• Call GM functions and scripts from Lua scripts (thanks to GMAPI)
• Call Lua functions from GM
• Simple events system

Look above for download!

You can compile gmLua yourself. It depends on two libraries: GMAPI and Lua5.

GMAPI is written by a Polish programmer, Snake, you can download it ( http://gmc.yoyogames.com/index.php?showtopic=429267 ). It allows you to interact with GM from C++.

You can download the Lua binaries: http://gmlua.googlecode.com/files/lua5_1_4_Win32_dll8_lib.zip. gmLua is developed and compiled with Microsoft Visual C++ 2008, the source includes a project file. Please note, that gmLua is currently unavailable on Game Maker OS X version, because GMAPI doesn't work on these OS.

luaStart();

lua = luaNew();

if(!lua)
{
    show_error("Failed to create Lua state.", true);
}

luaRegister(lua, "showMessage", showMessage);
luaLoadFile(lua, get_string("Type your Lua script path (default: game.lua)", "game.lua"));
luaEvent(lua, "onCreate", 1, id);

function onCreate(id) -- onCreate, called from GML.
    showMessage("ID: " .. tostring(id))
end
