Project Notes

The cat is trying to touch the grasshopper. The point of this project is to make an algorithm for a computer controlled sprite to make its way through a landscape with barriers. It's not very smart. Scratch moves toward the grasshopper. If he touches a barrier he bounces off at a semi-random angle. To keep him from walking right back into the barrier, he runs away from the grasshopper for a certain amount of time. The amount of time he's in "avoid" mode depends on how many times he bounces off a wall while in avoid mode. This way he doesn't waste a lot of time if he keeps bouncing around between barriers. It's very heuristic. I couldn't think of a reasonable way to try to walk around barriers, since you can't find out the angle of the barrier. Well, you could make the barrier from a bunch of segment sprites and have each one know its angle, but that's not very flexible. I'm interested in your comments and any other algorithms to do this same thing.
