    The active Lockette information page will commute to BukkitDev soon, but the forum thread is still the best place for discussion.


    The purpose of this plugin is to restrict access to the contents of chests, dispensers, furnaces, and doors without the use of a database to track containers.

    To use, simply place a signpost on the floor directly beside a chest or other container to be locked. Enter [Private] as the first line. Your own name will automatically be entered on line 2 as the chest owner. Optionally type in the full names of two other users allowed to access the chest's inventory on lines 3 and 4.

    When done correctly, the sign will automatically fix itself to the side the target chest, protecting it from unauthorized access! Only the chest's owner can then break the sign or chest. (Warning: Anyone with permission to use WorldEdit commands or similar can circumvent the protection by removing the sign.)


    Additionally, you can enter [Everyone] on lines 3 or 4 instead of a user name to allow everyone access to the contents of a private container, or [Operators] to allow ops access. If a Permissions plugin is available, you can use groups like [Moderator] or [Admins] or others as defined in the Permissions settings files.

    The owner of a container can add more users by placing additional signs beside the container with the heading [More Users], where lines 2-4 specify the names of the additional users. You can edit the users on previously placed signs by right clicking the sign, and using the command '/lockette <line number> <text>' to change it.

    Working with Doors:

    To protect a door, you can use the same method as protecting a container, the sign will attach to the door automatically. In addition, you can attach a [Private] wall sign to any side of the blocks just above or just below a door. For double doors only one side needs a sign. Door support is enabled by default in the config file.

    Once a door is protected it will only open for someone listed as a user, and will not respond to redstone power or switches unless [Everyone] is listed as a user. Iron doors which usually won't open from clicking will work just as wooden doors. In addition, double doors will open together automatically!

    You can also use [More Users] signs as with containers, with the caveat that the sign cannot be placed on the block above the door if the [Private] sign is not above the door as well! (This is done to prevent a security uncertainty issue.)

    Protected doors will be closed automatically if a timer is set. A timer can be set globally with a configuration option, or individually for each door by using the tag [Timer: #] on line 3 or 4 of the [Private] sign, where # is the number of seconds that the door should remain open. If the timer is set to 0, this means the door will never automatically close. If no timer is specified, protected doors will use a global timer set in the configuration file. If the server is shut down cleanly any open doors will be closed, but in the event of a server crash while a door is open, it may remain so. Note that the initial state of a door is assumed to be closed.

    Care must me taken to place protected doors on a stable block. Building a door on sand, gravel, leaves, TNT and et cetera are allowed by the plugin, but cannot be secured fully. :3 Additionally, it should be noted that most status messages still refer to locked blocks as containers, so for the purpose of simplicity, doors should be considered as a type of container.

    • No passwords or databases needed!
    • Permission checks run in constant time, no matter how many protected containers.
      • One owner and up to 11 additional users supported. (17 for double chests!)
      • Allows access to [Everyone] while still protecting the container from vandalism.
      • Allows group names in conjunction with many other plugins.
    • Special powers for ops or admins, configurable with permissions.
      • Reports when an admin does something naughty.
    • Protects single and double chests, dispensers, and furnaces.
      • Explosion and block-break protection for the protected container and sign.
        • Option to protect all containers from explosions.
    • Full support for doors, both wooden and iron!
      • Double doors are handled automatically, with no redstone.
      • Doors can be set to close automatically, via a timer setting.
      • Redstone hacking is disabled for protected doors.
    • Prevents creation of chests larger than 2 blocks.
    • Informative or helpful messages when interacting with containers.
      • The first time a chest is placed, a help message will be shown.
      • Types of messages shown are configurable in settings.
      • Additional language support.

    Advanced Setup (Permissions) (open)

