Plugin Description §


Mockingbird is an anti-cheat in development made for fun by an ethic idot - version v2 has many changes compared to the v1 variants of Mockingbird.

If you are upgrading from v2.1, please reset your config. I will try to work on an auto-updater for the config in v2.3

Here's something I want to relay before moving forward:

  1. If you have an issue with Mockingbird (constant falsing, too much cpu usage, etc.) please make an issue on the GitHub repository with details, so I can fix it. You can leave a bad review but please make an issue :)
  2. Find a bypass (for movement detections only)? Make an issue on the GitHub repository with a video.
  3. Got a feature suggestion? Don't put it in reviews - make an issue on the GitHub repository.

Mockingbird no longer has a test server to test because I am poor.

V2 Changes

Mockingbird's base inspiration comes from Neptune made by shura62

TLDR (if you don't care about all the dev stuff): Same checks, and new base. TLDR List:

  • New Base
  • Same and new checks
  • More accurate
  • Cheat probability
  • Reward system (for when players pass checks to prevent falses)
  • Less CPU Usage

Well, first things first - detection modules are no longer event listeners, instead, Detections extend a Detection class which has a function called "process" which runs every time a packet gets received from the player.

Before Detections process data though, "processors" process data before the check. These processors handle data and save them into the player's "User" class so all checks can use them. For instance, the FlyA check gets the User's move delta (vector3) and does math from there.

Every time a player joins, it will register a "User" class for them. All available checks will have a new instance made from a reflection from Mockingbird's main class made when the plugin enables and put in a "checks" property in the User. Processors have the same process done.

Why? So I don't have to hardcode checks into a property in the User class.

Mockingbird no longer calls custom events.

There will not be a resetting violation feature unless Mockingbird is still false-punishing users. Instead, every time a user passes a check, they will be "rewarded". In rewarding, the player's violations for the check gets multiplied by a very small amount (multiplier varies based off the check). This will help with players which might false positive some checks at certain points, and is more effective than resetting all the player's violations.

Detections now have "cheat probability". What this will do is estimate the chance of cheating. This is determined by how many times a player flags a certain check a certain amount of times within a period.

Custom modules are still here, and now you can also add custom processors. Since I'm too lazy to make an example, uh, idk just figure it out or wait I guess.


This is a list of all the detections Mockingbird has, these detections may not be 100% accurate and false at sometimes, but the new reward system should compensate.

Combat Detections

  • Aim
    • (A) -> Yaw delta to pitch delta check
  • AutoClicker
    • (A) -> Consistency
    • (B) -> Speed
    • (C) -> Statistics
    • (D) -> Duplicated Statistics
  • KillAura
    • (A) -> MultiAura
    • (B) -> NoSwing
  • Reach
    • (A) -> Check w/ Location History
  • Hitbox
    • (A) -> Colliding Ray Check

Movement Checks

  • Fly
    • (A) -> Prediction Check
    • (B) -> AirJump Check
    • (C) -> Acceleration Check
  • Speed
    • (A) -> Friction Check (flags while using bhop and some other hacks)
    • (B) -> Speed Limit Check
  • Velocity
    • (A) -> Vertical Check (99% by default)
    • (B) -> Horizontal Check (95% by default)

Mockingbird also has packet checks.

  • BadPackets (checks for validity of packets sent)
    • (A) -> Pitch validity check
    • (B) -> MovePlayerPacket consistency check
    • (C) -> Checks if player hits themselves (can be used to bypass some checks?)
  • Timer (checks if player is sending too many packets in an instance)
    • (A) -> Balance Check (bad with server lag)

What's new §
  • New Checks
    • AutoClickerD
    • HitboxA
    • ChestStealerA

  • Internal Updates
  • No more lag from MoveProcessor
  • Logo
  • New Base and same (and improved) checks
  • PlAyErAuThInpUtpAcKEt!!!1
  • Reward system in detections (will lover VL if player passes a detection).
  • New checks: AutoClickerC, VelocityB (detects 97% horizontal velocity by default), Nuker (improved and much better), BadPacketsB and BadPacketsC.
  • Internal Stuff
  • Config: please reset k thx


  • Removed a bunch of checks (please reset your config for this update)
  • Improved AutoClickerB
  • Made AutoClickerA more strict.
  • Added 98% (sometimes can detect 99%) linear velocity check (VelocityA)
  • Fixed the screenshare feature not showing chunks (now uses teleport)
  • A bunch more, I made a lot of commits since 1.2-beta xd


  • Added debug log
  • Added option to make violations reset after a period of time. This will prevent legit players who may sometimes falsing Mockingbird from getting punished. By default, this option is enabled and will reset violations every 300 seconds (5 minutes).

There is more, please reset your plugin data to prevent any issues ;)

  • Add experimental Scaffold detection
  • Update AutoClickerA
  • Improve and update ReachA
  • Add option to disable or enable alerts in-game
  • Update logs command, the command has changed to /mblogs
  • Add debug messages and allow staff to enable or disable debug messages in-game (by deault debug messages are disabled)

thanks for the review! :D

Basic anticheat with weak checks. My friends made bypasses for this ac in a few hours lol
17 Aug 20
If you have found a bypass, please show a video of the bypass and make an issue at the Github repo so I can work on a patch ;)
using v1.0-beta
11 Aug 20
Very good anti cheat but you should make an option how sensitive it will be beacuse it gets triggered very easily and most of that is false
12 Aug 20
Currently with the way Mockingbird is designed, there isn't really a way to change the sensitivity of the checks. If you're having any issues with a certain check, you can report it here: :p Thanks for the review!
