Requirements

  • Paper 26.x (tested on 26.2-26.3)
  • Java 25

Features

Two independent detection systems. Each can be enabled, disabled, and configured separately.

Protected-block glitch prevention

When a protection plugin such as WorldGuard or GriefPrevention denies a block placement, JBlockGlitch resends the real block state and stops the player from moving through the client-side ghost block. It covers normal and bucket placements (water, lava, powder snow) and uses multiple event paths to stay compatible with protection plugins that handle buckets differently.

  • medium: rubberbands the player to their previous position on a denied placement.
  • strict: adds movement and position checks so players cannot stand inside or move through a denied block.

Vanilla ghost item and ghost block prevention

Detects common ghost item techniques such as F+Q, hotbar switching, dropping items, and block placement.

  • medium: detects common ghost item patterns.
  • hard: also monitors inventory manipulation events, including creative-mode inventory interactions.
  • brute-force: continuously resynchronizes player inventories.

The plugin can also periodically resync the blocks around each player (a 2x2x4 region) to fix client-side ghost blocks from client mods that never trigger a server-side placement event. The interval is configurable and this can be disabled independently.

Commands

Command Permission Notes
/jblockglitch help jblockglitch.help Shows basic plugin documentation.
/jblockglitch reload jblockglitch.reload Reloads config.yml and messages.yml.
/jblockglitch config <key> <value> jblockglitch.config Changes a config option in-game and applies it immediately, no reload needed.
/jbg jblockglitch.help Short alias for /jblockglitch.

Configuration

config.yml has independent options for protected-block detection, ghost-item detection, nearby block resync, and an update checker. Options can also be changed live in-game with /jblockglitch config <key> <value>. The help message lives in messages.yml as a multiline list. Messages use MiniMessage by default; set text-format: legacy in config.yml to use legacy & color codes.

Support

If you run into issues, regenerate all configuration files and download the latest version. If the problem persists, report it on the issue tracker.
