ForceField

Turns the line into a forcefield that will hurt (8 damage on SKILL_VERY_EASY, 16 on all other) and push the player when activating. It does not block the player, you have to set the blocking flags on the map. Note that you will have to set it “repeatable” to make the force field persistent and you have to set the proper activation type.

33:ForceField (No parameters required)

This special can be cleared by the A_RemoveForceField codepointer. In Strife levels with forcefields, a ForceFieldGuard actor is always placed in a sector bordering the forcefield linedef so that the explosion of a DegninOre will destroy it and trigger the removal of the force field effect even if the ore was placed within range but outside of the sector.
