A Complete Forge Modding Training for Minecraft 1.20.X

Welcome to Forge Mastery Week One! This will be a breakthrough week because we are going to be making our first fully customized mod from scratch. There is a lot of exciting stuff and I can’t wait to show it all to you!

Note: Please complete the “Initial Setup” week in Java Masterclass before continuing which we gifted you for free. 

Here’s what we are going to cover:

• Assembling your mod: How to download the Forge or NeoForge modding SDK.
• Configuring Gradle: Using Gradle in IntelliJ to build our mod.
• Parchment mappings: Switching from Forge to Parchment mappings for better deobfuscation of parameter names and fields.
• Running client: How to run Minecraft using Gradle with one button click from your IntelliJ to debug your mod and save time.

Since a lot of you are using Windows and it’s one of the least optimized operating systems, I’ll be showing you how to make sure your computer is running at its peak to reduce waiting for compilation times, improve FPS and overall modding experience.

If you save 1 minute waiting for the mod to load and you are repeating this task 10x per day, 5 days a week, that is 50 minutes a week, which is 200 minutes per month. That is 3h20m you could be spending with your loved ones and doing stuff you love instead of staring at the fucking loading screen.

Here’s what we are going to cover:

• IntelliJ optimization: Reducing background tasks in IntelliJ by removing unneeded plugins.
• Windows Software optimization: A high level overview of what I do to keep my Windows computers in high performance state at all times.
• Services trimming: Disabling unnecessary Windows services to reduce background noise.
• (Advanced) Custom Windows: I’ll talk briefly about custom Windows distributions specifically designed for peak performance, for old and new computers alike.

Since the last video about optimizing Windows instructed you to remove GitHub integration from IntelliJ, today I’ll show you what I use to synchronize my code across machines or simply share it online.

Here’s what we are going to cover:

• Using GitHub Desktop: How to synchronize and publish code to GitHub without Git always running in the background for maximum performance and stability.

Today you’ll learn how to export your mod to a single jar file you can publish on Curse or send to your friends.

Here’s what we are going to cover:

• Compiling your mod: How to build your mod into a jar file which can be installed to any Minecraft using Forge.

In this lesson we’re going to be finally starting with modding concepts. I understand there’s a lot of weird stuff in Forge and therefore will begin simply by showing you custom items.

Here’s what we are going to cover:

• Creating a custom item: Registering a custom item within Forge registries in the code, as well as the assets folder. I’ll walk through the item model file, its texture as well as your overall mod language json file.
• Textures: How to properly design a 16×16 texture for Minecraft. I’ll walk through a free app as well as Photoshop.

When I first learned Forge I got stuck 100x of times and wanted to quit 200. I discovered two levels of motivation that helped me push through resistance. Keep in mind it’s completely normal to feel this way and all of us do.

Today, I’ll be explaining Level 1 to this motivation hack so you can stay sharp while maximizing productivity and achieve all goals you have set for yourself in the onboarding survey.

Here’s what we are going to cover:

• Motivation hack level 1: How to stay sharp, focused and maximize productivity even when you don’t feel like doing it today.
• Preventing frustration and overwhelm: How to reduce the risk of losing motivation and quitting prematurely before achieving your goals.

While the last lesson dealt with mental blocks, today we’ll be dealing with actual custom Minecraft blocks.

Here’s what we are going to cover:

• Adding custom blocks: How to create and design custom Minecraft blocks, all including the necessary code, the assets, block states as well as the texture.
• Deep understanding to avoid pitfalls: Understanding how items/blocks are registered within Minecraft and why we have to register them the way we do.

In this lesson we’ll continue building our custom blocks, namely I’ll teach you stairs and slabs.

Here’s what we are going to cover:

• Using existing Minecraft models in new ways: Adding your own stairs/slabs to Minecraft using the existing stairs/slab renderer.

Today I’ll be going through some of the most popular blocklike structures using existing Minecraft rendering, and I’ll teach you how to apply it to your own custom blocks.

In simple word, we’ll be making some buttons, doors, walls, fences etc.

Here’s what we are going to cover:

• Buttons & pressure plates: Add your own custom buttons and pressure plates including drops and custom behavior.
• Fences, fence gates & walls: How to make your own fences, fence gates and walls and make them connect to each other.
• Doors & trapdoors: How to properly register and render doors and trapdoors. We’ll be using the “cutout” rendering technique.

In this video, I’ll show you how to design and add items to your own creative tab window.

Here’s what we are going to cover:

• Custom creative tabs: How to register custom creative tabs for creative mode.
• Adding items: Populating our creative tab with our own custom items.

Today I’ll show you the various crafting recipes you can have within Minecraft, and how to make your own.

Here’s what we are going to cover:

• Recipe shapes: Shaped and shapeless recipe.
• Workbench recipes: Creating custom recipes for the crafting table.
• Furnace & blasting recipes: How to add your own smelting and blasting recipes.
• All other recipe types: I’ll show you where to find native Minecraft recipes and how to design your own for any block.

In this lesson, you’ll learn a simple concept of adding a custom fuel to furnace/blasting furnace.

Here’s what we are going to cover:

• Adding fuel items: How to add your own custom fuel items in Minecraft.

Today we’ll be making custom food!

Here’s what we are going to cover:

• Adding edible items: Making our custom banana item edible.

If you are familiar with Bukkit, this lesson will make a lot of sense. I’ll show you how to add custom item lore, also known as a tooltip.

Here’s what we are going to cover:

• Adding item lores: How to place a custom item tooltip with colors for any custom item.

In this lecture, I’ll show you how to properly make custom items or blocks drop themselves as well as how to make blocks drop experience when mined in survival.

Here’s what we are going to cover:

• Item & block drops: How to make our items or blocks drop themselves depending on their state (such as double-step will drop 2x steps).
• Drop experience: How to make blocks drop experience when mined in survival

In this lesson I will teach you how to open default block classes (works for any class really) and modify their properties.

PS: There is a next level to it for non-static properties as well, that is being covered in the Flowers lesson.

Here’s what we are going to cover:

• Opening vanilla classes: How I find vanilla classes and hack into their properties.
• Adding composer items: An example of this is when I will add custom composer items.

Today you’ll learn the basics of block properties (we’ll dive deeper into this in Week Two) and we’ll be making our custom farming crops!

Here’s what we are going to cover:

• Block properties: We’ll be working with block states and block properties to properly handle crops growth by using the IntegerProperty age.
• Adding custom crops: How to make a custom crop block, seeds and the finished item.
• Age-dependent drops: How to customize what the crop drops based on its age (or any custom property).

In this video you’ll be adding custom vegetation and pot items!

(I will show you how to naturally spawn it to your world later.)

Here’s what we are going to cover:

• Adding flowers: Creating our custom plants and decoration.
• Potted flowers: How to properly add a flower to a pot. As a bonus, I will even teach you how to give yourself a potted item to creative inventory which vanilla client does not normally do.

Elon could not stand Forge craziness and people losing motivation over mods so he decided to explain his simple 5-step process for making things. Obviously I am being satiric, but if you want to get a lot of things done and learn from your mistakes, watch this video.

Here’s what we are going to cover:

• Make your requirements less dumb: It’s particularly dangerous if a smart person gave them to you as you might not question them enough.
• Delete parts of your process: If you’re not adding back then you’re not deleting enough.
• Simplify: Don’t optimise if it shouldn’t exist
• Accelerate cycle times: Don’t go faster if you haven’t worked on the other 3 things first.
• Automate: Don’t reverse these 5 steps
