[2025 Edition] Unity x C# Introduction | 2D TD Game Development | How to Create a Plants vs. Zombies Style Character Placement Battle

Unity 6.3 LTS Compatible | Introduction to 2D Game Development: Learning Background Scrolling, Score Management, and Saving High Scores

Build a competitive tower defense game in Unity from scratch using C#, featuring both offensive and defensive characters. This practical course teaches you how to design characters with unique traits and implement strategic battle mechanics.

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.

Implement a Clash Royale-like game from scratch in Unity using C#. A practical course where even beginners can create character summoning, auto-battles, and wave systems.

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

You can learn design patterns to implement flexible and scalable object-oriented programming. Learn various patterns that can be used in the real world and apply them to your projects and code refactoring.

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.

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!

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.

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.

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.

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.

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.

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.

This is a lecture for people who are starting development for the first time. It's about programming thinking, which should come before development languages or UI frameworks.

Let's design, implement, and develop while learning the basic and object-oriented concepts of the C++ language!

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 is an introductory Java course designed so that even those starting programming for the first time can follow along. You will systematically learn everything from JDK 21 environment configuration to variables, data types, control flow statements, arrays, strings, and the core concepts of Object-Oriented Programming (OOP) such as classes, inheritance, polymorphism, and exception handling. Rather than simply listing syntax, we explain "why it works this way" to help you build a solid foundation.

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.

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.
