[ODE] Presentation and question

[Shaul Kedem]

Ricard,
 Did you use the latest cvs snapshot and enabled
OPCODE?
 If you didn't my email should not concern you.

 About your problem - how do you keep the box in the
air ? You say all you do is get the position and
rotation of the box but I fear you have at least
created a world, a space a geom and a body, and
supplied a callback.

Best,
Shaul
