Curious about how to customise Minecraft and learn real coding? This guide to Minecraft modding with Java is the perfect start for kids and parents! We’ll walk you through making your very own Minecraft mod, step by step, in a fun and simple way. Let’s unleash creativity, boost digital skills, and have safe, hands-on coding adventures together!


Step-by-Step Guide to Minecraft Modding with Java

Embarking on your Minecraft modding journey is easier than you think! This section will show you how to set up everything safely, understand Java basics, and create your first simple mod. If you’re wondering “how do I add mods to Minecraft Java?” – you’ll find out here in a way that’s perfect for beginners and young coders.


  1. Install Java Development Kit (JDK): Download and install JDK 17 to allow Minecraft modding in the Java Edition. Always download from official sources and follow computer safety tips with your child.

  2. Set Up an IDE (Eclipse): Eclipse is a free text editor and coding environment for Java. Install it to write and manage your modding code easily.

  3. Install Minecraft Forge: Forge is a modding platform for Minecraft Java Edition. Download the version matching your Minecraft (like 1.18) and extract it into a dedicated project folder.

  4. Install a Simple Image Editor: Pinta is a kid-friendly drawing tool for making or editing custom textures (like sword graphics) for your mod.

  5. Create Your Modding Project: Open Eclipse, set a workspace folder, and import your Forge project using Gradle. This gives you all the files needed to start coding your first mod!

  6. Write & Edit Java Code: Open the ExampleMod.java file, personalise your mod name, and start small—like creating a new sword. This is where code learning begins, and parents can guide kids with simple changes!

  7. Test and Customise: Run your mod inside the Minecraft Forge environment. Add your new item, check how it behaves, and use Pinta to create unique textures for your tools or weapons!

  8. Build and Add to Minecraft: When ready, compile your project into a .jar file, place it in the Minecraft 'mods' folder, and launch the game with Forge. Watch your mod come to life!


Throughout each step, ensure online safety by helping your child download files only from trusted websites, never sharing personal info, and always coding together. With Java modding, kids learn problem-solving, logical thinking, and teamwork in a safe gaming space.
