Spartan AntiCheat & AntiExploit v4.0.8.8

The longest living Minecraft paid anti cheat! | 25+ Languages | Folia/Geyser/Cross-Version Support
Corrected a no-such-method error for old Minecraft server versions.
News:
  • The FastBreak check has been very reliable, but has often had issues with too much restriction or too much leniency. This is caused by the check’s code being hardcoded and not calculated, which prevents it from adapting and creates bugs as Minecraft releases new versions. This update completely rewrites a part of the check to be based on calculations, bringing ultimate precision with it.
  • Many checks and their detections date back to 2016, which is the year Spartan released. Over time, Spartan’s system changes, and many of its components change in ways that can malfunction if not properly maintained. In this update, I returned to checks that have been untouched for long and maintained their codes, throwing away unneeded methods, variables & optimizing necessary ones.
Logs:
  1. Corrected a bug that prevented the mcMMO & TreeFeller compatibilities from loading.
  2. Greatly improved the Block utilities to provide more universal methods.
  3. Corrected a bug in the Player Info inventory menu where some items would not work.
  4. Modernized the NoSwing check with a recent & rewritten code structure.
  5. Noticeably improved the mcMMO compatibility with more universal methods.
  6. Noticeably improved the FastBreak check with a rewritten delay detection and better verbose information.
  7. Noticeably improved many checks with better & rewritten verbose information.
  8. Removed the broken ImpossibleActions cactus detection and its checks.yml option. (ImpossibleActions.check_cactus)
  9. Removed the 2 checks.yml detection options of the FastHeal check and replaced them with a singular better detection. (check_unusual, check_illegal)
  10. Removed the 3 checks.yml detection options of the FastBreak check. (check_durability, check_moves_in_between, check_frequency)
  11. Greatly improved the Debug feature with more precise descriptions of a situation.
  12. Reverted some changes made to the Floodgate compatibility to improve the bedrock player identification.
  13. Corrected a bug in the Spectate feature where player flying would not enable if flight was allowed.
  14. Noticeably improved the Spartan Player object with more updates of its cache.
  15. Corrected a potential bug in the Player Swim handler that could have caused inconsistencies.
  16. Noticeably improved the Material utils with a method to judge the block breaking speed.
  17. Corrected dozens of elytra false positives caused by cache & Bukkit inconsistencies.
News:
  • The Spartan Player object is a replicate of the Player object Bukkit offers, but has increased variable speeds. In this update, the vast majority of remaining uses of the Player object were replaced to help unify many codes, and overall create a more organised environment for the future.
Logs:
  1. Corrected a small bug in the KillAura advantage detection.
  2. Rewrote most classes to contain only the Spartan Player object.
  3. Noticeably improved the Spartan Player object with new methods & removal of redundant uses.
  4. Removed unnecessary variables from the Ban feature.
  5. Greatly improved the Cloud feature with more consistent methods.
  6. Corrected a few verbose misinformation & bugs in the new Velocity check.
  7. Slightly improved the Cache system with more detailed key lists.
  8. Greatly optimized the Spartan Location object with numerical instead of text memory keys.
  9. Slightly improved the Register handler with better memory allocation.
  10. Slightly improved the Floodgate compatibility with version-based optimisations.
  11. Bedrock Players will no longer have their heads/skulls cached in inventory menus.
  12. Noticeably improved the tracking handlers with less & more compact classes and universal methods.
  13. Removed an unused system object named Position.
  14. Slightly improved the Decimals object with more useful methods.
  15. Updated the title of the Player Info inventory menu to be more unique.
  16. Noticeably improved the Spartan Open Inventory object with more accurate methods.
News:
  • With the recently introduced Velocity Analysis object, I was able to completely rewrite the Velocity check from scratch. The check is now 3x times smaller & significantly faster than its predecessor. It’s expected that it will catch a large variety of velocities, way more than its predecessor could even lightly detect, granted the anti-cheat is being used in a production environment where the Research Engine can collect information from players.
  • The Spartan inventory menu has been rewritten to have less items, less item boxes, smaller descriptions, and overall give attention to what matters instead of everything. In addition, a new item was added for Syn customers to allow them to view historical fights.
Logs:
  1. Corrected several HitReach bedrock player false positives.
  2. Completely rewritten the Velocity check with the help of the Research Engine & Player Profiling objects.
  3. Noticeably improved the Search Engine with additional caching resulting in faster methods.
  4. Completely revamped the Spartan inventory menu with less & better items.

  7. The Suspected Players inventory menu will now list online identified hacker players.
  8. Corrected a bug where the Hacker Finder inventory menu would not open if there were not enough logs.
  9. Created a new inventory menu for the Syn users named Player Fights.
  10. Corrected several TreeFeller incompatibility false positives caused by the mcMMO plugin’s abilities.
  11. Potentially corrected a MagicSpells plugin compatibility issue that would result in permanently canceled checks.
  12. Corrected a bug in the KillAura fight-analysis detection that caused certain data to be skipped.
  13. Noticeably improved the KillAura check with new ways of running some of its detections.
  14. Corrected several IrregularMovements fall & down slow-falling potion effect false positives.
  15. Slightly improved the Spartan Player object & Player Data utilities with better usage of potion effects.
  16. Slightly improved the Vehicle Access handler with more universal methods.
Provided the Research Engine with some necessary optimisations to return to the great performance of Build 448, or even better. Thanks for being patient and understanding.
News:
  • Implemented a Velocity Analysis System as part of the Fight Analysis System to further extend the capabilities of combat learning. This will allow me in the near future to design & program new checks/detections that will offer higher stability and better performance.
Logs:
  1. Updated the verbose information of the IrregularMovements check to better fit the system.
  2. Potentially corrected a lag issue in the Search Engine handler.
  3. Corrected a few Criticals damage entity height false positives.
  4. Noticeably improved the Search Engine with new methods & more reliable usage of its parts.
  5. Corrected a bug where inventory menu heads would not load for Syn Mini customers.

Corrected a lag issue caused by the Search Engine and experienced by many users.
News:
  • This update improves the code in detail to prepare the plugin for upcoming major detection changes and new rewritten checks in the near future. Such a process is necessary to maintain high stability and a low rate of bugs & other issues.
Logs:
  1. Corrected several MorePackets silent timer bypasses.
  2. Corrected a few IrregularMovements no-down glide bypasses.
  3. Re-enabled the caching of player heads for the inventory menus.
  4. Corrected an issue where the Syn verification would take place after the Search Engine cache.
  5. The Search Engine handler will now cache files based on last-modification date.
