Crushing ceiling linedef types

From Eternity Wiki
Jump to: navigation, search

A crusher ceiling is a linedef type that causes the ceiling to cycle between its starting height and 8 above the floor, damaging monsters and players that happen to be in between. Barrels explode when crushed.

Once a crusher ceiling is started it remains running for the remainder of the level even if temporarily suspended with a stop type. No other ceiling action can be used in that sector thereafter.

Varieties of Crushers[edit]

A crusher can be activated by pushing on a linedef bounding it (generalized types only), or by pushing on a switch with the same tag as the crusher sector, or by walking over a linedef with the same tag as the crusher, or by shooting a linedef with the same tag as the crusher with an impact weapon (generalized types only).

A crusher has a speed: slow, normal, fast, or turbo. The slower the speed, the more damage the crusher does when crushing, simply thru being applied longer. When a slow or normal crusher is moving down and encounters something to crush, it slows down even more, by a factor of 8. This persists until it reaches bottom of stroke and starts up again. Fast and turbo crushers do not slow down.

A crusher can be silent. The regular silent crusher makes platform stop and start noises at top and bottom of stroke. The generalized silent crusher is completely quiet.

A crusher linedef is provided to stop a crusher in its current position. Care should be used that this doesn't lock the player out of an area of the wad if the crusher is too low to pass. A crusher can be restarted, but not changed, with any crusher linedef.
