+// 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.
+// Do not change the MF_NO? flags while a thing is valid.
