English | 简体中文

LiteLoaderBDS is an unofficial plugin loader that provides basic API support for Bedrock Dedicated Server, with a massive API, lots of packed utility interfaces, a rich event system and powerful basic interface support.

LiteLoader provides a massive API, a powerful event system and a large number of encapsulated development infrastructure interfaces, providing a solid foundation for extending the Bedrock Edition BDS with more gameplay and functionality. With plugins, it is easy to extend the functionality of BDS, the associated development is easy to learn, and the development approach is flexible.

Writing plugins in C++, JavaScript, Lua, C# and other languages, which allows developers to easily extend and customize BDS functionality, making it easy to learn and extremely flexible.

🎁 First impression

“Why should I choose LiteLoader?”

They have interface that is easy to use and intuitive!!

C++ language sample plugin

// Template project: https://github.com/LiteLDev/PluginTemplate
// More examples: https://github.com/LiteLDev/LiteLoaderPlugins
#include <llapi/EventAPI.h>
#include <llapi/LoggerAPI.h>
#include <llapi/LLAPI.h>
#include <llapi/mc/Actor.hpp>
#include <llapi/mc/Player.hpp>

Logger logger("AttackLog");

void PluginInit() {
    logger.info("Plugin xxx has been loaded.");
    // Subscribe Player-Attack Event
    Event::PlayerAttackEvent::subscribe([](const Event::PlayerAttackEvent& ev) {
        Player* player = ev.mPlayer;
        Actor* actor = ev.mTarget;
        logger.info("Player:{} attacks {} | at {} in Dimension {}",
            player->getRealName(), actor->getTypeName(), 
            actor->getPos().toString(), std::to_string(actor->getDimensionId())
        );
        return true;
    });
}

Script language sample plugin (Use Js as an example)

// Register for shutdown command
mc.listen("onServerStarted", () => {
    const cmd = mc.newCommand("stopsvr", "close server");
    cmd.overload();
    cmd.setCallback((_cmd, ori, out, _res) => {
        out.success("stop command executed successfully");
        mc.broadcast(
            `${ori.player.realName} executed the stop command. The server will be shutdown after 5 seconds`
        );

        // Execute stop command
        setTimeout(() => mc.runcmd("stop"), 5000);
    });
    cmd.setup();
});

💻 Install

For Windows

Download the latest LiteLoader-version.zip from Releases or Actions,
Unzip everything into the directory of bedrock_server.exe. If you are prompted with conflicting files during the decompression process, just select Overwrite.
Ensure that the bedrock_server.pdb file exists. Run LLPeEditor.exe to generate the BDS with the exported symbols (bedrock_server_mod.exe)
When the console output Press any key to continue . . . , press any key to close the window
Execute bedrock_server_mod.exe and enjoy it!

For Linux

We do not recommend you to use Wine due to BDS 1.19.20+ on Wine has a performance problem

Installation script(Ubuntu)

wget https://github.com/LiteLDev/LiteLoaderBDS/raw/develop/scripts/install.sh && sh install.sh

Docker

Enter the following lines in your terminal:

docker pull shrbox/liteloaderbds
mkdir <install directory>
docker create --name llbds -v <install directory>:/root/bedrock-server -p 19132:19132/udp -i -t shrbox/liteloaderbds

<install directory> is directory to store data, for example: /home/shrbox/bedrock-server
The first boot takes a little while to download the Bedrock Dedicated Server and LiteLoaderBDS
Start server: docker container start llbds -a
Force stop server(not recommended): docker container stop llbds
Enter console: docker attach llbds
Exit console: Press Ctrl + P + Q. If you press Ctrl + C, the server process will exit.

Everything's done! Next, you can install LiteLoader plugins!

🔨 Build project

Go to GitHub Actions to get the latest build artifact

Of course, if you prefer to build the project yourself, or contribute code to LiteLoader, you can build the project yourself by following these instructions

Install the latest version of Microsoft Visual Studio and the standard C++ desktop development suite (or you can just install the full msbuild compiler suite and configure the compilation environment)
Install the latest Windows SDK.
Use your familiar IDE (VS / VSCode / CLion, etc.) to open the project directory and compile the cmake project.
After successful compilation, go back to the project root directory and execute the PackRelease.cmd script in the Scripts folder.
After execution, the contents of the RELEASE folder in the root directory will be the complete LiteLoader environment and all dependencies.
If you need extra debugging symbols of LL, execute another PackReleaseWithPDB.cmd script, and the RELEASE folder will be filled with all necessary debugging symbols for easy debugging
