No More Portals
A simple mod to prevent players from going through nether portals
About this Mod
No More Portals
This mod prevents players from going through nether portals. That's it. I shouldn't affect any other entities, and it shouldn't affect any other ways of getting to the nether, such as commands or methods added by other mods; only portals should be affected.
Players in creative mode and entity types added to the nomoreportals:portal_allowed tag will still be allowed through portals.
