Linedef type 430

Linedef type 430, Crush Floor Once, is a type of linedef executor which, when triggered, makes the floor of every tagged sector move up to the ceiling once, and then back down again to a specified position. If players are caught above the sector when it crushes, they will be killed instantly. This is useful for making highly specialized floor-to-ceiling crushers (or regular crushers in reverse gravity) which only activate when a player is standing above them, or when some other event occurs.

Setup

The control linedef should be tagged directly to the specified target sector. Additionally, you have to set the control sector's floor height to specify the height which the crusher retracts to. The speed of the crusher is determined by the X distance of the control linedef; one fracunit equals 0.25 fracunits/tic.

Sample

Example file: ex_ld430_crushflooronce.wad (MAP01)

Pressing the red button will activate the crusher.

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_ld430_crushflooronce.wad` into the `addons` folder of your SRB2 directory. Start SRB2, go to the Addons menu, and then select `ex_ld430_crushflooronce.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.
