I wrote a simple bot program to test out ai. The bots are not very smart though, they're RND() based ;)
The blue is the player snake, the rest are bots.
Good example of random, though I'm not sure it really qualifies as AI.
If SmileBasic had database capabilities, you could add code to make it track your own drawing, though, store key-points in a database and then have the automated drawing function draw based on the database. Now that would be an AI! ...pretty sure we don't have database capabilities, though.
