Crushing mode

From ZDoom Wiki

Crushing works differently in Hexen than in the other Doom engine games.

In Doom, when a crusher starts hurting an actor it still continues moving down. For slow crushers this is normally ok. However, this behavior will cause problems with extremely fast crushers that inflict a high amount of damage. Actors can get stuck in such crushers without actually dying.

Hexen changed this behavior so that crushers stop moving once they start hurting something. They only continue their movement if the trapped actor either leaves the sector or dies. This mode ensures that nothing can ever get stuck in a crusher but it also makes it possible that an actor being crushed can move out of the sector.

(development version only)

To expose the different behavior to mappers, all crushing action specials have been extended by a crushmode parameter. This parameter can have 3 values:

• 0: Compatibility: Use the game's default mode (Doom mode for Doom, Heretic and Strife, Hexen mode for Hexen)
• 1: Always use Doom mode
• 2: Always use Hexen mode
