source: orxonox.OLD/orxonox/trunk/src/game_loader.cc @ 3013

Last change on this file since 3013 was 2636, checked in by patrick, 20 years ago
  • Added a GameLoader to the game. This enables orxonox to load a campaign consisting of multimple worlds and cinematics etc. However, cinematics are not yet implemented.

In the game you can jump from one level to the other by pressing x. Currently there are only two very simple levels defined. (DEBUG_LEVEL_0, DEBUG_LEVEL_1).

  • Added Error Handling structs to signal the error source and code
