# Building Your First Hytale Plugin from Zero to Production
⚡ STATUS: LIVE (UPDATED 2025)
🔧 PLATFORM: HytaleSDK
Prerequisites
Before you begin, ensure you have the following:
* Java Development Kit (JDK) 8 or higher installed on your computer
* A code editor or IDE (such as Eclipse or IntelliJ IDEA)
* The Hytale SDK and Hytale server installed on your computer
* Basic knowledge of Java programming and YAML configuration files
Introduction
In this tutorial, we will guide you through the process of building your first Hytale plugin from scratch. By the end of this tutorial, you will have a fully functional plugin that can be used in your Hytale server.
Step-by-Step Guide
1. Create a new Java project: Create a new Java project in your preferred IDE or code editor. Name the project (e.g., "MyFirstPlugin") and ensure it is using the correct JDK version.
2. Add the Hytale SDK dependency: Add the Hytale SDK dependency to your project's `pom.xml` file (if using Maven) or `build.gradle` file (if using Gradle). This will allow you to use the Hytale API in your plugin.
// Maven
// Gradle
dependencies {
implementation 'com.hytale:hytale-sdk:1.0'
}
3. Create the plugin class: Create a new Java class that will serve as the main plugin class. This class must extend the `Plugin` class from the Hytale SDK.
package com.example.myfirstplugin;
import com.hytale.plugins.Plugin;
public class MyFirstPlugin extends Plugin {
@Override
public void onEnable() {
// Code to be executed when the plugin is enabled
}
@Override
public void onDisable() {
// Code to be executed when the plugin is disabled
}
}
4. Configure the plugin: Create a `plugin.yml` file in the root of your project. This file contains configuration data for your plugin, such as its name, version, and author.
name: MyFirstPlugin
version: 1.0
author: YourName
main: com.example.myfirstplugin.MyFirstPlugin
5. Add plugin functionality: Add code to the `onEnable()` and `onDisable()` methods to perform actions when the plugin is enabled or disabled. For example, you can add a command to the plugin that sends a message to the server when executed.
@Override
public void onEnable() {
getCommand("hello").setExecutor(new HelloCommand());
}
public class HelloCommand implements CommandExecutor {
@Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
sender.sendMessage("Hello, world!");
return true;
}
}
6. Compile and package the plugin: Compile the plugin code and package it into a JAR file. This can be done using the `mvn package` command (if using Maven) or the `gradle build` command (if using Gradle).
7. Install the plugin: Copy the JAR file to the `plugins` directory of your Hytale server. Restart the server to enable the plugin.
8. Test the plugin: Test the plugin by executing the command you added in step 5. If the plugin is working correctly, you should see the message "Hello, world!" sent to the server.
Common Mistakes
* Forgetting to add the Hytale SDK dependency to the project
* Not extending the `Plugin` class in the main plugin class
* Not configuring the `plugin.yml` file correctly
* Not packaging the plugin into a JAR file correctly
Troubleshooting
* If the plugin is not enabling, check the server logs for errors
* If the plugin is not executing commands, check the command registration code
* If the plugin is not sending messages, check the message sending code
Next Steps
Now that you have created your first Hytale plugin, you can start exploring more advanced features of the Hytale SDK. Some suggestions for next steps include:
* Adding more commands to the plugin
* Creating custom events and listeners
* Using the Hytale API to interact with the game world
* Creating a plugin configuration file to store user settings
* Publishing the plugin on the Hytale community forums or other plugin repositories.
