Tetris bot engine

Project description

sirtetris

sirtetris is an engine for Tetris bots. Its core is the gamestate module which is engageable with the following things:

  • capture:
    • Sets the size of the game field (number of horizontal and vertical tiles), size of the tiles, where to find the next tetromino (piece),
    • analyze a source (e.g. an image) to provide methods to check whether a tile is occupied or not, whether the spawn field is occupied or not, and to get the tiles within a given dimension, and
    • sets the next tetromino.
  • controller:
    • Defines the command button (A, B, LEFT, RIGHT, UP, DOWN) and action (tap, press, release), and
    • provides a method to send the command to something (e.g. an emulator or a piece of hardware connected to a console).
  • bot:
    • Receives the gamestate and can return commands to the game.

The overall game loop is as follows:

  • The connected capturing method updates the game with a gamestate model,
  • the game invokes the connected bot with the gamestate,
  • the bot has arbitrary intelligence to decide which commands to return to the game,
  • the game sends those commands to the connected controller,
  • the controller executes the commands on its destination (emulator, console, ...).

Getting started

The package comes with a sandbox.py which connects to a Fceux emulator for capturing and controlling, and lets a bot yield random commands:

from sirtetris.gamestate.models import Game
from sirtetris.capture.FceuxStreamCapture import FceuxStreamCapture
from sirtetris.controller.WindowController import WindowController
from sirtetris.bot.Bot import RandomBot

capture = FceuxStreamCapture()
controller = WindowController()
bot = RandomBot()

game = Game(silent=True)
game.connect(capture)
game.connect(controller)
game.connect(bot)
game.capture.listen()

To connect a custom bot simply create a class extending sirtetris.bot.Bot which returns a list of sirtetris.controller.Controller.Commands.

Note: The controller sirtetris.controller.WindowController only works on Linux and needs to be executed as sudo to generate keyboard commands. Feel free to pull-request more controllers!

Note: sirtetris.capture.FceuxStreamCapture only works on Linux. Feel free to pull-request more capturing methods!
