visual C 8 game loop
Author
anyone know how to implement a game loop with the code generated by the win32 app project?
// Main message loop:while (GetMessage(&msg, NULL, 0, 0)) { if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)) { TranslateMessage(&msg); DispatchMessage(&msg); }}change that to:
// Main message loop:while(!done) {while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) { if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)) { TranslateMessage(&msg); DispatchMessage(&msg); }}// Update game hereBut i suggest you reed a tutorial on how to make a real game loop and dont use the app created by windows you have more control if you make your own app..

Will this work?
do { if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) { if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)) { if (msg.message == WM_QUIT) break; TranslateMessage(&msg); DispatchMessage(&msg); } } else { //game stuff } } while(TRUE);Quote:Original post by etsuja

Well, it will work, but is that really how you want it? (And out of curiousity, why use a do{}while() loop in place of a while() loop or maybe even for()?)
But what if you did this:
while(true) { // makes my life easier :D get_message(&message); // don't know win32, help me out here! switch (message.code) { // again, win32 case QUIT: // need I say it? break; // oh-oh! break; case KEYDOWN: // super-cool keydown! break; }}The break would break the switch, not the while loop.... so I would do instead something like:
for (bool done = false; !done; /*none*/) { // makes my life easier :D get_message(&message); // don't know win32, help me out here! switch (message.code) { // again, win32 case QUIT: // need I say it? done = true; // walla! break; case KEYDOWN: // super-cool keydown! break; }}Just a heads-up.
Just follow SmurfKiller's advice as this is the way I do it and it does the job perfectly.
However, You probably will not need the TranslateAccelerator function in your game as this will only be wasted cycles. If you don't intend on processing the WM_CHAR message then you don't need the TranslateMessage function either.

The best way is simply something like this: -
This is the normal game loop for a muti-platform, client only game. All of the main computation is taken off and handled by the respective objects.
NOTE: The input here will be handled by some for of input API, DirectInput maybe for Win32 systems.
// main game loopwhile(g_pGame->IsRunning()){ // clear the screen g_pGraphicsManager->ClearScreen(); // get the frame time float fFrameTime = g_pTimeManager->GetFrameTime(); // get the user input g_pInputManager->Update(fFrameTime); // update AI logic g_pAIManager->Update(fFrameTime); // update game logic g_pGame->Update(fFrameTime); // update audio g_pAudioManager->Update(fFrameTime); // render the scene g_pGraphicsManager->RenderScene(fFrameTime);}This is the normal game loop for a muti-platform, client only game.

My game loop looks like this
MSG msg = {};while(msg.message != WM_QUIT){ if(PeekMessage(&msg, 0, 0, 0, PM_REMOVE)) DispatchMessage(&msg); else RunFrame();}This topic is closed to new replies.
