// input.h
// Project: Postal
//
// History:
//		12/05/96 MJR	Started.
//
//		02/19/97 BRH	Modified to include the keys we are currently using
//							for CDude control in the game.  Added functions for
//							getting and setting input for local and remote play.
//
//		03/03/97	JMI	Added macros for keys 1 through 5 (CDude will use
//							these to chose a weapon).
//
//		03/14/97	JMI	Added macros for space key.
//
//		03/24/97	JMI	Changed typedef for UINPUT from U16 to U32.
//							Added INPUT_ROT_MASK.  The first 9 bits are now reserved
//							for a rotation value between 0 and 359 inclusive.  This
//							pushed all the other bits up a bit, but I don't think that
//							anything currently uses this API w/o the INPUT_* macros.
//
//		03/26/97	JMI	Was getting rotation for mouse input backwards.  Fixed.
//
//		03/27/97	JMI	Added macros for numpad 0 key (CDude will use this for
//							duck).
//
//		03/27/97	JMI	Shortcutted INSERT to same as numpad 0 as patch for now.
//
//		03/31/97	JMI	Now the actual keys used are chosen by g_InputSettings.
//							Therefore, macros are now more generic (e.g., INPUT_R
//							became INPUT_RIGHT, and INPUT_ALT became INPUT_FIRE).
//							Added g_InputSettings declaration.
//
//		04/01/97	JMI	Now we used 10 bits for the rotation value and, although
//							it is stored as unsigned (0..720), it represents a postive
//							or negative delta between -360 and 360.
//
//		04/03/97	JMI	Now checks rspIsBackground() before doing mouse stuff.
//
//		04/11/97 MJR	Moved lots of stuff into input.cpp and added support for
//							recording and playing back inputs for self-playing mode.
//
//		04/11/97	JMI	Changed INPUT_MENU to INPUT_SUICIDE.
//							Also, added INPUT_NEXT_LEVEL.
//							Added an RInputEvent* to GetLocalInput() proto.
//							externs for m_aInputs were not specifying a type and, there-
//							fore, it was an 'int' array instead of UINPUT.
//
//		04/22/97	JMI	Added extern of g_InputSettings.
//
//		04/24/97	JMI	Moved around INPUT_JUMP, INPUT_SUICIDE, and 
//							INPUT_NEXT_LEVEL.
//							Also, added INPUT_WEAPON_6...9 and INPUT_EXECUTE.  
//							Consequently, we're out of inputs (and we still don't have
//							INPUT_TOGGLE_HUMANSHIELD).
//
//		05/02/97	JMI	Increased number of available input bits by reducing
//							the weapon changing bits to 4 bits (now a number instead of
//							bit fields).
//
//		05/13/97	JMI	Changed INPUT_RUN to INPUT_WALK.
//
//		05/14/97	JMI	Added INPUT_PICKUP.
//
//		06/09/97	JMI	Changed INPUT_WALK to INPUT_RUN.
//
//		06/15/97 MJR	Removed INPUT_NEXT_LEVEL, which has now been replaced by
//							an client/server mechanism.
//
//		06/15/97 MJR	Changed to separate InputDemoInit() and InputDemoKill()
//							functions to make it real obvious and clean.
//
//		07/15/97	JMI	Added INPUT_WEAPONS_BIT.
//
//		07/19/97	JMI	Added InitLocalInput().
//
//		07/25/97	JMI	Added more INPUT_*'s and changed INPUT_WEAPON_11,12,13,14
//							to INPUT_CHEAT_11,12,13,14.  There are now 20 possible
//							cheat inputs.
//							Also, removed INPUT_PICKUP.
//
//		08/06/97	JMI	Changed InitLocalInput() to ClearLocalInput().
//
//		08/10/97	JMI	Added StrafeLeft and StrafeRight inputs.
//							Also, changed Jump to Revive and INPUT_JUMP to INPUT_REVIVE.
//							Had put INPUT_JUMP back temporarily b/c I want to check in
//							this and all the files that depend on the new INPUT_REVIVE 
//							in but play.cpp has been checked out for a long time now.
//
//		08/12/97	JMI	Now requires an input event for cheats for GetLocalInput().
//
//		08/17/97	JMI	Got rid of INPUT_JUMP, now play.cpp uses INPUT_REVIVE.
//
//		08/26/97 BRH	Added query function InputIsDemoOver() for the special
//							case ending demo that will be played when the player wins,
//
//		09/06/97 MJR	Added INPUT_IDLE.

// Macros to access bits within an UINPUT type.  There are two types of macros:
// "masks" and "bit numbers".  The masks are designed to set or get the value
// of a bit.  The bit numbers are designed to make it easier to shift the bits
// around.  Note that the bit numbers go from 0 to 'n' (currently 15).
//
// The order of the bits should not be changed without carefully weighing the
// consequences.  It is highly likely that some code will end up relying on the
// order of the bits for efficiency sake, so changing the order of the bits
// could break existing code.  Any such code should certainly refer to these
// macros in some way, so that if it becomes absolutely necessary to change
// this stuff, we can at least track down all the code that uses it.

// The first 10 bits are reserved for a rotation delta value between -359 and 359.
