// The first argument is the cheat code.
//
// The second argument is its DEH name, or NULL if it's not supported by -deh.
//
// The third argument is a combination of the bitmasks:
// {always, not_dm, not_coop, not_net, not_menu, not_demo, not_deh},
// which excludes the cheat during certain modes of play.
//
// The fourth argument is the handler function.
//
// The fifth argument is passed to the handler function if it's non-negative;
// if negative, then its negative indicates the number of extra characters
// expected after the cheat code, which are passed to the handler function
// via a pointer to a buffer (after folding any letters to lowercase).

// Make every random number generator local to each control-equivalent block.
// Critical for demo sync. Changing the order of this list breaks all previous

// chances of it happening by making each RNG local to a control flow block.
//
// Notes to developers: if you want to reduce your demo sync hassles, follow
// this rule: for each call to P_Random you add, add a new class to the enum
// type below for each block of code which calls P_Random. If two calls to
// P_Random are not in "control-equivalent blocks", i.e. there are any cases
// where one is executed, and the other is not, put them in separate classes.

*
* Equivalent code is available from RSA Data Security, Inc.
* This code has been tested against that, and is equivalent,
* except that you don't need to include two pages of legalese
* with every copy.
*
* To compute the message digest of a chunk of bytes, declare an
* MD5Context structure, pass it to MD5Init, call MD5Update as
* needed on buffers full of bytes, and then call MD5Final, which
* will fill a supplied 16-byte array with the digest.
*
* Changed so as no longer to depend on Colin Plumb's `usual.h'
* header definitions; now uses stuff from dpkg's config.h
* - Ian Jackson <ian@chiark.greenend.org.uk>.
* Still in the public domain.

* DESCRIPTION:
* This file supports conversion of MUS format music in memory
* to MIDI format 1 music in memory.
*
* The primary routine, mmus2mid, converts a block of memory in MUS format
* to an Allegro MIDI structure. This supports playing MUS lumps in a wad
* file with BOOM.
*
* Another routine, Midi2MIDI, converts a block of memory in MIDI format 1 to
* an Allegro MIDI structure. This supports playing MIDI lumps in a wad
* file with BOOM.
*
* For testing purposes, and to make a utility if desired, if the symbol
* STANDALONE is defined by uncommenting the definition below, a main
* routine is compiled that will convert a possibly wildcarded set of MUS
* files to a similarly named set of MIDI files.
*
* Much of the code here is thanks to S. Bacquet's source for QMUS2MID.C

#ifndef __P_MOBJ__
#define __P_MOBJ__
// Basics.
#include "tables.h"
#include "m_fixed.h"
// We need the thinker_t stuff.
#include "d_think.h"
// We need the WAD data structure for Map things,
// from the THINGS lump.
#include "doomdata.h"
// States are tied to finite states are
// tied to animation frames.
// Needs precompiled tables/data structures.
#include "info.h"
//
// NOTES: mobj_t
//
// mobj_ts are used to tell the refresh where to draw an image,
// tell the world simulation when objects are contacted,
// and tell the sound driver how to position a sound.
//
// The refresh uses the next and prev links to follow
// lists of things in sectors as they are being drawn.
// The sprite, frame, and angle elements determine which patch_t
// is used to draw the sprite if it is visible.
// The sprite and frame values are allmost allways set
// from state_t structures.
// The statescr.exe utility generates the states.h and states.c
// files that contain the sprite/frame numbers from the
// statescr.txt source file.
// The xyz origin point represents a point at the bottom middle
// of the sprite (between the feet of a biped).
// This is the default origin position for patch_ts grabbed
// with lumpy.exe.
// A walking creature will have its z equal to the floor
// it is standing on.
//
// The sound code uses the x,y, and subsector fields
// to do stereo positioning of any sound effited by the mobj_t.
//
// The play simulation uses the blocklinks, x,y,z, radius, height
// to determine when mobj_ts are touching each other,
// touching lines in the map, or hit by trace lines (gunshots,
// lines of sight, etc).
// The mobj_t->flags element has various bit flags
// used by the simulation.
//
// Every mobj_t is linked into a single sector
// based on its origin coordinates.
// The subsector_t is found with R_PointInSubsector(x,y),
// and the sector_t can be found with subsector->sector.
// The sector links are only used by the rendering code,
// the play simulation does not care about them at all.
//
// Any mobj_t that needs to be acted upon by something else
// in the play world (block movement, be shot, etc) will also
// need to be linked into the blockmap.
// If the thing has the MF_NOBLOCK flag set, it will not use
// the block links. It can still interact with other things,
// but only as the instigator (missiles will run into other
// things, but nothing can run into a missile).
// Each block in the grid is 128*128 units, and knows about
// every line_t that it contains a piece of, and every
// interactable mobj_t that has its origin contained.
//
// A valid mobj_t is a mobj_t that has the proper subsector_t
// filled in for its xy coordinates and is linked into the
// sector from which the subsector was made, or has the
// MF_NOSECTOR flag set (the subsector_t needs to be valid
// even if MF_NOSECTOR is set), and is linked into a blockmap
// block or has the MF_NOBLOCKMAP flag set.
// Links should only be modified by the P_[Un]SetThingPosition()
// functions.
