Developer Builds 3D Browser Game Using Claude Code Opus and Three.js
Project Overview
A developer built Traffic Architect, a 3D road building and traffic management game that runs entirely in browser. The game is available at crazygames.com/game/traffic-architect-tic.
The technical stack consists of Claude Code Opus 4.6 and Three.js. The entire project was code-generated with no external image files, 3D models, or sprite sheets. Claude Code writes JavaScript that creates all visuals at runtime.
Game Mechanics
In Traffic Architect, players design road networks for a growing city. Buildings spawn and generate cars that need to reach other buildings. Players connect buildings with roads, earn money from deliveries, and unlock new road types. The game ends if traffic backs up.
Claude Code Workflow Strategies
The developer shared specific strategies for working effectively with Claude Code:
- Planning first: Always start by making a plan before writing any code. Break work down into small, focused tasks - one thing at a time. This keeps Claude from going off track or trying to do too much at once.
- Review everything: Review every code change Claude produces. Don't just accept and move on. If something doesn't look right or there's a better approach, push back and iterate until satisfied with the solution.
- Small tasks, not big ones: Keep tasks small and specific. Vague or massive tasks tend to cause Claude to drift. Small, well-defined tasks provide more control over the output.
- Collaborative approach: Some optimizations came from the developer, some Claude suggested. The key is evaluating everything critically - Claude proposes, the developer reviews, and they go back and forth. The relationship is described as "more like working with a junior developer than hitting auto-pilot."
- Stay hands-on: Claude Code works best when staying in the loop. The cycle of pre-plan, decompose, review, and iterate keeps quality high.
The developer is open to questions about the Claude Code workflow and welcomes honest feedback on the game.
