A 1.13 - 1.17 anticheat

  1. TheDoominator
    Native Minecraft Version:
    Tested Minecraft Versions:
    • 1.13
    • 1.14
    • 1.15
    • 1.16
    • 1.17
    Source Code:
    Working on a re-code, it will include 1.8 - 1.17 compatibility, more checks, better performance and more features so updates will slow down. I will try to add a few new checks while I'm working on that though. You can see progress here https://trello.com/b/R2LLkjzg/flappyac-rewrite

    Dev builds for full release are available here


    IP: test.flappyac.com
    MC Version: 1.17.1
    AC Version: Latest dev build

    This is currently mostly for testing the base I've made to make sure there are no bugs, once I've done that i will add more checks

    Flappy Anticheat is an anticheat I am making, it currently uses events but I'm going to use packets eventually. I will do my best to fix false positives and bypasses. I aim to make this anticheat highly customizable through the config so every message and check will be customizable.

    This should work 1.8 - 1.17 but its only tested on 1.13/1.17

    - Fly A

    - Speed A
    - Reach A
    - HighJump A
    - Timer A
    - Inventory A

    Known Falses
    - BadPackets B: Just can happen if the player has a bad internet connection (Cant be fixed)
    - Speed A: By slime launching
    - Speed A: By eating and jumping up blocks

    - Reset violations command
    - Violations reset every 5 minutes (Can change in the config)
    - Violation/Punishment Log
    - Reset Violations command
    - Customizable config

    Planned Features
    - More checks
    - Ban wave
    - ViaVersion compat
    - View player profile command (player client brand, violations etc)
    - GUI for enabling checks etc
    - Lag back feature/cancel??? Could be an extension
    - Proper 1.8 - 1.17 support possibly
    - Alert interval
    - Max ping (add with pingspoof check)
    - Possibly customizable buffer
    - Discord integration
    - Stop certain client brands joining
    - Include ban config for easy switch, could be on discord or with download
    - Maybe create a website that lets you edit the config easily (change from kick punishments to ban punishments quickly)
    - Better way to get values from config
    - 1.17 support

    How to use the API

    Hands down the best free anti-cheat I have ever tried with only a few slight issues. To begin with, there is a false positive where if you sprint and hold space you get kicked, although it can be easily fixed by disabling jump check in the config. I also noticed that it causes a considerable amount of lag on my small server which is the only reason I've been refraining from using it. therefore, a fix would be greatly appreciated.

    overall, as I said, this is an amazing anti-cheat. 10/10 would recommend.

      Thanks for the review!

      The jump check is a bit buggy at the moment. With the false when you sprint and hold down jump can you please join the discord so I can get this fixed? https://discord.gg/wVCSqV7ptB

      Also working on the full release which will have much better performance and much better and more checks

    Love this plugin. Best free anti-cheat I've ever used. I love it. My only issue with it, is that is has a false positive when I walk on campfires with no blocks under it. I hope it gets resolved. Will give 5 stars if it does. :D

    Amazing anticheat, fly checks are pog, speed checks are eh. Would say that the fly is the BEST check in this AC, my private anticheat has way more checks but it's still not as good at detecting fly, and didn't want to skid this fly (since it also has some falses)

    Honestly as an anticheat developer I know how it feels to get average ratings whilst being new. The developer is super duper nice and the plugin does what it says properly and is better than most spigot anticheats already lol.

    Anyone rating it for bypasses for checks that don't exist is just high. So the ac being decent + the dev being nice I'd say it deserves 5 stars.

    Oh and did I mention that it uses packets yes big chad.

    Pretty good anticheat, yet the speed check is a bit iffy since it's only air speed and a couple other are pretty easy to bypass!
    Anyways continue updating this anticheat!

      Thanks for the review! I will work on an onground speed check. Once I finish the recode it will work much better

    Hey TheDoominator, I see that you put a lot of time into an AntiCheat. Unfortunately, there are still an infinite number of bypasses, such as in the LiquidBounce client of NCP Fly. The bypass is due to the variable: boolean onGround = packet.getY() % 0.015625 < 0.0001, if you query the Y, it is yes also on the ground, if the player does not change his Y, better use a block check, besides, you should still block such things as Speed, because that is actually the most important things, LG ;)!

      I will do my best to fix these bypasses soon
      As for the speed check, I have been trying to get a working one but so far not successful as this is my first anticheat. I will keep trying though

    I downloaded this anticheat because i had problems with someone hacking my world and etc. it ended up kicking him. The only thing why im not giving this 5 stars but im giving 4 is because when i jump and build it kicks me for groundspoof A overall the rest is good it stopped the hacker this is the only issue i had
