Graphics loops

[jmiller]

I've programmed games in visual basic that have used graphical loops, but i'm not sure how to go about it in C++. In a windowed environment, isn't there always a loop running (the message loop)?

if this loop has to be there in order to communicate with windows, does the graphics loop have to go inside this loop? i can't image how you could have two loops running at the same time.

thanks,

You are using MFC or just plain Win32 programming?

Modify the message loop to look like this:

for(;;)
{
  if(PeekMessage(&msg, 0, 0, 0, PM_REMOVE))
  {
    if(msg.message == WM_QUIT)
      break;
    TranslateMessage(&msg);
    DispatchMessage(&msg);
  }
  // Game stuff here
}

or you could make a new thread

CornedBee: Why do you use a for-loop? Is it faster than a while-loop?

[CornedBee]

I always use for(;; ) for infinite loops, it's shorter to write than while(true) and while(1) isn't C++-like.

Except if you have a very stupid compiler (an anti-optimizing compiler so to say ) they are both exactly the same speed.
