Are you ready to dive into the world of artificial intelligence and game strategy? With Catanatron, the Settlers of Catan bot simulator, you can test various strategies at scale—running thousands of games per minute! In this guide, I’ll walk you through how to set up Catanatron, implement your bots, and enhance their capabilities.

Getting Started: Installation

First things first, let’s set up your environment for Catanatron. Here’s how to do it step by step:

• Clone the Repository: Open your terminal and execute:

git clone git@github.com:bcollazocatanatron.git

• Change Directory: Navigate into the cloned repository:

cd catanatron

• Create Virtual Environment: Ensure you’re using Python 3.8 or higher:

pip install -r all-requirements.txt

Running Your Simulations

To run your initial simulations, use the command below to set up a game:

catanatron-play --players=R,R,R,W --num=100

This command simulates 100 games with three Random players and one Weighted player.

Designing Your Own Bots

Want to add your personal touch? You can create your own bot by following these simple steps:

• Create a Python File: Name it something like myplayers.py
• Define Your Player: Here’s a quick example:

from catanatron import Player
from catanatron_experimental.cli.cli_players import register_player

@register_player('FOO')
class FooPlayer(Player):
    def decide(self, game, playable_actions):
        # More complex decision-making can replace the return statement below.
        return playable_actions[0]  # Returns the first action as a placeholder.

• Simulate with Your Bot: Finally, run your bot using:

catanatron-play --code=myplayers.py --players=R,R,R,FOO --num=10

Enhancing Your Bot’s Capabilities

To boost your bot’s performance, consider adopting a robust strategy such as Alpha Beta Search. Here’s the idea:

Imagine you’re navigating through a dense forest (the game environment) with multiple paths (strategies). The Alpha Beta algorithm helps you prune unnecessary paths ensuring you only navigate through the best options based on the rewards you can achieve. This way, you arrive at your destination (winning the game) faster and more efficiently.

Advanced Usage: Inspecting Games

If you wish to visually inspect the games for debugging or analysis, use Docker:

docker-compose up

Once it’s up, you can save simulations to a database using:

catanatron-play --players=W,W,W,W --db --num=1

Troubleshooting Tips

If you encounter any challenges while setting up or running Catanatron, here are some tips to help you troubleshoot:

• Ensure that your Python environment is correctly set up with all dependencies.
• Check for typos in your commands and file names.
• If your bot isn’t behaving as expected, revisit its logic and test with simpler actions.
