Linedef type 492, PolyObject – Fade Translucency, is a type of linedef executor which, when triggered, gradually fades the translucency of a specified PolyObject to a specified value.

Setup

This linedef should be given a tag corresponding to the ID of the wanted PolyObject. The translucency is set by the front texture X offset of the control linedef or, if it is 0, the floor height of the control sector. There are 11 possible levels of translucency, ranging from 0 (opaque) to 10 (invisible). If the Lower Unpegged flag is set, the translucency level is specified directly in the front X offset or floor height. Otherwise, it is specified in multiples of 100, as shown by the table below:

Value Translucency
Without Lower Unpegged With Lower Unpegged
0–99, or below 0 0 and below 0% (completely opaque)
100–199 1 10%
200–299 2 20%
300–399 3 30%
400–499 4 40%
500–599 5 50%
600–699 6 60%
700–799 7 70%
800–899 8 80%
900–999 9 90%
1000 and above 10 and above 100% (completely invisible)

Note that although 0 is a legal translucency value, if the front X offset is set to 0, the game will use the control sector floor height instead. In this case, make sure the floor height is also 0.

If the Peg Midtexture flag is set, the supplied translucency value is added to the PolyObject's current translucency instead of replacing it. In this case, negative values can be used to reduce the PolyObject's translucency.

The linedef's front Y offset controls the speed of the fade, where a value 1 corresponds to a fade that is 256 tics long. If the front Y offset is 0 and the control linedef has a back side, the back Y offset is used instead. If the Solid Midtexture flag is set, the Y offset will specify the fade's duration in tics instead. Normally, the fade will not be performed if another fade is still ongoing. If the Repeat Midtexture flag is set, the ongoing fade will be interrupted instead.

If the PolyObject is solid, it will be made intangible at the end of the fade if it is is faded to a higher translucency. If it is faded down again afterwards, it will be made solid again at the start of the fade. This behavior can be disabled by setting the Bouncy Wall flag. If the Slope Skew flag is set, the PolyObject is also made intangible during the fade.

Sample

Example file: ex_ld492_polyobject_fadetranslucency.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:
    1. Save ex_ld492_polyobject_fadetranslucency.wad into the addons folder of your SRB2 directory.
    2. Start SRB2, go to the Addons menu, and then select ex_ld492_polyobject_fadetranslucency.wad.
    3. Start the game in Single Player mode.
    4. 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.
