DDF Lines and Sectors

Line information is stored in either the DDFLINE data lump, or the lines.ddf file. Sector information is stored in the DDFSECT data lump, or the sector.ddf file. Much of the line and sector ddf code is related or identical, so their descriptions are combined in this one section.

These files are used to create and modify map effects, such as doors, elevators, platforms etc.

In both DDFLINE and DDFSECT, each entry consists of a unique mapnumber, enclosed in square brackets, followed by a series of commands to define the properties of the line or sector. These numbers are the ones used in your map editor, and for ease they are often grouped together according to their type.

FLOOR.TYPE and CEILING.TYPEs

MOVE	The floor/ceiling will move to the destination and stop.
MOVEWAITRETURN	The floor/ceiling will move to the destination, wait for PAUSE_TIME then return to it's starting position.
PLAT	The floor/ceiling will move to the destination, wait for PAUSE_TIME then return to it's starting position for PAUSE_TIME before moving again.
STOP	Stops a continuous floor/ceiling from moving.

DEST_REFs

DEST REF	DESCRIPTION
ABSOLUTE	Moves to the exact position specified by DEST_OFFSET.
CEILING	The sector's current ceiling height.
FLOOR	The sector's current floor height.
HISURROUNDINGCEILING	The highest surrounding ceiling height.
HISURROUNDINGFLOOR	The highest surrounding floor.
LOSURROUNDINGCEILING	The lowest surrounding ceiling height.
LOSURROUNDINGFLOOR	The lowest surrounding floor.
LOWESTBOTTOMTEXTURE	Aligns with the shortest bottom texture surrounding.
NEXTLOWESTFLOOR	The floor surrounding that is next lowest.
NEXTHIGHESTFLOOR	The floor surrounding that is next highest.
NEXTLOWESTCEILING	The ceiling surrounding that is next lowest.
NEXTHIGHESTCEILING	The ceiling surrounding that is next highest.

LIGHT_TYPEs

LIGHT TYPE	DESCRIPTION

FLICKER	The light will flicker randomly (like fire).
GLOW	The light will smoothly alternate between light and dark.
SET	The light will be set instantly.
STROBE	Light alternates between light and dark according to LIGHT_BRIGHT_TIME and LIGHT_DARK_TIME.

TELEPORT_SPECIAL

SPECIAL	DESCRIPTION
SAME_HEIGHT	Keep the same floor-relative height that you entered the teleporter with.
SAME_OFFSET	Keep the same centre-of-line-relative offset (between the teleporter line and the landing site).
SAME_SPEED	Keep the original speed that you entered the teleporter with.
ALL_SAME	Just a shorthand for all of the above.
LINE	Line-to-line teleporting (target is a linedef with same tag as the teleport linedef).
FLIPPED	Your direction after teleporting is flipped 180 degrees.
SILENT	No fog, no noise.
RELATIVE	Affects the angle you face after teleporting. It maintains the relative angle difference between the source linedef and the target linedef.

LINE SPECIALS

The following can be used with the SPECIAL commmand in lines.ddf

SPECIAL	DESCRIPTION
MUST_REACH	The Linedef for a switch must be vertically reachable by the player, otherwise it cannot be activated. Only works if you indent the switch in a niche (the engine has no concept of the switch image on the texture).
SWITCH_SEPARATE	The switch will only change the texture on the pushed linedef, and not all the other linedefs with the same tag.

SECTOR SPECIALS

The following can be used with the SPECIAL commmand in sectors.ddf

SPECIAL	DESCRIPTION
AIRLESS	Enables airless mode in this sector. When a player is fully submerged in a sector with this special, the air meter appears in the corner of the HUD, which indicates how much air the player has left.
PROPORTIONAL	Use with WHOLE_REGION, and when you're vertically half-in/half-out of the damaging sector, then damage is only 50%, and so on.
PUSH_ALL	Makes sure **all** objects are pushed, including NOGRAVITY ones.
PUSH_CONSTANT	The push is a constant amount. Good for conveyor belts. Without this flag the push is like a force and things with more MASS will move slower.
SUBMERGED_SFX	When a player is fully submerged in a sector with this special, sounds are muted and muffled to simulate being underwater.
VACUUM_SFX	When a player is in a sector with this special, sounds are muted and muffled to simulate being in a vacuum environment.
REVERB_SFX	When a player is in a sector with this special, sounds are distorted by the custom values we define with REVERB_TYPE, REVERB_DELAY, and REVERB_RATIO.
SWIM	Activates swimming mode when a player is in a sector assigned this special. This allows up and down movement in the sector, plus forward motion in the mlook directon. Jump also works differently. For this to work well, the sector should have a lower GRAVITY than normal and have similar FRICTION and DRAG values. VISCOSITY could also be used.
WHOLE_REGION	Makes damage apply to the whole sector (and not just when you're standing on the floor). Also affects pushing sectors: without this flag the push only happens when the object is touching the floor

EXTRAFLOOR

The following are the different types of extrafloor that can be used.

SPECIAL	DESCRIPTION
BOOMTEX	Use BOOM's texture model (where the real sector's flats are used for the upper part, and the control sector's flats are used for the lower part). Normally the real flats are used for the lowest floor & highest ceiling, and the control flats are used for the extra floor & any ceiling underneath it.
FLOODER	Such an extrafloor will "flood" all vertical regions below it with the same sector properties. Useful for liquids that raise/lower past other extra floors.
LIQUID	Defines a liquid extrafloor, which is not solid and can be passed through (by players, monsters, missiles and other objects). Normally it is thin (just a surface, like the surface of water or lava), but can be used with the THICK keyword too.
SEE_THROUGH	Use this to make a translucent extrafloor (even one that is totally invisible).
SHOOT_THROUGH	Specifies that bullets can pass through this extrafloor. (Always true for when LIQUID is used).
SIDE_UPPER SIDE_LOWER	Extrafloors usually take the side texture from the tagged line of the dummy sector. Instead, this makes it use the upper/lower texture from the line where the extrafloor appears. Useful if the textures on the extrafloor's side need to change often.
THICK	Defines a thick solid extrafloor, which has a top, bottom and sides.
THIN	Defines a thin solid extrafloor - it is just a surface (a single plane, with no sides). This is the default.
WATER	Objects tagged WATERWALKER cannot penetrate extrafloors tagged as WATER. (Can be used to keep creatures like fish under water).