    Advanced Setup:
    There are a few things you can now customize in the configuration files for the plugin, found in the plugins/Lockette folder. After running the plugin for the first time, two files will be created, config.yml and strings.yml. The first holds the following settings:
    • enable-permissions - Allows the use of permission nodes to specify who can do what. If this is disabled, groups will still be used but admin status is taken from the ops file. Defaults to false.
    • enable-messages-* - Enables or disables groups of messages listed in the strings.yml file. Not counting the broadcast ones.
    • broadcast-*-target - Sets the group or player that specific broadcast messages should be sent to. This can be set to "" for no one.
    • explosion-protection-all - Enabling this extends explosion protection to all containers on the server, not just [Private] ones. Default is disabled.
    • allow-admin-bypass - Allows admins to go though any protected door. Default is true.
    • allow-admin-snoop - Allows admins to peek into chests owned by other people. Default is false, and this setting is recommended! A broadcast message will be sent each time an admin snoops in a protected container where the admin doesn't have permission to. The message will be sent to a player or group as specified in another option. Admins can still break protection on chests if this is disabled, however.
    • enable-protection-doors - Enables support for private doors, defaults to true.
    • default-door-timer - Sets the door closing timer for all protected doors on the server, unless overridden by a specific sign. Defaults to 0, which disables the door closing timer.
    In the strings.yml file, you can set alternate language tags for [Private] and such, in ANSI format. If you need characters not in ANSI then you might try UTF-8 format, though it seems bugged tight now. The default alternate tags are in French, but server ops are free to translate the whole file into the language of their choice. If you do this, please share it back to me~ :3 If you want to disable only a specific message, you can set it to "", the empty string. Admins can use the command '/lockette reload' after editing the configuration files, to reload them.

    If a Permissions plugin is not available or the enable-permissions option is set to false, Lockette will use the ops file to determine who are admins. Admins can break the protection on any chest, and look inside protected chests (only if the related option is set), as well as reload the plugins configuration files. All non-ops will be able to create protected containers for themselves.

    If a Permissions plugin is available and the enable-permissions option is set to true, the following nodes will be used instead of the ops file and are included by default in the '*' node:
    • lockette.user.create.* - Permission required to create a protected container or door. Possible sub-nodes include chest, dispenser, furnace, and door. (The permission lockette.create.all is still supported, but obsolete.)
    • lockette.admin.create.* - Allows admins to create containers and doors for other users. Possible sub-nodes include chest, dispenser, furnace, and door. Leave line 2 blank for the default behavior or enter the name of your choice. Capitalization matters.
    • lockette.admin.break - Allows breaking protection on containers.
    • lockette.admin.bypass - Allows opening of any locked door.
    • lockette.admin.snoop - Allows peeking in protected containers. (The setting allow-admin-snoop must be true.)
    • lockette.admin.reload - Allows use of the reload command.

    Technical Information (open)

    Technical Information:

    This plugin has been tested and shown to be working for many builds of CraftBucket though a number of the more recent builds had a serious issue, so I'm suggesting a minimum build of 561 now. If you update past what is listed in the post's title and the plugin seems to break, it is probably not my fault. Post a note anyway and I'll see about fixing. I'll try and keep up with the new recommended build system, but for latest builds that break things, you should expect some time to pass before I take care of the issue, as this plugin is now mature. :3

    If there are multiple containers by the placed sign, the plugin will use the NESW rule to choose the first container that is not yet private. To elaborate, the plugin will check to the north of the sign first, and if no container or door is available to the north, it will continue checking clockwise around the sign.

    Due to the current implementation of the explosion event, this plugin will cancel all explosions that would damage the container or sign, rather than just remove the container and sign from the blocks to be damaged. Canceled explosions still knock signs off the walls. Canceled explosions leave signs looking blank, but this is just a graphic glitch, reconnect to fix.

    Bonus: This plugin will prevent chests bigger than 2 blocks from being created via glitches. (Again, this could be circumvented using WorldEdit commands, so take care who has access to such a plugin.)

    This plugin was inspired by the old hmod plugins Lock by Roman "kingseta" Pramberger and ChestCapsule by Fernando "Fergo".

    Hooking into Lockette (open)

    Hooking into Lockette:

    If you are a plugin author and want to connect to Lockette, you can use a public static function to get information about the protected status of a block.

    More info later, perhaps, but if you need the details now then go poke through the source~

    Future Possibilities:

    There are a number of things that have been suggested, and they tend to be added to the list below if I think they might be a good idea. However, some sort of locked container limit is requested often but this is not possible without a database to track the number of locked containers someone has. All things considered, this will not be supported. On the up side, without a database you can have literally millions of locked containers without any sort of lag, and there are permissions to restrict who can create locked chests. Perhaps only allow Moderators to create locked chests for other users, if you don't want to allow infinite locked chests.

    Aside what has already been implemented, the following may or may not appear in future versions:
    • Furnace/dispenser clusters, protected by a single sign.
    • [Log] sign to list recent users of a container or door.
    • iConomy fee for protecting containers/doors.
    • Worldguard connection.
    • [Protected] tag for viewing only.
    • Specific time range that doors can be opened.
    • DataLog plugin support.
    • More types of protected blocks, such as brewing stands.
    If you want any of the above features sooner than never, let me know! However, I currently see Lockette as functionally complete, for the most part, in that it already has all the functionality it needs. Future updates will mostly be to account for changes in Minecraft and Bukkit.

