    AntiXRay
    Version:v0.6.10

    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



    Description:

    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.



    Downloads:
    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
    AntiXRay
    Source and old versions

    Features:
    - 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.

    Commands:

    /axr on - hides all unlit ore
    /axr off - reveals all hidden ore (and deletes the data file!)
    /axr on <world> - hides all unlit ore in specified world
    /axr off <world> - restores ore in specified world
    /axr worlds - world statistics
    /axr chunk - chunk statistics at chunk player is on
    /axr chunk <x> <z> - chunk statistics at specified chunk
    /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 map <world> <x> <z>
    /axr map <zoom> <x> <z>
    /axr map <world> <zoom> <x> <z>
    /axr show
    /axr show <world>
    /axr hide

    /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.
    Auto-backup, that will backup your ore file on startup
    /axr backup <world> - backs up the ore file of the world if and only if the file passes the corruption test
    /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
    /axr mirrorworld <world1> <world2> - creates a world world2 with the same seed as world1.
    These functions are not recommended for use unless you know what you're doing: (they can be destructive of tile entites)
    /axr chunk regen - regenerate chunk (to as it was when world was initially generated)
    /axr chunk regen <x> <z> - same but for specified chunk
    /axr chunk regen <x1> <z1> <x2> <z2> - same but for axis aligned rectangular area
    /axr chunk regen ore - only regenerate ores in chunk at player position
    /axr chunk regen ore <x> <z> - same but for specified chunk
    /axr chunk regen ore <x1> <z1> <x2> <z2> - same but for axis aligned rectangular area

    Note about regeneration: ores, trees, flowers and mushrooms are random each time and not tied to world seed (bukkit/mc issue)

    v0.6
    • /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

    • 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
    v0.5.21
    • Fixed /axr gen not triggering scan anymore

    v0.5.20
    • Additional file corruption checks that will make noise as soon as something goes wrong
    v0.5.19
    • Fixed another potential index derangement bug.
    v0.5.18
    • Fixed array out of bounds exception during previous fix
    v0.5.17
    • 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.
    v0.5.16
    • fixed half of ore not being hidden when a chunk is generated on load.
    • removed various unnecessary details to be logged in debug.log
    v0.5.15
    • 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
    v0.5.14
    • Switched to non physics updating block material setting hack
    • Updated to #733
    v0.5.13
    • Added detailed debug logging of background processes.
    • removed logging of filepointer
    v0.5.12
    • 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.
    v0.5.11
    • fixed /axr gen not unloading chunks that were originally not loaded
    v0.5.10
    • /axr gen and /axr gen copy now actually usable
    v0.5.9
    • ore in stone filter now also applies to /axr off and /axr show (not just when it is found by light detection)
    v0.5.8

    v0.5.6
    • fixed ore regen not working when axr is off in that world
    • removed physics lock spam
    v0.5.5
    • fixed more concurrency errors during background processes (hopefully for the last time)
    v0.5.3
    • fixed more concurrency errors during background processes
    v0.5.2
    • fixed concurrency errors during background processes
    v0.5.1
    • fixed debug off in config file causing unable to start (again! although different place now)
    v0.5
    • 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.

    • load percentage of background processes can be configured
    • specify map zoom and center
    v0.4.1
    • 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
    v0.4
    • 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
    v0.3.3
    • world statistics: type axr world - shows also what worlds are on/off

    • added rectangular area regen functions
    v0.3.1
    • Fixed silly nullpointer exceptions
    v0.3
    • 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)
    v0.2.5
    • 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
    v0.2.4
    • Fixed bug locating exposed-face-to-ore index elements having no array bounds check.
    v0.2.3
    • Fixed bug exposed-face-to-ore index elements not being removed
    v0.2.2
    • 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
    v0.2.1
    • 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
    v0.2
    • 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
    v0.1.5
    • Fixed bug in ore restoring function causing large veins of ore to be generated out of nothing
    • More detailed debug log
    v0.1.4
    • 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.
    v0.1.3
    • 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
    v0.1.2
    • Fixed bug due to player location being null for some weird reason
    • Added debug logging of time spent on the main time consuming procedures.
    v0.1.1
    • Fixed config file not loading properly
    • Removed wtfexception spam
    v0.1
    • Initial Release
    Donate (Not necessary but appreciated)

    something that isn't there can't load stuff...
    so probably you just messed up your map. Probably did somethign wrong with one of your plugins. This dosn't sound plugin relatet to me at all. I'm using it and experiencing not a single bug and i also us about 26 plugins...

