vg4->misc->wait_time()

int vg4->misc->wait_time(int m_sec)

Returns the actual slept time

Sleep the rest of a defined time. This function is mainly used in a game-loop, because each game-loop should take the same time. The executing code will take some time, and so this function sleeps the rest of the time defined in m_sec. Of course the time in m_sec should not be too small to avoid overruns.

/* Example: each game-loop should take 50 milliseconds */

/* game-loop */
for (;;) {
  if (!vg4->input->update(VG_TRUE)) { break; }

  [... execute some code ...]

  /* now sleep the rest of 50 milliseconds this game-loop should take */
  vg4->misc->wait_time(50);
}
