Lighting linedef types

The lighting linedef types change the lighting in the tagged sector. All are regular or extended types, there are no generalized lighting types. All are switched or walkovers.

Lighting Targets[edit]

  • Lights to Minimum Neighbor
Each tagged sector is set to the minimum light level found in any adjacent sector. The tagged sectors are changed in numerical order, and this may influence the result.
  • Lights to Maximum Neighbor
Each tagged sector is set to the maximum light level found in any adjacent sector. The tagged sectors are changed in numerical order, and this may influence the result.
  • Blinking
Each tagged sector begins blinking between two light levels. The brighter level is the light level in the tagged sector. The darker level is the minimum neighbor light level, or 0 if all neighbor sectors have lighting greater than or equal to the sector's at the time of activation. The blinking is non-synchronous, beginning 1-9 gametics after activation, with a dark period of 1 sec (35 gametics) and a bright period of 1/7 sec (5 gametics).
  • 35 Units
Each tagged sector is set to a light level of 35 units.
  • 255 Units
Each tagged sector is set to a light level of 255 units.
  • Raise by Param
Available with parameterized lines only. Raises tagged sectors' light levels by a given amount.
  • Lower by Param
Available with parameterized lines only. Lowers tagged sectors' light levels by a given amount.
  • Change to Param
Available with parameterized lines only. Changes all tagged sectors' light levels to the given level.
  • Fade
Available with parameterized lines only. Fades all tagged sectors' light levels up or down to the given level.
  • Glow
Available with parameterized lines only. Causes all tagged sectors to fade continuously between two given light levels at a given speed.
  • Flicker
Available with parameterized lines only. Causes all tagged sectors to blink between two given light levels at random. Sector flickering is not synchronized.
  • Strobe
Available with parameterized lines only. Causes all tagged sectors to blink between two given light levels on a period between given minimum and maximum amounts of time. Sector strobing is not synchronized.

Parameterized lighting linedef specials[edit]

Eternity supports the following light level controlling parameterized linedef specials (accessible through ExtraData). If tag is 0, any such parameterized special will affect the sector behind the linedef, if applicable.

  • 368:Light_RaiseByValue(tag, lvl)
Adds the lvl value to the light levels of tagged sectors, capping them to 255.
  • 369:Light_LowerByValue(tag, lvl)
Substracts the lvl value from the light levels of tagged sectors, limiting them to 0.
  • 370:Light_ChangeToValue(tag, lvl)
Sets the lvl value for the light level of tagged sectors, and caps it between 0 and 255 inclusive.
  • 371:Light_Fade(tag, destvalue, tics)
Makes the light level of tagged sectors gradually go to destvalue, for the given amount of tics. tics must be greater than 0.
  • 372:Light_Glow(tag, maxval, minval, tics)
Enables periodic glowing light effect on tagged sectors. tics is the duration between the extreme light levels and must be positive. The sequence starts by fading down.
  • 373:Light_Flicker(tag, maxval, minval)
Enables flickering light effect on tagged sectors.
  • 374:Light_Strobe(tag, maxval, minval, maxtime, mintime)
Enables strobing light effect on tagged sectors. Light will periodically flash, staying at maxval level for maxtime tics and at minval level for mintime tics.
