|Making a SIMPLE 3d elevator.|
Written By: Big Al
Look at the example wad called platform.wad.
(sector 4 above).
I assume you already know how to do this.
Split your control sector into 3 sections
Make the floor/ceiling heights in sector 2 to be where
you want the platform to be at its highest point.
Make the floor/ceiling heights in sector 3 to be where
you want the platform to be at its lowest point.
Make the floor/ceiling heights in the sector 1 (sector that controls the floating platform) to be either the same as in sector 2 or the same as in sector 3. Depending if you want the lift to start at the top or bottom. In this case I am starting it at the top so floor = 128 and ceiling = 136.
Tag sector 1 with the next free tag number, in this case 2.
Also put this tag number on your trigger linedefs.
Change the linedef's special flags to be of the "elevator types". In this case I have made linedef 5 type 234 (switch repeat elevator Down next highest level) and linedef 6 type 230 (switch repeat elevator up to next highest level).
That is all there is too it.
