SpecLock

When a player is in Spectator Mode and belongs to a team, they can only spectate teammates, and they can only stay within a configurable block radius of them. Stray too far, try to fly off, or follow a teammate into another dimension, and you'll be snapped right back. Players with no team assigned are completely unrestricted.

Made to complement my Manhunt Plugin, or any scenario where you want spectators to still enjoy the spectating experience without being able to abuse it.

Features

Team-based spectator locking: spectators can only use the hotbar menu to teleport to players on their own team(mate)
Configurable radius: set the maximum distance a spectator can be from their teammates (default: 10 blocks)
Auto-teleport enforcement: checked every second; if a spectator wanders too far they are instantly snapped back to the nearest teammate
Cross-dimension follow: if a spectator's team(mate) moves to another dimension, the spectator is teleported with them
No restrictions for teamless players: players not assigned to any team are fully unrestricted in spectator mode
Persistent teams: teams and memberships survive server restarts

All commands require speclock.admin permission (usually just OP)

Technical Details
