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

For Linux, you need the runtime dependencies, listed below under "prerequisites".

Contributing

TLDR; Issues with the "help wanted" label or with nobody assigned.

To contribute, look at the active issues. Any issues that have the "help wanted" label or don't have anyone assigned 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 check out a tag with git checkout tags/TAGNAME, where TAGNAME is the tag, for example v1.20.

Supported Operating Systems

The code itself supports (the 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/v2.3.3!

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. These are:

> vcpkg install lua:x64-windows-static zlib:x64-windows-static rapidjson:x64-windows-static openssl:x64-windows-static websocketpp:x64-windows-static curl:x64-windows-static

Linux

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

Runtime dependencies for linux:

Debian / Ubuntu

$ sudo apt install libz-dev rapidjson-dev liblua5.3-dev libssl-dev libwebsocketpp-dev libcurl4-openssl-dev git make cmake g++

For other distributions (e.g. Arch) you want to find packages for:

libz
rapidjson
lua5.3
ssl / openssl
websocketpp
curl (with ssl support)
+ the build time dependencies from above

macOS

Dependencies for macOS can be installed with homebrew.

brew install lua@5.3 rapidjson websocketpp cmake openssl@1.1

Some packages are included in macOS, but you might want to install homebrew versions.

brew install curl zlib git make

How to build

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

Make sure you have all prerequisites installed
Clone the repository in a location of your choice with git clone -b v3.0.2-WithPython --recurse-submodules https://github.com/SantaSpeen/BeamMP-Server.
Change into the BeamMP-Server directory by running cd BeamMP-Server.
Ensure that all submodules are initialized by running git submodule update --init --recursive. Then change into the cloned directory by running cd BeamMP-Server.
Run cmake . -DCMAKE_BUILD_TYPE=Release (with .)
Run make -j 4 (Set -j {cores in your CPU}. This param use for quickly compile.)
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, doesn't 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 &.

Support

The BeamMP project is supported by community donations via our Patreon. This brings perks such as Patreon-only channels on our Discord, early access to new updates, and more server keys.
