Conversation loops, tool calling, permissions, prompt assembly — learn the core principles of Claude Code by visualizing them through 3D interactive materials. Translate the structure you understood from the materials directly into code to complete your very own 'Mini Claude Code (Harness)'.

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.

This is an all-in-one curriculum for game programming beginners who are unsure of where to start. It is a comprehensive curriculum that covers the basics of game programming, including C++, data structures/algorithms, STL, game mathematics, Windows API, and an introduction to game servers.

This is a basic C# programming course for those who do not have basic programming knowledge. It is not a class that focuses on memorizing grammar, but rather summarizes only the most necessary parts.

In just one year, an AI-driven cataclysm has occurred. Is it over for game programmers forever? Let's predict the future direction of the industry and establish a tailored strategy.

This course covers core computer science knowledge such as networking, multi-threading, and operating systems, and teaches MMORPG technology by building a game server from the ground up. It provides a comprehensive overview of the knowledge that a new server programmer should know, building a foundation that allows them to adapt to any project without feeling overwhelmed.

This is an introductory course where you learn the core concepts of Claude Code through a 3D office analogy. From hiring a single robot in an empty office, giving it a brain and a heart, equipping it with tools, permissions, and memory, to eventually having multiple robots work together as a team—each concept unfolds as an office scene. You will master every concept by interacting with the digital course materials and complete your learning through hands-on practice on your own computer.

This is an introductory course on creating multiplayer games in UE5. You will practice everything from theory to implementation of listen server-based multiplayer game development by recreating the actual game [Last Man Standing].

This course teaches the essential CS knowledge required for web development using AI. If you don't understand the principles of servers, databases, and deployment, "Vibe Coding" will inevitably hit a wall at some point. Through interactive textbooks, you will quickly learn essential concepts, enabling anyone to complete a web project using Vibe Coding.

This is a course where you study core major knowledge such as network, multi-threading, and operating systems, and learn MMORPG technology by building a game server from scratch.

The AI era is bringing many changes to the gaming industry. Let's explore how AI-based content generation is impacting the game industry.

This lecture covers the reality of being a game designer, which many people misunderstand, and the direction for the future.

This is a course that covers the entire process of working with the Unreal Engine based on C++, in a shallow and quick way.

This course will teach you about Entity Framework Core, a .NET ORM for seamless database integration.

This is a lecture practicing Unity development by creating a game similar to Supersense's hit, Burger Please.

This lecture will delve deeper into the various features of ASP.NET Core. You will practice what you have learned through Facebook authentication practice.

Beyond the first wave of AI, the era of Physical AI, represented by autonomous driving and robotics, is arriving. To prepare for a future where AI permeates transportation, delivery, manufacturing, and service sectors, we will understand the changing job market and establish specific learning strategies and career directions for survival.

The AI era is bringing many changes to the gaming industry. We will predict how the future will change and how to prepare for it, and explore the ideal talent profile and study strategies for the gaming industry.

This is a UE5 source code analysis lecture conducted by a top-level Unreal Engine expert.

This is a course where you will learn the structure of the Lyra project provided by UE5 step-by-step by recreating its core components.

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.

"Skip the formulas and code—focus on the principles and visual results!" This lecture was designed for 3D artists and modelers who have given up on understanding PBR (Physically Based Rendering) due to technical barriers. To ensure you can apply it directly to your actual work without any programming knowledge, we explain the visual principles of how light reacts on object surfaces. Basic Physics of Light: We break down intimidating terms like speed of light, illuminance, and luminance into concepts that are easy for artists to understand. Visual Implementation of Surfaces: Learn the Fresnel characteristics inherent in all objects and light reflection based on roughness through 'visual principles' rather than code. Advanced Lighting Techniques: Analyze what difference IBL (Image-Based Lighting) and Global Illumination make in actual modeling results. Understanding the Rendering Equation: Elevate the quality of your work by understanding the Rendering Equation—the core of rendering engines—not as a formula, but as a 'promise' that shows the flow of light. #PBRforArtists #3DModelerCourse #NoCodeGraphics #PhysicallyBasedRendering #PBRPrinciples #RenderingEquation #FresnelEffect #GraphicsforNonMajors #3DRenderingBasics #CGArtist #IntroToRendering #VisualPrinciplesLecture #3DWorkTips

Are PC effects breaking or slowing down on mobile? Based on know-how gained through countless trials and errors, I will share the core principles and optimization strategies.

In just one year, an AI-driven cataclysm has occurred. Is it over for game programmers forever? Let's predict the future direction of the industry and establish a tailored strategy.

Even if you are new to Unreal Engine, taking this course will help you become familiar with it in just one day. It covers the basics thoroughly and only the necessary parts efficiently.

Want to implement UI effects exactly the way you want, but tired of enduring the engine developer's 'annoyed' look? Does your company also expect you to handle UI effects? Now, it's time to build it yourself! By taking this course, you'll be able to understand and apply other effect creation methods that once seemed too difficult!

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.
