I can get a global int into C++, but having trouble with tables: settings.lua reads: ------------------ testValue = 100 video = { fullscreen=0, [other-video-stuff] } audio = { [audio-settings] } player = { etc } C++ code that can get testValue: -------------------------------- luaL_loadfile(lua_state, "settings.lua"); lua_pcall(lua_state, 0,0,0); lua_getglobal(lua_state, "testValue"); int t = lua_tonumber(lua_state,-1); std::cout << "t=" << t << ".\n"; How do I get the number video.fullscreen into t?

try:


lua_pushstring( lua_state, "video" );
lua_gettable( lua_state, LUA_GLOBALSINDEX );
lua_pushstring( lua_state, "fullscreen" );
lua_gettable( lua_state, -2 );

int iFullscreen = (int)lua_tonumber( lua_state, -1 );

// clean up lua stack
lua_pop( lua_state, lua_gettop( lua_state ) );

Hey thanks, that did the trick!
app now picks screen mode based on lua text file.

CreateWindowEx:
(fullscreen ? WS_POPUP|WS_EX_TOPMOST : WS_OVERLAPPEDWINDOW)

D3DPRESENT_PARAMETERS
screen_presentation.Windowed = !fullscreen
