New Revision: 2780

Modified:
   trunk/src/orxonox/objects/worldentities/MobileEntity.cc
Log:
Checking whether a function really does what you think might sometimes help ;)
Bullet stores the transformation as matrix, not as vector and quaternion like ogre.

This little fix equals a speed gain of about 1.4% in dedicated mode without clients and 30 bots.
