Springy FX is a toolset for Adobe After Effects designed to automate secondary motion—like elastic bounces, jiggles, and overlaps—without complex manual keyframing. Version 1.0 focuses on nine primary tools that react to your layer's existing position and scale animations. 1. Installation & Setup
To use Springy FX, you must first enable script permissions in After Effects:
Enable Scripting: Go to Edit > Preferences > General (Windows) or After Effects > Preferences > General (Mac) and check Allow Scripts to Write Files and Access Network. Placement: Springy FX v1.0

Springy FX v1.0 is an After Effects extension by Fremox designed to automate secondary motion—such as jiggling, overlapping, and "squash and stretch"—based on existing keyframed transform properties. The toolset includes nine distinct tools, such as Parent Constraint, Bend, and Liquid, which allow for customizable physics control through a dedicated "Spring Constraint CTRL" layer.

Jargon: The higher the stiffness, the faster the return to equilibrium. In practice: A stiffness of "0" feels like cold honey; a stiffness of "100" feels like a tennis ball.
Before proceeding, understand that Springy FX v1.0 typically utilizes a Martingale or Grid strategy.
npm install springy-fx
import Spring from 'springy-fx';
const s = new Spring( stiffness: 150, damping: 12 );
s.to(1); // animate value to 1
s.onUpdate(v => element.style.transform = `translateX($v*100px)`);
