More suggestions of mine!:
- A wall version of the Culling Plane.
- An action that runs a script when called, similar to Linedef Type 415.
- An action that goes to a set state when certain player control buttons are being pressed at the time; i.e, if the required player control buttons in Var 1 are being used (e.g, spin, jump, ring fire, etc), the object calling the action will go to the state set in Var 2.
