A translucent, intangible from bottom, crumbling FOF.
Linedef type 174, Crumbling, Respawn, Intangible from Bottom, Translucent, is a type of translucent floor over floor platform which will crumble and fall one second after being jumped or stepped upon by a player. 15 seconds after crumbling, it will reappear at its original location. This FOF can be jumped through from below, but is solid to anything landing on it from above. This FOF is useful for situations in which the player needs easy access to platforms from below, but needs to keep moving continuously.
Setup
The flats, floor height, and ceiling height of the FOF are determined by the flats, floor height, and ceiling height of the control sector, and the sidedefs of the FOF's walls are determined by the sidedef of the control linedef.
The alpha value of this FOF's translucency can be changed by setting the control linedef's front side upper texture to the number symbol (#), followed by a three-digit decimal number, from 000 to 255. #000 is completely invisible, and #255 is completely opaque. Note that in the Software renderer, there are actually only eleven different distinct values: #000–#011, #012–#037, #038–#063, #064–#088, #089–#114, #115–#139, #140–#165, #166–#191, #192–#216, #217–#242, #243–#255, where #000–#011 is invisible, and #243–#255 is opaque. The advantage of using the completely opaque values is the ability to properly render flats which contain transparent pixels. If no value is set in the front side upper texture, however, the default alpha value of #128 will be used.
If Flag [6] / Not Climbable is checked, the FOF will not cast a shadow.
