BlockLocker 1.5.0

Protect chests, doors, etc. using signs. UUID compatible.

    Source Code:

    This plugin allows you to protect chests, doors, furnaces, dispensers, droppers, hoppers and many other blocks simply using signs. Once a sign is attached, only people listed on the sign can access the container. It uses no databases, all information is stored on sign attached to the protected block. So if you use WorldEdit to move a chest, the chest will still be protected.

    The plugin can be used as a replacement for LockettePro. Existing protections will look a bit funny at first (the UUID on the sign is not hidden, as BlockLocker does not include a protocol hack), but once you interact with the protection it will be updated to look normal again. This is because BlockLocker stores the UUID on a "hover text", which is hidden automatically by the Minecraft client.

    The plugin can also be used as a replacement for the classic plugins Deadbolt and Lockette: BlockLocker will automatically lookup and store the UUID of players once a player interacts with a protection. (Lockette does not store UUIDs anywhere, so they're gone when you restart the server. Deadbolt has no UUID support at all.) This online UUID lookup will not block the server: so you won't have lag if Mojang.com is slow to respond.

    Features

    [​IMG]

    • Protect chest, doors, etc. simply by attaching a sign.
    • Doesn't need a database, the plugin just looks for attached signs.
    • Allow other players to access your protection.
    • Allow groups to access your protection.
      • Groups are defined using permission nodes, scoreboard teams, Towny towns, Towny nations or MassiveCraft Factions
    • UUID support
      • Players can change their names without losing access to their protected blocks.
      • Stores UUIDs on signs in a hidden text component, so UUIDs are saved between server restarts.
    • Supports double doors and double chests (double trapped chests too): you only need one sign to protect both blocks.
    • Shows a message to players placing a chest, so that they know chests can be protected.
    • Automatically closes doors when a [Timer:X] tag is added, or when a default door close time has been specified in the config file.
    • Redstone support
      • Redstone contraptions cannot open protected doors, unless a [Redstone] tag is added.
      • Hoppers (minecart hoppers too!) cannot take or put items, unless a [Redstone] tag is added.
    • Auto-updater
      • Server owners get notified when there is a BlockLocker update available.
      • The auto-updater works asynchronously, it will never block the server.
      • The auto-updater used to be able to download and install JAR files from spigotmc.org (it is restricted to spigotmc.org only). The code for this is still in the plugin. However, the plugin isn't able to contact spigotmc.org anymore, probably because of a DDOS protection measure. As a result, the auto-updater can only notify you of updates, but you have to download them yourself.
      • The auto-updater can of course be toggled off.
    • Configuration
      • Add extra blocks, for example TNT, levers or note blocks.
      • You can set that "attachable" blocks like levers can be protected by attaching a sign on the block the lever is attached on (no need to put signs on the lever itself!)
      • All messages can be translated.
      • Reload config files while the server is running using /blocklocker reload

    Usage

    [​IMG]

    Placing signs
    For containers (chests, furnaces, dispensers, etc.) it's easy: just place a sign against the block. BlockLocker will automatically add [Private] to the first line and your name to the second.

    You can also place a sign while sneaking, this allows you to add some text to the third and fourth lines. You then need to write[Private] yourself on the first line. You can leave the second line empty, your name will automatically be placed here.

    For doors, place a sign with [Private] on the first line against the block above the door. Placing a sign on the block below the door or even on the door itself works too, but looks less nice.

    Trapdoors can be protected by placing a sign with [Private] on the first line against the block the trapdoor is attached to.

    Editing signs
    Right-click the sign and type /blocklocker <line number> <text> to replace the text on the given line. You can shorten this to /bl <line number> <text>.

    Adding people to the sign
    On the third and fourth row of the sign with [Private] you can add the names of up to two friends who may also access the chest. Want to add more people? Place a second sign against the chest. BlockLocker will add [More Users] to the first line and [Everyone] to the second line. If you want to change this, right-click the sign to edit it.

    If the name of the person you're adding doesn't fit on the sign, just type as many characters as possible. If the person you're adding is currently online, BlockLocker will be able to complete the name.

    If no Minecraft account exists with the name, a ~ is added before the name. However, the ~ is not added for things that don't look like an username, so --text-- won't be changed to ~--text--. This should still give you plenty of options to decorate the sign, while it will still be obvious when name is not a valid Minecraft name.

    Special tags

    [​IMG]

    The tag [Everyone] grants everyone access to the protection. The tag [Redstone] grants hoppers access to the container, and allows redstone signal to open doors.

    [​IMG]

    There's also a [Timer:X] tag, where X is a number from 0 to 9. Doors (trapdoors too) will close automatically after the specified amount of seconds. Use 0 to never close the door automatically. The timer tag overrides the default close timer setting the config.yml.

