How to develop a Minecraft Plugin

Are you looking to create a Minecraft plugin, but don’t know where to start? Look no further! In this article, we will go over the steps to create your very own Minecraft plugin.

Before we begin, it’s important to note that creating a plugin for Minecraft requires some knowledge of programming. If you’re new to programming, it may be helpful to familiarize yourself with a programming language such as Java before attempting to create a plugin.

With that being said, let’s get started!

Coding Minecraft Plugins

Prequisites

Before we get started, there are a few things you will need in order to develop a Minecraft plugin:

  • A Minecraft server: You will need to have a Minecraft server set up in order to test your plugin. Fortunately, you are reading the blog of a game server provider right now. Create your own server in a snap.
  • Java: Minecraft plugins are written in Java, so you will need to have the Java Development Kit (JDK) installed on your computer. You can download the JDK from the Oracle website: https://www.oracle.com/java/technologies/javase-downloads.html
  • An integrated development environment (IDE): An IDE is a piece of software that provides a convenient interface for writing, debugging, and testing code. There are many different IDEs available, but some popular options for Java development include Eclipse and IntelliJ IDEA. You can choose whichever one you are most comfortable with.

Setting up your project

  1. First, you will need to create a new project in your IDE. In Eclipse, you can do this by going to File > New > Java Project. In IntelliJ IDEA, you can go to File > New > Project.
  2. Next, you will need to add the Spigot API (Application Programming Interface) as a dependency to your project. The Spigot API is a set of Java libraries that provide access to the internals of the Spigot server and allow you to create plugins. You can download the latest version of the Spigot API from the Spigot website: https://www.spigotmc.org/wiki/buildtools/. Once you have downloaded the API, you will need to add it to your project’s build path. In Eclipse, you can do this by right-clicking on your project in the Package Explorer and selecting “Build Path > Add External Archives”. In IntelliJ IDEA, you can go to File > Project Structure > Libraries and click the “+” button to add the API as a library.
  3. You will also need to create a plugin.yml file, which is a configuration file that tells Spigot how to load and manage your plugin. This file should be placed in the root directory of your project. You can find more information about the plugin.yml file and the different options available here: https://www.spigotmc.org/wiki/creating-a-plugin-yml-file/.

Writing your Plugin

  1. The first thing you will need to do is create a main class for your plugin. This class should extend the Java Plugin class from the Spigot API and override the onEnable() and onDisable() methods. The onEnable() method is called when your plugin is loaded by the server, and the onDisable() method is called when your plugin is unloaded. These methods are a good place to put any code that needs to be executed when your plugin is enabled or disabled.
  2. Next, you will want to start thinking about what features you want your plugin to have. Do you want to add a new command for players to use? Do you want to create a new type of block or item? Do you want to change the way the game works in some way? Once you have a clear idea of what you want your plugin to do, you can start implementing those features.
  3. To create a new command, you will need to create a class that implements the CommandExecutor interface from the Spigot API. This interface has a single method, onCommand(), which is called when a player uses the command. You will need to override this method and provide your own implementation. You can find more information about creating commands in the Spigot documentation: https://www.spigotmc.org/wiki/creating-a-command/.
  4. To create a new block or item, you will need to use the Bukkit API (another library provided by Spigot). You can find more information about creating custom blocks and items in the Bukkit documentation: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Material.html.
  5. To change the way the game works, you will need to use the Bukkit API to listen for events and react to them. For example, if you want to change the way players are damaged, you can listen for the EntityDamageEvent and cancel it or modify the damage value. You can find more information about listening for events and reacting to them in the Bukkit documentation: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/Event.html.

Testing and deploying your plugin

  1. Once you have finished writing your plugin, you will need to test it to make sure it is working as expected. You can do this by downloading your plugin’s jar file (which you can build by right-clicking on your project in the IDE and selecting “Export > JAR file”). This file can then be uploaded to your Pockethost Minecraft server.. Then, start the server and check the console for any errors or messages. If your plugin is working correctly, you should see a message saying that it has been enabled.
  2. If your plugin is working as expected, you can share it with other players by uploading it to a website like SpigotMC or BukkitDev. Players can then download and install your plugin on their own servers.

Conclusion

Developing a Minecraft plugin can be a fun and rewarding experience, and it’s a great way to learn about programming and game development. With the help of the Spigot and Bukkit APIs, you can add all sorts of new features and functionality to your Minecraft server. Whether you want to create a simple command or a complex minigame, the possibilities are endless.
