Ceiling_CrushStop
From ZDoom Wiki
44:Ceiling_CrushStop (tag)
tag: Tag of affected sector
Usage
Stops a crushing ceiling.
This special works on Ceiling_CrushAndRaise, Ceiling_CrushAndRaiseA and Ceiling_CrushAndRaiseSilentA. However, once the ceiling is stopped after one of these specials, using a special to make it crush again will resume the type of crushing it was doing previously. It is also worth noting that ZDoom stores the ceiling's normal height and its current crushing height seperately, so stopping a crusher then attempting to use another special to lower or raise the ceiling will not work.
Examples
As the ceiling specials are fairly trivial, examples of every one can be found in the example wad, Squash. This wad runs on Map01 of Doom2.
