SpawnPointRestrictor

A server-side NeoForge 1.21.1 mod that restricts players from setting spawn points outside a configurable geographic boundary.

Features

Geo-fenced spawns — Prevent players from setting their spawn point (beds, respawn anchors) outside a defined area
Flexible boundaries — Configure circular or rectangular geo-fence shapes
Nether support — Respawn anchors checked with proper 8:1 coordinate scaling to match Overworld boundaries
Login validation — Automatically clears invalid spawn points when players join if boundaries have changed
Command bypass — Optionally allow /spawnpoint command to bypass restrictions

The mod uses server-side configuration (spawnpointrestrictor-server.toml).
