While Lua support is no longer supported by Oxide for public plugins submitted on our site, you can still install the Lua extension for Oxide to enable .lua plugins written in Lua if your host allows it. Download the Oxide.Lua.zip extension and dependencies from AppVeyor (our build server) Completely shutdown the server so that it is no longer running in order to replace any existing files Move/upload the files you downloaded to the location where the rest of Oxide's files are installed at Examples: RustDedicated_Data/Managed for Rust, Hurtworld_Data/Managed for Hurtworld, etc. Startup the server and you're good to go! To install .lua plugins, simply place them under oxide/plugins Lua is no longer bundled in each Oxide build due to there not being enough interest and dedicated support for the language since C# replaced it as the primary language for public Oxide plugins. There are not many public plugins written in Lua remaining, but the extension will be maintained as necessary for basic plugin functionality.