    You can also add [MyGroup], which will grant all members of the group MyGroup access to the chest. See "Group support" below for what groups are supported.

    Finally, you can also add +MyGroup+, which grants mayors and assistants of a Towny town or nation access.

    Setup

    Permissions
    There's a very simple permission structure:

    • blocklocker.protect - create new protections
    • blocklocker.bypass - bypass all protections, edit all protections
    • blocklocker.reload - use /bl reload to reload the configuration files
    • blocklocker.group.groupName - adds you to the group with the name groupName, so that you have access to protections with a [groupName] tag on it.
    • blocklocker.wilderness - place chests outside Towny towns. Granted by default, so use your permissions plugin to negate this permissions if you don't want people to place chests in the wilderness. Has no effect if Towny is not installed.

    Commands
    • /blocklocker <line number> <text> - places the specified text on the last sign you selected (right-clicked). You can only select signs on your own protections, unless you have the permission node blocklocker.bypass.
    • /blocklocker reload - reloads configuration files. Requires the permission node blocklocker.reload

    Configuration
    You can change what block types can be protected, you can set a default close timer for doors and you can set whether one sign protects a whole row of containers, or only the current container.

    The file plugins/BlockLocker/config.yml contains explanations of all settings, I won't repeat them here. Just open the file!

    There's also a translation file, you can edit all user-visible text here, as well as changing the [Private], [More Users], etc. tags to something else.

    When you have made a change, run the command /bl reload for your settings to take effect. You can of course also restart the server.

    Group support

    [​IMG]

    When placing [MyGroup] on a sign, every member of MyGroup will have access to the protection. The plugin considers the following persons to be a member of the group MyGroup:

    • People with the permission node blocklocker.group.mygroup. The permission node is always blocklocker.group. with the lowercase group name appended to it.
    • People in the scoreboard team MyGroup (case insensitive). You can modify scoreboard teams using the (vanilla) command /scoreboard.
    • When MassiveCraft Factions is installed: people in the faction called MyGroup (case insensitive).
    • When Towny is installed: people in a town or nation called MyGroup (case insensitive).

    When placing +MyGroup+ on the sign, only mayors and assitants of Towny towns and nations called MyGroup will have access.

    Other group systems are currently not supported. If you want support for another plugin, just ask me.

    Automatic updater
    For a plugin designed to protect you, it is important that any security fixes can be pushed out quickly. That's why the plugin includes an auto-updater as of version 1.0.

    The updater is restricted to downloading files only from my website. It will only download files marked as compatible with your Minecraft version. It will also only install files marked as suitable for automatic updating.

    The updater works asynchronously: it will never pause your server while it's downloading something. Update files are placed in plugins/update so that the file will automatically replace the old file on the next server startup.

    If you want to disable the updater, or if you want to restrict it to only notify for updates (but never download them) you must edit the plugins/BlockLocker/config.yml file. Set the updater setting in the file to DISABLED or JUST_NOTIFY. If you don't see the update setting in the file it is because you have a pre-1.0 config file. Simply add updater: DISABLED or updater: JUST_NOTIFY to a new line and you'll be fine.

    UUID support
    BlockLocker has been built with UUID support in mind. Minecraft 1.8 allows signs to use chat components. BlockLocker adds a hidden chat component with UUID information.

    When your server is running in offline mode, not behind a BungeeCord proxy, the plugin won't use UUIDs and will continue to use names.

    When UUIDs are used, the plugin accesses api.mojang.com every now and then to look up UUIDs of offline players added to a sign.

    Bugs

    If you have found a bug, please report it! You can report it here in in the forum thread, or on Github. Please provide instructions for me how I can reproduce the bug.

    Any questions?

    Can you add this feature?
    Just ask in the forum thread. :)

    I won't add features that require a database. Example: limiting the amount of protections you can create, this requires setting up a database that counts the amount of protections of each player.

    How do I change the color scheme of messages, [Private] and [More Users]?
    Open plugins/BlockLocker/translations-en.yml (if you're using another language, open up that file instead) and add/remove color codes.

    Are old Minecraft versions supported?

    Nope. For older Minecraft versions, please download an older release of BlockLocker.

    Minecraft 1.13: use BlockLocker 1.5.0
    Minecraft 1.12: use BlockLocker 1.3.4
    Minecraft 1.9 to 1.11: use BlockLocker 1.3.3
    Minecraft 1.8: use BlockLocker 1.2.0
    Even older: BlockLocker didn't exist yet

    Hoppers cannot put items into/take items from chests. How can I fix this?
    Add a line with the text [Redstone] or [Everyone] to the sign.

    What are the differences between this plugin and LockettePro?
    This plugin uses no code from LockettePro. It was written from scratch. I have listed the major differences here, but there are many more smaller differences.

