Re: btCompoundShape problem?
Looks like if I multiply colObj->getWorldTransform() with compoundshape->getChildTransform(j), the compound object (children) is falling down as expected. So the problem was in my draw function indeed. However, after the compound object is hitting the ground crazy stuff is going on. I wish I could m...

Re: btCompoundShape problem?
I added the bodies(btRigidBody) to a a list and this is fine for the compound object:
btVector3 pos = m_bodies->getCenterOfMassPosition();
So only children of the compound shape don't update properly ...
btVector3 pos = m_bodies->getCenterOfMassPosition();

Re: btCompoundShape problem?
Thanks for your reply. From the traces I see that getChildTransform() is not local: child position: (1 5 0) child position: (0 5 0) child position: (1 5 0) child position: (0 5 0) child position: (1 5 0) child position: (0 5 0) child position: (1 5 0) child position: (0 5 0) child position: (1 5 0) ...

btCompoundShape problem?
Hello, I am trying to add some btCompoundShape to my app and looks like it doesn't work. I made a siple test, please see the code and screenshot below: --> Setup the world: m_broadphase = snew btDbvtBroadphase(); m_collision_configuration = snew btDefaultCollisionConfiguration(); m_dispatcher = snew...

Re: btSphereShape friction
Thank you Adriano for your reply.
I was solving this following RollingFrictionDemo sample though, using setFriction & setRollingFriction to btRigidBody objects.

btSphereShape friction
Hello. I was making a huge btRigidBody that uses btBoxShape as ground and I have a cannon which fires spherical (using btSphereShape) bodies. Everything works fine, except after cannon balls hit the ground, they don't stop as expected (after awhile). As they don't use friction with the ground at all...

Re: Freezing a scene
It is possible to freeze/unfreeze only one object?
I can set mass to 0 to freeze it then when I want to unfreeze it put the mass back ... but I don't like the ideea verry much!
Is there any other way to do this?
Thank you!
