Game Programmer Job Secrets (Large Company Actual Interview Collection)

This is a lecture where you can easily learn important mathematical concepts used in games. People who are well-versed in mathematics take this knowledge for granted, so they cannot teach it assuming you know nothing. I explain from a beginner's perspective, truly assuming you are a non-major.

You should stop programming by searching for and copying source code from Google. It is important to code freely on your own without relying on other people's code.

I had previously created a simple engine structure with DX11, and now this is a course where the functionality implementations of the engine transitioning to DX12 are implemented in earnest. From the standpoint of having developed my own engine for a long time, I have made efforts to make it easy to approach so that many people can develop their own engines. Stop struggling with GPT, Google, and searching for materials anymore.

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.

Easily learn data structures and algorithms, which were difficult to learn with C++, in easy steps. Unlike typical lectures, this course combines data structures and algorithms, allowing you to learn them simultaneously while considering their interrelationships.

This is the process of refactoring a game engine made with C++ using the DirectX 11 library. It was developed by inferring internal code, allowing you to think about the internal principles of the Unity engine. This is not a project at the level of a rendering program typically covered in academies/lectures. It builds a real game engine incorporating various technologies, from the build system and scripting.

This is the process of creating a game engine using C++, similar to the Unity game engine. It was created by inferring the internal code, and through this, we can think about the internal principles of the Unity engine.

This course is for beginners who are wondering "What should I do now?" after building a basic knowledge of Unity. You can learn the core code of a small-scale hyper-casual game in a short but intense way. (All resources and PDF materials used in the course are provided.)

This lecture aims to be a welcome resource for those who dream of becoming game programmers. 1) We share tips on resumes & cover letters, portfolios, and interviews needed for employment. 2) We share the story that continues from zero, through becoming a junior, and beyond.

This course is built from real experience teaching beginners who often feel lost when starting Unity and game development. Many students struggle with understanding how scripts work together, how game mechanics are connected, and how to turn simple ideas into a complete playable game. In this course, I guide students step by step, explaining every concept clearly and practically. Instead of overwhelming theory, we focus on building a real 2D space shooter game from scratch. Every script is written and explained line by line so students understand not only what to do, but why it works. The goal is to remove confusion, build confidence, and help students think like game developers. By the end of the course, students are able to understand Unity 2D fundamentals and confidently start their own game projects.

This course is designed for beginners who want to learn Unity 3D through a clear, practical, and problem-solving approach. Based on real teaching experience with beginners, this course focuses on explaining concepts step by step, in simple language, without assuming any prior knowledge. Common beginner problems—such as understanding GameObjects, movement, shooting logic, enemy behavior, and UI—are addressed carefully with hands-on examples and clear explanations. Instead of overwhelming students with theory, each lesson builds directly on the previous one, helping learners understand why things work, not just how to copy code. By following the full project from start to finish, students gain confidence and a strong foundation in Unity 3D by creating a complete and playable Space Invaders–style 3D game.

Anyone who is a C/C++ developer can get started. You can quickly learn MFC Windows programming by selecting only the core. We also provide a 1200-page textbook.

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#.
