Constraining a Sprite to a Path

[glenbull]

For construction of a game in the style of Pacman, what is a good strategy for constraining a sprite to a path? If someone could point to a good implementation of this in the Snap! games collection, that would be helpful. Thanks in advance for any assistance from some of the avid games developers on the forum.

Use . If that's true, back up a little (so the sprite is no longer touching the wall) and turn 90° one way or the other.

So essentially it would be the equivalent of "Bounce" in a Pong style game. (Thanks!)
