Socket programming for online game development

We'll teach you essential Windows System programming skills for developing games and applications for Windows.

It seems the mainstream graphics API has shifted from D3D11 to D3D12. D3D12 supports attractive features but has a steep learning curve. However, I believe that with gradual learning, individuals can also create games using the D3D12 API. Therefore, based on my experience building a game directly with D3D12, I aim to provide the knowledge base needed to challenge D3D12 game programming.

Introduces the knowledge and approaches needed to develop your own engine.

DirectX 12 supports real-time Raytracing, allowing high-quality graphics to be implemented with concise code. However, due to the high barrier to entry, programmers who directly utilize it are rare. Based on experience applying Raytracing to actual games, this course will help you develop your own Raytracing engine.

Let's learn Windows debugging techniques that no one tells you about.

This course continues from D3D12 Programming Basics. After implementing basic rendering features, it explains the features and approach needed for actual engine development using them.

This tutorial introduces how to use Tiled Resources in D3D11/12.

Introduces the purpose and programming method of Mesh Shader, a new feature added in D3D12.

This course provides the basic knowledge needed for those with experience in D3D9/10/11 or OpenGL to adapt to D3D12 programming.

During our school days, the 'click' sound we heard in the computer lab... that was Minesweeper. In this course, we'll recreate those memories by implementing it with Python. Whether you're a beginner or even someone encountering Python for the first time, by following along line by line, you'll find that your very own Minesweeper game has been completed before you know it.

This is a high-level engine game development course for complete beginners with no coding experience. If you are new to game development, start with this course!

You can learn the basic theory and features of TCP sockets. You can learn various socket options and task-based asynchronous programming.

This course is designed to help complete beginners overcome the most common challenges in game development: understanding Unity, learning C#, and knowing how to turn ideas into real, playable games. Through years of teaching beginners, I have learned that students struggle most with complex explanations, disconnected theory, and lack of real practice. That’s why this course follows a clear, step-by-step, hands-on approach, where every concept is explained simply and immediately applied in real game projects. Students will build full 2D games from scratch, learning how to create player movement, enemies, levels, UI systems, animations, audio, and complete game flows. By the end of the course, learners will not only understand how 2D games work but will confidently create and export their own games using Unity and C#.

This course is for those who want to develop packet analysis programs like Wireshark and various network solutions using the Npcap library.

Learn C# for developing applications like ASP.NET, Winform, WPF, and MAUI that run on the .NET Platform.

This lecture is written from the perspective of a non-major, so it may be lacking. However, as a non-major, I may know better what is difficult to understand.

For those aiming to pass the "Network Specialist Examination": This course is a learning program that condenses only the key points of the IPA Network Specialist Examination. It focuses on themes directly connected to passing the exam and is designed to help you acquire knowledge efficiently. Rather than emphasizing volume, we carefully select and explain "the essential parts you must master to pass"! Let's work hard together toward passing the Network Specialist exam!

This course is a basic introductory program for learning how to utilize the Raspberry Pi Pico and various sensors. Learners can understand the basic functions of the Raspberry Pi Pico and develop the ability to control various sensors using it. This course is structured to gradually improve sensor utilization skills based on a fundamental understanding of the Raspberry Pi Pico.
