hi folks...
thank you for your help....
and sorry for another stupid question (hope I won't get ignored =
sometime...)
(apart from some more problems:-) I just wanted my viewport to =
accompaign my robot. Thus I got a geometries position and set the =
vieports xyz pos to the bodies pos (just for the moment to give it a =
try). It worked fine just until my robot started to move (by hinge =
movement). As the getPosition method returns a const value, the position =
doesn't update. Then I tried something like
dVector3 camPos;
dBodyGetRelPointPos(myBodyID, 0, 0, 0, camPos);
and set the Viewport to this position. Nothing changed as this point =
also seems to stay the same. the adjustment of the camera pos works, as =
I am not able to move the camera by mouse movement.=20
So how do I get the current Position of a Body.
thanx for your help (and patience)...
cya&bfn, mike.
