I have an idea, if not already done (although I can't do it myself obviously lol).

Is there anyone here who could write a sample game (with source) that displays how to do different AI?

Maybe just some basic stuff like having a sprite follow a basic one way or the other path, to sprites that can find the shortest route to a location.

I dunno really, but an app with source that shows some basic and different kinds of basic AI would be a great help, or atleast I think so.
