BulletSphericalConstraint Class Reference

A constraint between two rigid bodies, each with a pivot point. The pivot points are described in the body's local space. The constraint limits movement of the two rigid bodies in such a way that the pivot points match in global space. The spherical constraint can be seen as a "ball and socket" joint. More...

 Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More...
 
bool unref ()
 Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More...

Detailed Description

A constraint between two rigid bodies, each with a pivot point. The pivot points are described in the body's local space. The constraint limits movement of the two rigid bodies in such a way that the pivot points match in global space. The spherical constraint can be seen as a "ball and socket" joint.
