There is already
an option to disable multiplayer-specific
weapons in multiplayer:
Code: Select all
sv_noweaponspawn (boolean)
Default: false
If true, weapons that are flagged to appear only in multiplayer are not spawned when playing in cooperative mode.
Making a similar option that applies to other items that spawn around the map—such as ammunition, health pickups, and even barrels (such as in E1M1, where they cover up an armor pickup in the corner of the room)—would be great, because, in my opinion, there are too many of them in MP.
The only way to disable MP-specific items in GZDoom right now is to start a game in singleplayer, create a save, and load that save in multiplayer.
