Module that provides access to basic server/client functions

🔧 gmsv_network ⚙️

A Garry's Mod binary serverside module that provide GLua access to basic server and client functions. Designed to replace the tracking of many events that require gm_sourcenet (which produces lua panic on many servers, corrupted message buffer reads, and decreased optimization). Currently under development.

Requirements

1. Garrysmod Common - A framework to facilitate the creation of compilations files (Visual Studio, make, XCode, etc). Simply set the environment variable GARRYSMOD_COMMON or the premake option --gmcommon=path to the path of your local copy of garrysmod_common.
2. Scanning Advanced - My helpful module contains symbols for sigscanning with garrysmod_common. Should be installed in third-party folder with name gmc_scanning_advanced.
3. (Linux) Installed gcc-multilib and g++-multilib packages.

All requirements already added in repository as submodules. Make sure that you clone them with recursive!
git clone https://github.com/klen-list/gmsv_network --recursive

Compiling

1. Download or install premake5
2. Enter the project folder and run:

• ./premake5.exe vs2019 (Windows with installed Visual Studio 2019 and locally placed premake5.exe)
• ./premake5 gmake (Linux with installed build-essential and locally placed premake5)
  ⚠️ If you catch Error: module 'premake-export-compile-commands/export-compile-commands' not found you didn't clone submodules correctly! Read above about clone command.

3. Move to projects/{os_platform}/{vs2019|gmake} and run gm_network.sln (Windows) or run make command (Linux)
