//
// This module implements the CMine weapon class which is a hand
// thrown grenade weapon.
// 
//
// History:
//		03/19/97 BRH	Started this weapon object.
//
//		03/19/97 BRH	Added 4 types of mines to this file.  Still need to
//							create a dialog in the gui editor to select which type
//							of mine to place in the editor.  Also need to add motion
//							functions to the base class and use them for the 
//							Bouncing Betty in Update.
//
//		03/20/97 BRH	Added dialog box for selecting mine type.  Still need to
//							do the bouncing betty mine.
//
//		03/21/97 BRH	Added the Bouncing Betty functionality.
//
//		04/10/97 BRH	Updated this to work with the new multi layer attribute
//							maps.
//
//		04/15/97 BRH	Added fuse timer dialog item to edit modify to allow
//							the timed mine fuse to be set.  Also added an overloaded
//							Setup() function to set the time for the fuse.  Changed
//							Load and Save to deal with this new fuse value.
//
//		04/23/97	JMI	Now sets its m_smash's bits to Mine instead of Item.
//
//		04/25/97	JMI	Added angle Z (vertical angle adjustment) of 0 to the
//							CBulletFest::Fire(...) call.
//
//		04/29/97	JMI	Changed State_Fire to merely jump to State_Idle.  The
//							reason is that CCharacter uses State_Fire to notify things
//							that they should arm.  Perhaps this state should be changed
//							to 'arm', but, technically, some things don't really even
//							arm until after that.  Perhaps it should be State_Go or
//							something.
//							Anyways, in order to use State_Fire as the 'arm' trigger
//							from the placer, I had to change State_Go to do what State_Fire
//							used to for the bouncing betty; namely, wait for the time
//							to expire.
//							Also, Render() now subtracts half the width and half the
//							height from the 2D render location in an attempt to better
//							center the image.  This should help especially when this
//							object is the child of another to make it appear in the
//							right spot.
//
//		04/30/97	JMI	Changed the Setup() override of the CWeapon's Setup() to
//							pass the current mine type to the Setup() with eType.
//							Changed Construct() to take an ID as a parameter and added
//							ConstructProximity(), ConstructTimed(), 
//							ConstructBouncingBetty(), and ConstructRemoteControl() to 
//							allocate that type of mine.
//							Removed m_eMineType (now uses Class ID instead).
//							Removed Setup() that took an eType.
//							Filled in PreLoad() (but it still needs to convert each
//							RImage to whatever type is most efficient).
//							Also, GetResources() was new'ing m_pImage and then calling
//							rspGetResource() (which gives you an entirely new instance
//							of an image); so it was basically wasting an RImage worth
//							of memory.
//
//		05/28/97 BRH	Increased arming time for Betty and Proximity mines to make
//							them easier to place and get away.
//
//		05/29/97	JMI	Removed ASSERT on m_pRealm->m_pAttribMap which no longer
//							exists.
//
//		06/11/97 BRH	Added shooter ID's to the shot messages and passed it
//							along to the explosion.
//
//		06/12/97 BRH	Added shooter ID to the call to Setup for the explosion.
//
//		06/13/97	JMI	Now obeys State_Hide.
//
//		06/30/97 BRH	Added cache sound effects to Preload function.
//
//		07/09/97	JMI	Now uses m_pRealm->Make2dResPath() to get the fullpath
//							for 2D image components.
//
//		07/09/97	JMI	Changed Preload() to take a pointer to the calling realm
//							as a parameter.
//
//		07/18/97	JMI	Got rid of bogus immitation PlaySample functions.
//							Now there is one PlaySample() function.  Also, you now
//							MUST specify a category and you don't have to specify a
//							SoundInstance ptr to specify a volume.
//
//		07/21/97	JMI	Now handles delete messages.
//
//		08/05/97	JMI	Changed priority to use Z position rather than 2D 
//							projected Y position.
//
//		08/16/97 BRH	Added an arming beep sound and a click sound when the
//							mine is armed.
//
//		08/17/97	JMI	Now, instead of aborting the sample, when the mine arms,
//							it stops the sample's loopage.
//							Now sets the volume every iteration b/c, although the mine
//							stays still, the distance to the local dude varies as the
//							local dude moves.
//							Also, changed m_pthingParent to m_idParent.
//
//		08/28/97 BRH	Added preload function to cache the sounds and images.
