问题 What would be the best way to do this? I see the CCEaseSineInOut action but it doesn't look like that could be used to do this. I need to move from one side of the screen to the other. The sprite should move in a sine-wave pattern across the screen. 回答1: I always like to have complete control over CCNode motion. I only use CCAction s to do very basic things. While your case sounds simple enough to possibly do with CCAction s, I will show you how to move a CCNode according to any function over

While your case sounds simple enough to possibly do with CCAction s, I will show you how to move a CCNode according to any function over time. You can also change scale, color, opacity, rotation, and even anchor point with the same technique.
