	BOOM has added generalized linedef types that permit the parameters of linedef actions to be nearly independently chosen.		BOOM has added generalized linedef types that permit the parameters of linedef actions to be nearly independently chosen. They work as half-way between regular/Boom extended linedef types and [[Detailed parameterized linedef specification\|Eternity parameterized types]]. Unlike the latter, they are meant to be called directly from Doom format maps, without requiring [[ExtraData]] or a more advanced map format, but unlike them, they can only be given a few set values, which in some cases may be insufficient.

	To support these, DETH has been modified to support them via dialogs for each generalized type; each dialog allows the parameters for that type to be independently specified by choice from a array of radio buttons. A parser has also been added to support reading back the function of a generalized linedef ~~from its type number.~~

	~~NOTE to wad authors:~~

	~~This requires a lot of type numbers, 20608 in all so far. Some editors may object to the presence of these new~~ types ~~thru assuming that a lookup table of size 256 suffices (or some other reason)~~. ~~For those that must continue to use such an editor, it may be necessary to stick to~~ the ~~old linedef types~~, ~~which~~ are ~~still present.~~

BOOM has added generalized linedef types that permit the parameters of linedef actions to be nearly independently chosen.

To support these, DETH has been modified to support them via dialogs for each generalized type; each dialog allows the parameters for that type to be independently specified by choice from a array of radio buttons. A parser has also been added to support reading back the function of a generalized linedef from its type number.

NOTE to wad authors:

This requires a lot of type numbers, 20608 in all so far. Some editors may object to the presence of these new types thru assuming that a lookup table of size 256 suffices (or some other reason). For those that must continue to use such an editor, it may be necessary to stick to the old linedef types, which are still present.

We are also providing command line tools to set these linedef types, independent of which editor you happen to use, but they are a lot less slick, and more difficult to use than DETH. See TRIGCALC.EXE and CLED.EXE in the EDITUTIL.ZIP package of the BOOM distribution.

{{backto|Linedef types}}

== Generalized Linedef Ranges =======================================

There are types for Floors, Ceilings, Doors, Locked Doors, Lifts,
Stairs, and Crushers. The allocation of linedef type field numbers is
according to the following table:

Type Start Length (Dec)
-----------------------------------------------------------------
Floors 0x6000 0x2000 (8192)
Ceilings 0x4000 0x2000 (8192)
Doors 0x3c00 0x0400 (1024)
Locked Doors 0x3800 0x0400 (1024)
Lifts 0x3400 0x0400 (1024)
Stairs 0x3000 0x0400 (1024)
Crushers 0x2F80 0x0080 (128)
-----------------------------------------------------------------
Totals: 0x2f80-0x7fff 0x5080 (20608)

======================================================================
The following sections define the placement and meaning of the bit fields within each linedef category. Fields in the description are listed in increasing numeric order.

Some nomenclature:

Target height designations:

H means highest, L means lowest, N means next, F means floor, C means ceiling, n means neighbor, Cr means crush, sT means shortest lower texture.

Texture change designations:

c0n change texture, change sector type to 0, numeric model change
c0t change texture, change sector type to 0, trigger model change
cTn change texture only, numeric model change
cTt change texture only, trigger model change
cSn change texture and sector type to model's, numeric model change
cSt change texture and sector type to model's, trigger model change

A trigger model change uses the sector on the first side of the trigger for its model. A numeric model change looks at the sectors adjoining the tagged sector at the target height, and chooses the one across the lowest numbered two sided line for its model. If no model exists, no change occurs. Note that in DOOM II v1.9, no model meant an illegal sector type was generated.

