CustomBlockData

CustomBlockData is a library for the Bukkit API that allows you to store ANY information inside blocks. It does so by providing the CustomBlockData class which implements the PersistentDataContainer interface.

It does not need any files or databases by saving the information inside the chunk's PersistentDataContainer, and the information is persistent even after server restarts.

CustomBlockData is compatible with all Bukkit versions from 1.16.3 onwards, including all forks. Older versions are not supported because Chunk only implements PersistentDataHolder since 1.16.3.

Advantages

It does not need any files or databases
When the chunk where the block is inside gets deleted, there will be no leftover information
You can store anything that can be stored inside a normal PersistantDataContainer (which means, basically, anything)
It can automatically keep track of block changes and automatically delete block data when a block gets broken, move data when a block gets moved, etc
- You can make specific blocks protected from this, or listen to the cancellable CustomBlockDataEvents
- (This is disabled by default for backwards compatibility - just call CustomBlockData#registerListener(Plugin) to enable it)

Shading and relocating

You must shade (and you should relocate) the CustomBlockData class. Just add this to the <configuration> section of your maven-shade-plugin declaration:

<relocations>
    <relocation>
        <pattern>com.jeff_media.customblockdata</pattern>
        <shadedPattern>YOUR.PACKAGE.customblockdata</shadedPattern>
    </relocation>
</relocations>

Gradle

Repository

repositories {
    maven {
      url = 'https://hub.jeff-media.com/nexus/repository/jeff-media-public/'
    }
}

Dependencies

dependencies {
    implementation 'com.jeff_media:CustomBlockData:2.2.0'
}

Shading & Relocating

You must shade (and you should relocate) the CustomBlockData class. You will need Shadow found on here. Add the following to your shadowJar section!

shadowJar {
    relocate 'com.jeff_media.customblockdata', 'your.package.customblockdata'
}

Usage

To get a block's PersistentDataContainer, all you have to do is create an instance of CustomBlockData providing the block and the instance of your main class:

PersistentDataContainer customBlockData = new CustomBlockData(block, plugin);

For more information about how to use it, just look at the API docs for the PersistentDataContainer or look at this tutorial.

Example plugin

Click here for an example plugin. It lets you left-click on a block to store your currently held ItemStack inside. Once the block is broken, it will drop the stored item.
