[Unity 6] Learning by Doing: Real-World 2D Platformer Game Development

This is a practice-oriented course where you will create a 2D idle game from start to finish using Unity 6. You will implement the core features required for idle game production step-by-step, including game world configuration, player and enemy object creation, basic attacks, Behavior Tree-based enemy AI, currency systems, stat upgrades, Memory Pool systems, skill equipping/unequipping, equipment data management, inventory, gacha systems, stage systems, and finally, building and deployment. This course covers a more advanced structure than the previous Top-Down Shooting game production. Beyond simply creating features one by one, you will improve the architecture to manage multiple objects integrally using MemoryPoolManager, PoolOriginKeyHolder, and PoolKeys, and learn how to apply or remove stat effects based on equipping and unequipping equipment/skills. Additionally, you will gain hands-on experience with systems frequently used in actual idle RPG/clicker games within a single project, such as Google Sheet-based equipment data loading, equipment management systems, inventory, gacha, and stage systems.

This course is for beginners who want to develop games with Unity, and explains in detail everything from installing Unity to the basic knowledge required for 2D/3D game development. (All resources used in the course can be downloaded by clicking the “Course Materials” button at the top of the video.)

This is a step-by-step process of developing a chapter/stage-based Top-Down Shooting game like "Archero" from scratch using Unity 6. (All resources and PDF materials used in the lecture are provided.)

This course is for beginners who are interested in "online game development" after building a solid foundation of knowledge about Unity and creating a simple game. You can learn how to create an online game using "Backend", which even beginners who do not know about servers can easily use. (All resources and PDF materials used in the course are provided on the YouTube link.)

This is a practice-oriented course where you will build a 2D tower defense game from scratch using Unity 6. You will implement core features required for the tower defense genre step-by-step, including map creation using 2D Tilemaps, enemy spawning and movement, tower placement, tower attacks, health/gold/wave systems, tower info UI, tower upgrades and selling, as well as specialized towers like laser, slow, and buff towers. By following this course, you won't just be copying functions; you will learn how to utilize Unity's Tilemap, Prefab, Coroutine, Raycast, UI, and ScriptableObject within an actual game development workflow.

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 is a course for beginners who are wondering "What should I do now?" after building foundational knowledge of Unity. You can learn the core code of games in a short but intensive way by creating Hyper Casual Games that are not large in scale. (All resources and PDF materials used in the course are provided.)

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

This course is designed for beginners who want to create various games with Unity. You can easily and thoroughly learn how to create small-scale Hyper Casual Games. (All resources and PPT used in the course can be downloaded from the first video [Project Basic Settings] of each lecture.)

Learn how to design various shaders and visual effects that can be used in games using Unity 6 Shader Graph. This is a step-by-step lecture from basic to advanced techniques for beginners and experts alike.

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.

It's an undeniable fact that mathematics is essential for game developers. Instead of excessively deep traditional math lectures, learn all the mathematical techniques you can use right away!

This course is an FPS game that runs on AR using Unity. You can learn about AR projects from AR settings to build and run.

Complete a Match-3 game by connecting Unity and Claude Code via MCP, allowing you to request development from AI even without coding knowledge. You can experience the entire process of practical game development, from environment setup to game system implementation, mobile optimization, and ad monetization.

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.

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.

We will implement player controls, animations, and an attack system using Claude Code, and develop boss AI detection, pursuit, attack patterns, and phase transitions using the Behavior package. We will guide you through a step-by-step tutorial.

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.

How to easily create games with AI, launch them on the Toss app with 30 million users, and monetize them.

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.

This is an introductory VR development course that teaches you how to connect VR equipment and develop VR content using Unity. Since the marketability and prospects of VR can already be found in many contents, we have not covered them and have only extracted the core elements needed for actual development. If you want to learn how to develop VR in an easy and fast way that you can use for a long time, come here!

Learn the basics of collaboration that you can use in your Unity collaborative projects. We will use Git Bash instead of Github Desktop to work directly with Git. If you don't understand something, please ask!

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.
