Lightning Grim Anticheat

• BadPacketsX, PacketOrder, and LineOfSightPlace improvements
  • Refactor and improve numerous PacketOrder checks
  • Fix some BadPacketsX falses
  • Fix some LineOfSightPlace falses

Note that these changes require manually updating or deleting your config to be fully utilized

• Added a /grim history command that shows you historical flags players have triggered
• Split Reach into 4 seperate checks
  • Reach - checks if they hit from too far (known to be unfalsable)
  • HitboxMiss - checks if player missed the target entity hitbox (very rarely falses)
  • HitboxBlock - checks if a player hit an entity through blocks (no known falses)
  • HitboxEntities - checks if a player hit an entity through another entity - (falses uncommonly)
• Improved HitboxEntities to check through entities in Vanilla's iteration order, reducing false rate significantly especially in swarms of mobs or team fights. Note that this check is disabled by default.

• Fixed InventoryD not working due to upstream changes to simulation engine movement data.

• Hotfix loading Post check twice causing error

Update upstream

• Update upstream
  • fixed minor bugs
• Update PE to latest - includes shadow color text support
• Inital work for 1.21.4 support

• Experimental 1.21.3 support

• Fix Java 8 compatability

• Update upstream to 130f9e1023e6d203db710e74a0642cd3b3cda855
  • Should fix https://github.com/Axionize/LightningGrim/issues/14

• MultiActions checks
• Update upstream
• Revert Exempting 1.14.2+ no NoSlowC and NoSlowD. NoSlowC may false and NoSlowD will false but this will be fixed soon https://discord.com/channels/811396969670901800/1312295466091675742.

• Fix config issue where skip-block-check: true and skip-entity-check: false would cause numerous block falses
• Make LOSP use same direction calculations as Reach check; could fix some falses

• Add a warning to add -Dpaper.explicit-flush=true for extra reach accuracy if you have already enabled enable-post-packet under Reach for extra reach accuracy. You need both for maximum accuracy.
• Update config. Make checking for blocks blocking a hit on by default and checking for entities blocking a hit off by default (less tested). Both are configurable in new config as skip-block-check and skip-entity-check under Reach

• NoSlow fix for old and new clients on legacy servers and old clients on modern servers

• Quick patch for issue with riptide evicting queue being empty. Causes console spam and kicks on older versions.

• Fix library issues such as with fastutils being caused because previous jar wasn't relocated
• Fix riptide trident teams/non-pushable target falses. This also fixes players to go through other players on the same team with riptide.
