This page contains some of the C++ plugins that I coded for a game called GarrysMod (GMod) . You must purchase GarrysMod to use these. Each project has the source code and the compiled plugin in seperate links. Most likely, you'd only be downloading these plugins if you knew how to use them, therefore do not contact me saying that you don't know what these are for and/or don't know how to use them.
To install, drop the dll file into the "*/garrysmod/garrysmod/lua/includes/modules/" folder and activate the functions using the Lua command: require("modulename")
