FlyHi – Realism 3D Flight Simulator

Overview

The vibe-coded flight simulator, developed by Melvin Vivas (@donvito), is an AI-assisted 3D flight simulation game built using pure prompting and modern AI tools. Hosted in the browser, the project gained significant attention on X for its rapid development and impressive realism. The simulator features an Emirates Airbus A345 navigating a scenic environment, including cliffs and a runway, and is accessible via https://flyhi.netlify.app.

Origins of the Project

The project originated from Vivas’s fascination with AI-driven game development. In this post, Vivas expressed amazement at creating a flight simulator—one of his favorite game types—using AI tools, spending an additional 6 hours on development after initial experimentation.

Success

The flight simulator quickly garnered viral attention on X, with users praising its realism.

How It Is Made

Vivas developed the simulator using “pure prompting” with AI tools, specifically Cursor AI (@cursor_ai), Anthropic’s Sonnet model (@Anthropic), and the Three.js JavaScript library (@threejs), as detailed in his initial post. The process involved minimal coding, relying on AI-generated code to create a browser-based 3D environment. Vivas clarified the use of Three.js in response to a query. The 3D models, such as the Rumkale Fortress and the Emirates Airbus, were sourced from external creators, with credits provided in a follow-up post.

Future Plans

While specific future plans are not explicitly detailed in the provided X posts, Vivas’s ongoing updates suggest continuous improvement. For instance, he released a “hot update” adding a cityscape feature and addressing technical issues like Singapore Air movement. He also mentioned investigating caching solutions for asset loading, as noted in response to user feedback. These updates indicate an intent to refine and expand the simulator, potentially incorporating more features or addressing known issues based on community feedback.
