ZoneLock

Zone Lock is a vanilla-friendly mod that makes generated structures more engaging by preventing players from placing or destroying blocks inside them until they’re completed.

It introduces a new block, the Zone Lock Core, which can lock an area around itself when activated with a metal block.

The stronger the metal, the larger the zone that can be protected. The core is crafted with an Amethyst Shard surrounded by Deepslate.

While holding an Amethyst Shard, players can see the boundaries of active locked zones.

The mod also adds a new structure, the Amethyst Tower, which showcases how the Zone Lock system can be used to create more engaging adventures within the world.
