    Reporting Errors the follow things have to be mentioned:
    • CB Version and AXR version
    • Whether you started the AXR version with a fresh ore file or not (doing /axr off before upgrade)
    • If not, since what version you've been using the same ore file.
    • If you get any errors in console, check the debug.log for "Error"s and "Warning"s. and post those.

    Upcoming features for 0.7:
    - AXR Chest chest hiding feature developed by MrSelfDestrukt
    - New advanced visibility test (almost done, only need to test it now and decide whether its going to replace or be an alternative to the original light based test) Details here and here


    AntiXRay hides ores from players by turning them into stone until they have been exposed, thus making it impossible for any client side hacks to detect them, as their location is not sent to the client.

    Backup your world(s) I cannot guarantee that ore doesn't disappear from them due to this plugin. Even if you did not backup, there is a foolproof solution here. If you decide to uninstall, type /axr off, and not delete the ore data file before your ore is restored unless your intention is to strip your worlds from ore.

    If you upgrade from 0.5.21 it is recommended that you do /axr off first flush out errors from the ore file. If you do not have enough RAM, you can do this in steps using 0.6.9 but you need to set lenient=true in the config file to allow the file to be loaded
    NSCommand <-- Required
    Source and old versions

    - Specify what ores to hide(works with non ore blocks too as long as they don't use data values or extra data such as chests and signs (use some chest locking plugin for keeping your chests from xrayers)
    - Multi world support
    - Permissions support
    - Stores ore data in binary files (one per world) and only keeps data about loaded chunks in physical memory. It is on average 400 bytes per chunk in and guesstimatedly around 450 in physical memory, so it is reasonably small, but some people might play on huge worlds and want to conserve memory.
    - Saves data about chunks immediately on any changes (they are assumed to be by far sufficciently rare that any performance is won by buffering is neglible. As such it also prevents potential ore duplication on server crashes)
    - chunk and world statistics
    - ingame map of loaded chunks
    - background processes that does not freeze the server
    - dump ore statistics into file and compare them to see the changes in ore content.
    - lots of configuration options

    Ores will become visible under any of these circumstances:
    - A surrounding block is lit by torch and player is within the chunk or adjacent chunk and within 16 blocks to player on Y axis.
    - A surrounding block is lit by a third block broken falling or removed by explosion and player is within the chunk or adjacent chunk and within 16 blocks to player on Y axis (occurs once every 2 seconds, but configurable).
    - A surrounding block is broken or falls or removed by explosion
    - A surrounding block is changed by another plugin (can be cpu intensive if you worldedit a big area for instance - might do a workaround for this)

    Current Limitations:
    - Ores at light level above pitch black on chunk generation will not be hidden e.g. near lava or surface cave entrances.
    - Ores will not be found exploring caves in pitch black (who does that anyway?) These two limitations was to allow a light based visibility test that relies on a test already built into the server, thus avoiding extra performance overhead as well as headache of coding it myself. Despite these limitations, AntiXRay should make it far beyond pointless to search for ores using XRay or transparent textures.
    - Gravel and sand dropping on chunk generation may expose ore. This is assumed to be rare enough to have neglible effect.
    - The data file will not repack itself. The ratio between generated ore and mined ore is assumed to be very high, and the file size is considerably small but nonetheless, should you want to "repack" it, just turn axr off and on and the new file will be smaller excluding the gaps between chunk entries. But again, do some basic math and count the amount of ore blocks mined in total, multiply that by 2 bytes. After a month of mining 10000 ore blocks, you shaved 20k off that 3M file.
    - If you place a torch there is a tiny delay as seen in the video due to client side prediction and lag between the time the info of the ore to get back to the client from the server. This can seem unnatural so I might make a better vision test later that doesn't rely on light. However it would be more expensive in terms of cpu cycles.
    - If you have a slow server or a lot of players, you might want to remove coal from the config list. It speeds it up at least 200%. There are some optimizations I can do that I might add later that will speed up things further.


