Intro to 3D Game Development Masterclass in Godot! (2024) by Thomas Yanuziello

Build a complete 3D action-adventure game from scratch in Godot 4.3. This course walks you through every system you need for a modern game: third-person character controls, menus, save/load, branching dialogue, inventory management, and a full combat system with weapons, blocking, and dodging.

🎯 What you’ll learn

• Build a third-person character controller with walking, jumping, and camera controls.
• Create a full game infrastructure including menus, settings, saving, and loading.
• Design an event management system for branching dialogue and cutscenes.
• Implement an inventory system with pickup, use, equip, and NPC trading.
• Develop a dynamic combat system with attacks, blocking, dodging, and projectiles.

✅ Requirements

• Skills: No experience necessary; everything is taught step-by-step.
• Tools: A computer capable of running Godot 4.3.
• Hardware: Minimum 4GB RAM, dedicated GPU recommended for 3D rendering.

📝 Description

This isn’t another “make a cube move” tutorial. You’ll start with a blank project and build a real, scalable game infrastructure. The course focuses on GDscript and Godot 4.3, teaching you how to write modular, reusable code that you can drop into your own projects.

The curriculum is split into five logical chunks. First, you get a solid third-person character controller with walking, jumping, and a camera that doesn’t make you motion sick. Then you add the boring-but-essential stuff: pause menus, title screens, save/load systems, and background music. From there, things get interesting with a full event management system that handles branching dialogue, character animations, camera cuts, and progress flags. You’ll build an inventory system where players can pick up items, equip gear, trade with NPCs, and manage consumables. Finally, you’ll implement a combat system with lock-on targeting, melee attacks, blocking, dodging, and ranged projectiles.

Every script is explained in detail, and the project files are available on GitHub after each lesson. The assets come from free packs by KayKit, Penzilla, and others, so you can focus on code, not art.

🧑‍🎓 Who this course is for

• First-time game developers who want to build a complete 3D game.
• Experienced 2D developers looking to transition into 3D with Godot.
• Anyone who has finished beginner tutorials but wants to learn scalable game infrastructure.
