Sector specials

21 Light_Phased

22 LightSequenceStart

23 LightSequenceSpecial1

24 LightSequenceSpecial2

In Hexen mode, the sector specials available are:

1 Light_Phasde

2 LightSequenceStart

3 LightSequenceSpecial1

4 LightSequenceSpecial2

These specials deal with phased lighting ("moving lights"). Two different ways to go about doing phased lighting are: automatic, or by-hand. The automatic method is (obviously) more convenient, but the by-hand method is more flexible. Light_Phased is the by-hand special. Place it on a sector, then set the sector's lightlevel to a phase index (0-63). As you place the special on nearby sectors, increment the index for each sector.

Or, to use the LightSequence specials, just place the LightSequenceStart special on a sector. Then, for each additional sector, alternate between LightSequenceSpecial1 & LightSequenceSpecial2. The resulting phased lighting will appear to move toward the sector marked with LightSequenceStart.

For instance, if you wanted phased lighting to flow up a staircase, you could either place Light_Phased on each step, and change the phase index (lightlevel) accordingly. Or, you could place LightSequenceStart on the bottom step (and set that step's lightlevel to something mid-ranged), and then let the game calculate the phase indices for each step by placing the LightSequenceSpecial specials on all other steps. Note that for the LightSequenceSpecial specials to have proper lighting, set their lightlevels to zero, which causes it to use the previous sector's lightlevel. Hence, that "nice value" which was placed on the first step will iterate through all the other steps. If a step's lightlevel is not zero, then that value will filter down to all other steps after it.

26 Stairs_Special1

27 Stairs_Special2

These specials are used by the stair building line specials Stairs_BuildDown, Stairs_BuildUp, Stairs_BuildDownSync, and Stairs_BuildUpSync. The are not used by the Generic_Stairs and Stairs_BuildUpDoom specials, which follow the normal Doom convention for building stairs.

To build stairs using any of the four stair-builders listed above, set the first sector's type to Stairs_Special1. Then alternate between Stairs_Special2 and Stairs_Special1 for the remaining sectors you want in the staircase.

215 Scroll_NorthWest_Fast

216 Scroll_NorthEast_Slow

217 Scroll_NorthEast_Medium

218 Scroll_NorthEast_Fast

220 Scroll_SouthEast_Medium

221 Scroll_SouthEast_Fast

222 Scroll_SouthWest_Slow

223 Scroll_SouthWest_Medium

224 Scroll_SouthWest_Fast

These specials scroll the sector's floor in the diraction and speed indicated and also carry anything on it in the same direction. These are intended mainly for compatibility with Hexen levels because they also exhibit the odd Hexen behavior of carrying things faster than they scroll the floor.