    /axr on - hides all unlit ore

    /axr map -shows map of loaded chunks in current world
    /axr map <world> -shows map of loaded chunks in specific world
    /axr map <zoom>
    /axr map <world> <zoom>
    /axr map <x> <z>

    /axr dump <world> <file>
    /axr diff <filein1> <filein2> <fileout>
    /axr gen <world> <x1> <z1> <x2> <z2> command for generating a rectangular area of chunks
    /axr gen copy <world1> <world2> command for generating all the chunks in world2 that are registered in world1
    /axr pack <world> - removes dead space in ore file (not that there is much from just mining but the axr chest will create significant amount of dead space.

    schedulerload - 0-100 percentage of time going to execute any background process.
    schedulerstatustimer - time in millisecs between each status report of a background process
    filterorenotinstone - filters ore upon exposition that is not in stone (can be used to restore ore from a backupped ore file or ore file generated from a fresh world with same seed)

    autobackup - backup ore files automatically at startup(requires autorepack) - on by default
    maxfaces - specify max amount of exposed faces per chunk before error occurs
    lenient - ignore lindex errors when loading file (useful if you have them from before and want to filter them out)
    All CMD_... options are for redefining the commands so you can type something else.

    • Fixed Array index out of bounds in listindex accessing materials that has not been loaded yet.
    • Added /axr mirrorworld <world> <mirrorworld> command
    • Fixed NPE when trying to expose ores in world hole.
    • checking whether wrong file exist during repack.
    • fixed NPEs in some commands that can occur if you use it and the world is off.
    • fixed open file pointers during repack.
    • fixed NPE during repack when load fails.
    • fixed NPE when running test on all worlds and not all worlds are on
    • added various memory checks and chunk data entry overwrite checks
    • fixed NPE when trying to flush the debug file when debug file is turned off.
    • added lenient config option to ignore lindex errors when loading file (useful if you have them from before and want to filter them out)
    • added more information on error when loading from file
    • added config option maxfaces to specify max amount of exposed faces per chunk before error occurs
    • /axr off now gradually unregisters chunks - as a workaround to what appears to be a problem with chunks not getting fully removed from memory despite trying both unloadchunk calls through bukkit. This allows one to shut down the server and continue restoration after a restart if one does not have enough RAM
    • /axr pack <world> - removes dead space in ore file (not that there is much from just mining but the axr chest will create significant amount of dead space.
    • /axr backup <world> - backs up the ore file of the world if and only if the file passes the corruption test, also packs the new file.
    • /axr test <world> - test the ore file and memory for errors for a specific world
    • /axr test - test the ore file and memory for errors for all worlds
    • autorepack config option - pack ore files automatically at startup (if and only if the file passes the corruption test) - on by default
    • autobackup config option - backup ore files automatically at startup(if and only if the file passes the corruption test, and also requires autorepack) - on by default
    • new .ore extension for ore files (rename your old files)
    • removed glowing redstone ore from default ore list (never occurs naturally anyway)
    • fixed faulty scanning issue
    • fixed hopefully last exposed ore face index error
    • fixed false positive in memory check
    • debug.log flushed when error occurs (it is otherwise flushed once in a period of time)
    • more details in debug log when error occurs
    • removed lindex spam in debug log until lindex error occurs
    • Fixed /axr gen not triggering scan anymore
    • Fixed /axr gen not unloading chunks
    • Fixed (workaround) huge memory leak during /axr off /axr show /axr hide and /axr gen caused by bukkit's unloadchunk function
    • Additional file corruption checks that will make noise as soon as something goes wrong
    • Fixed another potential index derangement bug.
    • Fixed array out of bounds exception during previous fix
    • Fixed a couple of bugs offsetting exposed ore face indicies when mining adjacent block potentially causing array out of bounds exceptions at a later stage and the revealing of wrong ores when exposed to light.
    • Added debug logging of exposed ore face indices when found, as well as fault intolerant check that will warn you about any corruption of the indices after the event.
    • fixed half of ore not being hidden when a chunk is generated on load.
    • removed various unnecessary details to be logged in debug.log
    • fixed bug restoring ore, hiding and showing in wrong world
    • revert hack to set block material of a chunk to physical updates due to lacking javadocs to figure out what function to call
    • Switched to non physics updating block material setting hack
    • Updated to #733
    • Added detailed debug logging of background processes.
    • removed logging of filepointer
    • fixed failed scan after /axr gen unloading chunks that were originally not loaded, consequently also /axr gen causing server to freeze and timeouts on clients.
    • fixed /axr gen not unloading chunks that were originally not loaded
    • /axr gen and /axr gen copy now actually usable
    • ore in stone filter now also applies to /axr off and /axr show (not just when it is found by light detection)
    • added /axr gen command for generating a rectangular area of chunks
    • added /axr gen copy command for generating all chunks that are registered in another world
