Generic_Crusher

From ZDoom Wiki

205:Generic_Crusher (tag, dspeed, uspeed, silent, crush)
169:Generic_Crusher2 (tag, dspeed, uspeed, silent, crush) (development version only)

tag: Tag of affected sector 
dspeed: How quickly the ceiling lowers 
uspeed: How quickly the ceiling raises 
silent: Set this to 1 to prevent the crusher from making noise 
crush: Amount of damage to apply 

This special encapsulates BOOM's generalized crushers. It is the same as Ceiling_CrushAndRaiseA except that it takes an argument to control the "noisiness" of the crusher.

Unlike the other crushing specials where the crush mode is a parameter, the generic version uses a different special type because it already has all parameters in use. Generic_Crusher uses Doom mode and Generic_Crusher2 uses Hexen mode.
