Question

I have very little experience in C or C++, so I don’t understand some of the various shortcuts and common tasks in the language.

I’m looking at game code that looks similar to this:

bool
update_frame (void)
{
  // Various bits of code
  return TRUE;
}

This is the main loop of the game. I’m thinking that it’s similar to something like:

while (true) {
  // do stuff
}

Which I would use in C# or Java. Is this what’s going on here?

Answer 1

This code is likely using a game engine. The engine will call update_frame 30/60/X times per second. In between, however, it might perform other tasks.

It probably functions as a while(true) loop, though.
