FPS game made with Unity AR

Once you are able to move characters, create monsters, and implement various game features in Unity, the next important step is how to design your code. As a project grows, these concerns begin to arise: "The code is getting more complex; how should I manage it?" "Do I have to keep modifying existing code every time I add a new feature?" "When and why should I use Singletons, Managers, Events, and FSMs?" In this course, you will learn core design patterns and code structures that every Unity developer must know, along with practical Unity examples. By learning about Singletons, Managers, ScriptableObjects, SOLID, Delegates, Actions, Events, FSM, Object Pooling, JSON, and more, the goal is not just to follow along and write code, but to understand why each concept is necessary and in which situations they can be applied. This design experience will serve as a crucial foundation when designing and developing your own game projects or building a portfolio for employment. Moving one step beyond simply 'making the game work,' Growing into a Unity developer who considers the project structure and can explain the reasoning behind their code design. That is the goal of this course.

Experience the joy of game development by creating your own music game with Unity. Learn how to make your own music game easily and enjoyably!

This lecture systematically covers everything from the basics to practical exercises for those who are new to Unity. You can learn the basic usage of Unity and the game development process by creating a simple dodging game yourself.

This is an introductory VR development course that teaches you how to connect VR equipment and develop VR content using Unity. Since the marketability and prospects of VR can already be found in many contents, we have not covered them and have only extracted the core elements needed for actual development. If you want to learn how to develop VR in an easy and fast way that you can use for a long time, come here!

Implementing AR Augmented Reality Apps with Simple Coding

This is a training-style lecture for absolute beginners who are making their first game. After learning the core functions of 2D games using Unity, you will use it to make a 2D dungeon tank shooter game.

Using Unity based on the C# language, you will learn how to create a defense game step by step.

Complete the core battle system of a Unity 2D martial arts idle game from scratch using the AI coding agent Claude Code. We will build a starter kit codebase that is immediately expandable in practice—covering auto-battle, object pooling, stage systems, and boss battles—while experiencing the entire development loop from requirement design to debugging alongside AI.

This is a supplementary course from the author of NGUI Unity 2D Game Programming: Learn by Following.

Complete a Match-3 game by connecting Unity and Claude Code via MCP, allowing you to request development from AI even without coding knowledge. You can experience the entire process of practical game development, from environment setup to game system implementation, mobile optimization, and ad monetization.

How to easily create games with AI, launch them on the Toss app with 30 million users, and monetize them.

It's an undeniable fact that mathematics is essential for game developers. Instead of excessively deep traditional math lectures, learn all the mathematical techniques you can use right away!

In this course, you will build a system that directly parses DWG drawings in Unity and automatically converts them into actual 3D walls based on lines and polylines. After completing the DWG → 3D map automatic generation pipeline, you will also implement map editor functionality that allows you to freely place various objects on the generated space and save/load them in JSON/DB format. Finally, by integrating essential features used in real-world digital twins such as heatmaps, status displays, and real-time data reflection, you will complete a digital twin project from start to finish that can be immediately applied in industrial settings.

Learn how to design various shaders and visual effects that can be used in games using Unity 6 Shader Graph. This is a step-by-step lecture from basic to advanced techniques for beginners and experts alike.

In the era of agents, true skill comes from 'control.' You will perfectly master the operating principles of agents by building the core architectures of Claude Code—Agent, Tool, MCP, Skill, and AgentTeam—from scratch.

Build a full-scale tower defense game from scratch in Unity using C#. This practical course implements the mechanics of a strategy game—where you place characters to prevent enemy invasions—by breaking them down into individual functional components.

For those who have hesitated to adopt Git and Github for collaboration or have given up for various reasons, this introduces Git basics and the GitFlow branching strategy. It's structured to help you learn Git and Github tailored to the specific characteristics of Unity projects.

We will implement player controls, animations, and an attack system using Claude Code, and develop boss AI detection, pursuit, attack patterns, and phase transitions using the Behavior package. We will guide you through a step-by-step tutorial.

Learn the basics of collaboration that you can use in your Unity collaborative projects. We will use Git Bash instead of Github Desktop to work directly with Git. If you don't understand something, please ask!

Game development is a complex field that goes beyond simple coding to encompass performance optimization, architecture design, collaboration, accessibility, and monetization. This course summarizes the sessions from GameDev Day 2025, a global event hosted by JetBrains, and captures the real-world challenges and solutions that professional developers face in the industry.
