 The player can create their own turtle AIs by extending the `TurtleParent` class and overwriting a few key methods. The game is run using discrete step events (at a rate of approximately 30 steps/second), with each turtle defining its actions on a per-step basis. Custom AI submodules (in the form of standalone `.py` files) can be added to the `ai/` directory to import the player's AI into the game. Several example and template subclasses are included in this directory to get the player started. See also the [documentation below](#instructions) for a detailed guide to writing custom AIs. Python students might enjoy competing against each other to see whom can come up with the best AI, while Python instructors might consider running a class tournament to encourage students to learn more about object-oriented programming.