    Could you give admins the option to snoop without the entire server knowing they did it? I check chests for hacked and stolen items and it's less than sneaky when it broadcasts what I did.

    See just above! :3

    It worked! Oh happy days! :D

    I put a sign next to a container saying [private] <name> under it, and it says (no container to claim or something like that) do you know what the problem could be?

    Acru i whitelisted you :D

    Are you using a craftbukkit build in the range 605-612? If so, upgrade~ If not, check sign placement location. (And btw, name is entered automatically.)

    Edit: :3

    When I lock a door with [Everyone] as a user, opening it gives me the door bypass message.
  10. Offline


    Acru, I know you said that its not possible atm to define how many chests each group gets, but do you know any plugins that do that?
  11. Offline


    Does LWC do that? I have no idea~

    Oh, wait, are you an admin and putting [Everyone] on the second line of a [Private] sign? That's not allowed, line 2 must be a valid user, the owner of the door. (Leave blank to have it fill in your name)

    Its okay, I hadn't considered that possibility when I added the feature~
    Perhaps I can catch bad names in the next version.

    Im an admin, but can not seem to look into other chests or open others doors. I have put into permisisons....

            default: true
                prefix: '&2'
                suffix: ''
                build: true
                - '*'
                - 'lockette.admin.*'
    But still not working.

    Well, local would be nice I guess some people may want a longer time before it closes automatically, the problem there is how each user would specify, now you could do something like [Private:8] which would be auto close in 8 seconds. Having a global config option would be best for now, maybe some ideas for per user times will come up in the future.

    That said, I seem to have found another [small] bug. With the new ability to claim a container for another user, if you put YOUR name on the first line, it claims the container for you, but for some reason you don't have access to it, and if you're admin with permissions you get snooping messages.

    EDIT: Reading over what I've just said, maybe, global config option, which is the default [Private] = default auto close [Private:0] = no auto close and [Private:x] = x seconds auto close. Something along those lines I think is a nice way to go about it.

    can u add the feaature that admins can look in all chests?
  17. Offline


    You need to set allow-admin-snoop to true in the config, for that.

    See above, and read the documentation.

    Capitalization matters. I'm considering how to catch bad names on line two, perhaps allow only the name of someone who is online?

    As for the doors bit, I'll consider your suggestion. :3

    Please please please please add permissions support, this is an awesome and easy to use plug-in, but I can't use it on my server because I need to permit certain groups to lock doors :(.

    Umm, this plugin already has permissions support. Read the advanced setup section.
  20. Offline


    Hello, I like the addon.
    Is there a way to only allow admins to make locks? I run permissions if that's of any importance.

    I got a problem
    I downloaded it but it does
    not show up in the console
    so it also does not work
    since i downloaded iconomy..
    it worked before but not now?

    We've done this simply because only two of our players are causing problems by stealing, so to save people having to list all the other people, we've told them to simply put [private] and [trusted] which is where everybody but the cheaters are in our permissions. The Admin alert was just irritating as it made it look like our admins were trying to be devious. Let me ask, why would an admin steal from somebody when they have the /give command? The only reason we check other peoples chests is to ensure they haven't stolen anything.

    I would LOVE the future feature of auto door closing
  29. Offline


    Some servers have a much more strict economy, no cheating of items with /give for anyone, whereas you still need admins who can break locks and etc. Aside from that, I believe in respecting the privacy of users, but I left this loophole in too. I suppose the intention is to have server ops consider if they really need to be able to use the snoop feature? That is my reasoning anyway. :3

    This seems to be a popular request, yes~ I'll see what I can do. :3

    Well, all I can suggest is the basics.. Make sure you unzipped Lockette.zip to get the jar.
    Make sure Lockette.jar is in the plugins folder, and that the plugins folder is in the same folder as your craftbukkit.jar.

    ok well i had this working fine on my older version But i updated to the newest bukkit and now when i place signs down its saying i dont have permission to do so? i updated my permissions but the permission txt doc is the same So i dont see how thats changed..

    1 thing i have noticed is a lot of changed in some things so is there something i need to do to get this to work? ty btw great mod ;)

    A simple switch on the floor will work But even then i only suggest that you have it on the inside because anyone can open doors using switches i think..

    Ps: Can people open doors using switches still? i dont know what version i was using but i remember having a switch door and people could open it even tho it was private.