------------------------------------------------------------------
generalized floors (8192 types)

field description NBits Mask Shift
------------------------------------------------------------------

trigger W1/WR/S1/SR/G1/GR/D1/DR 3 0x0007 0
speed slow/normal/fast/turbo 2 0x0018 3
model trig/numeric -or- nomonst/monst 1 0x0020 5
direct down/up 1 0x0040 6
target HnF/LnF/NnF/LnC/C/sT/24/32 3 0x0380 7
change nochg/zero/txtonly/type 2 0x0c00 10
crush no/yes 1 0x1000 12

DETH Nomenclature:

W1[m] F->HnF DnS [c0t] [Cr]
WR[m] F->LnF DnN [c0n]
S1[m] F->NnF DnF [cTt]
SR[m] F->LnC DnT [cTn]
G1[m] F->C UpS [cSt]
GR[m] FbysT UpN [cSn]
D1[m] Fby24 UpF
DR[m] Fby32 UpT

Notes:

1) When change is nochg, model is 1 when monsters can activate trigger
otherwise monsters cannot activate it.
2) The change fields mean the following:
nochg - means no texture change or type change
zero - means sector type is zeroed, texture copied from model
txtonly - means sector type unchanged, texture copied from model
type - means sector type and floor texture are copied from model
3) down/up specifies the "normal" direction for moving. If the
target specifies motion in the opposite direction, motion is instant.
Otherwise it occurs at speed specified by speed field.
4) Speed is 1/2/4/8 units per tic
5) If change is nonzero then model determines which sector is copied.
If model is 0 its the sector on the first side of the trigger.
if model is 1 (numeric) then the model sector is the sector at
destination height on the opposite side of the lowest numbered
two sided linedef around the tagged sector. If it doesn't exist
no change occurs.

------------------------------------------------------------------
generalized ceilings (8192 types)

field description NBits Mask Shift
------------------------------------------------------------------

trigger W1/WR/S1/SR/G1/GR/D1/DR 3 0x0007 0

WR[m] C->LnC DnN [c0n]
S1[m] C->NnC DnF [cTt]
SR[m] C->HnF DnT [cTn]
G1[m] C->F UpS [cSt]
GR[m] CbysT UpN [cSn]
D1[m] Cby24 UpF
DR[m] Cby32 UpT

Notes:

1) When change is nochg, model is 1 when monsters can activate trigger
otherwise monsters cannot activate it.
2) The change fields mean the following:
nochg - means no texture change or type change
zero - means sector type is zeroed, texture copied from model
txtonly - means sector type unchanged, texture copied from model
type - means sector type and ceiling texture are copied from model
3) down/up specifies the "normal" direction for moving. If the
target specifies motion in the opposite direction, motion is instant.
Otherwise it occurs at speed specified by speed field.
4) Speed is 1/2/4/8 units per tic
5) If change is nonzero then model determines which sector is copied.
If model is 0 its the sector on the first side of the trigger.
if model is 1 (numeric) then the model sector is the sector at
destination height on the opposite side of the lowest numbered
two sided linedef around the tagged sector. If it doesn't exist
no change occurs.

------------------------------------------------------------------
generalized doors (1024 types)

field description NBits Mask Shift
------------------------------------------------------------------

trigger W1/WR/S1/SR/G1/GR/D1/DR 3 0x0007 0
speed slow/normal/fast/turbo 2 0x0018 3
kind odc/o/cdo/c 2 0x0060 5
monster n/y 1 0x0080 7
delay 1/4/9/30 (secs) 2 0x0300 8

DETH Nomenclature:

W1[m] OpnD{1|4|9|30}Cls S
WR[m] Opn N
S1[m] ClsD{1|4|9|30}Opn F
SR[m] Cls T
G1[m]
GR[m]
D1[m]
DR[m]

Notes:

1) The odc (Open, Delay, Close) and cdo (Close, Delay, Open) kinds use
the delay field. The o (Open and Stay) and c (Close and Stay) kinds
do not.
2) The precise delay timings in gametics are: 35/150/300/1050
3) Speed is 2/4/8/16 units per tic

