Linedef type 53
Linedef type 53, Continuous Floor/Ceiling Mover, is a type of linedef special which moves the floor and ceiling of a sector or an FOF vertically back and forth between specified heights. It is useful as an alternative for moving platforms made with linedef type 59 or linedef type 60, as its change of direction is faster. It can also be used to make simple elevators and FOF crushers.
Note that in UDMF, this effect merges the parameters from linedef type 53-55.
Binary Setup
To use this effect, create two control sectors outside of your map, joined by a single linedef. The easiest way to do this is to create two small squares of equal size which share a linedef. The linedef which joins together the two control sectors should be set to have linedef type 53, and be tagged to the desired target sector(s) within the map or FOF control sector(s).
The target sector's/FOF's floor and ceiling will first move to the floor and ceiling heights of the linedef's front control sector, then to the floor and ceiling heights of the linedef's back control sector, then to the front sector again, and so on. The length of the control linedef determines the speed of the movement; one fracunit of length equals 0.25 fracunits per tic.
It is possible to add a delay before the floor and ceiling begin to move, by setting the time in tics in the control linedef's front texture Y offset. If you want the ceiling and floor to delay every time before changing direction, you can do so by setting the time in tics in the control linedef's front texture X offset.
Be aware that while using this action that if the floor and ceiling are moving too fast and are too close to each other that the sector will brake and start to distort itself. This is mainly noticeable with small FOFs.

UDMF Setup
To use this effect, create two control sectors outside of your map, joined by a single linedef. The easiest way to do this is to create two small squares of equal size which share a linedef. The linedef which joins together the two control sectors should be set to have linedef type 53, and Argument 1 should be tagged to the desired target sector(s) within the map or FOF control sector(s).
Argument 2 determines whether the Floor, Ceiling or Both planes will be affected by the movement.
The target sector's/FOF's floor and ceiling will first move to the floor and ceiling heights of the linedef's front control sector, then to the floor and ceiling heights of the linedef's back control sector, then to the front sector again, and so on. Argument 3 and Argument 4 determines the foward and return speed of the movement, respectively; in one fracunits per tic.
It is possible to add a delay before the floor and ceiling begin to move, by setting the time in tics in Argument 5. If you want the ceiling and floor to delay every time before changing direction, you can do so by setting the time in tics in Argument 6.
Be aware that while using this action that if the floor and ceiling are moving too fast and are too close to each other that the sector will brake and start to distort itself. This is mainly noticeable with small FOFs.
