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.

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 PvZ-style tower defense in Unity from scratch using C#. A practical course where even beginners can learn to build grid-based character placement, enemy pathing/blocking, and coin management.

This hands-on course focuses on building a code structure that is easy to modify and extend, based on a completed 2D tower defense game. Tower functionality that was previously concentrated in a single class is separated by responsibility, while object pooling, event-driven UI, and ScriptableObject-based data separation are introduced step by step. The course also examines issues that can arise when multiple systems work together, such as stacking buffs and slow effects, enemies being returned more than once, and waves starting multiple times. Using the improved structure, you will add area-of-effect, poison, chain-attack, and stun towers, as well as create an editor tool that automatically generates movement path data for the map. By modifying the code yourself and checking the results, you will learn the criteria for grouping common functionality and the reasons for dividing responsibilities.

Do you have a game idea but feel overwhelmed by the thought of organizing it into a design document? In Part 1 of this practical game design series with a game designer from one of the industry’s major 3N game companies, you’ll learn how to turn your ideas into the documents and rules needed for development. Starting with an understanding of a game designer’s role and the game development process, we’ll gradually explore design intent and documentation, UI/UX, data tables, and system rules. Build on your passion for games with a solid foundation in game design, and grow into a game designer who can explain your ideas with clear reasoning and documentation. From writing your first design document to preparing for a career as a game designer, let’s take the first steps together.

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.

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.

For learners who find connecting a PLC and Unity daunting, complete a digital twin using only a PC, backed by real-world integration experience.

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.

Turn your dream of game development into reality! Learn firsthand from a current AAA game developer about strategies for landing a job or changing jobs at Korean game companies!

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.

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.
