Spartan AntiCheat & AntiExploit v4.0.8.8

Corrected several null-pointer console errors caused by the Location object not having loaded its Block object with information.

News:

• The Asynchronous Detections feature was recently brought back to life. Unfortunately, some of its users had abnormally high amounts of false positives, server lag, or both. This update targets these issues by improving the synchronisation of object information between different threads, but also collectively running processes every tick instead of assigning each process to a reusable thread or otherwise its queue. This feature still remains experimental.
• Spartan has been further optimised in this update, by having its Location object no longer call chunks to retrieve block information when not required. This change should improve many situations where the code of a check’s detection doesn’t logically progress to its full potential.

Logs:

1. Corrected a few remaining IrregularMovements step script-based feature false positives.
2. Slightly optimised the IrregularMovements step detection with less method calls.
3. Noticeably improved the Elytra handler by using ViaVersion to identify the player’s version.
4. Noticeably improved the Player, Block, Combat & Move utilities with significant reduction in location calls.
5. Noticeably improved almost all checks with significant reduction in location calls.
6. Noticeably optimised & improved the Asynchronous Detections feature with code rewrites.
7. Slightly improved the Spartan Player object with new advanced methods.
8. Noticeably improved the Spartan Location object with a significant reduction in chunk calls.
9. Corrected a Piracy system bug that caused Spartan to disable for [Censored] users.
10. Corrected a few IrregularMovements bouncing-blocks bed false positives.
11. Slightly improved the Spartan menu with more organised item descriptions.
12. Slightly optimised the Fly check with less method calls.
13. Slightly optimised the Player utilities with unnecessary method removals.
14. Corrected a few MorePackets limit related boat false positives.
15. Moved the MorePackets check to the main thread due to abnormal amounts of false positives.
16. Slightly improved the Fly check’s verbose information with more detailed descriptions.
17. Slightly improved the BoatMove check with faster detection codes.

Transferred some asynchronous processes related to block breaking, block placing & environment interacting to the main due to false positives.

News:

• Spartan was previously compatible with Bedrock players by identifying them using the Bukkit version of Floodgate/Geyser & exempting them from all detections. A new settings.yml option has been introduced to help identify Bedrock players that are allowed access via BungeeCord/Proxy plugins. In addition, most of Spartan’s detections will now support checking Bedrock players, so server staff can have less stuff to worry about.
• Spartan introduced Asynchronous Detections in the distant past. Due to some complications, a large part of this feature was forcefully disabled. This update resolves these problems and once again makes most of the plugin’s detections asynchronous.

Logs:

1. Reversed some very recent changes on the Fly check to prevent potential bypasses.

Settings.yml Changes:

Code:

Removed:
Punishments.broadcast_on_kick
Punishments.broadcast_on_ban
Teleportation.fall_damage_on_teleport
Teleportation.ground_teleport_on_detection

Added:
Punishments.broadcast_on_punishment
Detections.fall_damage_on_teleport
Detections.ground_teleport_on_detection
Detections.run_asynchronously
Important.bedrock_player_prefix

Corrected an Elytra handler no-such-method console error for server forks based on 1.8 Minecraft or earlier.

News:

• This update was released prior to its date to correct a lag issue several customers had to deal with. Build 374 introduced location caching, which also is included in Build 375, which unfortunately ended up causing lag instead of helping. I have reverted the changes and made additional improvements, so performance should be equal to Build 373 or even better.
• A server refreshes most of its data 20 times in a second. This resource follows this frequency and checks players via many of its detections 20 times in a second. Movement checks are the heaviest, and most of them will now skip checking a player a few times per second in specific situations to help save performance.
• Many of the plugin's schedulers that used to run on the main thread will now run asynchronously and take use of other cores/threads the CPU has to offer. Some of them are also hybrid, meaning they will run on the main thread only when required, and otherwise asynchronously.

Logs:

1. Corrected dozens of MorePackets boat liquid block false positives.
2. Slightly optimised the Liquid protection with faster methods.

8. Corrected a bug in the Spartan Player object where individual player weather wouldn’t be updated.
9. Implemented new events in the plugin’s listeners to allow proper weather change handling.
10. Password related content will no longer be normally shown in the Configurations inventory menus.
11. Corrected a few Fly calculated fast falling false positives.

25. Corrected a MineTinker compatibility console error by updating the dependency files.
    
26. Corrected dozens of elytra movement false positives caused by the NPC compatibility.

News:

• This update was released prior to help locally stabilise the MorePackets check instead of using the Cloud feature, and ultimately allow further potential corrections to take place.
• The plugin’s commands now come with the overly requested tab completion, but also descriptions briefly explaining their purpose. Some of them can also be clicked for their execution or a form of it to take place. This should help existing and especially new customers to better learn & use the plugin.
• The Hacker Finder inventory menu now also includes player punishments as part of its descriptions. This has been an often requested feature and should help Syn customers to better & faster identify hackers while further eliminating false punishments.

Logs:

1. Corrected a trivial issue where some of the default config.yml punishments would start from the 2nd command.
2. Corrected a few remaining KillAura area mob/animal farming & mcMMO false positives.

19. The plugin’s commands now come with descriptions briefly explaining their purpose.
20. The plugin’s command introduction now allows you to visit the plugin’s official website.
21. Slightly optimised the Command Execution handler with less method calls.
22. Potentially corrected several ImpossibleActions scaffold cached limit false positives.

News:

• The MorePackets check has been completely rewritten. It was previously a collection of 5 detections, one of them being fairly unstable, hence also disabled by default. Now, it is one only detection supporting omnidirectional movements, vehicles & lower amounts of timer.
• In the past, specifically in the release of Build 365, Spartan received a major optimisation which was the caching of directional locations. This ultimately reduced location calls by a lot and many users provided positive feedback. This update attempts to do the same with Spartan’s location object, which is responsible for over 90% of location calls.

Logs:

1. Completely rewritten the MorePackets check, ultimately reducing detections from 5 to just 1.
2. Corrected an Invisible Block bug handler problem with vehicle exiting.
3. Improved the Hacker Finder, Suspected Players, Legitimate Players, Wave & Reports inventory menus with in-order item adding.
