Welcome to the exciting world of reinforcement learning with the Gym-Mupen64Plus environment! This project serves as a bridge, allowing your AI agents to traverse through classic Nintendo 64 games using the OpenAI Gym framework. In this article, we will guide you step-by-step through the setup process, highlight some troubleshooting tips, and explain the code in a relatable manner.

Overview

The Gym-Mupen64Plus project is an environment wrapper for the Mupen64Plus emulator. The purpose is to facilitate reinforcement learning interactions with games like Mario Kart 64 and Super Smash Bros. Although currently only these two games are wrapped, the environment is flexible enough to support any N64 game, granting you the ability to train your agents effectively.

Setting Up Your Environment

To dive into this project, the most streamlined approach is via Docker. Here’s how to set it up:

Pre-requisites

• Docker and Docker Compose installed on your machine.
• A copy of the ROMs you wish to use for the games.

Steps to Run the Project with Docker-Compose

1. Open your terminal and run the following command to build and run the project:

   sh
   docker-compose up --build -d
   

2. This command launches four containers:
   • xvfbsrv: Runs XVFB
   • vncsrv: Runs a VNC server connected to the Xvfb container
   • agent: Executes the example Python script
   • emulator: Runs the Mupen64Plus emulator
3. Connect to the VNC server using your preferred VNC client (for example, VNC Viewer) to observe the environment in action.

Understanding the Code

Now, let’s delve into the essence of the functional code and conceive it through an analogy. Imagine you are assembling a LEGO set. The various containers mentioned above are akin to different boxes, each filled with unique LEGO pieces:

• **xvfbsrv** is the box with the foundational base plates (XVFB), providing the ground where everything else will be built.
• **vncsrv** is like a miniature craft room (VNC server) where you need your special viewer to see the pieces assemble.
• **agent**, your adept builder, is the one expertly assembling pieces together following the instructions (Python script).
• **emulator** is the source of your imagination (Mupen64Plus emulator), turning your plans into reality!

Just like in building your LEGO project, everything has its role and once assembled perfectly, leads to an exciting playtime – that’s your AI agent navigating the N64 world!

Troubleshooting Tips

If you encounter issues during the setup or gameplay, consider the following troubleshooting ideas:

• Ensure Docker is correctly installed and running.
• Check if you have placed the ROMs in the correct location or adjust the .env file’s paths accordingly.
• If the VNC viewer fails to connect, ensure the server is also running correctly.
