Is it possible to configure it to work only with weapon pick ups?

[sanscriptum]

For use with DoomRPG for example. Or does it need an .ini file?

Honestly, it's been so long since I've touched this project, I don't remember! 😅

My educated guess is you'd need an INI file, perhaps along these lines:

[Actor+]
AlwaysTouchPickup=yes

[Weapon+]
AlwaysTouchPickup=no

Note that some other mods, like DoomRL Arsenal, use separate non-Weapon actors that give you the actual Weapon when you touch them. In DoomRL Arsenal, these all derive from the RLBaseWeaponPickup class. You will need to list these as well, like so:

[Actor+]
AlwaysTouchPickup=yes

[Weapon+|RLBaseWeaponPickup+]
AlwaysTouchPickup=no
