// ball.h
// Project: Nostril (aka Postal)
//
//	History:
//	
//		01/19/97	JMI	Added some initializations to constructor.
//
//		01/27/97	JMI	Added override for EditRect() to make this object clickable.
//
//		02/02/97	JMI	Added EditHotSpot() override.
//
//		02/07/97	JMI	Added members for 3D.
//
//		02/07/97	JMI	Removed m_pipeline and associated members and setup since
//							the CScene now owns the pipeline.
//
//		02/13/97	JMI	Changing RForm3d to RSop.
//
//		02/23/97	JMI	Brought up to date so we can continue to use this as a
//							test object.
//
//		02/26/97	JMI	Now sets m_sprite.m_pthing = this on construction.
//
//		03/13/97	JMI	Load now takes a version number.
//
//		07/21/97	JMI	Added GetX(), GetY(), and GetZ().