    Did you restart/reload the server? Deleting the plugin from harddrive wont remove it from physical memory. To do that you need to restart or at least reload the server.

    No success. I even updated to 0.1.5 and removed the config.txt file. Getting the same issue. Now reloading plugins or starting up the server locks it up so I have to force close it.

    I uploaded the server.log with the spots I tried something different. I also snipped out all the other garbage.

    yes i restarted the server and reloaded alot of time, servercraft is the host of this server so i dont have any controll over the ram so i cant refresh ram, i wrote them a ticket on this plugin tho, also geting my old files back, that this plugin corupted, ill ask for an error report so you can see l8ter

    i also need to force it to close it :S

    @asdaarg: Are you going to add per-world on/off switches? Or could you put it on github so I can hack it in for me (while keeping track of your changes)?

    I actually had the debug off on that run. Sorry, I got it running just enough to /axr off and have it reset ores, so I could remove the plugin for now. I can do other testing if you wish?

    i cant run it because some people like mining in the dark and say its a waste of coal any ideas?

    asdaarg

    Yes, debug.log would be helpful. No it puts everything in the AntiXRay folder.

    Yes, although there isn't anything specific I want to have tested, just whether it works as it should, that there are no bugs with the ores appearing where they shouldn't or ores not appear where they should, or other errors occuring. If you have a transparent texturepack or even the Xray mod or something of that sort would help in testing.

    Something I would also suggest, and I think its this way unless you tell me otherwise. The debug log should probably be rolled per server run, so it doesn't grow overly large.

    That's something I never understood. There's tons of coal everywhere and its a pain to do anything in the dark.

    Hey, I would love to implement this onto our server but I would only be able to do so if it 110% no longer has any chance to delete all the ores across the map - has this bug been fixed completely?

    I know with the plugin PreciousStones you can "cloak" blocks to make them LOOK like a block near them - I imagine this is what this plugin does... with preciousstones however, there is a glitch where it will permanently change the cloaked block.. I imagine its the same bug here, heh.

    I don't think any ore deletion has happened since I released the very first version. Although people have reported that ore appears out of nowhere, and that got fixed as well, but there could always be a bug somewhere hidden, so there is no guarantee. Just backup the world and see what happens if you want to try it. The only issue now seems to be lag, and that will be reduced in the version.

    2011.04.13 05:01:58 Periodic light check[133┬Ás]
    and this down at diamond level :D At least 10 times improvement considering I got 10 times higher at the surface before :)

    If anyone just downloaded now, try again, because I forgot to change the link, so you've got 0.1.5.

    If I delete the AntiXRay folder in my plugins folder, it won't delete all my resource, right?

    Yeah... I'll just stick to logging diamond breaks with plugins like FoundDiamonds. This plugin is a bit too risky.

    Nate204

    True.

    I just searched for 10 minutes, and I can't find a single ore.... -.-;

    Time to load a map save.
    Why would it be that way? Can't it be configured to only enable this switch if the plugin is present.

    I think you have to /axr off first before removal. Thats what I did, I just had to let the server run till it got booted up.
    I did a little checking with worldedit //chunk and //distr and things seemed to be ok.

    Amazing sounding plugin. But how well does it work on large servers. I wonder what happens to things like iron ore under minetracks? It sounds like you can set the ore type so that is pretty neat.. Spawners could be added then this might be pretty damn cool. But I still worry about it damaging things...


    If anyone running this on large servers and experience no lag let me know what settings and methods your doing. I assume since Iron/Gold are sort of common most will do diamonds / Mob spawners

    If they are lit, or built after the initial scan they wont be hidden. Otherwise they will become visible when they are first lit or a nearby block is changed or removed. There may be a few exception, since not all transparent blocks are letting through light. Those ores will not disappear though, just remain unhidden til you find it by changing a nearby block or til I update the visibility system somehow, or notch or bukkit team changes the behaviour of lightblocking transparent blocks.
    Spawners have additional type info I think, and dungeons are easily visible as large boxes anyways even with transparent texturepacks, or the sand glitch.
    Removing coal could speed up things. However with the last update, it should be speedy enough even for coal. But I'm still waiting to hear the result of people testing it out.

    Although there was no explicit uninstall instructions, it should have been obvious from "backup your ore files" and that "ore is stored in ore files" that you just don't delete them and expect them to be back, but anyways I added explicit uninstall instructions now.
    I might even add an option to let people regenerate their chunks (that they haven't built on) if they do this accidentally and want to restore it.

    Looks ok to me, decent scanning times and light check times even though this is from 0.1.5 or earlier.
