Regular sector types

Back to Sector types

From Matt Fell's Unofficial DOOM Spec the DOOM sector types are:

Dec Hex Class   Description
-------------------------------------------------------------------
 0  00  -       Normal, no special characteristic.
 1  01  Light   random off
 2  02  Light   blink 0.5 second
 3  03  Light   blink 1.0 second
 4  04  Both    -10/20% health AND light blink 0.5 second
 5  05  Damage  -5/10% health
 7  07  Damage  -2/5% health
 8  08  Light   oscillates
 9  09  Secret  a player must stand in this sector to get credit for
                  finding this secret. This is for the SECRETS ratio
                  on inter-level screens.
10  0a  Door    30 seconds after level start, ceiling closes like a door.
11  0b  End     -10/20% health. If a player's health is lowered to less
                  than 11% while standing here, then the level ends! Play
                  proceeds to the next level. If it is a final level
                  (levels 8 in DOOM 1, level 30 in DOOM 2), the game ends!
12  0c  Light   blink 0.5 second, synchronized
13  0d  Light   blink 1.0 second, synchronized
14  0e  Door    300 seconds after level start, ceiling opens like a door.
16  10  Damage  -10/20% health

17  11  Light   flickers on and off randomly

Note that Eternity will not exit the game on an illegal sector type, as was the case with DOOM. The sector type will merely be ignored.
