StructureSpawn

StructureSpawn is a lightweight yet powerful plugin that lets you create custom 2D or 3D structures which can trigger commands, effects, or mob spawns when built or activated by players.
Everything is configured in YAML — no coding, no commands, just creativity.

Perfect for RPG servers, adventure maps, or survival events, StructureSpawn brings your world to life with rituals, altars, monuments, or hidden triggers that players can discover and activate.
