Member Function Documentation

virtual void DtLuaScriptResourceManager::initializeNumberOfStates ( unsigned  numberOfStates )

virtual

Initializes the resource manager for the scenario, pre-allocating some resources based on the number supplied.

Implements DtScriptResourceManager.

virtual lua_State* DtLuaScriptResourceManager::getLuaState ( int  scriptType = DtScriptedTaskScriptedTask )

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, int  scriptType = DtScriptedTaskScriptedTask  )

static

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

static bool DtLuaScriptResourceManager::initializeVRFLuaExtensions ( lua_State *  L, const std::vector< std::string > &  scriptPaths, int  scriptType = DtScriptedTaskScriptedTask  )

static

Initializes a Lua state with the standard VRF Lua extensions.

static DtScriptResourceManager* DtLuaScriptResourceManager::creator ( )

static

Creator function for the Lua resource manager.

virtual std::string DtLuaScriptResourceManager::findLuaModuleFile ( const std::string &  filename )

protectedvirtual

Finds the full path to the given filename using the current script paths.

virtual void DtLuaScriptResourceManager::saveBytecodeChunk ( lua_State *  L, const std::string &  chunkName  )

protectedvirtual

Saves the top of the lua_State stack as a bytecode cache labeled as chunkName.

virtual void DtLuaScriptResourceManager::createLuaStates ( unsigned  numStates )

protectedvirtual

Creates a number of Lua states in parallel.
