AntiSignEdit

A simple Folia-compatible Minecraft 1.21.x plugin that locks signs after a player finishes writing on them, preventing any future edits.

Features

• Locks signs the moment the sign GUI closes after placement
• Automatically locks pre-existing signs (placed before the plugin was installed) on first interaction
• Works with all sign types: classic signs, wall signs, and all hanging sign variants
• Signs can still be broken normally
• Ops and players with antisignedit.bypass can still edit signs freely
• Configurable message shown when a player is blocked (or disable the message entirely)
• Folia compatible via RegionScheduler

Permissions

Configuration

Located at plugins/AntiSignEdit/config.yml after first run.

messages:
  # Set to false to silently block without sending any message
  send-on-block: true

  # Supports full MiniMessage formatting
  edit-blocked: "<red>This sign has been locked and cannot be edited."

How It Works

New signs: When a player closes the sign editing GUI, SignChangeEvent fires. A region-scheduled task (Folia-safe) immediately waxes the sign block after the event resolves. Waxed signs cannot be opened for editing in vanilla Minecraft.

Pre-existing signs: When a player right-clicks any unwaxed sign, the plugin waxes it on the spot before cancelling the interaction. This means old signs are retroactively locked on first touch.

Bypass: If the interacting player is an op (player.isOp()) or has the antisignedit.bypass permission, the interaction is not cancelled and they may edit freely.
