AnarchyExploitFixes

Read the last release notes if you haven't already updated.

• Prevent supposed nocom bypass, check Use item packet as well.

Development is probably going to slow down because I have school, there will probably only be a release at most each month, or when a new exploit is discovered.

• Add minimum distance to vanish player when teleporting - Useful so player's don't teleport a ton of times to make tablist go crazy.

MinDistanceToVanishPlayer: 100 # Minimum distance to vanish player when teleporting, useful to prevent players from teleporting very fast in the same spot and making the tablist go crazy.

• Add first join message (#38) - Disabled by default.

EnableFirstJoinMessage: false
FirstJoinMessage: "&7%player% joined the game for the first time. They are %players_num% to join." # %players_num% is how many players have joined the server + the current one (ex. 351th)

• Add antispam for commands as well - Enabled by default:

AntiSpamCommands: true # Use the same antispam options for commands aswell.

• Add anti nether roof meant for public servers and not just mine.

# This will automatically teleport players below nether roof if they are too high. Use permission node anarchyexploitfixes.netherroofbypass to bypass
PreventNetherRoof: false

• Remove config boolean check for old/never used config option. (PreventGoingBelowBedrockFloorOnElytra). Proper config option is PreventGoingBelowBedrockFloor.
• Attempted work on kickphrase command - still seems to be broken. Not that big of a feature to waste time fixing.

• Add option to remove wither heads after x ticks or after chunk unloads, whichever comes first.

RemoveWitherHeadsAutomatically: true # Experimental: Will remove wither heads on chunk unload or if its been longer than x ticks
RemoveWitherHeadsAutomaticallyTicks: 200 # 10 seconds

• Add option to prevent too many (non living) entities in chunks, useful if players place a ton of crystals etc in one chunk to crash the server.

PreventTooManyEntitiesInChunk: false # Check all chunks every 30 seconds for too many entities, removes any entities left after reaching limit
MaxEntitiesInChunk: 100 # Does not include living entities. (animals/monsters) useful if players are placing a shit ton of crystals etc in one chunk and crashing the server.
LogEntityRemovals: false
EntityCheckTimeTicks: 20 # 1 second

• Slight performance improvements

• Add back end portal frames to the antiilegals, this was removed because the server thought players were placing end portal frames when activating portals, now it will only prevent placing end portal frames, placing eyes of ender is fine now.
• Antiillegals will now look inside ender chests.
• Add another argument to /aef lag. You can now customize the time it freezes for. /aef lag 10000 will freeze the server for 10 seconds.
• Code cleanup, small fixes, and make sure that everything can be disabled in config. (#37)
• Fixed issue where the tps counter used for disabling redstone at certain tps was broken.
• Removed the old code that prevents players from flying in new chunks on the nether roof, this was meant for my server. (#36)

• Allow customizing the maximum projectiles that can be fired in X time.

ProjectilesMaxPerTime: 3
ProjectileTimeTicks: 10 # 3 projectiles can be sent every 10 ticks (0.5 seconds)

• Added back the code for checking illegals in shulkers, however added a warning that this may cause a dupe. Server owners have noticed this hasn't happened on their 1.12.2 servers. Try at your own risk.

LookForIllegalsInShulkers: false # WARNING: DO NOT ENABLE IF YOU DON'T WANT A DUPE. Atleast in 1.17 shulkers can easily be duplicated with this enabled. https://cdn.discordapp.com/attachments/810446565822038016/858851144750989312/jbIAkzJ9CU.mp4

• Add option to prevent burrow if there's a block above.

PreventBurrowIfBlockAbove: false # Prevent burrow even if there is a block above the block they are burrowing in, please note this may allow creating an "elevator", players will keep teleporting up until they hit air

• Very small code enhancement in illegals
• Very small grammar fix (#34)
• Fix potential memory leak

• Freeze pistons if tps is below the redstone tps specified in config.yml.
• Prevent beacons from being used to burrow.
• Prevent breaking end portals with a piston.
• Remove unused code
• Clean up code

• Patch the recent "NoCom" coordinate exploit. Update ASAP
• Patch bedrock burrow

• Check if player is temporary in the protocollib events.
• Add max banners per chunk.
• Less false positives for burrow patch.
• Temporarily disable shulker checking from #30 pull request. Seems to cause a duplication exploit (atleast in 1.17)

• Add AntiBedTrap (#30)
• Add option to revert items in shulkers (#30)
• Improve the checking for books, this should fix any error messages you got from last version. (#30)

• AEF now has one of the best book ban patches available for 1.12. The page is automatically removed if the bytes are over 255 (Limit for normal characters). This may be a problem if your main playerbase language heavily uses unicode, such as Russian or Chinese, however. (#29)
• New version scheme. AEF now uses semver, which is why the version changed to 1.18.12.

Last 3 updates have been removed so they don't fill up the releases page.

18.0.11.3:

• Patch illegal heads, will not remove normal skulls/heads. Only removes player/steve heads.
• Tried multithreading RemoveIllegalBlocksOnCHUNKLOAD, doesn't improve performance much in my testing, might improve for you.
• Increase default autocrafting recipe cooldown to 5 ticks. (Autocrafting, not manual, this has a lag exploit)

• Disable ExperimentalDupePatch2 by default due to a load of bugs.
• Add another check to the falling blocks prevention to hopefully prevent some lag.
• Clean up event registering (#16)

• Limit falling blocks in a chunk, prevents any falling blocks from falling if there is more than 50 falling blocks in a chunk.
• Limit experience bottles, prevent having a shit ton of exp bottles in one chunk then loading it to kill the server
• Prevent projectiles such as xp bottles and snowballs from going through portals, this can cause a shit ton of lag especially if there is new chunks on the other end, this wont prevent mobs or items

• Added an option to disable 1.16 fish because they can spawn a ton at once and cause a shit ton of lag.
• Disable ExperimentalDupePatch2 in 1.16 because it causes a SHIT ton of mobs to spawn, and not despawn. https://i.imgur.com/f691cep.png
• Disable any chunk checking in 1.16 because it causes a shit ton of errors

• Fix the config options on 1.16

• Add a new experimental godmode/dupe patch, disabled by default, you can enable by setting ExperimentalDupePatch2 to true, this will prevent any entities from despawning within 500 blocks from a player.
• Set RemoveALLIllegalBlocksOnCHUNKLOAD, FillInBedrockFloor, FillInBedrockRoof to false if the server is not on 1.12.x, this is because these cause a shit ton of errors on newer versions. You can bypass this by setting OverideConfigChanges to true
• Disable PreventPortalTraps by default because this is part of the anarchy experience.
• Added AntiSpam messages per x time, default is 10 messages every 30 seconds or about 1 message every 3 seconds if spamming.
• Fix colors in reload command
