Nether Portal. A nether portal is an obsidian structure enabling players to pass between the nether and the overworld. Players around the portal will receive a message when the spread effect begins and when it is prevented.
You can then use this nether portal to easily move between the overworld and the nether, whenever you like. A nether portal cannot be built horizontally like an end portal. Likewise, minecraft nether portal calculator is used to compute the relative coordinates between the overworld and the nether.
