    Using LWC

    [​IMG] Modules
    Modules are seperate plugins much like LWC but extend LWC in some way, usually by giving extra functionality. While there may be more than already listed here, these modules are ones that are officially supported by LWC and maintained by the same author (Hidendra).

    [​IMG] LWC-Economy 1.30 - [​IMG] Download
    Configuration file: plugins/LWC/iconomy.yml

    LWC-Economy allows players to buy protections with economy money. At the moment, iConomy, BOSEconomy and Essentials are supported (have an Econ plugin that you want supported? PM me!) It can be configured on a per-user and per-group basis. It does not use Register.

    Aside from purchasing, when a user removes a protection, they will also be refunded what they initially paid for the protection.

    Discounts can also be given to each individual group, player, or by default. A discount is defined by giving X amount of protections for Y price, e.g 5 protections for free (0). After getting 5 protections for free, they pay full price again. They cannot get another discount again unless one of the following becomes true: a. an admin manually resets them b. the discounted amount of protections is increases (e.g increasing from 5 to 6 will mean said player gets 1 more for free) or c. the discount price itself changes (which means they will again get 5 protections for the new price.)

    What can be protected?
    • Chests
    • Dispensers
    • Furnaces
    • Doors
    • Signs
    • Trap doors
    • Anything else! Protections can be customized to anything you wish.

    • Plug 'n play! LWC handles all dependency resolution -- you just put LWC.jar in your plugins directory
    • Has reached a level where its routinely safe and stable.
    • Protections can be: Public, Password, and Private (by User and/or Groups)
    • If the block has a persistent inventory (ex. chest), LWC can protect it! (Unless the server owner disabled the protection of a specific block!)
    • Limits of how many protections a user or group can lock
    • Small memory footprint. No flat files.
    • For chests, only 1 side of the chest needs to be protected. The plugin saves space by dynamically linking connected chests as protected
    • Much, much more. This post would be extremely long if I were to post every feature LWC has to offer.


    If your server would benefit more from a version of LWC in your native tongue, or you just want to do it because LWC is awesome, I'm open to allow translations to (almost any) language. Almost all LWC messages are editable.
    Locale files can be UTF-8, but are limited by Minecraft's charset (Latin-1.)

    The current and latest English locale can be found here:

    Currently, the following languages are officially bundled with LWC:
    • German - de - @Dawodo
    • Polish - pl - @Geoning @dudsonowa and @andrewkm
    • French - fr - @Cehel
    • Dutch - nl - @MadZero & @aoa2003
    • Czech - cz - @hofec
    • Swedish - sv - @christley
    • Russian - ru - @IlyaGulya - requires a Cyrillic font mod for the MInecraft client
    • Spanish - es - Raul " @RME " Martinez & David " @DME " Martinez
    • Danish - da - @TCarlsen

    • NEW: Refunds can now be disabled by making iConomy.refunds false

    LWC 3.42
    • The flag "EXEMPTION" has been added to allow you to exempt flags from commands such as ADMIN PURGE and ADMIN EXPIRE; it prevents the protection from being removed unnecessarily. It can only be activated by LWC admins. Use /cexempt on or the usual /lwc flag exempt on
    • FIX: Some servers were experiencing a freezing issue on startup which is now fixed
    • FIX: Disabled modes were not properly disabled, despite being told the mode was disabled.

    LWC-Economy 1.21
    • FIX: On some servers LWC-Economy would not bootstrap itself into LWC correctly
    • LWC is unaffected, but due to how automatic provisioning works, the binary will be different from the last due it modifying the build number in /lwc admin version

    • FIX: Servers with autoUpdate set to true would find 3.40 would crash all of the time due to a stackoverflow exception.
    • FIX: PermissionsBukkit /permissions command was unusable due to LWC making it load when the server first started, not when it normally would.

    LWC-Economy 1.20
    • LWC-iConomy.jar has now become LWC-Economy.jar -- please update accordingly.
    • BOSEconomy is now supported alongside iConomy. No extra setup is necessary for either!
    • Money paid for protections can now be refunded when you destroy the protection, even if the person who paid (the owner) is offline.
    • Discounts now give out the exact amount of protections for the discounted price. For example, if 'newCharge' is set to 0 and 'amount' is set to 5, a player will be able to create 5 protections for free after it takes effect.

