    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.

  2. Yep that would work. I'll code it tomorrow when I get up.

    Looks my temporary plugin is obsolete already! :p nice to see that Lockette will now account for this.

    Actually after sleeping on it my self. That is EXACTLY what you want to do. If you used an event handler, and say the server has like 100 hoppers no it in use, your looking at 100 event checks per tick? A bit too much overhead. This way you just block the player from placing a hopper altogether if they don't own the chest.

    I hope you are also making hoppers and trapped chest lockable. Since hoppers do have an inventory space in them as well.

    Too bad there isnt a way to lock storage minecarts..... I think that could be done with plugins that record blockbreak and blockplace events. I might have to drop a line with the LogBlock guys!
  5. You can lock any block by adding it's ID to the custom blocks entry in the Lockette config.

    The code is done and a new version is available, when the bukkit team finally approve the uploaded jar.
  6. Would this also prevent hopper minecarts to grab items from locked chests?

    -EDIT: I just checked with the latest version and it doesn't prevent Minecarts with Hoppers to grab items from locked chests. Is there a way to make sure that this doesn't happen?

    when i try to open i protected chest it says i do not have permission.
    I do have the "*" node though so it should work.
    what is the problem here?
  8. Offline


    Make sure your config is set to enable permissions.

    We're looking into this. Protecting locked chests from hoppercarts is a double-edged sword.
    You can block them pulling from locked chests but this means players will make their machines with unlocked chests.
    Or it could be left as it is now and players will need to protect their machines from outsiders, which isn't possible without another plugin like towny protecting the area.
    We might add an entry onto signs, [hoppercart] that would lock the chest but allow hoppercarts to pull from it.

    EDIT by Moderator: merged posts, please use the edit button instead of double posting.

  9. The [hoppercart] on a sign seems like the best solution to me. That way you can prevent people from using them to steal from you, but in case you want to use the hoppercart yourself you can do that. I would love to see this implemented.

    OK, call me stupid, but how do I place the sign on the chest...when I right-click on the chest it says "permission to lock container denied". I have lockette.admin.create.* and all other admin permissions. Do I also need lockette.user.create.* permision?

    nevermind...I answered my own question...you need user.create.*...so what does admin.create.* do then?

    i place a [private sign on my trapped chest but people can still open it]

    Hey umm, People can use hoppers to siphon items out of chests that are locked. Is that supposed to happen?

    Basically they just place a hopper under the chest and it pulls the items out

    Update your lockette to 1.7.11
  14. Offline


    Thanks lol... did not realise I did not have the lastest version.
  15. Offline


    1.7.11 has apparently re-introduced a bug that was solved before, [INFO] 77 (or as we once knew it..) [INFO] TRAPDOOR
  16. I see no spam. You must have the wrong version.
  17. Offline


    Is there anyway I can make it so you can lock trap chests? Like by changing something in the config file?
  18. Offline


    Yes, use the line of the config where you set up custom block ID's to be locked.
  19. Offline


    Thank you so much!

    There's another problem. When I lock a double trap chest from the side, other people can open it from one chest side but not the other.
  21. Offline


    It is possible to empty others' chestes by placing rail, and then a hopper minecart on the rail below the chest. Please fix this, and also, please make it possible to make hoppers private.

    - Thank you :D

    For some reason on my server it won't work on doors, i've checked the config and it lists doors as on, any special reason it might now work? Latest version 1.7.11.
  23. Offline


    I'm also waiting for this. :(
  24. Offline


    Can you add something into the configuration file that would say only allow X amount of items to be private signed for a pvp server so it allows them to have to choose to lock up a few things but not everything?
  25. Offline


    Not possible since lockette doesn't track the locked items as a whole. It protects each sign. Look into LWC, it can do this.
  26. Offline


    I prefer lockette over lwc just wanted this one feature LOL

    Question- I see that in Lockette 1.7.11 hoppers can't take stuff out of chests? This happens on my server running CraftBukkit 1.4.7-r1.0-75-g7f25632-b2718jnks (MC:1.5.1) (implementing API version 1.5.1 - r0.1-SNAPSHOT) which is what i thought to be the most stable .jar available on my BeastNode admin panel.

    Suggestion- And maybe I just can't figure this stuff out, but implement the teams in the new snapshot as groups/factions that one can put on a Lockette sign. If this exists, ignore me and point me in the right direction!

    Think you can make it not conflict with the InfiniteDispensers plugin?

    You might want to actually tell us the conflict if you want anything done about it.

    I opened a new ticket about a protection bypass :
    Screen : http://team-frenchie.com/web/up/minecraft/2013-04-28_18.02.10.png
    Lockette Version: 1.7.11
    Bukkit Version: (MC: 1.5.1) (Implementing API version 1.5.1-R0.3-SNAPSHOT
    Other Plugin Involved [if applicable]: none

    1- Place a protected chest with a sign
    2 - Place a rail below the chest
    3 - Place a Minecart+Hopper on the rail

    Résult : Minecarft-hopper get the protected chest content.

    Right sorry. So I would have both Lockette and InfiniteDispensers at the same time. To make an "infinite dispenser", you need to place the sign on a dispenser (crouch, then right click). You have to type in on the first line [Infinite]. (The [] are needed.) After I finish typing in the sign, it changes into:


    So yeah, it's pretty much impossible.
