Creating Mobile Games with ChatGPT Codex: From Building 8 Games to Store Submission

If you’ve ever had trouble determining whether the quality of responses declined after changing a prompt or model while building a service using an LLM, this course may be the solution. You’ll learn how to create your own evaluation criteria and automatically identify responses that have changed.

You don’t need to know how to code. Once you learn how to “give the right instructions” to AI tools like Claude and Codex, you can create everything yourself—from cinematic websites and motion-graphics promotional videos to AI short dramas, ads, and even podcasts made with your own voice. You’ll receive more than 20 ready-to-use kits containing projects that are actually being created and used, and we’ll show you the entire process exactly as it appears on screen: handing the folder over to AI and converting it to your brand → fixing only the parts you want with a single screenshot → completing Vercel deployment and domain connection. Recorded in October 2026 using the latest AI tools (Claude Opus 5.5 · GPT-6.1 · Grok Build), this course focuses on workflows that continue to work even when the models change.

Learn about the rising Godot Engine, starting with the basic concepts, and immerse yourself in creating your own game, experiencing the light yet powerful productivity of the Godot Engine firsthand!

You can learn the basic principles of run games like Cookie Run and create Unity games through practical projects in Unity by genre.

Now your imagination becomes the ultimate game design document! With AI, you can have fun chatting as if you were building with LEGO and complete your first game. Try Google Gemini Pro for free!

AI is only as good as you are. Learn vibe coding properly in three steps: how to use AI → essential foundational knowledge → project development. For those who want to learn vibe coding the right way, we deliver the core concepts that remain unchanged regardless of which AI you use, broken down into bite-sized pieces.

"Why did the AI write this code?" or "Why can't it remember what I just said?" The frustration you encounter when using AI tools like Claude Code stems from not knowing how the tool actually works. This course flings open that black box. Over 25 lessons, we will build our own Coding Agent from scratch that functions exactly like real-world professional tools—giving the LLM 'eyes' to see files (Read), 'hands' to fix code (Edit), and 'feet' to execute commands (Bash). This isn't just about learning how to use a library. You will gain hands-on experience by implementing code to understand how AI perceives project structures, why it loses its memory during long conversations, and how to solve those issues technically (Sliding Window, Summary). Through this process, you will evolve from being a mere 'user' of AI tools to an 'AI provider' who understands the underlying principles and can customize and evaluate tools to fit your specific needs.

Non-Majors Welcome: Real-World Vibe Coding Projects Created Through Conversations with AI

Even without knowing a single line of code, deploy the idea you came up with today as a working web service today. A hands-on course that takes you through planning, design, functionality, data, and deployment all at once with Google Antigravity.

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.

Even without coding experience, you can create AI agents to handle repetitive tasks using Claude Code and Codex. From installation and your first hands-on practice to Skills, MCP, and meta-prompting, as well as projects involving reports, quotations, trend analysis, and content creation, you’ll learn step by step how to operate and optimize them, ultimately building an automation workflow tailored to your work.

ChatGPT, which used to only answer questions, now works directly on my computer. I give it instructions in Korean without typing a single line of code and receive the results as files. This six-part series, including the orientation, explains Codex’s workflow of context, planning, execution, and deliverables, then covers everything from safely defining a working folder to organizing files, creating tables with sources, and setting up scheduled executions that run automatically at a specified time.

We will develop a mobile portrait-oriented idle RPG game from start to finish using Claude Code, Vite, TypeScript, and HTML5 Canvas. This is a practical web game development project that implements core game systems such as auto-battle, gacha systems, and equipment enhancement step-by-step, with the goal of being ready for a future Google Play Store release.

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.

The time when your imagination becomes reality—welcome to the world of 'Vibe Coding.' We prepared this course for those of you who may not know coding but know exactly what you want to create. With the emergence of AI tools like ChatGPT and Claude, people say that anyone can develop software. But what happens when you actually try? - "It writes simple code well, but once the number of files increases, the AI forgets what came before." - "It looks plausible, but when I run it, errors occur—and when I ask it to fix them, it gives me even more unrelated code." You’ve probably had experiences like these at least once. I experienced the same frustrations when I first started collaborating with AI. AI was an excellent 'assistant,' but it had limitations because it couldn’t see the entire forest. However, after discovering OpenAI Codex CLI and learning a new approach called 'Vibe Coding,' my development process completely changed. This course will solve the problems you’re experiencing while transforming you from someone who isn’t a coder into a director who commands AI agents. Equip yourself with the powerful tool Codex CLI, and join me on the exhilarating journey of Vibe Coding, where imagination becomes reality.

I’ll show you, through an actual work session building a to-do page from scratch, the process of requesting, checking, and revising that I refined after using more than 58.3 billion tokens with Codex. You’ll learn how to ask for the results you want without knowing all the code and how to directly verify the changes.

Learn how to efficiently manage multiple AI coding agents, including Claude Code, Codex, and pi, from a single screen. Starting with tmux concepts, you’ll practice using Herdr’s sessions, panes, plugins, and CLI to build an agent workflow that keeps your work running even when your SSH connection is interrupted. Complete the essential development environment for the Agent era in just one day.

If you keep getting errors after asking AI to do it, the problem isn’t the AI—it’s that you lack the foundational knowledge to guide it. In this video, we’ll cover the seven foundational concepts that people who get stuck while vibe coding were missing, and explain what each one is and why it’s necessary. 👾 This is explained for people on day zero of coding who have never opened a terminal before.

"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
