i added a new function, (get-pos) to get the position of an object from
the physics system.
i realized i was coding too early instead of thinking first again.
actually the physics system writes back all the transformation info to
the primitive which can be read simply like this:
define (get-pos)
(let ([t (get-global-transform)])
(vector (vector-ref t 12)
(vector-ref t 13)
(vector-ref t 14))))
i revert the git to the previous commit. sorry. hackpact pressure :).
feel free to tell me if i commit useless things :).
best,
gabor
