How to Build Dynamic Particle System in Rive Using Scripting & AI Agent
*Want the source files? I put them all in one place with a cheat sheet → rivemasterclass.com/scripting
In this tutorial, I walk through how to build a fully dynamic particle system in Rive using the new scripting feature and the Rive AI Agent.
The example is a Christmas snow effect, but the goal isn’t the snow itself —
it’s learning how to think about particles as a system:
• one script
• reusable logic
• full control over count, speed, wind, scale, and parallax
• no keyframes for the particles
Throughout the video, I build the system step by step,
using the AI Agent to iterate on the logic and keep the code clean and flexible.
The same approach can be remixed into rain, confetti, dust,
or any custom particle-based effect.
