Linedef type 60, Activate Moving Platform (Adjustable Speed), is a type of linedef special which is used to make floating platforms that move up and down. It is most commonly used in conjunction with linedef type 100, but it can be used to make any type of FOF move vertically. Unlike linedef type 59, the speed of the platform movement can be adjusted.
This linedef requires three control sectors, each of which must be connected to another with at least one linedef. The easiest way to set this up is to make three square sectors together in a row. One of the linedefs on the middle sector should contain the floor over floor linedef special that you want the floating platform to exhibit. This will be the FOF control sector. One of the linedefs in any of these three sectors (it doesn't matter which) should be set to have linedef type 60 and be tagged to the middle sector.
The starting point of the platform is determined by the floor and ceiling height of the middle sector. The top and bottom of the platform's movement are determined by the floor and ceiling heights of the other two control sectors. The floating platform will constantly move, first so that it is equal to the floor and ceiling heights of the lower one of the outer control sectors, then so that it is equal to the floor and ceiling heights of the higher one of the outer control sectors, then the first one again, and so forth. The speed of the platform movement is determined by the length of the control linedef; one fracunit of length equals 0.25 fracunits per tic.
It is possible to add a delay before the platform begins to move, by setting the time in tics in the control linedef's front texture Y offset. If you want the platform 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.
If the Not Climbable flag is checked, the platform will begin moving upwards, rather than downwards.
