source: code/trunk/src/orxonox/controllers/WaypointPatrolController.cc @ 6658

Last change on this file since 6658 was 6502, checked in by rgrieder, 15 years ago

Removed a ton of msvc warnings revealed with OGRE v1.7 (they removed the warning suppressors in OgrePrerequisites.h).
All of them are conversions from one type to another that might be lossy (mostly double to float, please always use "3.7f" instead of "3.7" as constants when using floats).
