This is an introductory course for beginner game designers who find quest design overwhelming. It helps you move beyond quests that don't go past the "kill X monsters" level, and explains step-by-step why players take action and how choices become experiences. Centered on real commercial game examples and the designer's thought process, it teaches you the fundamental design methods for connecting quests with story, gameplay, and systems.

This course is not just about "knowing how to use" C++, but about elevating your skills to a level where you can "explain how it works." It is dedicated to students who want to properly learn object-oriented programming.

This lecture reveals employment secrets to prepare you for game programmer interviews. It handpicks frequently asked interview questions for game programmers.

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.

Working as a game designer, there are often moments when you feel lost, not knowing how to plan sound or how to collaborate with the audio team. In particular, questions like "What makes good sound?", "Why does my game lack impact?", and "Why don't scene transitions/UI/combat/ambient sounds connect into a cohesive experience?" are among the most challenging areas for designers with limited experience. This course is designed for designers with these concerns, explaining the principles of sound design in a designer's language and helping you understand step-by-step, aligned with actual workflow, what role sound plays in games and how it should be designed. Focusing on core concepts and real-world examples that make up game sound— such as sound direction, impact feel, feedback, layering, ducking, and trigger design— this course explains things concretely and practically so that even beginner designers without audio expertise can easily understand and immediately apply them to their work. After taking this course, you won't be a designer who relies on vague intuition saying "just do it like this," but rather one who understands various game sound techniques and can proactively lead audio quality.

This course is a basic introductory program for learning how to utilize the Raspberry Pi Pico and various sensors. Learners will understand the fundamental functions of the Raspberry Pi Pico and acquire the ability to control various sensors using it. Based on a foundational understanding of the Raspberry Pi Pico, this course is structured to step-by-step improve your skills in utilizing sensors.

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.

Learn various design principles needed to write object-oriented code, focusing on working code.

This is a course where you can learn UML and object-oriented design even without programming experience. Concepts are explained through everyday examples (cafes, libraries, shopping malls), and you'll learn 9 types of UML diagrams step by step. You'll develop design skills that can be immediately applied in practice using theory and PlantUML.

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.

Through the 25 patterns of OODP, you will learn various ways to design software in an object-oriented manner.

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.

When learning Swift, the iOS programming language, it can be confusing when multiple concepts appear all at once. That's why I created this course with the principle that "when understanding a new concept, only previously learned concepts should be used." So this course is meticulously designed with a sequential structure between concepts, where only one new concept appears at each stage, and no other unfamiliar concepts appear at all. One concept per minute, 180 concepts total. From the basics of variables and constants to understanding memory structure from a CS perspective, and even the latest syntax for asynchronous processing. In 3 hours, you'll learn 180 core concepts in the designed order.

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!

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!

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.

PCG (Procedural Content Generation) is a design approach that automatically generates game content based on rules and conditions. It is utilized for various content such as maps, items, events, and quests, and is currently widely used throughout the game industry to improve development efficiency and gameplay variety. PCG is no longer limited to specific genres or technical teams; it has become one of the fundamental concepts that game designers must understand. PCG is often misunderstood as merely a mathematical or programming technique, but in reality, the most important aspect is the planning-stage choices and design that determine "what kind of experience to create repeatedly." This course is an introductory lecture focused on understanding and utilizing PCG from a designer's perspective. Rather than teaching how to write code, it gradually explains why PCG is necessary, what problems it solves, and how it is used in game design, centered on principles and case studies.
