Changeset 4993 in orxonox.OLD for orxonox/trunk/src/lib


Ignore:
Timestamp:
Aug 13, 2005, 11:56:31 AM (19 years ago)

Message:

orxonox/trunk: reimplemented a greate part of PNode, so now it uses only relCoord/relDir to calculate the absolute direction
calling setAbsDir will invoke setRelDir in the process