    Both LockettePro and BlockLocker store the UUID of players on the sign, which is a good thing: the UUID data cannot get lost, even when you are using WorldEdit to move a sign. LockettePro stores UUIDs of players in the sign text as Name#UUID, so for example Notch#069a79f4-44e9-4726-a5be-fca90e38aaf5. It uses a protocol hack to hide the UUID. For this, the plugin requires ProtocolLib. BlockLocker stores the UUID in a hover text on the sign. Unlike for chat messages, signs never display their hover text, even if your mouse cursor is on the sign. Therefore, no protocol hack was needed to hide the UUID of players: Minecraft already hides this text.

    LockettePro supports as many alternative texts for the [Private], [More Users] and [Timer:X] tags as you want, but BlockLocker currently supports only one text. While this is less confusing for players (they would wonder what the difference between for example a [Private], [No Entry] and a [No Access] sign is), I can see how it causes problems if you currently already have a server with multiple alternatives for [Private]).

    LockettePro currently supports SimpleClans and Vault groups while BlockLocker doesn't. However, BlockLocker supports groups based on permission nodes: if you for example grant someone the permission node blocklocker.group.myexample, then that player will belong to the group MyExample (case insensitive). Groups from Towny and MassiveCraft Factions are supported in both plugins.

    LockettePro has only rudimentary redstone support. You have to add [Everyone] to your door for redstone to work. In BlockLocker [Everyone] still works, but you can also add a [Redstone] tag instead.

    Hoppers are not well supported in LockettePro: either they never take items from protected containers, or always, depending on a configuration setting. BlockLocker allows you to add a [Redstone] tag to allow hoppers. When no [Redstone] (or [Everyone]) tag is added, hoppers won't be able to place or take items from the container.

    What are the differences between this plugin and the classic Lockette?
    This plugin uses no code from Lockette. It was written from scratch. I have listed the major differences here, but there are many more smaller differences.

    Lockette has no real UUID support: it just looks up your old names. (UUIDs are cached as Bukkit metadata, but not saved, so they are lost when the server restarts.) BlockLocker uses hidden text components, which means that the data is stored safely inside the chunk and that external editors like MCEdit won't delete the UUID data.

    Lockette has only rudimentary redstone support. You have to add [Everyone] to your door for redstone to work. In BlockLocker [Everyone] still works, but you can also add a [Redstone] tag instead.

    Hoppers are not well supported in Lockette: either they never take items from protected containers, or always, depending on a configuration setting. BlockLocker allows you to add a [Redstone] tag to allow hoppers. When no [Redstone] (or [Everyone]) tag is added, hoppers won't be able to place or take items from the container.

    Placing signs works a little different. In both plugins you can attach a sign to a container simply by right-clicking the container with a sign in your hand. The sign will be filled with [Private] on the first line and your name on the second line. In Lockette you can also place a sign next to a container. You have to manually type [Private] on the first line. Lockette will then move the sign so that it is attached to the chest. I find this behaviour not very useful, so it is not included in BlockLocker. For those cases where you want to add something to the third or fourth line of the sign, you can either edit the sign after placing it, or you can place the sign while sneaking, allowing you manually edit the sign.

    Lockette currently has hooks for many plugins (McMMO, SimpleClans, etc.) for group support, BlockLocker currently only has hooks for vanilla scoreboard teams, permission nodes, Towny towns, Towny nations and MassiveCraft Factions.

    I have another question.
    Please ask! The best place is here in the forum thread. You can also send me a PM, but keep in mind that others won't be able to benefit from any solution you found.

      Author's Response
      For doors, there is no automatic sign placement. So place a sign with [Private] on the first line next to the door (or above or below it, or even on the door) to lock it.

      Also, please use the discussion tab for questions, this is the review area. :)

    Version: 1.3.4
    Works great on our server.

    One suggestion:
    Instead of signs use a command instead like /lock then do /trust and /untrust to add people to open the chest.
    1. rutgerkok
      Author's Response
      Thanks!

      The problem with adding commands is that I need some place to store who's the owner of the chest. Now that information is stored on the sign, which has the advantage that no external database is needed. This means that you can freely move chests using WorldEdit (or McEdit) without the chest getting unlocked.

      If you're looking for a plugin that does use commands (and therefore an external database), see LWC. I'm not going to rework this plugin to use a database, that would require too much effort. Besides, supporting both signs and databases would make the plugin too complex.

    I use the plugin on my 1.10.2 server and it works like a charm. I'm not sure which version I use for that server so whatever it says I'm reviewing is not accurate. Planning to update my server to 1.12 which is why I'm downloading the latest version now.
    Definitely recommend this plugin to anyone that doesn't allow raiding on their servers! :)
