Linedef type 429

An example of using a linedef 429.

Linedef type 429, Crush Ceiling Once, is a type of linedef executor which, when triggered, makes the ceiling of every tagged sector move down to the floor once, and then back up again to its original position at half the speed. If players are caught beneath the sector when it crushes, they will be killed instantly. This effect is useful for making highly specialized crushers which only activate when a player is standing under them, or when some other event occurs.

Setup

The control linedef should be tagged directly to the specified target sector. The speed of the crusher is determined by the length of the control linedef; one fracunit equals 0.125 fracunits per tic.

Checking Flag [9] / Solid Midtexture / Effect 4 makes the crusher move at twice the provided speed, keeping a constant speed while crushing or retracting. With this flag checked, the speed is determined by the linedef X distance.
