I was wondering if it is possible with Lua to create modules. What I mean is: I want to create a script library with functions which then can be included in other lua files. For instance I want to create a script with all kinds of AI functions which I can call from all kinds of creature scripts. Unfortunately I can't find any documentation about this. Can anyone help me with this?

I am no expert on Lua but you can have one file say common.lua that contains a lot of functions in it. Then, when you're initializing your program, you can register them all with your lua_state* as follows:

lua_State* vm = lua_open( );
lua_dofile( vm, "common.lua" );

Now any other functions or files executed in reference to this lua_State* should have all of the functions defined in common.lua defined.

Hope this helps.

Yes, it helps a bit. Though it is not exactly what I want to achive. I want to let a user create his/her own library of functions. But I think that I found it. By adding: require "filename" to the top of the lua script script, you can include other lua files and thus create something like modularity :-).

Thanks anyway!
