// Project: Postal
//
// This module implements the CCharacter class which is the class of generic
// character functionality for game characters.
//
// History:
//
//		03/03/97	BRH,JMI	Started this generic character object to reduce the
//							amount of redundant code.
//
//		03/04/97	JMI	Changed calling convention and naming for velocities and
//							position functions and added a Deluxe updater.
//
//		03/04/97	JMI	The m_sprite.m_sInFlags are now only initialized in 
//							Startup() (instead of in Render()).  If it was in Render(),
//							it overwrites any other initializations that take place on
//							these bit flags (such as XRay).
//
//		03/04/97	JMI	UpdateVelocities() now makes sure the delta value is cor-
//							rect even when m_dVel is capped or trimmed.
//							Drags are now added (was subtracting them).
//							Commented out code to restore old velocities (as if accel
//							did not take place) when no new position was obtained.
//
//		03/04/97	JMI	Added support for messages.
//
//		03/05/97	JMI	Converted all rspMod360() calls to new calling convention.
//							Added fire response in OnBurnMsg().
//							Added UpdateFirePosition().
//
//		03/05/97	JMI	Added PrepareWeapon() and ShootWeapon() that can handle
//							any current CThing weapon (i.e., cannot handle bullets).
//
//		03/05/97 BRH	Added code to WhileShot, WhileBurning, WhileBlownUp,
//							WhileDying for default functionality for most of the
//							victims and enemy guys.
//
//		03/05/97	JMI	Now OnDead() draws current animation frame into the back-
//							ground.
//
//		03/05/97	JMI	Added handler for suicide message.
//							WhileBlownUp() now stops all horizontal movement when the
//							character encounters the 'no walk' attrib.
//							Added UpdateVelocity() inline in attempt to unify the way
//							velocity is updated.  Works for two of three cases, haven't
//							tried third for fear of hosedness.
//							Currently vertical tolerance is not considered in
//							ValidatePosition().
//							Made external horizontal drag in OnExplosionMsg() negative.
//
//		03/06/97	JMI	Re-enabled vertical tolerance utilizing new m_bAboveTerrain
//							boolean.
//
//		03/06/97	JMI	Increased horizontal surface drag.
//							Now Render() uses the combined attributes for the layer.
//
//		03/06/97	JMI	No longer relies on m_pWeapon to store weapon ptr.  But,
//							if a derived class sets m_pWeapon to point to a weapon,
//							Render() will still update its transform.
//							This should be removed as soon as no one uses m_pWeapon.
//
//		03/06/97	JMI	Now, if EditRect() does not have enough info to create
//							a rectangle, it tries a couple ways.
//
//		03/06/97	JMI	Now ShootWeapon() gets the rigid body transform from the
//							current animation instead of from the child's sprite.
//
//		03/06/97	JMI	Now allows a character to fall off of things but not onto
//							unless the height difference is within tolerance.
//
//		03/06/97	JMI	Added a GetAttributes() function.
//							Now uses GetAttributes() instead of manually doing it.
//
//		03/12/97	JMI	Actually, mistakenly, last time I put GetAttributes() in
//							WhileBlowingUp() instead of in DeluxeUpdatePosition().
//							Now DeluxeUpdatePosition() utilizes GetAttributes().
//							DeluxeUpdatePosition() now takes the duration in seconds
//							as a parameter instead of calculating it itself (and over-
//							writing m_lPrevTime).
//
//		03/13/97	JMI	GetAttributes() was combining ONLY the layer bits.  What
//							I really wanted it to do was combine all but the height
//							bits.  Now it uses ~ATTRIBUTE_HEIGHT_MASK to combined the
//							bits.
//
//		03/13/97	JMI	Load now takes a version number.
//
//		03/17/97	JMI	Now most of CCharacter's functionality is implemented in
//							its base class, CThing3d.
//
//		03/21/97	JMI	Removed m_pWeapon.
//
//		03/21/97	JMI	ShootWeapon() now sets the rotation of the weapon beforing
//							detaching it.
//
//		03/21/97	JMI	ShootWeapon() now returns a ptr to the weapon.
