I want to be able to work with several lua scripts. If several scripts have functions or variables with the same names, I have to make sure they do not override each other. As far as I understand, I need several lua states and/or threads for this, but I could not find all the info I need, neither in the lua nor in the luabind docs. What I'd like to have when I'm finished is sth like this:

Script *pScript = AddScript( "script.lua" );
ExecuteScript( pScript, "Update" );

Each script should have its own set of variables and functions, and all scripts should have access to a global set of variables. How can I achieve this? Any recommended reads on this apart from the official docs? Thank you!

You can make a class like this:

class Script {    lua_State* L;public:    Script() {         L = lua_open();    }    void AddScript(char* file) {        luaL_dofile(L, file);    }    void Execute(char* functionname) {        lua_getglobal(L, functionname);        lua_call(L, 0, 0);        lua_pop(L, 0);    }}
