How It Works

1. Editing: Players with the permission structures.admin can edit structures using /structure edit <id>.
2. Client-Side Updates: Structures use PacketBlocks to ensure updates are only visible to specific players.
3. Saving/Loading: Structures persist in the configuration file and can be reloaded across server restarts.
4. Copying: Duplicate existing structures using the /structure copy <id> <new id> command.
5. Displaying Structures: Structures are visible by default, but can be hidden using the /structure view <id> <player> command.

PlaceholderAPI Support

If installed, the following PlaceholderAPI placeholders will be available:

• %structures_viewing_<id>% - Returns true/false depending on if the player is viewing the structure.
