[@QuasarEE]

Almost as bad in Hexen is the switch case list on mobjtype_t values inside the function to decide what z height to spawn missiles at per thing type. Still not a proper solution (pass it to the function as a parameter, or at least read it out of the firing object's mobjinfo definition).

[@HJkos]

the revenants firing missiles higher most likely because they used to actually visibly "jump" when firing in earlier versions

[@QuasarEE]

They wanted the revenant's missile to spawn higher so that it appeared more closely to be coming from its shoulder cannons. However to do this properly would have required adding a "z" parameter to the function P_SpawnMissile - it normally only takes x, y, and angle in Doom itself. This really wouldn't be a problem at all but I guess John Carmack was feeling lazy, as it would require adding a z parameter to every call to the function. Instead he wrote this gross hack.

[@CarbonRollerCaco]

@@QuasarEE And yet they didn't care that the Cyberdemon was still pissing out his rockets.

[@alfo2804]

@@CarbonRollerCaco I've always assumed they deliberately didn't make the Cyberdemon shoot rockets from its launcher to avoid people cheesing the E2M8 fight. If rockets were spawned from the left side of its sprite, then it would be possible to have a large part of the right side of the demon poke out from one of the pillars while still having the rockets be blocked, allowing the player to get free shots in with no danger of being hit.
