Versioning

We use Semantic Versioning 2.0.0 to manage our releases.

Features

  • Easy to use
  • Include reactor core
  • ServerThread sync
  • Chain-based wrappers for sync part of code with ServerThread

Important

Download

Download from our repository or depend via Gradle:

repositories {
    maven("https://repo.animecraft.fun/repository/maven-snapshots/")
}
dependencies {
    implementation("dev.ckateptb.minecraft:Atom:<version>")
}

How To

  • Import the dependency as shown above
  • Add Atom as a dependency to your plugin.yml
name: ...
version: ...
main: ...
depend: [ Atom ]
authors: ...
description: ...
  • Run tasks in async thread
public class PluginExample extends JavaPlugin {
    public PluginExample() {
        Schedulers.boundedElastic().schedule(() -> {
            // The common boundedElastic instance, a Scheduler that dynamically
            // creates a bounded number of ExecutorService-based
            // Workers, reusing them once the Workers have been
            // shut down. The underlying daemon threads can be
            // evicted if idle for more than 60 seconds.
        });
        Schedulers.single().schedule(() -> {
            // The common single instance, a Scheduler that hosts a 
            // single-threaded ExecutorService-based worker.
            // Only one instance of this common scheduler will be created
            // on the first call and is cached. The same instance is returned
            // on subsequent calls until it is disposed.
        });
        Schedulers.immediate().schedule(() -> {
            // Executes tasks immediately instead of scheduling them.
        });
        Schedulers.parallel().schedule(() -> {
            // The common parallel instance, a Scheduler that hosts
            // a fixed pool of single-threaded ExecutorService-based
            // workers and is suited for parallel work.
            // Only one instance of this common scheduler will be created
            // on the first call and is cached. The same instance is returned
            // on subsequent calls until it is disposed.
        });
        Atom.syncScheduler().schedule(() -> {
            // The bukkit tick thread instance, a Scheduler that 
            // can be used for sync sth with main server thread.
        });
    }

  • Work with block
public class ThreadSafeBlockExample {
    public void example() {
        // Pseudo async block placement example with queue
        Schedulers.boundedElastic().schedule(() -> // Async thread 
                Flux.fromIterable(blocks) // Flux from blocks iterator
                        // Declare queue 1 bpms = 50 bpt = 1000 bps
                        .concatMap(block -> Mono.just(block).delayElement(Duration.of(1, ChronoUnit.MILLIS)))
                        .publishOn(Atom.syncScheduler()) // Switch to main-thread
                        .subscribe(block -> block.setType(Material.AIR, false))); // do sth
    }
}
