🌑 rglua

This is a crate that allows interop with the (g)luajit c api as well as the source sdk through libloading and vtable bindings. You can then use these for binary modules or manually injected code, like with Autorun-rs

More information on binary modules can be found on the garrysmod wiki: Creating Binary Modules and examples can be found here.

Usage

If you are targeting 32 bit make sure to install the toolchain and build to it:

rustup target add i686-pc-windows-msvc
cargo build --target=i686-pc-windows-msvc

garrysmod_common

This is heavily based off of garrysmod_common, in how we export the lua_shared functions and trying to replicate everything from the Lua C Api.
