// Project: Postal
//
// This module implements the CFirebomb weapon class which is a hand
// thrown grenade weapon that explodes into a ring of fire..
// 
//
// History:
//		01/17/97 BRH	Started this weapon object.
//
//		02/04/97	JMI	Changed LoadDib() call to Load() (which now supports
//							loading of DIBs).
//
//		02/11/97 BRH	Started the firebomb object from the grenade file
//
//		02/14/97 BRH	Now uses resource manager to get the image.
//
//		02/19/97 BRH	Changed the main part of the weapon to 3D and left
//							the fire fragments as 2D.  Also added some randomness
//							to the pattern and increased the burn times.
//
//		02/19/97 BRH	Added ProcessMessages function to check for 
//							ObjectDeleted messages.
//
//		02/21/97 BRH	Changed fragments to be invisible controllers of the
//							small fire animation rather than an 2d sprite.  This
//							sort of hides the bounce effect which is bad so we may
//							want to put it back.  Also uses the small fire for
//							the fire fragments.
//
//		02/23/97 BRH	Changed the coordinate system to x,-z
//
//		02/23/97 BRH	Added a static Preload() function which will be called 
//							before play begins to cache the resources needed for this
//							object.
//
//		02/24/97	JMI	No longer sets the m_type member of the m_sprite b/c it
//							is set by m_sprite's constructor.
//
//		02/24/97 BRH	Changed to using reality.h motion templates.  Using new
//							algorithm for detecting ground and walls.  Made the 
//							center fire more than 1 sprite and changed to thin
//							fire.  Added sound effect for initial impact.
//
//		02/28/97 BRH	Derived this from the CWeapon base class.
//
//		03/03/97	JMI	Changed reference to CGrenade::State_Deleted to 
//							CWeapon::State_Deleted.
//
//		03/06/97 BRH	Changed to using ID's for keeping track of the file
//							and gettting the pointer from the ID each time.
//
//		03/13/97	JMI	Load()s now take a version number.
//
//		03/21/97 BRH	Changed this to ignore ATTRIBUTE_NOT_WALKABLE so that
//							the cocktails won't bounce off of the edge of the world.
//
//		04/10/97 BRH	Updated this to work with the new multi layer attribute
//							maps.
//
//		05/04/97 BRH	Took out an old unused reference to an STL iterator.
//
//		05/13/97	JMI	CFireBomb was using a formula to compute the direction of
//							8 firefrags such that one appeared in a random position
//							in all of 8 octants.  The problem was the formula subtract-
//							ed 25 which, in the case of the first octant, if the random
//							position 24 or less were chosen, would result in a negative
//							value.  But, to simply remove this could cause values 360
//							or over since the random portion was based on 50.0 and not
//							the size of an octant.  So I removed the -25 and changed the
//							50.0 to (360/8) which, as far as I can tell, makes the 
//							inclusive extents of the formula [0..359].
//
//		05/29/97	JMI	Removed ASSERT on m_pRealm->m_pAttribMap which no longer
//							exists.
//
//		06/03/97 BRH	Changed the cocktails so they don't bounce off of 
//							walls, they just fall to the ground and break.
//
//		06/11/97 BRH	Added shooter ID passing to the fires that it creates.
//
//		06/12/97	JMI	Now handles State_Hide by setting m_sprite's InHidden flag.
//
//		06/12/97 BRH	Fixed order of passing the shooter ID.
//
//		06/16/97 BRH	Fixed starting condition in not walkable area.
//
//		06/18/97 BRH	Changed over to using GetRandom()
//
//		06/25/97 BRH	Added use of base class 2D shadow on the ground, but loaded
//							a smaller shadow resource.
//
//		06/30/97 BRH	Added cache of sound effects in 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.
//
//		07/27/97	JMI	Changed to use Z position (i.e., X/Z plane) instead of
//							Y2 position (i.e., viewing plane) position for draw 
//							priority.
//
//		07/30/97	JMI	Same old delete error showed up on Alpha.  
//							ProcessMessages() was deleting the firebomb on a delete msg
//							but, once returned to Update(), it was checking the 
//							m_eState member to see if it should return.  Unfortunately,
//							since 'this' had already been deallocated, it was too late
//							to do such a thing.
//
//		08/17/97	JMI	Changed m_pthingParent to m_idParent.
//
//		08/20/97 BRH	Moved firebomb sound to Destruction volume control.
//
//		08/27/97 BRH	Added large fire sound which had not been used until now.
//
//		08/28/97	JMI	Added a explode counter so we can cap the number of 
//							explosions a firefrag can make.
//
//		08/28/97 BRH	Added cache of large fire sound.