//
//		04/02/97	JMI	OnDead() now destroys any weapon the character still has.
//							The idea is that, if the weapon was just rendered as a 
//							child object onto the background, it should no longer exist
//							in CThing form.  Also, undeleted child weapons will clutter
//							memory until the realm they're in is destroyed.
//							Removed m_pCurrentAnim.
//
//		04/02/97	JMI	PrepareWeapon() now, also, returns a ptr to the weapon.
//
//		04/15/97 BRH	We were noticing that the guys no longer turned dark after
//							being burnt.  I added the change to m_sBrightness in
//							WhileBurning() so that he turns dark when dead.
//
//		04/23/97	JMI	Added IsPathClear(), a rather deluxe function.
//
//		04/24/97	JMI	#if 0'd out the debug portion of IsPathClear() which 
//							displayed the check path as red or green line depending on
//							whether or not the path was entirely clear.
//
//		04/25/97	JMI	Broke blood pool creation out of MakeBloody() and into
//							MakeBloodPool().
//
//		04/28/97 BRH	Changed PrepareWeapon to use the new fake class ID's to
//							identify weapons that don't have an object associated with
//							them like guns.  Now this function is generic enough that
//							the CDude doesn't have to override its own version of
//							PrepareWeapon.
//
//		04/28/97	JMI	Changed ShootWeapon() to work for CShotGunID, CPistolID, 
//							CMachineGunID, and CFireballID.
//							Also, added FireBullets() to simplify firing of bullets.
//
//		04/29/97	JMI	Added case to ShootWeapon() to handle mines.
//
//		04/29/97	JMI	Changed references to child weapon's m_sprite to 
//							GetSprite() calls and took out special cases for
//							CFireballID and CMineID.
//
//		05/02/97	JMI	FireBullets() now returns type bool indicating whether or
//							not someone/thing was hit by the bullets.
//
//		05/02/97	JMI	Added timer explicitly for CCharacter::While/On* functions.
//							Utilized the timer in WhileBurning() to make sure dude dies
//							within a certain amount of burning and to make the dude
//							darken while he burns instead of just at the end.
//
//		05/13/97	JMI	Now MakeBloody() creates chunks based on the passed damage.
//
//		05/14/97	JMI	Now Render() uses PositionChild() to position the weapon.
//
//		05/16/97	JMI	Added directionality to blood.
//
//		05/22/97	JMI	Added bullet casings and shells.
//							Also, made all particle effects (Blood, Casings, and 
//							Shells) obey g_GameSettings.m_sParticleEffects.
//
//		05/23/97	JMI	Lowered velocity of shells and casings generated by Fire-
//							Bullets().
//
//		05/26/97	JMI	Lowered vertical velocity of shells and casing generated
//							by FireBullets().
//
//		05/26/97 BRH	Added CAssaultWeapon which is just the shot gun allowed
//							to rapid fire.
//
//		05/29/97	JMI	Removed references to m_pRealm->m_pAttribMap which no longer
//							exists.
//
//		05/30/97	JMI	Changed FireBullets() to only play the sample once (through
//							FireDeluxe(...) ).
//
//		06/02/97	JMI	Added an WhileOnLadder().
//
//		06/02/97	JMI	Removed ladder stuff.
//
//		06/05/97	JMI	Changed m_sHitPoints to m_stockpile.m_sHitPoints to 
//							accommodate new m_stockpile in base class, CThing3d (which
//							used to contain the m_sHitPoints).
//
//		06/08/97 BRH	Added IlluminateTarget() function to check for targets within
//							a cone in the direction you specify.  This will be used by the
//							CDude for targeting feedback.  He will use it to place a
//							target sprite on the target he is aiming at.
//
//		06/10/97	JMI	Removed CSmash::Misc from the default bits to collide with
//							when using FireBullets().
//
//		06/11/97 BRH	Added passing of Shooter ID down into the Shot message and
//							to the other weapons in ShootWeapon().  Also added the
//							bullets damage chart to give tunability to different
//							weapons and target vs shooter differences.	
