I want to define a box shape that has a position, probably an orientation...
How can I achieve this?
Thanks

you just set the world transform on the collision object / rigid body that's using that shape. So define your box shape, and then attach it to a collision object and update that.

The answer to this question is in every sample and in the wiki and in the manual. You can do this!

Hi there,
Can I just create a shape without attaching any collision object to it, I need it for cooperative pathfinding
as a placeholder...
Thanks

A shape by itself really doesn't do very much, and won't detect any collisions for you, you really need a collision object,rigidy body, ghost object , whatever to get anything meaningful picked up. You can even just have one collision shape (box) and lots of collision objects sharing it.

Okay, thank you then, let me take some read on the documentation first.
Thanks
Jack

There is a method to get a transformed aabb from a collision shape by passing in a transformation. But as xexuxjy is saying collision shapes don't themselves have a transform ... that's something the collision object handles (btCollisionObject -> btRigidBody and others)