------------------------------------------------------------------
generalized locked doors (1024 types)

field description NBits Mask Shift
------------------------------------------------------------------

trigger W1/WR/S1/SR/G1/GR/D1/DR 3 0x0007 0
speed slow/normal/fast/turbo 2 0x0018 3
kind odc/o 1 0x0020 5
lock any/rc/bc/yc/rs/bs/ys/all 3 0x01c0 6
sk=ck n/y 1 0x0200 9

DETH Nomenclature:

W1[m] OpnD{1|4|9|30}Cls S Any
WR[m] Opn N R{C|S|K}
S1[m] F B{C|S|K}
SR[m] T Y{C|S|K}
G1[m] All{3|6}
GR[m]
D1[m]
DR[m]

Notes:

1) Delay for odc kind is constant at 150 gametics or about 4.333 secs
2) The lock field allows any key to open a door, or a specific key to
open a door, or all keys to open a door.
3) If the sk=ck field is 0 (n) skull and cards are different keys,
otherwise they are treated identically. Hence an "all" type door
requires 3 keys if sk=ck is 1, and 6 keys if sk=ck is 0.
4) Speed is 2/4/8/16 units per tic

-------------------------------------------------------------------
generalized lifts (1024 types)

field description NBits Mask Shift
-------------------------------------------------------------------

trigger W1/WR/S1/SR/G1/GR/D1/DR 3 0x0007 0
speed slow/normal/fast/turbo 2 0x0018 3
monster n/y 1 0x0020 5
delay 1/3/5/10 (secs) 2 0x00c0 6
target LnF/NnF/LnC/LnF<->HnF(perp.) 2 0x0300 8

DETH Nomenclature:

W1[m] Lft F->LnFD{1|3|5|10} S
WR[m] F->NnFD{1|3|5|10} N
S1[m] F->LnCD{1|3|5|10} F
SR[m] HnF<->LnFD{1|3|5|10} T
G1[m]
GR[m]
D1[m]
DR[m]

Notes:

1) The precise delay timings in gametics are: 35/105/165/350
2) Speed is 1/2/4/8 units per tic
3) If the target specified is above starting floor height, or does not
exist the lift does not move when triggered. NnF is Next Lowest
Neighbor Floor.
4) Starting a perpetual lift between lowest and highest neighboring floors
locks out all other actions on the sector, even if it is stopped with
the non-extended stop perpetual floor function.

-------------------------------------------------------------------
generalized stairs (1024 types)

field description NBits Mask Shift
-------------------------------------------------------------------

trigger W1/WR/S1/SR/G1/GR/D1/DR 3 0x0007 0
speed slow/normal/fast/turbo 2 0x0018 3
monster n/y 1 0x0020 5
step 4/8/16/24 2 0x00c0 6
dir dn/up 1 0x0100 8
igntxt n/y 1 0x0200 9

DETH Nomenclature:

W1[m] Stair Dn s4 S [Ign]
WR[m] Up s8 N
S1[m] s16 F
SR[m] s24 T
G1[m]
GR[m]
D1[m]
DR[m]

Notes:

1) Speed is .25/.5/2/4 units per tic
2) If igntxt is 1, then the staircase will not stop building when
a step does not have the same texture as the previous.
3) A retriggerable stairs builds up and down alternately on each
trigger.

-------------------------------------------------------------------
generalized crushers (128 types)

field description NBits Mask Shift
-------------------------------------------------------------------

trigger W1/WR/S1/SR/G1/GR/D1/DR 3 0x0007 0
speed slow/normal/fast/turbo 2 0x0018 3
monster n/y 1 0x0020 5
silent n/y 1 0x0040 6

DETH Nomenclature:

W1[m] Crusher S [Silent]
WR[m] N
S1[m] F
SR[m] T
G1[m]
GR[m]
D1[m]
DR[m]

Notes:

1) Speed is 1/2/4/8 units per second, faster means slower damage as usual.
2) If silent is 1, the crusher is totally quiet, no start/stop sounds
