamie

By itself this code is working. The problem must be somewhere else in your code
