m_collisionFlags !=btCollisionObject::CF_STATIC_OBJECT ?!?

[SteveBaker]

OK - I give up - what is this assert telling me?

../bullet/src/BulletDynamics/Dynamics/btRigidBody.h:199: void btRigidBody::setLinearVelocity(const btVector3&): Assertion `m_collisionFlags !=btCollisionObject::CF_STATIC_OBJECT' failed.

You should not set the linear velocity for static objects. Only dynamic and/or kinematic objects can ever move. Do you have a full callstack which system is trying to set the linear velocity? It might be a bug,
Thanks,

Probably it should be !(m_collisionFlags & btCollisionObject::CF_STATIC_OBJECT) instead of m_collisionFlags !=btCollisionObject::CF_STATIC_OBJECT. No?

Definately. I'll change it in the more readable 'isStaticObject()', which is the same.

Thanks Jack,
