source: orxonox.OLD/branches/terrain/src/lib/collision_detection/cd_engine.cc @ 8465

Last change on this file since 8465 was 8328, checked in by ponder, 18 years ago
  • Renamed Terrain into TerrainEntity in order to avoid conflicts between the importer/terrain class and the world_entities/terrain.
  • Changed TerrainEntity to support the new terrain class.
