Linedef type 428

An example of activating two platforms with different speeds.

Linedef type 428, Start Platform Movement, is a type of linedef executor which, when triggered, makes a tagged FOF move. It essentially does the same thing as linedef type 60, the difference being that the latter invariably executes on level load, whereas this linedef type can be activated by any desired executor trigger.

Setup

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 428, and be tagged to the middle sector. The same sector should also have the trigger linedef.

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 Flag [6] / Not Climbable is checked, the platform will begin moving upwards, rather than downwards.
