// AnimThing.H
// Project: Nostril (aka Postal)
// 
// History:
//		02/18/97 JMI	Started.
//
//		02/19/97	JMI	Added ability to send any message to any CThing when done
//							with animation.
//
//		02/19/97	JMI	Unprotected more members.
//
//		02/24/97	JMI	Changed declaration of m_sprite from CAlphaSprite2 to 
//							CSprite2.
//
//		02/24/97	JMI	Changed m_pthingSendMsg to m_u16IdSendMsg.
//
//		02/26/97	JMI	Now sets m_sprite.m_pthing = this on construction.
//
//		03/13/97	JMI	Load now takes a version number.
//
//		06/24/97	JMI	Now intializes m_msg's priority to 0 on construction for
//							safety.
//
//		07/21/97	JMI	Added GetX(), GetY(), and GetZ().	
//

//
// This CThing-derived class will play an animation to its finish and then
// destroy itself.  It's a mini Postal movie player.
