Firstly, I'd like to second Martijn's sentiment - ODE (and PyODE) are very nice 
to work with. :)

Secondly - I have a problem that I hope someone has already solved, and that 
they can point me in the right direction...

I'm working on a physics-enabled boardgame environment ( 
http://groups.google.com/group/pyglet-users/web/geoffrey-a-board-game-environment
 ) and I'm using PyODE for selection and collision detection/physics. The 
selection code works perfectly (using glUnProject to position a GeomRay in the 
scene, then test for contacts with pieces) but I'm slightly stuck on *moving* 
the selected piece to keep it under the mouse pointer each frame.

First I tried setting it's position every frame, but that doesn't seem like the 
right way to do it, as collisions become unreliable. I tried setting it's 
linear velocity so that it would move to the target position each frame, but I 
couldn't get that working nicely either. I've experimented with attaching the 
object to *another* object, and setting *it's* position, but that didn't seem 
like the right solution - and applying a force (as per the 'thrust control 
logic' article in the wiki) didn't seem like it would solve my problem either.

Am I going about this the wrong way? I *do* seem to be fighting ODE for control 
of the object - is it back-to-front to think I can control an ODE object's 
exact position, while still having it collide with other objects? 


Any suggestions welcome. :)



Sincerely,

Simon Hildebrandt.
