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

## Latest:

Performance optimizations across rendering, audio, and entity systems!
- Renderer: column-level frustum culling and compact visible-chunk lists skip thousands of empty iterations per frame; lightweight second-pass render path avoids redundant checks
- Sound engine: filesystem probe results are now cached, eliminating repeated file-existence checks every time a sound plays; sounds are pre-decoded for smoother playback
- Entity movement: reduced `shared_from_this()` overhead by caching the shared pointer; `dynamic_pointer_cast` replaced with a raw pointer cast guarded by `instanceof`
- Chunk updates: early-out for non-dirty chunks in the update loop; scaled recheck period at high render distances
- Threading: entity query locking consolidated at the `Level` layer on all platforms for consistent thread safety
- Block breaking: server now skips redundant tile-update packets when a block is successfully destroyed

Migrated to CMake build system (upstream)!
- Project now builds with CMake instead of Visual Studio project files
- Use `cmake --preset windows64` or open the repo folder directly in Visual Studio (it detects `CMakeLists.txt` automatically)
- Old `.vcxproj`/`.sln` files are preserved on the `vs-build` branch if needed

Multi-language font rendering and Unicode text input!
- Type and read text/characters in Japanese, Chinese, Korean, Thai, Arabic, Hindi, and many more languages
- Works in: chat, signs, world names, seeds, server address/port fields
- Two rendering systems: Iggy UI uses a new unicode bitmap fallback font; legacy C++ renderer uses Java Minecraft's glyph page system
- Arabic text shaping: proper contextual letter forms and right-to-left visual reordering in chat and UI
- Security: blocked Unicode bidirectional override characters to prevent chat spoofing
- Fixed a pre-existing memory leak in sign loading

Added copy+paste support for IP/Port, world names, world seeds, server names, signs, etc.
- Just use control+v to paste from your clipboard!

Dedicated server releases support Hardcore Mode!
- Dedicated server is fully compatible with `smartcmd/MinecraftConsoles` clients, even with hardcore mode!
- Client (`LCEWindows64.zip`): download from the Nightly release on GitHub
- Dedicated Server (`LCEServerWindows64.zip`): download from the Nightly-Dedicated-Server release on GitHub
- Docker: pull `ghcr.io/itsrevela/minecraft-lce-dedicated-server:nightly` for server container

In-game screenshot functionality with F2!
- pressing F2 will save a screenshot to a `screenshots` folder in your root game directory
- a local-only chat message is shown to the player notifying the screenshot filename that was saved

Proper implementation of Hardcore Mode in LCE!
- difficulty slider included in create world menu
- difficulty slider forces "Difficulty: Hardcore" on world load
- singleplayer: host death, force no respawn, on exit deletes world
- multiplayer: host death = world delete upon exit --- joiner death = only exit available, persists upon rejoin (no respawn option)
- multiplayer fixes: added fix to prevent host from using exit-without-saving loophole for nonhost players that died
- to-do: hardcore hearts texture

The current goal of MinecraftConsoles is to be a multi-platform base for further development, such as modding, backports, and anything else LCE. On top of that, we're working to make this a quality experience on Desktop with or without a controller while (long-term) retaining console support. 

See our our [Contributor's Guide](./CONTRIBUTING.md) for more information on the goals of this project.

## Download
### Client
Windows users can download our [Nightly Build](https://github.com/itsRevela/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)
### Server
If you're looking for Dedicated Server software (with hardcore-mode functionality), download its [Nightly Build here](https://github.com/itsRevela/MinecraftConsoles/releases/tag/Nightly-Dedicated-Server). Similar instructions to the client more or less, though see further down in this README for more info on that.

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

## LAN Multiplayer
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`
- Split-screen players can join in, even in Multiplayer

# Dedicated Server Software

## 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
```

## 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`


## Build & Run

1. Install [Visual Studio 2022](https://aka.ms/vs/17/release/vs_community.exe) or [newer](https://visualstudio.microsoft.com/downloads/).
2. Clone the repository.
3. Open the project folder from Visual Studio.
4. Set the build configuration to **Windows64 - Debug** (Release is also ok but missing some debug features), then build and run.

### CMake (Windows x64)

```powershell
cmake --preset windows64
cmake --build --preset windows64-debug --target Minecraft.Client
```

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