    • Configuration option CFGfilterorenotinstone implemented, that allows filtering of ores not in stone (can be useful in recovering lost ore from a world with the same seed)
    • fixed ore regen not working when axr is off in that world
    • removed physics lock spam
    • fixed more concurrency errors during background processes (hopefully for the last time)
    • fixed more concurrency errors during background processes
    • fixed concurrency errors during background processes
    • fixed debug off in config file causing unable to start (again! although different place now)
    • ore stats dump - listing all chunks ore counts into a text file
    • ore stats diff - showing difference between two ore stats dump files (these two tools are useful if you are worried that your ores might disappear)
    • show command - reveals the ore but does not unregister them or delete the file
    • hide command - hides again ore that was revealed with show.
    • show, hide and ore stat dump are background processes that does not freeze the server.
    • axr off is now a background process
    • load percentage of background processes can be configured
    • specify map zoom and center
    • Fixed file index debug listing not showing
    • file index debug listing can be turned off in config.txt (fileindexdebug)
    • area regeneration functions now tolerate any two coorner in rectangle in any order.
    • fixed debug off in config file causing unable to start
    • added axr map command for showing map of loaded chunks
    • fixed light expose unmapped material (probably why you got grass/smooth stones)
    • fixed light expose restored block being block at exposed face
    • fixed light expose no chunk location offset (why you got it at spawn)
    • fixed exposed face location wrong axis (probably floating blocks)
    • removed unnecessary cacheing of chunks at startup by not using chunks as keys for file index(probably solve memory problems for large worlds)
    • bypassing unnecessary cacheing of blocks using minecraft hackery.
    • revised scan algorithm, bypassing bukkit wrapcode resulting in at 5-10 times faster scanning.
    • fixed queries on unloaded sidechunks during scan resulting in loading and even generation of chunks that on top of it due to eventlock get ignored by onChunkLoad, thus leaving chunks of unhidden ore.
    • fixed light expose filling 0s after removed index
    • probably more bug fixes, can't remember them all
    • world statistics: type axr world - shows also what worlds are on/off
    • chunk statistics when axr is off no longer causes world to be registered without any chunks being loaded
    • axr on doesn't show NaN when there is nothing to hide
    • proper colouring
    • empty chunks are no longer ignored.
    • Fixed potential ore type shift bug
    • Moved listindex before file is loaded so debug info can be displayed even if it crashes while loading.
    • added rectangular area regen functions
    • Fixed silly nullpointer exceptions
    • Specify what worlds to turn on and off
    • Specify what worlds to load at startup
    • option to keep all ore data in memory
    • chunk statistics (useful for checking that your ore doesn't disappear or duplicate)
    • chunk regenertaion (restore a chunk to state at world generation)
    • chunk ore regenertaion (restore only ore)
    • Fixed some other bugs related to exposed-face-to-ore index
    • Index debug file working again (it was still expecting 0.1.5 files)
    • Added potential ore file corruption warnings to debug file output
    • Fixed bug locating exposed-face-to-ore index elements having no array bounds check.
    • Fixed bug exposed-face-to-ore index elements not being removed
    • Fixed bug exposed-face-to-ore index not being updated when ores are recovered and removed from hidden ore list (new bug in 0.2)
    • Fixed bug at y levels above 128-16 looking for ores above the map
    • Uses NSCommand now (it did right from the start but its now a separate plugin)
    • auto-creation of config files
    • defaults to ops only when permissions is not present
    • Light detection optimization based on a separate list of faces exposed to nonsolid materials (this might not work with all materials yet such as stairs and singlesteps, but its not like the world generator puts them in the caves anyway) resulting in at least 10 times faster execution of light checks. This should reduce all lag that's not due to scanning new chunks for ore.
    • Once again more detailed debug log
    • Fixed bug in ore restoring function causing large veins of ore to be generated out of nothing
    • More detailed debug log
    • Removed file corruption check that's hogging up some cpu cycles during file load and write events (the latter occured during scan event) - so this should speed up scan events.
    • pseudo error "load error 1" moved to debug log.
    • Added 1 tick delay of scan in onload event since it appears bukkit fires it before the chunk is populated with ore. This fixed the bug of ore appearing if you teleport or walk far away from initially scanned chunks.
    • removed physics event logging since it appears to always be neglible.
    • Added message at startup informing you about the waiting time of scanning all loaded chunks may take a while.
    • Fixed bug starting server without plugin data folder causing it unable to write debug file
    • Added more debug file details (when its scanning, loading from file, or just loading from memory when neither is shown)
    • Those who who don't hide coal, should experience faster chunk scanning now
    • Fixed bug due to player location being null for some weird reason
    • Added debug logging of time spent on the main time consuming procedures.
    • Fixed config file not loading properly
    • Removed wtfexception spam
    • Initial Release

