Block Metadata

A library for Minecraft plugins, allowing for efficient storage of persistent block metadata. Store metadata for a very large number of blocks without performance overhead. Fully asynchronous and multi-threaded for maximum performance.

Getting started

To get started, add the Block Metadata library to your plugin. You can do this easily using either Maven or Gradle.

Adding Block Metadata by Gradle

Modify your build.gradle file to include the following:

repositories {
	maven { url 'https://jitpack.io' }
}

dependencies {
	implementation 'com.github.itsMatoosh:block-metadata:1.6.1'
}

Adding Block Metadata by Maven

Modify your pom.xml file to include the following:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

<dependency>
    <groupId>com.github.itsMatoosh</groupId>
    <artifactId>block-metadata</artifactId>
    <version>1.6.1</version>
</dependency>

Usage

In order to use Block Metadata, instantiate a BlockMetadataStorage for each type of metadata you would like to store.

Here, we will instantiate a BlockMetadataStorage that can be used to store String metadata for each block.

public class YourPlugin extends JavaPlugin {

    private BlockMetadataStorage<String> metadataStorage;

    @Override
    public void onEnable() {
        // get the directory to save the metadata data in
        Path dataDir = this.getDataDirectory().toPath().resolve("data");
    
        // create the metadata store
        metadataStorage = new BlockMetadataStorage<>(this, dataDir)       
    }
}

Setting block metadata

We can use the instantiated BlockMetadataStorage to store metadata on blocks.

Block block = ...
BlockMetadataStorage<String> metadataStorage = ...
metadataStorage.setMetadata(block, "abcd");

Fetching block metadata

We can use the instantiated BlockMetadataStorage to fetch metadata from blocks.

Block block = ...
BlockMetadataStorage<String> metadataStorage = ...
metadataStorage.getMetadata(block).thenAccept(data -> {
    // do something with the metadata
    ...
})

Clearing block metadata

We can use the instantiated BlockMetadataStorage to clear metadata from blocks.

Block block = ...
BlockMetadataStorage<String> metadataStorage = ...
metadataStorage.removeMetadata(block).thenAccept(data -> {
    // do something with the removed metadata
    ...    
});
