ios - How to mask sprites in cocos2d?

Question

I've read Ray Wenderlich's tutorial on sprite masking: http://www.raywenderlich.com/4428/how-to-mask-a-sprite-with-cocos2d-2-0. However, my understanding of openGL is poor, and this tutorial doesn't produce the effect I desire. What I would like to do is to mask one sprite/layer with another, and move the sprite behind the mask to create a "shiny" animation, like so:

Additionally, how could I make the mask dynamic (ex: changing the text string), and how could I make a sprite or layer count its children as part of the mask?

Answer 1

我认为您可以通过动画来做到这一点，将“反射精灵”放在“遮罩精灵”下方，然后将“反射精灵”从左向右移动。

Answer 2

我认为这个 Github 存储库会对你有所帮助。
