BeamMP-Server

This is the server for the multiplayer mod BeamMP for the game BeamNG.drive. The server is the point throug which all clients communicate. You can write lua mods for the server, detailed instructions on the BeamMP Wiki.

Minimum Requirements

These values are guesstimated and are subject to change with each release.

• RAM: 50+ MiB usable (not counting OS overhead)
• CPU: >1GHz, preferably multicore
• OS: Windows, Linux (theoretically any POSIX)
• GPU: None
• HDD: 10 MiB + Mods/Plugins
• Bandwidth: 5-10 Mb/s upload

Contributing

TLDR; Issues with the "help wanted" label or with nobody assigned, any trello cards in the "To-Do" column.

To contribute, look at the active issues and at the trello. Any issues that have the "help wanted" label or don't have anyone assigned and any trello cards that aren't assigned or in the "In-Progress" section are good tasks to take on. You can either contribute by programming or by testing and adding more info and ideas.

Fork this repository, make a new branch for your feature, implement your feature or fix, and then create a pull-request here. Even incomplete features and fixes can be pull-requested.

If you need support with understanding the codebase, please write us in the discord. You'll need to be proficient in modern C++.

About Building from Source

We only allow building unmodified (original) source code for public use. master is considered unstable and we will not provide technical support if such a build doesn't work, so always build from a tag. You can checkout a tag with git checkout tags/TAGNAME, where TAGNAME is the tag, for example v1.20.

Supported Operating Systems

The code itself supports (latest stable) Linux and Windows. In terms of actual build support, for now we usually only distribute windows binaries and sometimes linux. For any other distro or OS, you just have to find the same libraries listed in the Linux Build Prerequisites further down the page, and it should build fine. We don't currently support any big-endian architectures.

Recommended compilers: MSVC, GCC, CLANG.

You can find precompiled binaries under Releases.

Build Instructions

Do not compile from master. Always build from a release tag, i.e. tags/v2.0!

Currently only linux and windows are supported (generally). See Releases for official binary releases. On systems to which we do not provide binaries (so anything but windows), you are allowed to compile the program and use it. Other restrictions, such as not being allowed to distribute those binaries, still apply (see copyright notice).

Prerequisites

Windows

Please use the prepackaged binaries in Releases.

Dependencies for windows can be installed with vcpkg, in which case the current dependencies are the x64-windows-static versions of lua, zlib, rapidjson, boost-beast, boost-asio and openssl.

Linux / *nix

These package names are in the debian / ubuntu style. Feel free to PR your own guide for a different distro.

• git

• make

• cmake

• g++

• libcurl4-openssl-dev or similar (search for libcurl and look for one with -dev)

  Must support ISO C++17. If your distro's g++ doesn't support C++17, chances are that it has a g++-8 or g++-10 package that does. If this is the case. you just need to run CMake with -DCMAKE_CXX_COMPILER=g++-10 (replace g++-10 with your compiler's name).

• liblua5.3-dev

  Any 5.x version should work, but 5.3 is what we officially use. Any other version might break in the future. You can also use any version of libluajit, but the same applies regarding the version.

• libz-dev

• rapidjson-dev

• libopenssl-dev or libssl-dev

If you're building it from source, you'll need libboost1.70-all-dev or libboost1.71-all-dev or higher as well. If you can't find this version of boost (only 1.6x, for example), you can either update to a newer version of your distro, build boost yourself, or use an unstable rolling release (like Debian sid aka unstable).

In the end you should end up with a command something like this:

sudo apt install git make cmake g++-10 liblua5.3 libz-dev rapidjson-dev libopenssl-dev libboost1.71-all-dev

In the end you should end up with a command something like this:

sudo apt install git make cmake g++-10 liblua5.3 libz-dev rapidjson-dev libopenssl-dev libboost1.71-all-dev

How to build

On windows, use git-bash for these commands. On Linux, these should work in your shell.

1. Make sure you have all prerequisites installed
2. Clone the repository in a location of your choice with git clone --recurse-submodules https://github.com/BeamMP/BeamMP-Server.
3. Ensure that all submodules are initialized by running git submodule update --init --recursive. Then change into the cloned directory by running cd BeamMP-Server.
4. Checkout the branch of the release you want to compile (master is often unstable), for example git checkout tags/v1.20 for version 1.20. You can find the latest version here.
5. Run cmake . (with .)
6. Run make
7. You will now have a BeamMP-Server file in your directory, which is executable with ./BeamMP-Server (.\BeamMP-Server.exe for windows). Follow the (windows or linux, doesnt matter) instructions on the wiki for further setup after installation (which we just did), such as port-forwarding and getting a key to actually run the server.

tip: to run the server in the background, simply (in bash, zsh, etc) run: nohup ./BeamMP-Server &.
