为什么我的Phaser渐变消失了？

Question

我正在尝试创建一个径向渐变，从一个点开始并从那里生长，有点像填充房间的烟雾。我从这个例子开始：

https://phaser.io/examples/v2/bitmapdata/radial-gradient

并且一直在慢慢调整它以满足我的需求。我目前的问题是，当我的补间停止运行时，整个事情就会消失。这就是我所拥有的：

在更新功能中：

    this.radGrad = this.game.make.bitmapData(600, 600);
    this.radGrad.addToWorld();
    this.outerCircle = new Phaser.Circle(200, 200, 0);

    this.smokeTween = this.game.add.tween(this.outerCircle).to( { radius: 300 }, 5000, Phaser.Easing.Sinusoidal.Out, true);