    You didn't back up your map?

    Well I did.. I backed it up when i installed antixray. =x and now its been sometime since then... all was working so I had no reason to keep making backups of it but now.. I forgot about the plugin and I updated to 1.7.2 which resulted in ores being removed completely. Only reason i turned off anti-xray is because I was mining for SO long and found nothing but stone... which made me think the plugin had broken then I realised we had updated to 1.7.2 so I think that caused the plugin to break and now it don't work. =x

    I used a recovery method in the main post by the author, which recovered SOME of the ores... but there are still places with no ores =x better than nothing I guess though. I wished this plugin worked perfectly and without any possible loss of data. It would be so great to play knowing that eveyrone here got the items they have, through hard work and not cheats =x

    Would love to see this updated soon. :) has rather bad issues with new chunks and causes some errors.

    I also have giant areas with no ore. I need an update just so I can fix the problems lol.

    same problem here, some ores are not hidden, my map is fully explored and border limited, so why it don't hide all ores ? hmm

    15 seconds of nonstop lagspike to load the plugin, can u PLEASE set it to a async background task to finish so the server wont lock up completelety on a reload/startup until this is complete?

    Kinda like how dynmap's /fullrender command works I'd assume.

    Hey man, any chance you'll still be implenting this? I very much would like to see this be implemented!

    If you need any help, I can do anything to help you. Can test as much as you want at any time you want me to. Pm me you think you can use me.

    Show Spoiler

    Worked for recovering the ore. I had to make sure the number of chunks regenerated would fit in the amount of ram allocated to the server though. I think the limit for me was around 30k chunks.

    thank you for the plugin!
    I thought it was laggy so I installed it for like 10 min,
    after the knew it they could use xray I had to put it on again for my survival map :p
    thank you ;)!

    @asdaarg The plugins works, except it spams the command promt while ym server is running with errors every like 15 seconds.
    Also with this plugin when I try and do a server reload, by doing /rel, it now disconnects people and the server takes like 1 minute to reload when it was only 10-20 seconds before? Is there any way of solving this? Because this plugin is amazing besides my problems!
    BTW this is what it spams:

    Can you add support for dungeons as well? Other anti-xray plugins don't seem to address this issue. Players have been using this to locate dungeons and abuse my server's Iconomy.

    I typed :

    /axr on
    /axr hide
    and /axr hide world

    but for some reason it still shows the ores. Could someone help? (I set debug = false) and also it showed it hiding ores with the 0/2417 - > 647/2417 and then hidden all of them, yet people can still use it.

    Anyone have some advice?

    This plugin blocks xray texture packs completely, but unfortunately, does absoloutly nothing to stop the xray mod. -_-

    The zombe hack mod for example, is untouched by anti-xray

    Hi guys and gals ...

    I just can not get the /axr commands to work ...
    it always says "unknown command"
    the NSCommand.jar is in the lib folder

    our server seriously needs help to restore the ore in new generated cunks
    but without those commands that wont work ...
    and a backup is no option because the lastbackup without axr is to old
