The following commands are also missing and I believe this is just the tip of the iceberg:
void dbPhySetCharacterControllerDisplacement ( int iID, float fForward, float fBackward );
void dbPhySetCharacterControllerDisplacement ( int iID, float fX, float fY, float fZ );
void dbPhySetCharacterControllerDisplacement ( int iID, int iState );
void dbPhySetCharacterControllerSharpness ( int iID, float fValue );
void dbPhySetCharacterControllerExtents ( int iID, float fX, float fY, float fZ );
void dbPhySetCharacterControllerExtents ( int iID, float fRadius, float fHeight );
void dbPhySetCharacterControllerMinDistance ( int iID, float fValue );
void dbPhySetRigidBodyGroup ( int iObject, int iGroup );
Also, the lack of any search function in the help file has made quickly locating function help more difficult.
I'm personally now using the header file in combination with the PhysX SDK documentation which I'm finding much more informative.
No matter how good your code is, someone will improve on it
