As previewed a little while ago, I’d like to introduce Botswana:
Each turn, the engine sends the current state of the world to each bot. The bot can then give the engine its command — to move forward, move backward, turn left, turn right, or fire. Last bot standing wins. We’ve gone with an intentionally simple rule system for now, but we’ve got some fun plans for future improvements.
The code’s open source and is on Github.
