# OpenTTD JGRPP Docker Server

This setup builds OpenTTD with the JGR Patch Pack (JGRPP) from source and runs it in a Docker container.

## Getting Started

1.  **Build and start the server:**
    ```bash
    docker-compose up -d --build
    ```

2.  **Accessing the console:**
    ```bash
    docker exec -it openttd-jgrpp openttd -D
    ```
    (Actually, the server runs in dedicated mode. You can view logs with:)
    ```bash
    docker-compose logs -f
    ```

3.  **Configuration:**
    The configuration is stored in `config/openttd.cfg`. The default password is set to `asd`.

4.  **Save Games:**
    Save games are stored in `config/save/`.

## JGRPP Source
The source code is cloned from the `jgrpp` branch of `https://github.com/JGRennison/OpenTTD-patches`.
To update the server to a newer JGRPP version:
1.  Update the `OpenTTD-patches` directory:
    ```bash
    cd OpenTTD-patches && git pull && cd ..
    ```
2.  Rebuild the image:
    ```bash
    docker-compose up -d --build
    ```