    LWC 3.40
    • Almost all current LWC Module events have been deprecated. They have been replaced with events such as: `onProtectionInteract(LWCProtectionInteractEvent event)`
    • Fixed PermissionsBukkit compatibility: some commands did not work correctly
    • `/lwc admin cleanup` has accelerated to warp 5
    • Servers without any Permissions plugin would find anyone would have LWC Admin access
    • The mode "nospam" has been added to prevent protection creation messages from popping up (e.g "created protection successfully.") Use /cnospam or /lwc mode nospam, which toggles it on and off.
    • Protection history. LWC now logs all protection creations/destructions -- in the future, this may log chest access, but if it happens it will be a separate plugin such as LWC-Economy
    • -remove flags have been added to `/lwc admin expire` and `/lwc admin purge <player>` to remove the associated protection block. For example, if you use `/lwc admin purge -remove Hidendra`, it will remove all protections by Hidendra, and also all of the blocks protected in the world, along with any chest contents.
    • If LWC loses connection to MySQL, LWC will prevent access to chests until the connection is regained. This is to prevent stealing from chests if the connection is somehow lost and cannot be immediately regained.
    • Pistons can no longer destroy protected doors and so on.
    • Multitude of bug fixes and minor corrections
    • Minor optimizations

    • PermissionsBukkit is now officially supported. LWC will still work on builds pre-1000
    • lwc.blockinventory has been renamed to lwc.deny - please take note
    • Fixed a bug where protections would be loaded from any world
    • Fixes to the Danish translation

    • Added core.ignoreExplosions to core.yml to allow an admin to allow creeper explosions / TnT to destroy protections
    • Protections will now keep track of the last time they were interacted with
    • Added the command /lwc admin expire to allow you to expire protections that have not been used in so long. Example: /lwc admin expire 2 weeks
    • Added the command /lwc admin purgebanned to remove protections of every played in banned-players.txt
    • Added the command /lwc admin query to allow raw queries on the physical database
    • Drop transferring could not be disabled, it is now fixed.
    • Various bug fixes

    • Fix "fetch size" error
    • Removed the auto-removal of the very old players table


    • Very important bug fix for those who are using MySQL and prefixes. Prefixes will now work correctly and any issues arisen from MySQL usage should now be resolved
    • Fixed lang-defined block names being used in core.yml - protections instead of the english variant, otherwise all protections are broken.

    • It's not all about me! I've tried my hardest and /lwc credits was the result. It turns out there is a lot more people I am extremely thankful to than can fit on one chat page, so instead it scrolls.
    • Many, many people helped with LWC in vastly different ways and it's impossible to credit every single person accurately, thus I missed a few people.

    This update introduces three more languages: Russian, Spanish, and Dutch.
    • Russian - @IlyaGulya - requires a Cyrillic font mod for the Client
    • Spanish - Raul " @RME " Martinez
    • Spanish - David " @DME " Martinez
    • Dutch - @Tcarlsen

    Chunk corruption workaround
    • Have you ever noticed, when you /cinfo'd something, it said "That air is not registered"? Or when chests randomly stop working? If you get this a lot, you are most likely affected by an issue in Bukkit where chunks will mysteriously report Air (or some other block) for each block in the chunk. Please refer to this bug report on Leaky Bukkit:
    • @morganm graciously found a way to workaround this issue, and it involves forcing every single protection to be cached and some other magical tidbits (without getting too technical.) To enable this, open up plugins/LWC/core.yml and then change bukkitBug656workaround to true. If you don't see it under core:, add it:
          bukkitBug656workaround: true

    • Trap doors are now available as a default protection for any new configurations: they will not automatically add themselves to existing LWC configurations
    • The default value for magnet.yml - perSweep has been changed from 20 to 40
    • The command /lwc debug has been added to test your permissions and show you precisely what you have access to
    • LWC now displays the git commit and Jenkins build ( in version strings (e.g /lwc admin version or /lwc admin report).

    • Translation: Swedish! Thank you @christley!
    • Bug fix for block placement

    • Translation: Czech! Thank you @hofec
    • The default value for core.showMyNotices has been changed to false (does not affect current installs.)
    • Burning furnaces have been fixed
    • Iron doors have been fixed
    • Redstone fix
    • Fixed auto register allowing registrations without having lwc.protect
    • Feature: auto openable Iron Doors. On by default -- iron doors (including double doors) will open (or close) when you click them provided they are both protected and you have access to them. "openAndClose," which closes the door automatically after x seconds (3 by default) is available but currently may not work as expected (works oppositely for doors facing North or South; doors will stay open.)
    • Trap doors (aka hatches) have been added to the default protection list. However, if you have an existing core.yml, and want trap doors, you either need to delete core.yml and restart the server (thus redownloading it) or adding trap_door to protections.blocks, e.g
                  enabled: true
                  autoRegister: off

    • Sign names have been normalized to "Sign" (e.g Wall sign and Sign post are shown as just Sign)
    • Added locale values for "you" and block names (chest, furnace, dispenser, wooden_door, iron_door, and so on.) Custom block names can be defined if you have custom protections.
    • Dutch translation -- thank you to @MadZero and @aoa2003

    • Notices will be shown correctly to admins when showMyNotices is disabled.

