virtual

Returns a new Lua state.

virtual bool DtLuaScriptResourceManager::loadModule ( lua_State *  L, const std::string &  moduleName  )

virtual

Loads a module with the given name into the Lua state. Returns true if successful.

static lua_State* DtLuaScriptResourceManager::createLuaState ( const std::vector< std::string > &  scriptPaths, bool  forBackgroundProcess = false  )

static

Creates and initializes a new Lua state with the given paths.
