face collision toggle problems

Heyya,
I’m making an activity that involves clicking and dragging objects onto each other. The setup is quite simple: When you click on an object, it activates it and it follows the mouse x and z positions (using a modifier based on distance from camera). When that happens I replace the objects mesh with one that looks identical but has no collision. I do that so I can click on other objects after I’ve picked up the first one.

The problem is… my new mesh isn’t keeping it defined collision detection, its keeping the old meshes one. I’ve checked to make sure that the new mesh is actually getting added in. The result is, once I’ve picked up my first object, I can’t pick up another because the mouse clicks are getting absorbed by the object I’m dragging.

I’ve googled and searched BlenderArtists forum for answers to why my mesh might not be changing its collision or even how to turn off collision using python but I haven’t found anything.

Does anyone know how to solve my problem? Or know the python commands to remove all collision from an object?

Cheers,
Dave

its a pretty old ‘bug’ (the python function to update mesh collision shapes doesn’t work), we may find that in the cleanup

Ack. Oh well… I’m sure I’ll figure out a hack to get around it. Thanks for your reply!
