## Introduction

This project contains the source code of Minecraft Legacy Console Edition v1.6.0560.0 (TU19) with some fixes and improvements applied.

## Download
Windows users can download our [Nightly Build](https://github.com/smartcmd/MinecraftConsoles/releases/tag/nightly)! Simply download the `.zip` file and extract it to a folder where you'd like to keep the game. You can set your username in `username.txt` (you'll have to make this file)

## Platform Support

- **Windows**: Supported for building and running the project
- **macOS / Linux**: The Windows nightly build may run through Wine or CrossOver based on community reports, but this is unofficial and not currently tested by the maintainers

## Features

- Fixed compilation and execution in both Debug and Release mode on Windows using Visual Studio 2022
- Added support for keyboard and mouse input
- Added fullscreen mode support (toggle using F11)
- (WIP) Disabled V-Sync for better performance
- Added a high-resolution timer path on Windows for smoother high-FPS gameplay timing
- Device's screen resolution will be used as the game resolution instead of using a fixed resolution (1920x1080)
- LAN Multiplayer & Discovery
- Added persistent username system via "username.txt"

## Multiplayer

Basic LAN multiplayer is available on the Windows build

- Hosting a multiplayer world automatically advertises it on the local network
- Other players on the same LAN can discover the session from the in-game Join Game menu
- Game connections use TCP port `25565` by default
- LAN discovery uses UDP port `25566`
- Add servers to your server list with the in-game Add Server button (temp)
- Rename yourself without losing data by keeping your `uid.dat`

Parts of this feature are based on code from [LCEMP](https://github.com/LCEMP/LCEMP) (thanks!)

### Launch Arguments

| Argument           | Description                                                                                         |
|--------------------|-----------------------------------------------------------------------------------------------------|
| `-name <username>` | Sets your in-game username.                                                                         |
| `-fullscreen`      | Launches the game in Fullscreen mode                                                                |

Example:
```
Minecraft.Client.exe -name Steve -fullscreen
```

## Dedicated Server in Docker (Wine)

This repository includes a lightweight Docker setup for running the Windows dedicated server under Wine.
### Quick Start (No Build, Recommended)

No local build is required. The container image is pulled from GHCR.

```bash
./start-dedicated-server.sh
```

`start-dedicated-server.sh` does the following:
- uses `docker-compose.dedicated-server.ghcr.yml`
- pulls latest image, then starts the container

If you want to skip pulling and just start:

```bash
./start-dedicated-server.sh --no-pull
```

Equivalent manual command:

```bash
docker compose -f docker-compose.dedicated-server.ghcr.yml up -d
```

### Local Build Mode (Optional)

Use this only when you want to run your own locally built `Minecraft.Server` binary in Docker.
**A local build of `Minecraft.Server` is required for this mode.**

```bash
docker compose -f docker-compose.dedicated-server.yml up -d --build
```

Useful environment variables:
- `XVFB_DISPLAY` (default: `:99`)
- `XVFB_SCREEN` (default: `64x64x16`, tiny virtual display used by Wine)

Fixed server runtime behavior in container:
- executable path: `/srv/mc/Minecraft.Server.exe`
- bind IP: `0.0.0.0`
- server port: `25565`

Persistent files are bind-mounted to host:
- `./server-data/server.properties` -> `/srv/mc/server.properties`
- `./server-data/GameHDD` -> `/srv/mc/Windows64/GameHDD`

### About `server.properties`

`Minecraft.Server` reads `server.properties` from the executable working directory (Docker image: `/srv/mc/server.properties`).
If the file is missing or contains invalid values, defaults are auto-generated/normalized on startup.

Important keys:

| Key | Values / Range | Default | Notes |
|-----|-----------------|---------|-------|
| `server-port` | `1-65535` | `25565` | Listen TCP port |
| `server-ip` | string | `0.0.0.0` | Bind address |
| `server-name` | string (max 16 chars) | `DedicatedServer` | Host display name |
| `max-players` | `1-8` | `8` | Public player slots |
| `level-name` | string | `world` | Display world name |
| `level-id` | safe ID string | derived from `level-name` | Save folder ID; normalized automatically |
| `level-seed` | int64 or empty | empty | Empty = random seed |
| `world-size` | `classic\|small\|medium\|large` | `classic` | World size preset for new worlds and expansion target for existing worlds |
| `log-level` | `debug\|info\|warn\|error` | `info` | Server log verbosity |
| `autosave-interval` | `5-3600` | `60` | Seconds between autosaves |
| `white-list` | `true/false` | `false` | Enable access list checks |
| `lan-advertise` | `true/false` | `false` | LAN session advertisement |

Minimal example:

```properties
server-name=DedicatedServer
server-port=25565
max-players=8
level-name=world
level-seed=
world-size=classic
log-level=info
white-list=false
lan-advertise=false
autosave-interval=60
```

### Dedicated Server launch arguments

The server loads base settings from `server.properties`, then CLI arguments override those values.

| Argument | Description |
|----------|-------------|
| `-port <1-65535>` | Override `server-port` |
| `-ip <addr>` | Override `server-ip` |
| `-bind <addr>` | Alias of `-ip` |
| `-name <name>` | Override `server-name` (max 16 chars) |
| `-maxplayers <1-8>` | Override `max-players` |
| `-seed <int64>` | Override `level-seed` |
| `-loglevel <level>` | Override `log-level` (`debug`, `info`, `warn`, `error`) |
| `-help` / `--help` / `-h` | Print usage and exit |

Examples:

```powershell
Minecraft.Server.exe -name MyServer -port 25565 -ip 0.0.0.0 -maxplayers 8 -loglevel info
Minecraft.Server.exe -seed 123456789
```

2. Clone the repository.
3. Open the project by double-clicking `MinecraftConsoles.sln`.
4. Make sure `Minecraft.Client` is set as the Startup Project.
5. Set the build configuration to **Debug** (Release is also ok but missing some debug features) and the target platform to **Windows64**, then build and run.

### CMake (Windows x64)

```powershell
cmake -S . -B build -G "Visual Studio 17 2022" -A x64
cmake --build build --config Debug --target MinecraftClient
```

For more information, see [COMPILE.md](COMPILE.md).

## Known Issues

- Native builds for platforms other than Windows have not been tested and are most likely non-functional. The Windows nightly build may still run on macOS and Linux through Wine or CrossOver, but that path is unofficial and not currently supported
