Hey Chad, thanks for your quick answer. It works the way you said,
awesome, thanks! But still, I have to write all this!?:
rotValues = OpenMaya.MScriptUtil()
rotValues.createFromDouble(0)
rotValuesPtr = rotValues.asDoublePtr()
matchQuaternion.get(rotValuesPtr)
print "x:%s, y:%s, z:%s" % (matchQuaternion.x,
matchQuaternion.y,
matchQuaternion.z)
I need to define a pointer to pass to the get() function although I
dont need it at the end!? Is that correct or can I skip some stuff
from my code?
thanks for your help
