Linedef type 417

Linedef type 417, Start Adjustable Pulsating Light, is a type of linedef executor which, when triggered, starts a pulsating light effect in every tagged sector, in the same manner as linedef type 602.

Setup

The control linedef's length determines the speed of the pulsating light, in relation to the two brightnesses specified. Four fracunits of length mean that the light level will change by one unit per tic, so the longer the linedef, the quicker the speed. The default speed is 32 fracunits (or 8 units of light level per tic). Both the control sector's and the target sector's brightness levels affect the brightness at which the light pulsates. The lesser brightness level between the two determines the minimum light level for this effect, while the greater brightness level determines the maximum. The difference between the two brightness levels is also a factor in how quickly the light pulsates. The smaller the difference is, the quicker the light will pulsate, even if the pulsating speed set by the control linedef remains the same.

If you use a two-sided linedef with Flag [6] / Not Climbable checked, the light level of the linedef's back sector will be used as the second light level, instead of the target sector, allowing you to set the latter at a different starting light level entirely.

Note
In the Software renderer, the brightness levels can also determine how smoothly the light pulsates. Also note that, since the Software renderer only has 32 distinct light levels, the pulsating effect may not be visible if the chosen light levels are too close together.

Sample

Example file: ex_ld417_startadjustableglowinglight.wad (MAP01)

How to use
You may load this file into your favorite map editor, such as Zone Builder. Select `MAP01` as the map to load. You may also load this file in the game: Save `ex_ld417_startadjustableglowinglight.wad` into the `addons` folder of your SRB2 directory. Start SRB2, go to the Addons menu, and then select `ex_ld417_startadjustableglowinglight.wad`. Start the game in Single Player mode. Press the Console button (`~`), and type in the command `MAP MAP01` to access the example map. When you load this file in the game, it replaces Greenflower Zone Act 1.
