To my surprise, they triggered these actions flawlessly. Next, I tried using both a Cacodemon and Lost Soul. At first, I thought this was an issue with floating enemies in general, since an Imp could still trigger the doors and lifts. Odamex's ZDoom 1.22 works, but it appears that at some point, this functionality was altered. The problem I'm encountering is that walkover linedefs for opening doors and lowering lifts aren't being triggered by the Pain Elemental in newer versions of ZDoom and GZDoom. Other monsters usually won't have access to these, so your pet is very crucial to completing each map! For example, a door that can only be opened on one side is only accessible through a monster-only teleporter. The Pain Elemental will be used to open doors and lower lifts that the player cannot reach without the Funny's assistance. Last month, I began making various DeHackEd mods for vanilla DOOM (I play on my DOS PC :D) featuring harmless Pain Elementals, nicknamed 'Funnies.' This morning, I started working on a currently unnamed mod where the player (Doomguy) adopts a funny Pain Elemental and must protect his new pet at all costs. My favorite DOOM enemy is the Pain Elemental because I think they look very adorable.