    • Limit the amount of queries the Magnet module can use (can be changed with magnet.perSweep, default 20. Delete magnet.yml to auto-regen it). On larger worlds, this was a severe issue
    • magnet.enabled now works correctly

    • MySQL prefix is now working as it should
    • Minor fix with the cache update in 3.02

    • Cache null protections as well, to prevent massive redstone spam

    LWC 3.01

    Thank you so much to the many, many people who provided feedback and suggestions on 3.00.
    This changelog may be incomplete as I probably missed some obscure changes.

    The following languages are now available in LWC:

    Lists support
    • LWC supports the Lists plugin which allows you to create a list for your protections to use. Anyone in this list attached to the protection can access your protection
    • When modifing/creating the protection, use l:ListName or list:ListName, e.g: /cmodify l:Test or /cprivate l:Test

    • is now gone. It has been replaced by multiple .yml files, e.g core.yml, limits.yml, worldguard.yml, and so on.
    • Your old is still automatically converted.

    • The old in-database limits has been fully removed. It is replaced by an on-disk alternative, limits.yml. This very easily allows much more in-depth limits management (e.g only: 5 chests, 2 furnaces, 0 doors)

    Custom protections
    • It is now extremely easy to create your own custom protections, or remove existing ones (core.yml -> protections:). For example, this is how you would make Note Blocks protectable, and allow people to play them (But not change the note!):
                enabled: true
                ignoreLeftClick: true

    • [I hope] final major revision to the LWC Api. New additions will allow other plugins to hook into LWC much more easily and do things that were not possible before. Features can be seamlessly integrated into LWC as if they were in LWC itself.
    • PhysDB.getPrivateAccess is now deprecated -- please use protection.getAccess instead!
    • Protections can be more easily modified utilizing methods in their objects: save() (queued save), saveNow(), remove(), removeCache() (just removes the protection from the cache, not the database), and update() (just updates the cached protection, save()/saveNow() already does this)

    LWC Modules
    • Modules can be thought of as a plugin inside LWC itself -- more or less they will change LWC's behaviour in some way, depending on the module.
    • Very easily implemented by developers: cancel protection registrations, cancel that damn protection message, and way more! More info on the wiki.

    Admin customization
    • There are now a ton of permissions nodes; there is one for each admin command. For example, for every Admin command, you could use: lwc.admin or lwc.admin.*. For just "find" and "forceowner", you could give a group/player the following: lwc.admin.find and lwc.admin.forceowner. Full list on the wiki.
    • Please note that lwc.admin.* only grants all Admin commands; lwc.admin still has a higher authority over the former (e.g, lwc.admin is considered the owner of any protection, while lwc.admin.* is not !!)

    Player customization
    • Like the admin commands, the main LWC commands can now be customized via permissions. lwc.protect still functions the same (all functionality); some examples of new nodes are: lwc.create or lwc.create.* (create anything), lwc.create.private (only be able to create private protections), (/cinfo), lwc.modify (/cmodify), lwc.unlock (/cunlock), and so on. Full list on the wiki.
    • Please note that without lwc.protect, you need to manually assign flags. E.g: lwc.flag.* or / lwc.flag.magnet

    Magnet flag
    • The chest will act as a magnet and suck up nearby items (within a 3 block radius.) This can be very useful for automatic farms (e.g animals or crops.) It is compatible with double chests.
    • Can also specify items that these special chests will not pick up (in magnet.yml)
    • Compatible with Double Chests

    • It is now possible to sell protections with the fully optional LWC-iConomy bridge module. You just throw LWC-iConomy.jar into your plugins folder and then edit iconomy.yml in plugins/LWC/ when it's generated on the next startup!
    • You can also allow players to have a certain amount of protections at a reduced price (or even free) e.g free protections while you have less than 5 (but regular price after that.)

