Editing Generalized sector types

Eternity provides generalized sector types, based on bit fields, that allow several sector type properties to be independently specified for a sector. Texture change linedefs can be used to switch some or all of these properties dynamically, outside lighting.

{{Backto|Sector types}}

'''For classic non-UDMF format only''': Bits 0 to 4 specify the lighting type in the sector, the same codes that DOOM used are employed:

 Dec Bits 4-0   Description
 -------------------------------------------------------------------
 0   00000      Normal lighting
 1   00001      random off
 2   00010      blink 0.5 second
 3   00011      blink 1.0 second
 4   00100      -10/20% health AND light blink 0.5 second
 8   01000      light oscillates
 12  01100      blink 0.5 second, synchronized
 13  01101      blink 1.0 second, synchronized
 17  10001      flickers on and off randomly

'''For UDMF''': bits 0 to 7 are the same as in [[Regular sector types]], the UDMF section.

'''IMPORTANT for UDMF''': to use the following values in UDMF, you need to multiply them by 8 first. The components from 0 to 255 apply te

All decimal values listed below can be added from each category to obtain the generalized sector effects.

Bits 5 and 6 set the damage type of the sector, with the usual 5/10/20 damage units per second.

 Dec  UDMF dec  Bits 6-5 / 9-8   Description
 -------------------------------------------------------------------
 0    0         00               No damage
 32   256       01               5  units damage per sec (halve damage in TYTD skill)
 64   512       10               10 units damage per sec
 96   768       11               20 units damage per sec
Bit 7 makes the sector count towards the secrets total at game end

 Dec  UDMF dec  Bit 7 / 10    Description
 -------------------------------------------------------------------
 0    0          0            Sector is not secret
 128  1024       1            Sector is secret
Bit 8 enables the ice/mud effect controlled by linedef 223

 Dec  UDMF dec  Bit 8 / 11    Description
 -------------------------------------------------------------------
 0    0          0            Sector friction disabled
 256  2048       1            Sector friction enabled
Bit 9 enables the wind effects controlled by linedefs 224-226

 Dec  UDMF dec  Bit 9 / 12    Description
 -------------------------------------------------------------------
 0    0          0            Sector wind disabled
 512  4096       1            Sector wind enabled
== Introduced with SMMU ==

Bits 10 and 11 are now implemented as of SMMU v3.21.
Bit 10 suppresses all sounds within the sector, while Bit 11 disables any sounds due to floor or ceiling motion by the sector. Bit 11 is especially useful in silencing constructs such as pseudo-3D bridges, which give off an undesirable plat sound when they move.

 Dec   UDMF dec  Bit 10 / 13  Description
 -------------------------------------------------------------------
 0     0          0           Sounds made in sector function normally
 1024  8192       1           Sounds made in sector are suppressed

 Dec   UDMF dec  Bit 11 / 14  Description
 -------------------------------------------------------------------
 0     0          0           Sounds made by sector floor/ceiling movement normal
 2048  16384      1           Sounds made by sector floor/ceiling movement suppressed

== Introduced with MBF21 ==
These new bits are added since the MBF21 editing standard.

===Instant death sector===
A new bit is added in MBF21, bit 12 under classic format and bit 15 under UDMF. When this bit is set, bits 5-6 (classic) or 8-9 (UDMF) change their meaning from "sector damage" to different variations of this instant death sector type, as shown in the following table:

|-
||4096||1000||32768||8000||Player dies instantly when on sector floor (unless wearing radiation suit or invulnerability)

|-
||4160||1040||33280||8200||Kill all players and exit to next level (useful for forcing pistol start)
