Learn the principles of Diablo 1-style PCG dungeon generation by implementing its structure in the console, with the theme 'Technology Supporting Game Development in the AI Era'. Expand this to 3D in Unity to complete a generation pipeline equipped with seed-based dungeon generation, mesh placement rules, and debug tooling. Through sample code and hands-on practice, connect to AI-assisted art production workflows, enabling you to create immediately applicable dungeon crawler prototypes.

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.

The Code Puzzle Clear Challenge is a 4-week intensive training course based on "Learn to Code 1" in Swift Playgrounds, designed to develop "computational thinking" by giving commands to make a computer move as intended. By solving puzzle missions in each session, participants naturally learn to break down problems into smaller steps (decomposition), recognize patterns to organize repetitive rules using for-loops or functions, and make logical judgments to change actions based on specific situations. Beyond simply finding the right answer, participants reach a level where they can explain and refine "why they solved it this way."

For learners starting programming for the first time, C language can feel difficult due to unfamiliar concepts such as variables, operators, conditional statements, loops, functions, arrays, and pointers. This course is an introductory C language program taught directly by Professor Chang-hyun Lee, a 25-year veteran developer and the author of "C Language Alone." Rather than simply memorizing C language syntax, this course provides step-by-step explanations of why each syntax is necessary, how it operates within a program, and how to solve real-world problems through code. Starting from the basic concepts of programming, you will learn the core foundations of C language—including variables and data types, operators, conditional statements, loops, functions, arrays, and pointers—one by one. Through assignments for each part, you will gain hands-on experience writing code and solving problems based on what you have learned. Based on 25 years of experience in development and education, this course guides beginners to firmly establish their programming fundamentals in C language.
