EVENT_CHECKFLOORDAMAGE is a Game Event.

This event is triggered whenever the player is standing on a floor that isn't a sprite bridge. (i.e. in P_CheckFloorDamage()).

RETURN is set to the picnum of the floor the player is standing on.

If RETURN is set to -1, hardcoded effects (excluding tile 4240, i.e. PURPLELAVA) that damaging floors would normally cause are cancelled.

By setting RETURN to one of the following numbers, it is possible to make other floor sprites exhibit the same damaging properties as the corresponding hardcoded tiles:

• 200 (FLOORSLIME) - 6.25% chance each tic of 1-4 damage. Causes a green screen overlay when taking damage as well as pain sounds. (DUKE_LONGTERM_PAIN)
• 859 (HURTRAIL) - 12.5% chance each tic of 1-4 damage. Causes a white screen overlay accompanied by electrical noises and pain sounds. (SHORT_CIRCUIT & DUKE_LONGTERM_PAIN). Note that it is not possible to prevent or replicate the effect that takes all player weapons away if player starts on this picnum.
• 1082 (FLOORPLASMA) - 6.25% chance each tic of 1-4 damage. Causes a reddish-orange screen overlay when taking damage as well as pain sounds. (DUKE_LONGTERM_PAIN)

The purple lava tile is not included, as this floor type damages the player while in the air as well.

Note that setting the damaging floor property also makes the player use his boots inventory item as protection. Setting RETURN to -1 causes the player not to use up any boots.
