Boar (an Geyser extension) is a proof of concept anticheat project that act simillar to server-auth-with-rewind on Bedrock for GeyserMC project with a few more checks and improvements compare to BDS.
⚠️ WARNING: THIS ONLY FOR BEDROCK PLAYER NOT JAVA PLAYER! YOU WILL NEED TO PAIR THIS WITH ANOTHER JAVA ANTICHEAT!
Also side note, there is ZERO guarantee about performance, update frequences, or if I will ever finish this.
I'm one again warning you I WONT'T GUARANTEE THAT THIS WON'T FALSE, THIS ANTICHEAT STILL IN VERY EARLY DEVELOPMENT.
Current detections list
Almost every single movement-related cheats (except vehicle), including - but not limited to
List of movement related dectections
Fly, Jesus, Step, Fast Climb, High Jump (Any type of fly cheats)
Speed (Any type of speed cheats)
No Fall (Detected using the fly check, impossible to bypass)
Velocity (99.99%/100.01% velocity - basically any kind of velocity cheat)
No Slow
And the list goes on....
Reach (> 3 blocks, depends on the config)
Hitbox (any kind of hitbox expansion, including touch player)
Timer (anything greater than 20 ticks)
What makes this anticheat "better" compare to other.
You can take a look at a list of "other anti-cheats" here
It's free..... and open-source, which is pretty dang good already.
Boar is extremly sensitive and can detect EXTREMLY small movement mismatch, designed based off the vanilla movement code making it mathematically impossible to bypass.
Boar can accurately detect and cancel any hit beyond 3.0 blocks reach with minimal falses while not affecting legit player but still accurately cancelling cheaters hit.
"Perfectly" account for client lag and latency lag without relying on tricks, making it harder to false lagging legits player while still effectively catching cheaters.
Accurately check for any timer-based check, even if the cheaters only move 1 ticks faster (1.001x - 1.05x game speed) boar can still catch and detect it, without affecting lagging players.
Note
It's not perfect, expect falses, and a lot difference that Bedrock have from Java is un-implementated, so if you do find a bug/false, do report it.
