source: code/branches/objecthierarchy2/src/orxonox/overlays/OverlayText.cc @ 2672

Last change on this file since 2672 was 2369, checked in by landauf, 16 years ago
  • Added a health bar
  • Some changes in CameraManager to handle the case when no camera exists after removing the last one, but this is still somehow buggy (freezes and later crashes reproducible but inexplicable after a few respawns)
  • Added PawnManager to handle destruction of Pawns without using delete within tick()
  • Property svn:eol-style set to native
