// flagbase.cpp
// Project: Postal
//
// This module implements the flag object for capture the flag gameplay.
//
// History:
//
//		06/30/97 BRH	Started this file for the challenge levels.
//
//		07/12/97 BRH	Added FlagID so that flags can be matched with their
//							bases.  Added loading/saving thereof.  Also added
//							EditModify dialog so that the value can be set.
//
//		07/14/97 BRH	Changed to using the CSmash::Flagbase bits to identify
//							the base.  Also added checking for Flags to update
//							and incrementing the m_sFlagbaseCaptured value in realm
//							when the proper flag meets the base.
//
//		07/16/97 BRH	Changed to using the correct base files rather than
//							the bandguy as a placeholder.
//
//		08/03/97	JMI	Init() was setting the looping parms on a phot which no
//							longer exists.  Now the looping parms are passed via the
//							Get() call in GetResources() instead so they will get set
//							via the CAnim3D which should know which ones are okay to
//							use.
//
//		08/11/97 BRH	Added flagbase color option as a variable that is loaded
//							and saved and can be changed in the EditModify dialog.
//
//		08/18/97	JMI	Changed State_Dead to call DeadRender3D() (which used to be
//							known/called as just another Render() overload).
//
//		08/28/97 BRH	Set the correct bits to detect the flag base.   Finished
//							the code for capturing the flagbase.
