Null Portals

Datapack:

A vanilla Minecraft datapack inspired by the Null army from Unstable SMP.
It recreates their signature way of moving: you choose coordinates, teleport there, and a Nether Portal appears around you as if you just stepped out of it.

Features

• Teleport to any coordinates in the Overworld
• Instantly spawns a Nether Portal at the destination
• You appear inside the portal
• Portal orientation automatically matches the direction you were facing

Main command

/function null_portal:strike {x:<X>,y:<Y>,z:<Z>}

Mod:

Server-side Fabric mod (Minecraft 1.21.11) that lets operators open linked, vanilla-looking Nether portals by command, inspired by NULL from Unstable SMP.

• /portal open <player> builds a portal in front of you and another in front of the target; the two are linked.
• /portal open <x y z> [dimension] does the same, with the second portal at the given coordinates in the Overworld, Nether, or End.
• /portal link <x y z> [dimension] links the nearest portal to an existing portal at those coordinates, including regular vanilla ones.
• /portal unlink removes the link of the nearest portal.

Portals use a full 4×5 obsidian frame, never replace existing blocks, and can spawn in mid-air. Links are two-way and permanent until either portal is destroyed. Then the link is removed and the surviving portal behaves like a normal vanilla one. Links are saved with the world.
