Hey there!

This is super non-production ready! It contains [STDOUT]s in code that may eat your log. Just kidding, but really make sure you don't use it in production. False positives are still a thing, your players might get spammed / kicked. There are some reports of players seeing Herobrine-like creatures. This mod is haunted.

Please test before using!

GolfIV

A Fabric anticheat.

Current checks

For latest info see javadoc.

• Survival

  • yesFall - re-enables NoFall damage and checks for Jesus hack.
  • checkFlight - detects flying (flight). No boatfly detection yet
  • noSpeed - detects speed hacks. Needs to be redone.
  • antiTimer - checks whether client is using timer check to speed up the game. Still not usable with internet lag. Needs to be redone.
  • preventElytraHacks - prevents some elytra control hacks, still messy. Needs to be redone.
  • checkForStrangeItems - prevents players from getting strange NBT items (stacked totems, incompatible enchantments etc.)
  • checkIllegalActions - checks if player is moving / chatting / hitting while having the inventory open.
  • checkHitAngle - Checks the angle at which player is hitting the entity.
  • checkHitDistance - Checks if player is using reach hacks.
  • checkKillaura - Checks for killaura by summoning a fake player.
  • checkWallHit - Checks if player is hitting entity through wall.
  • removeHealthTags - removes health tags from entity packets.

• Creative

  • preventCreativeStrangeItems similar to checkForStrangeItems, but blocks all tags except for BlockEntityTag, used for block-picking. All tags are cleared when inventory is opened.

Currently players are kicked out if they are detected for hacking. This will probably change in the future. Wanna help design a punishment system? See #3