    • LWC now does major caching of protections in memory. Previously, LWC hit the database everytime a protection is opened; now they are routinely stored in cache without a huge hit on memory usage (very minimal.) It can be increased from the default of 10000 if you wish in core.yml (core.cacheSize). More will most likely be cached in the future
    • Access rights are now stored with Protections (for the curious, it uses an OUTER JOIN, so just 1 query.)
    • Protections are precached (as many as possible) when the server is started
    • Lots of bug fixes (mostly miscellaneous.)

    • MySQL prefix can now be configured (if you change it with an existing MySQL install, it will fix that automatically, don't worry!)
    • /cpersist or /lwc mode persist now acts as a toggle for the mode
    • Added the following aliases: /cpersist , /cdroptransfer , /cmagnet , and /cadmin
    • /climits displays your protection limit and how many protections you have protected.
    • Minor changes all around


    • Security bugfix regarding an issue in minecraft itself (thanks sycot)

    • Native German translation! If you wish to use LWC in German, please change "locale" in to de. Many thanks to @Dawodo for doing the translation!
    • /lwc admin cleanup will now show the correct values instead of variable names when outputting results
    • enforce-worldguard-regions is now compatible with WorldGuard 5.x
    • Redstone is now changed again. All set redstone flags are reset. Redstone will obey the deny-redstone config value (which is false by default), meaning if it is set to false, you need to explciitly set the flag to disable redstone (/lwc flag redstone on), and if it is set to true, all doors prevent redstone by default so you need to set the flag to allow redstone.

    • Minor bug fixes

    • By default, redstone WILL NOT open doors (at the moment, it appears dispensers are unaffected, hopefully they will be fixed in CraftBukkit). In order to allow redstone to open your door, you need to issue this: /lwc flag redstone on. Using /lwc flag will show you the available protection flags -- these are "switches", only on/off (only redstone flag exists at the moment)
    • Bug fix: Protections will auto protect themselves again when being placed

    • Official support for RB builds >600 now that I am back home
    [hit max thread length]

    enjoy, gents

    Fix the dupe exploit already.... 4.2.1 Still has it.

    Does someone now which permissions are necessary to allow someone to use logblock tool on a locked chest?
    Since 4.1.1 I believe, locked chests can not be queried by logblock tool anymore with only the lwc.protect permission. It only says: "This chest is locked."
    Only OPs or Admins with all permissions can query them, and the wiki is down atm. So I can't look up the permissions...

    [LWC] Critical Error. Please contact instantly an admin. ID: PLAYER_INTERACT
    And at the console:

    I have a suggestion.Maybe make it so that ONLY u can open the chest and other things instead of u and the ops being able to open the chests. But other then that great plugin!:)I said this because i am sick of my friend who's an op opening the chests in my shop and taking stuff.also try to make it compatible with permsex whenever i try to use it with permsex it always sez that there is an lwc error please notify a admin:player interact. If you know how to fix this please help me.:(

    I get an error code like the one that truekhulie got when i used it with permsex can you tell me how to fix this. I know deleting permsex will fix it but still i want to have a permissions plugin like permsex. it is really easy.

    Great plugin, have been using it for quite some time now. How ever it is possible to dupe items by using the magnet flag. Any way to disable the usage of flags? Or to disable the magnet flag?
    EDIT: Nvm, it seem to be fixed in the latest update.

    Ok so I put the lwc.jar in my plugins folder and I have craftbukkit r4. I started my server and it created the files necessary. but my server wasn't showing as online and in console it would scroll through the startup messages then get to connecting to sqlite or something then it would go through the same startup messages again and it would just repeat but never start up. I tried restarting but it still didnt work. So I deleted the Lwc folder and jar but the lwc folder stayed and couldnt be deleted but all it had in it still was lib, and in lib is native, in native is linux, and in linux is amd64. And in amd64 is nothing. Those folders can't be deleted. Now i just tried to redownload lwc, it creates the folders inside LWC folder, but it doesnt create anything in the lib folder. What is wrong?

    Excellent plugin, Essentials [Private] signed ceased to work, this is a major step-up from that. Good work.

    I'm running a modded server and i have a question. i have a mod that adds 6 chests under one id but different damage values, if i set the configuration file to protect the id that they are all under would it work to protect all of then, or just the base? Ex: iron chest 181, gold chest 181:1

    I'm having trouble downloading sqlite,jar and sqlitejdbc.dll when I run LWC for the first time. Can anyone provide a manual download link for the 2 files? Thanks.
