# BeamMP-Server
[![CMake Windows Build](https://github.com/BeamMP/BeamMP-Server/workflows/CMake%20Windows%20Build/badge.svg?branch=master)](https://github.com/BeamMP/BeamMP-Server/actions?query=workflow%3A%22CMake+Windows+Build%22)
[![CMake Linux Build](https://github.com/BeamMP/BeamMP-Server/workflows/CMake%20Linux%20Build/badge.svg?branch=master)](https://github.com/BeamMP/BeamMP-Server/actions?query=workflow%3A%22CMake+Linux+Build%22)
This is the server for the multiplayer mod **[BeamMP](https://beammp.com/)** for the game [BeamNG.drive](https://www.beamng.com/).
The server is the point throug which all clients communicate. You can write lua mods for the server, detailed instructions on the [BeamMP Wiki](https://wiki.beammp.com).
## 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](https://github.com/BeamMP/BeamMP-Server/issues) with the "help wanted" label or with nobody assigned, any [trello](https://trello.com/b/Kw75j3zZ/beamngdrive-multiplayer) cards in the "To-Do" column.
To contribute, look at the active [issues](https://github.com/BeamMP/BeamMP-Server/issues) and at the [trello](https://trello.com/b/Kw75j3zZ/beamngdrive-multiplayer). 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](#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](https://github.com/BeamMP/BeamMP-Server/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](https://github.com/BeamMP/BeamMP-Server/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](#copyright)).
### Prerequisites
#### Windows
Please use the prepackaged binaries in [Releases](https://github.com/BeamMP/BeamMP-Server/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`).
### 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](#prerequisites) installed
2. Clone the repository in a location of your choice with **`git clone --recurse-submodules https://github.com/BeamMP/BeamMP-Server`**. Now change into the cloned directory by running `cd 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](https://github.com/BeamMP/BeamMP-Server/tags).
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](https://wiki.beammp.com/en/home/Server_Mod) 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 &`*.*
