Lightning Grim Anticheat

• Edited buildscript to force rebuild against my PE fork to fix blocks diappearing, issues with trial spawners and suspicious gravel, several other minor issues etc...

• Fix 1.21.4 teleport simulation errors
• Rebuild with new PE fixing grass blocks disappearing due to mapping bug

THIS REQUIRE A CUSTOM PE FORK TO FIX SOME BUGS. DO NOT CONTACT ME ABOUT BLOCKS DISAPPEARING UNLESS YOU ARE USING THE LITE VERSION AND THIS PE BUILD OR NEWER IN MY PACKETEVENTS FORK https://github.com/Axionize/packetevents/actions/runs/14158016425

Massive internal changes made, please report any issues!

• Memory usage hugely reduced
• Updated upstream to 32c75c78b0bb89ace6193dd981d402806e0b6457

• Fix firework hitbox modeling

Fix upstream sillyness

• Fix painting hitboxes and lite version adventure/packetevent errors:
  • Temporarily around errors with Painting Hitboxes on older (pre 1.19?) clients
  • Fix adventure shading errors with lite version by excluding it from being relocated in the lite version

• Fix HitboxEntity falses caused by wrong hitbox modeling for Falling Blocks and Paintings
• Fix upstream thread exception when accessing bukkit methods from netty threads
• Fix PacketEvents version check error message

Note: If you are using the lite version, fully fixing the falses with paintings requires merging in PRs from PacketEvents that are not in upstream yet. You can use this build of PE https://github.com/Axionize/packetevents/releases/download/temp/packetevents-spigot-2.7.1-SNAPSHOT.jar here built with this PR https://github.com/retrooper/packetevents/pull/1134.

HitboxBlock improvements, add build automation and more compile-time options

• Attempt to fix a rare HitboxBlocks false

• Fix a rare CME https://github.com/GrimAnticheat/Grim/pull/1984
• Improve modeling teleport packets for entities on clients < 1.16.2 (related to https://github.com/GrimAnticheat/Grim/pull/1985)
• Update upstream from f88a114e0ec5c07b9f568b5450d1ec29cd8b3cb8 to 439cbc6db3fe2119067398625490c41f601c88c5
• Fix HitboxEntity and HitboxBlock having issues with large attribute distances in ~1.21+
  • Optimize number of rays required to be traced in hitbox calculation

• Update upstream to f88a114e0ec5c07b9f568b5450d1ec29cd8b3cb8
• Fix https://github.com/GrimAnticheat/Grim/pull/1985
  • Note that hitbox offsets for passengers in vehicles are incorrect. Should not cause falses in most cases but this is theoretically possible and will be fixed soon.

• Update upstream from 896cf12b713f81314230ada6caa2fb3335947d0c to ff888f8c735a07023a4218b6a92016c983cc3946

• Mark LineOfSightPlace as experimental
• Make Inventory checks support/respect nosetback permissions
• Fix Entity tracker for <1.16.2
  • Note that Reach, HitboxMiss, and HitboxEntities may have a known false issue with changing an entity scales while they are being attacked for less than a tick.
  • Significantly improved false rate of HitboxEntities, lucky cheaters may escpae momentary detection but long-term will be found. Currently thought to be mathematically impossible to false.
• Added /grim hitboxdebug command that sends hitbox data to clients when attacking an entity, can and will be rendered by a client side mod like https://modrinth.com/mod/lightning-debug v1.1 and newer.