//
//		06/11/97	JMI	Added Preload() for loading assets used during play.
//
//		06/11/97 BRH	Added the ID of the killer and used that to report to
//							the score module at time of death.
//
//		06/12/97	JMI	3D weapons are now initially (in PrepareWeapon() ) set to
//							CWeapon::State_Hide.
//
//		06/13/97	JMI	Added WhileHoldingWeapon().
//
//		06/15/97	JMI	Now OnShotMsg() checks to make sure we're receiving damage
//							before calling MakeBloody() (if someone's wearing a kevlar
//							vest, they may receive the impact forces of the bullet but
//							little or no damage).
//
//		06/17/97	JMI	Converted all occurrences of rand() to GetRand() and
//							srand() to SeedRand().
//
//		06/24/97	JMI	Now intializes animthing's m_msg's priority to 0 on in 
//							MakeBloodPool() so we don't end up with randomly 
//							prioritized messages.
//
//		06/30/97	JMI	Now uses CRealm's new GetRealmWidth() and *Height()
//							for dimensions of realm's X/Z plane.
//
//		07/01/97	JMI	Now passes rigid body transform to PositionChild().
//
//		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.
//
//		07/21/97	JMI	Now has an Update() which updates the weapon's position.
//							Also, added ValidateWeaponPosition().
//
//		07/21/97	JMI	Now ValidateWeaponPosition() checks to make sure the weapon
//							state is not State_Hide before checking the position.
//
//		07/27/97	JMI	No longer calls CRealm::Make2dResPath() on res names
//							given to CAnimThing as it already does that 
//							automatically.
//							Also, now appropriately places blood splats on outside of 
//							character's body based on opposite angle of impact.
//
//		07/30/97	JMI	Now copies necessary ammo from ccharacter's stockpile to
//							the ammo, if required.
//
//		08/02/97 BRH	Added virtual OnHelpMsg function.
//
//		08/07/97	JMI	Added ShootWeapon()/FireBullets() support for the double
//							barrel.
//
//		08/07/97	JMI	Now blood splat lands on ground (at terrrain height) 
//							instead of at the character's Y.
//							Changed RAND_SWAY to an inline that considers the scene 
//							scale.
//
//		08/07/97	JMI	In last version did not put the blood pool on the ground
//							while animating.
//
//		08/08/97	JMI	Now this class plays the flamer sound and handles its
//							loopage.
//
//		08/08/97	JMI	Upgraded PrepareWeapon(), ShootWeapon(), and FireBullets()
//							to handle AutoRifle, Uzi, and SmallPistol.
//
//		08/09/97	JMI	Now MakeBloody() tries to keep shots low for characters
//							that are in the writhing state.
//
//		08/09/97	JMI	Converted a use of TransformPtsToRealm() to GetLinkPoint().
//
//		08/11/97	JMI	Changed DoubleBarrel sound to g_smidDeathWadLaunch (was the
//							ol' wimpy g_smidShotGun).
//
//		08/13/97	JMI	Temporarily shows particle effects regardless of user
//							setting in multiplayer mode.
//
//		08/17/97	JMI	Now FireBullets() will never shoot writhers.
//
//		08/17/97	JMI	Changed m_pthingParent to m_idParent.
//
//		08/18/97	JMI	Now applies no randomization to CChunks and instead allows
//							CChunk::Setup() to apply its own randomization based on
//							sway values passed to it.  Also, CChunk::Construct() will
//							now fail if particles are disabled so we don't need to
//							check for that anymore.
//
//		08/18/97	JMI	FireBullets() now includes the random variation in angle
//							in the bullet message (before it used the UNswayed angle).
//
//		08/18/97	JMI	Changed OnDead() to call DeadRender3D() (which used to be
//							known/called as just another Render() overload).
//
//		08/24/97	JMI	Adjusted shotgun pellets to be 8 when shot by a dude into
//							a non dude.  Also, adjusted machine gun bullets to be 15
//							when shot by a dude into a non dude.
//
//		08/28/97 BRH	Added a virtual put me down message handler.
