Simple AI help ?

-----------------------------------

can someone show me an example of a simple code (for BlueJ) that has an AI that has a picture value to it and make it move across the screen from left to right so i can get a base started for making my own AI ?

You need to be more specific.  I assume you have a picture of some enemy or something that you want to move based on your location?  For me to help you with a specific AI I need to know what type of game/program you are making.  A very simply one though:

You have a paint method with your draw function with x and y as variables.  In other methods or your program you'd alter x and y based on what you want it to do and then update with your new x and y variables.  I want write for you any specific code though, that has to be one on your own   :D

The kind of game that we're trying to produce is a Tower Defense... you have guys coming from one end to the other and you set up towers to kill them. i don't want all the work done, but enough information to get me started. our programmer teacher isn't here anymore and we have a supply that doesn't know much about BlueJ

Well the "AI" requires to know the shortest path from the spawn point to the exit point, and it follows that path on the screen. Look into the A* (A-star) algorithm

I don't really know Java so I can't give you any code. However, couldn't just use waypoints and advance the unit to the next waypoint and then repeat? I would think that would work, unless of course the assignment is not so much the game as the pathfinding.

Not if there's a defense tower build in between the waypoints.
