Single Player SkyBlock for Low versions (with possibility to host LAN)

Good day.

I started a minecraft world with a clear idea to create a skyblock.

First, I needed a Skyblock Island generator. What it should make:

– Create an island.

– Create borders of the playable zone for each island

– Clone itself and destroy the previous model

Secondly, the island itself needed some features:

– Small login system (used mainly if uncontrolled hosting to prevent players, who change nicknames to grief)

– Spawnpoint linked to player

– Island itself (skyblock)

When the island creation is completed, we need a “spawn”.

Spawn is accessible through the command block on island;

Spawn has:

– Shop

– Credit room

That’s the minimum it does. Can be upgraded as one like and hosted, for example with Zerotier
