source: code/trunk/src/orxonox/objects/worldentities/Planet.cc @ 2938

Last change on this file since 2938 was 2896, checked in by landauf, 16 years ago

Merged gui branch back to trunk.

I did 2 small changes in IngameManager.cc on line 777 and 888 (yes, really), because const_reverse_iterator strangely doesn't work on MinGW.
