HyAntiCheat

HyAntiCheat (HyAC)

This is one of the first public AntiCheats for Hytale. Currently, this is in very early stages, but i plan to continue updating this very frequently over the next couple of weeks.

Current Features:

This is mostly an AntiCheat Base, not a lot of checks:

1 Timer Check

2 Simple Fly Checks

1 Speed Check

Prevents Teleport cheats by limiting max. distance per tick

Chat Notifications

Setbacks

Ability to cancel packets when cheats are detected

There is no auto-ban or auto-kick implemented yet. Only Setbacks for now.

As i have experience with Minecraft AntiCheats, i set this one up very similar to how mc anticheats are done. That means its fully packet based and uses similar internal systems. I believe this approach will work for hytale as well.

But, this is new for all of us. So, please dont expect an anticheat miracle just yet ;)

Can i already use this?

Yes, but please check for false flags or performance issues on your specific server and gamemodes first. If it doesnt work, let me know and i will try to fix it (If its reproducible). Please dont report bypasses yet, only falses. It should be able to detect the basic flight cheats that are currently available.

The current version was only tested on a local test server. Any feedback of running this on actual servers is valuable for me.

Permissions & Commands: See notifications: hyac.notify /hyac: hyac.command.hyac /hyac help: hyac.command.hyac /hyac silent: hyac.command.hyac.silent /hyac verbose: hyac.command.hyac.verbose /hyac reload: hyac.command.hyac.reload /hyac info <player>: hyac.command.hyac.info

In the config file you can set defaults for silent & verbose and disable checks by setting them to false. Note: Disabling "Fly" (for example) disables all sub-checks "Fly(A), Fly(B), etc". Will probably change this in the future.

Current Config:

{ "DefaultVerbose": false, "DefaultSilent": false, "AllowSetback": true, "EnableExperimentalChecks": false, "Checks": { "Fly": true, "MoveLimit": true, "Timer": true, "SpeedA": true, "HighJump": true } }

Will it be Open Source?

I'm not 100% sure yet but likely it will be in the future.
