Vibe Coding: Build Your Dream Game with AI (Even If You Can't Code!)

Want to create your own video game, but feel overwhelmed by complex coding? Enter vibe coding, a revolutionary approach that leverages the power of AI to bring your game ideas to life—even if you're not a seasoned programmer. This guide to vibe coding will get you building in no time.

What is Vibe Coding?

Vibe coding is a collaborative method where you guide AI tools like Grok 3 Thinking and Cursor with Claude Sonnet 3.7 Thinking to develop your game. You provide the vision and direction, while the AI handles the technical implementation. It's like having a super-powered coding partner who translates your ideas into a playable reality.

Ready to Start Vibe Coding? Essential Tools & Setup

Before diving in, you'll need a few key tools and a well-organized setup. Proper preparation is crucial for a smooth and efficient development process. Think of it as laying a strong foundation for your game.

• Grok 3 Thinking: This AI will be your strategist, helping with game design, tech stack selection, and implementation planning.
• Cursor with Claude Sonnet 3.7 Thinking: This is your coding assistant, executing the implementation plan and writing the actual game code.

Game Design First: Planning and Structure are Everything

Don't jump straight into coding! A well-defined plan is essential for preventing chaos and ensuring a manageable codebase.

• Create a Game Design Document (GDD): Use Grok 3 to generate a basic GDD in Markdown format. This document outlines your game's concept, mechanics, and features. Review and refine it to match your vision.
• Choose Your Tech Stack: Let Grok 3 suggest the best technologies for your game (e.g., ThreeJS and WebSocket for 3D multiplayer). Challenge it to propose the simplest, yet most robust stack.
• Craft an Implementation Plan: Provide Grok 3 with the GDD, tech stack, and Cursor rules, then ask it to create a detailed, step-by-step implementation plan in Markdown. Each step should include a test to validate the implementation. Focus on the core game mechanics first.

Organize Your Project: The "Memory Bank"

Think of your project directory as your AI's brain. A well-organized file structure helps Claude Sonnet 3.7 Thinking stay on track and understand the project's context.

• Create a folder in Cursor for your project.
• Inside, create another folder named "memory-bank."
• Add these files to the "memory-bank":
  • game-design-document.md
  • tech-stack.md
  • implementation-plan.md
  • progress.md (to track completed steps)
  • architecture.md (to document file purposes).

Setting the Rules: Guiding Your AI Developer

Establish clear guidelines for Cursor so it generates clean, optimized, and modular code. This sets the stage for a well-structured and maintainable game.

• Define Cursor Rules: Ask Grok 3 to write 6-10 rules for Cursor, acting as a senior game developer specializing in your chosen tech stack.
• Emphasize Modularity: Ensure one rule focuses on using multiple files to avoid a monolithic codebase.
• Input Rules into Cursor: Press Cmd + Shift + P in Cursor, type "rules," and enter the generated rules.

Time to Vibe Code! Implementing the Base Game

With your tools set up and plan in place, the real fun begins! You're about to start coding your game… without actually writing code yourself.

1. Clarify the Plan: In Cursor, with Claude Sonnet 3.7 Thinking selected, prompt: "Read all the documents in /memory-bank, is implementation-plan.md clear? What are your questions to make it 100% clear for you?" Answer the questions and ask Claude to edit the implementation plan accordingly for better clarity.
2. The First Implementation Prompt: Select Claude Sonnet 3.7 Thinking in Cursor and use this prompt: "Read all the documents in /memory-bank, and proceed with Step 1 of the implementation plan. I will run the tests. Do not start Step 2 until I validate the tests. Once I validate them, open progress.md and document what you did for future developers. Then add any architectural insights to architecture.md to explain what each file does."
3. Iterative Development: After completing Step 1, commit your changes to Git, then start a new "composer" in Cursor (Cmd + N, Cmd + I). Prompt: "Now go through all files in the memory-bank, read progress.md to understand prior work, and proceed with Step 2. Do not start Step 3 until I validate the test." Repeat this process until the entire implementation plan is complete.

From Base to Beautiful: Adding Details & Features

Once the base game is running, it's time to add the bells and whistles that will make it truly shine. Want fog, post-processing, effects, or a better game environment?

• Feature Implementation: For each major feature, create a new feature-implementation.md file with short, testable steps.
• Incremental Implementation: Implement and test each feature incrementally to avoid overwhelming the system.

Troubleshooting Like a Pro: Fixing Bugs and Getting Unstuck

Even with AI assistance, you'll inevitably encounter bugs or get stuck. Don't panic! Here's how to handle common issues:

• Failed Prompts: Click "restore" in Cursor and refine your prompt until it works.
• JavaScript Errors: Open the console (F12), copy the error, and paste it into Cursor or provide a screenshot. Consider using BrowserTools to streamline bug reporting.
• Getting Stuck: Revert to your last Git commit (git reset) and retry with new prompts.
• Desperate Times: Use RepoPrompt and ask Grok 3 Thinking for assistance.
