Game Algorithms You Must Learn by Lee Deok-woo

Programming is a science of logic and reason. Data structures are essential for more independent thinking and proactive coding. This lecture is designed to explain various terms and concepts for non-majors. Based on the content actually taught in offline classes, you can learn about the types and characteristics of data structures through simple code design.

Programming is a science of logic and reason. Data structures are essential for more independent thinking and active coding. This lecture is designed to explain various terminologies and concepts for non-majors. Based on the actual content taught in offline classes, you can learn about the types and characteristics of data structures through simple code design.

This lecture is for those who tried to study advanced algorithms but feel lost on how to approach problems with just the basic data structures and algorithms found in books.

An era where anyone can create games with AI. Learn the efficient framework and core systems for incorporating AI-generated code. Quickly complete your game on top of already-finished, stable systems. The secrets of AAA game developers are revealed.

You will understand the basic functionality and memory operations of Unity and learn how to create a game that runs a full cycle, not just a prototype.

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.

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.

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 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.

Slowly study the C language, which includes the basics of program development that developers need to know.

✅ Out of the entire series (1) ~ (7), (4) data structure, algorithm, object-oriented, programming language ✅ CS101 series lectures - From basic computer theory to the latest practical examples - Provides a wide range of basic knowledge

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.

This course is an FPS game that runs on AR using Unity. You can learn about AR projects from AR settings to build and run.

Are you a non-major who doesn't know how to start learning C language? Did you learn C language as a major in school, but still can't write code? What's the point of studying C language for a long time? When you can't even create a single line of code properly... I'll pass on the know-how so you can program yourself. In this course, together with an experienced senior developer, you'll gradually learn C language grammar and application methods, and I'll guide you to a level where you can work on simple projects.

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.

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.

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!

This course goes beyond simple grammar explanations and focuses on developing C++ programming skills that can be applied immediately in the field. Throughout my teaching, I have directly addressed common challenges faced by many learners—such as struggling to understand the STL or feeling confused by file handling and exception handling concepts. Based on this experience, I provide step-by-step explanations to ensure even complex concepts are understood easily and clearly. Furthermore, this course is not just about delivering theory; it is structured around: 👉 "Why this concept is necessary" 👉 "How it is used in actual code" 👉 "How it is applied in professional practice"

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.

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.
