? ZBedRockBlock

Blocks Bedrock players (identified by a name prefix) from joining a backend Paper server behind Velocity.
No Floodgate hooks; purely name-prefix based. Built for Paper 1.21.x on Java 21.

What it does (and doesn’t) do

• ✅ Blocks players whose Java username starts with the configured prefix (case-insensitive).
• ✅ Kick reason supports MiniMessage (e.g., <red>…</red>) and legacy & color codes.
• ✅ Bypass permission for exceptions (trusted players, staff alts, etc).
• ✅ Admin commands for reload and test.
• ❌ Doesn’t talk to Floodgate/Geyser APIs or Mojang auth; it’s lightweight and proxy-agnostic.
• ❌ Doesn’t manage your queue; if you use a queue plugin (e.g., ajQueue), configure it to remove players on this kick reason.

Requirements

• Paper (1.21+)
• Java 21+

Optional dependencies

• LuckPerms (or any permissions plugin)

Installation

1. Place the JAR into the backend server’s plugins/ folder.
2. Start the server once to generate plugins/ZBedRockBlock/config.yml.
3. Edit config.yml (see below), then /zbedrockblock reload.

Backend requirements:

• Server is behind Velocity and typically offline mode.
• Make sure Paper is proxy-aware (standard Velocity modern forwarding setup).

Configuration (config.yml)

enabled: true

# Ops are *not* automatically exempt; they must have the bypass permission.
ignore-ops: true

# Single, exact prefix (case-insensitive). Example: "." or "bedrock_"
bedrock-prefix: "."

# Kick message supports MiniMessage and legacy & codes.
kick-message: "<red>Bedrock accounts aren’t allowed on this server.</red>"

# Logs match decisions to console if true.
debug: false

messages:
  reload-success: "&aZBedRockBlock config reloaded."
  no-permission: "&cYou don't have permission."
  usage-test: "&cUsage: /zbedrockblock test <name>"
  test-header: "&7Kick preview (as seen by player/proxy):"
  test-allowed: "&eTest for &f%name%&e: &aALLOWED"
  test-blocked: "&eTest for &f%name%&e: &cBLOCKED (would be kicked)"

Tips

• Choosing the prefix:
  Use the same prefix your Bedrock players receive on Java (e.g., ".", "BD_", or "bedrock_").
• MiniMessage example:
  kick-message: "<red><bold>No Bedrock accounts on this server.</bold></red>"
• Legacy example:
  kick-message: "&c&lNo Bedrock accounts on this server."

YAML gotcha: Keep MiniMessage tags inside the quotes.
✅ "<red>text</red>"
❌ "<red>text"</red>

Commands

Tab-completion is included.

Permissions

To whitelist a specific Bedrock player, grant them zbedrockblock.bypass.

ajQueue / Queue plugin note (important)

If you use ajQueue (or similar), make sure it removes players from the queue when they’re kicked by this backend.
A simple way is to include a keyword in your kick message (e.g., “Bedrock”) and configure ajQueue’s “kick reasons” list to match that word. ajQueue will then pop them out of the queue instead of looping them.

Example approach:

• Keep the default kick message ("Bedrock …") or any message containing a consistent keyword.
• Add that keyword to your queue plugin’s configuration where it looks for contains matches in backend kick messages.

Compatibility

• Server: Paper 1.21.x (including 1.21.10)
• Java: 21
• Proxy: Works fine behind Velocity. No Velocity/Waterfall helper plugin required.
• Other plugins: Plays nicely with virtually everything; it only reads config and listens for PlayerLoginEvent.

Common scenarios

Block all Bedrock users across one backend:

bedrock-prefix: "."
kick-message: "<red>No Bedrock accounts on this server.</red>"

Allow a specific Bedrock user (staff alt):

• Grant them zbedrockblock.bypass via your permissions plugin.

Temporarily disable the plugin without removing it:

enabled: false

Then /zbedrockblock reload.

Troubleshooting

• YAML error on reload:
  Most often a quoting issue in kick-message. Keep the entire message in quotes if you use <tags> or & codes.

• Players looping in queue:
  The queue plugin isn’t configured to drop them on this kick reason. Add a keyword from your kick message to the queue plugin’s “kick reasons” list (or equivalent).

• “429” Mojang warnings on startup:
  That’s Mojang rate-limiting for profile lookups (skins), usually triggered by skins/heads/cosmetics/tablist plugins—not this plugin. Consider enabling caches or disabling startup fetches in those plugins.

• Ops getting blocked:
  This is by design. If you want ops exempt, either set ignore-ops: false (lets ops in even if they match) or grant ops zbedrockblock.bypass.

Uninstall

1. Remove the JAR from plugins/.
2. (Optional) Delete plugins/ZBedRockBlock/ if you don’t need the config anymore.
3. Restart the server.
