Fly System

Inspiration

We wanted to create a flight system that is not only fun to use but also fully remixable—something any creator can copy, modify, and extend in their own projects. That’s why we set out to build a version that feels smooth, immersive, and completely open.

What it does

Fly System is a physics-based, modular flight toolkit for Horizon Worlds. It features gravity and inertia simulation, responsive camera control, and immersive feedback such as wind sounds, glide audio, trails, and particles. All flight parameters (speed, gravity strength, resistance, etc.) are fully configurable, giving creators complete control.

How we built it

We combined a physics-driven flight simulation with modular design principles. Controls, camera, audio, and effects were developed as independent, remixable components. This allows creators to copy the world, tweak parameters, or swap assets to quickly build unique flight experiences.

Challenges we ran into

The main challenge was balancing realism and fun. Too much realism made the system difficult to control, while oversimplification made it feel weightless. We also had to ensure the system was modular enough so that remixing wouldn’t break core functionality.

Accomplishments that we're proud of

We built a flight experience that feels both natural and customizable. More importantly, it serves as a ready-to-use toolkit, empowering other creators to design their own flight mechanics with ease.

What we learned

We learned the importance of modular design for remixable projects. By decoupling physics, visuals, audio, and camera systems, the toolkit became far easier to expand and maintain.

What's next for Fly System

We plan to add advanced features such as boost/dash mechanics, energy management, and multiplayer compatibility. We’ll also provide more presets and templates so creators can remix and apply Fly System into their own worlds instantly.
