AICA Game Library Fork

This package is a fork of the AICA Game Library for the Game AI Competition Platform of the AI Club Aachen. It contains the shared base interfaces and the Tic-Tac-Toe implementation only. It is designed to be easy to use. Simply instantiate the Agent class and begin!

Installation

You can install the package via pip:

pip install aica-gamelib-fork

Creating an Agent

To create a game AI agent, you need to create a class that inherits from gamelib.GAME.agent.Agent. GAME is replaced by the relevant game. In this fork, the available game is tictactoe. You must implement two methods:

1. initialize(self, agent_init_data): Setup your agent (e.g., store your player ID).
2. get_move(self, game_state): Analyze the game state and return a Move object.

Game Concepts

GameState

The GameState object passed to get_move is defined in gamelib.GAME.gamestate.

Move

The Move object returned by get_move is defined in gamelib.GAME.move.

Example in TicTacToe

Here is a simple example of a tictactoe agent that selects the first available cell on the board.

from typing import override

from gamelib.tictactoe import Agent, GameState, Move

class MyTicTacToeAgent(Agent):
    @override
    def initialize(self, agent_init_data: dict) -> None:
        """
        Called once at the start of the game.
        agent_init_data contains 'player_id' (0 or 1).
        """
        self.player_id = agent_init_data["player_id"]

    @override
    def get_move(self, game_state: GameState) -> Move:
        """
        Called every turn. Returns the move you want to make.
        """
        # The board is a flat list of 9 integers
        # -1: Empty, 0: Player 0, 1: Player 1
        for position in range(9):
            if game_state.board[position] == -1:
                return Move(player=self.player_id, position=position)
        
        raise ValueError("No valid moves available.")

if __name__ == "__main__":
    # Instantiate and start the agent (run by the platform)
    agent = MyTicTacToeAgent()
    agent.start()

You can import this example agent right away with:

from gamelib.tictactoe.examples import TicTacToeAgent

Running Your Agent

The agent uses standard input/output (stdin/stdout) to communicate with the game engine, when running on the platform. This is handled automatically as long as your agent is a subclass of gamelib.GAME.agent.Agentand properly started in the __main__ block.

To test locally, you can use the DevRunner provided in the gamelib.GAME.dev_runner module:

from gamelib.tictactoe import DevRunner

runner = DevRunner()
agent1 = TicTacToeAgent()
agent2 = TicTacToeAgent()
runner.add_agent(agent1)
runner.add_agent(agent2)
runner.start()
