The HuskTowns API provides methods for interfacing and editing towns, claims and users, alongside a selection of API events for listening to when players perform certain town actions.

Compatibility

The HuskTowns API shares version numbering with the plugin itself for consistency and convenience. Please note minor and patch plugin releases may make API additions and deprecations, but will not introduce breaking changes without notice.

Platforms

Note:

For versions older than v3.0, the HuskTowns API was only distributed for the Bukkit platform (as net.william278:husktowns)

The HuskTowns API is available for the following platforms:

• bukkit - Bukkit, Spigot, Paper, etc. Provides Bukkit API event listeners and adapters to org.bukkit objects.
• common - Common API for all platforms.

API Introduction

1.1 Setup with Maven

<repositories>
    <repository>
        <id>william278.net</id>
        <url>https://repo.william278.net/releases</url>
    </repository>
</repositories>

<dependency>
    <groupId>net.william278.husktowns</groupId>
    <artifactId>husktowns-PLATFORM</artifactId>
    <version>VERSION</version>
    <scope>provided</scope>
</dependency>

1.2 Setup with Gradle

allprojects {
    repositories {
        maven { url 'https://repo.william278.net/releases' }
    }
}

dependencies {
    compileOnly 'net.william278.husktowns:husktowns-PLATFORM:VERSION'
}

2. Adding HuskTowns as a dependency

Add HuskTowns to your softdepend (if you want to optionally use HuskTowns) or depend (if your plugin relies on HuskTowns) section in plugin.yml of your project.

name: MyPlugin
version: 1.0
main: net.william278.myplugin.MyPlugin
author: William278
description: 'A plugin that hooks with the HuskTowns API!'
softdepend: # Or, use 'depend' here
  - HuskTowns

3. Creating a class to interface with the API

• Unless your plugin completely relies on HuskTowns, you shouldn't put HuskTowns API calls into your main class, otherwise if HuskTowns is not installed you'll encounter ClassNotFoundExceptions

public class HuskTownsAPIHook {

    public HuskTownsAPIHook() {
        // Ready to do stuff with the API
    }

}

4. Checking if HuskTowns is present and creating the hook

• Check to make sure the HuskTowns plugin is present before instantiating the API hook class

public class MyPlugin extends JavaPlugin {

    public HuskTownsAPIHook huskTownsAPIHook;

    @Override
    public void onEnable() {
        if (Bukkit.getPluginManager().getPlugin("HuskTowns") != null) {
            this.huskTownsAPIHook = new HuskTownsAPIHook();
        }
    }
}

5. Getting an instance of the API

• You can now get the API instance by calling HuskTownsAPI#getInstance()
• If targeting the Bukkit platform, you can also use BukkitHuskTownsAPI#getBukkitInstance() to get the Bukkit-extended API instance (recommended)

import net.william278.husktowns.api.HuskTownsAPI;

public class HuskTownsAPIHook {

    private final HuskTownsAPI huskTownsAPI;

    public HuskTownsAPIHook() {
        this.huskTownsAPI = HuskTownsAPI.getInstance();
    }

}

6. CompletableFuture and Optional basics

• HuskTowns API methods often deal with CompletableFutures and Optionals.
• A CompletableFuture is an asynchronous callback mechanism. The method will be processed asynchronously and the data returned when it has been retrieved. Then, use CompletableFuture#thenAccept(data -> {}) to do what you want to do with the data you requested after it has asynchronously been retrieved, to prevent lag.
• An Optional is a null-safe representation of data, or no data. You can check if the Optional is empty via Optional#isEmpty() (which will be returned by the API if no data could be found for the call you made). If the optional does contain data, you can get it via `Optional#get().

Warning:

You should never call #join() on futures returned from the HuskTownsAPI as futures are processed on server asynchronous tasks, which could lead to thread deadlock and crash your server if you attempt to lock the main thread to process them.
