Changeset 2369 for code/branches/objecthierarchy2/src/orxonox/objects/worldentities/pawns

Timestamp:

Dec 10, 2008, 3:37:48 AM (16 years ago)

Author:

Message:

• 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()

Location:

code/branches/objecthierarchy2/src/orxonox/objects/worldentities/pawns

Files:

• Pawn.cc (modified) (8 diffs)
• Pawn.h (modified) (2 diffs)
