BlockLocker

Build Status Download at SpigotMC.org Latest release Commits since latest release

Lockette/Deadbolt clone that properly supports UUIDs (and the new doors), written from scratch.

Current features:

  • Locks chests, furnaces, doors and a few other containers using the familiar [Private] and [More Users] signs.
  • Signs placed against a container are automatically filled with [Private] and the name of the player.
  • Only the owner of a protection can destroy a protection.
  • Admins can still open protected doors and containers.
  • UUID support
    • UUIDs are saved to hidden hover text data on the sign, never visible for users.
    • Automatically looks up UUIDs for signs from Lockette and Deadbolt when they are read.
  • Fully configurable
    • All messages can be translated.
    • You can change which block types can be protected. Even more complex blocks like levers work correctly.
  • Group support: adding [MyGroup] to the sign will allow anyone with the permission node blocklocker.group.mygroup (grant the lowercase node) and anyone in a scoreboard team or in a faction of MassiveCraft Factions called MyGroup (case insensitive).
  • Correctly handles complex blocks:
    • Double door support: protecting one half also protects the other half, opening one half opens the other half.
    • Doors can be set to close automatically. BlockLocker does not just toggle the open state, it will actually close the door.
    • Double chest support: protecting one half also proects the other half.
    • Trapdoor support: the sign can be attached to either the "hinge"-block or the trapdoor itself.
    • Fence gate support: the sign can be attached to either the the fence gate block or the block below.
  • The owner of a protection can change the signs after creating them using the /blocklocker <line number> <name> command.
  • Auto-updater, so that you are notified when there is a new version available.

Compilation

BlockLocker uses Maven.

  • Install Maven 3
  • Download this repo and run the command mvn clean install

After running the command there will be a file blocklocker-XX.jar (where XX is a version number) in the target folder.

Hooking into BlockLocker

BlockLocker has two APIs for other plugins to use: version 1 and version 2. Right now, the only difference between them is that version 1 uses com.google.common.base.Optional while version 2 uses java.util.Optional. Version 1 was first included in BlockLocker 0.1, and the plan is to include it in all future versions of BlockLocker as long as the class com.google.common.base.Optional exists. Version 2 was realeased on November 17, 2019 with BlockLocker 1.7.

  • If your plugin supports Minecraft 1.14, chances are that people are still using BlockLocker 1.6, and you should use API version 1.
  • If your plugin supports Minecraft 1.13 or older, you'll have to use API version 1, as version 2 is not available for Minecraft 1.13.
  • If your plugin only supports Minecraft 1.15 and newer, then you can safely use API version 2.

Maven

Add the following repository to your pom.xml file:

<repository>
	<id>rutger-repo</id>
	<url>http://www.rutgerkok.nl/repo</url>
</repository>

Add the following file:

<dependency>
	<groupId>nl.rutgerkok</groupId>
	<artifactId>blocklocker</artifactId>
	<version>0.1</version> <!-- or 1.7, see below -->
	<scope>provided</scope>
</dependency>

If you want to use API version 1, use BlockLocker version 0.1, otherwise for API version 2 use BlockLocker 1.7. Other BlockLocker versions are not uploaded to this repository.

Check whether the plugin is enabled

boolean enabled = Bukkit.getPluginManager().getPlugin("BlockLocker") != null;

The BlockLockerAPI - version 1

The nice thing about API version 1 is that it works with all old BlockLocker versions, all the way back to version 0.1. Version 1 still uses the com.google.common.base.Optional class. Because Java 8 also includes an Optional class, it can be expected that Google's Optional will be removed at some point in the future. At this moment, this API will also dissappear. However, currently the Optional class is not deprecated by Google, so it will take at least two years for that class to get removed. So it's still safe to use this API.

Example usage:

Optional<OfflinePlayer> owner = BlockLockerAPI.getOwner(block);

In version 0.1 these methods were available in the BlockLockerAPI class:

getOwner(Block block)
getOwnerDisplayName(Block block)
isAllowed(Player player, Block block, boolean serverAdminsAlwaysAllowed)
isOwner(Player player, Block block)
isProtected(Block block)

You can view the complete class, along with documentation, here.

If you solely use these methods, your plugin will work with all versions of BlockLocker from the future and past.

The BlockLockerAPI - version 2

Use the class BlockLockerAPIv2 instead of BlockLockerAPI. There are no differences between version 2 and version 1 yet, except that the API now uses java.util.Optional instead of the older com.google.common.base.Optional.

More advanced functionality

I have kept the number of methods in BlockLockerAPI small, as each method will need to be around in all future versions of BlockLocker. If you need to do something more advanced, you need to venture outside the class. Keep in mind that your plugin might break in the future.

Here's an example for checking whether redstone is allowed in the protection:

private boolean isRedstoneAllowed(Block block) {
    BlockLockerPlugin plugin = BlockLockerAPI.getPlugin();
    Optional<Protection> protection = plugin.getProtectionFinder().findProtection(block);
    if (!protection.isPresent()) {
        // Not protected, so redstone is allowed to change things here
        return true;
    }
    Profile redstoneProfile = plugin.getProfileFactory().fromRedstone();
    // Will return true when [Redstone] or [Everyone] is on one of the signs
    return protection.get().isAllowed(redstoneProfile);
}

If you believe that a method should be added to BlockLockerAPI, please contact me. (See my Github profile for my e-mail.)

You can’t perform that action at this time.
