Moving sprites in a pattern, looking for ideas

I’m working on a classic video game type game. I wan to have aliens move in patterns across the screen, think of Galag or similar games.

Seems there are two routes. Frame type loop, with an algorithm. Or, use a series of transitions. Seems the first is more complex to program. The second seems less elegant.

I did a test using transitions. This seems to work, but requires sprites keep track of their transitions. If a sprite is destroyed you need to cancel all of the transitions assigned to it.

I’m open to thoughts and discussion, I’d like to hear what you think. [import]uid: 98652 topic_id: 25690 reply_id: 325690[/import]
