Beginner’s Guide to Creating a Minecraft Plugin

Introduction

Developing a Minecraft plugin can be an exciting way to add custom features to the game. This guide is designed for complete beginners and will walk you through setting up your development environment with IntelliJ IDEA and creating a basic Minecraft plugin.

Step 1: Download and Install IntelliJ IDEA

IntelliJ IDEA is an Integrated Development Environment (IDE) used for developing software, including Minecraft plugins. Follow these steps to download and install it:

  1. Visit the IntelliJ IDEA Download Page

    • Go to IntelliJ IDEA Download using your web browser.
    • This page lists two versions: Community and Ultimate. The Community version is free and sufficient for our purposes. (scroll to the bottom of the page to find the community edition which is the free version)
  2. Download the Community Edition

    • Click on the ‘Download’ button under the Community section.
  3. Install IntelliJ IDEA

    • Once the download is complete, open the installer.
    • Follow the installation instructions. Default settings are usually fine for beginners.

Step 2: Install the ‘Minecraft Development’ Plugin

The ‘Minecraft Development’ plugin in IntelliJ IDEA adds specialized tools for creating Minecraft plugins.

  1. Open IntelliJ IDEA

    • Launch the program from your desktop or start menu.
  2. Access Plugins Settings

    • On the welcome screen, click on Plugins (bottom-left).
    • If you’ve opened a project, click File in the menu bar, then Settings (or Preferences on macOS), and select Plugins from the left panel.
  3. Install the Plugin

    • In the Plugins section, go to the ‘Marketplace’ tab.
    • Type “Minecraft Development” into the search bar and press Enter.
    • Find the ‘Minecraft Development’ plugin in the search results and click Install.
    • After installation, restart IntelliJ IDEA if prompted.

Step 3: Create Your First Plugin Project

Now, you’re ready to start your first Minecraft plugin project.

  1. Start a New Project

    • On the IntelliJ IDEA welcome screen, click New Project.
    • Select Minecraft from the options on the left. If you don’t see this, ensure the ‘Minecraft Development’ plugin is properly installed.
  2. Configure Your Project

    • Choose Minecraft Plugin as the project type.
    • Fill in the Project Name and select a Project Location to save your files.
    • Select the Minecraft Version you’re targeting with your plugin.
    • Click Next and then Finish.
  3. Familiarize Yourself with the Project Structure

    • IntelliJ IDEA opens your new project. You’ll see folders and files in the Project view, which is essential for organizing your code.
    • The src folder is where you’ll write your Java code.
  4. Write Basic Plugin Code

    • In the src folder, IntelliJ IDEA creates a main class file with your project’s name. This file is the entry point of your plugin.
    • Modify this file to add simple functionality, like printing a message when the plugin starts.
  5. Testing Your Plugin

    • To test your plugin, you’ll need a Minecraft server. You can set up a local server or use a testing server that supports plugins.
    • Compile your plugin into a .jar file and place it in the plugins directory of your server.
    • Start your server and test the functionality of your plugin.

Conclusion

Congratulations! You’ve just taken the first steps into Minecraft plugin development. Remember, this is just the beginning. There’s much more to learn about plugin development, including handling events, creating commands, and interacting with the Minecraft world.
