source: code/branches/gui/src/core/Clock.h @ 1690

Last change on this file since 1690 was 1674, checked in by rgrieder, 16 years ago
  • Wrote Clock() class: It starts an internal clock when GSRoot starts and gets handed to all GameState ticks as reference. You can then either query the ticked time or the real time (for instance for statistical measurements)
  • general clean up in all the game states
  • Property svn:eol-style set to native
