SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developers building GSAP-powered animations often need quick, reliable helpers to manage numeric transforms, array handling, and value mapping without rewriting boilerplate code.

Core Features & Use Cases

  • Provides clamp, mapRange, normalize, interpolate, random, snap, toArray, wrap, and pipe utilities for GSAP.
  • Use in ScrollTrigger callbacks, timelines, and per-frame calculations to simplify complex animations.
  • Example: clamp a value to a range, map a progress value to an animation range, and snap outputs to grid steps.

Quick Start

Use gsap.utils.clamp to constrain values within a range in your animation loop.

Frequently Asked Questions about gsap-utils

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I use GSAP utility helpers for animation math like clamping and interpolation?▼

GSAP utility helpers for animation math provide functions like clamp, mapRange, normalize, and interpolate to manage numeric transforms in GSAP-powered animations. They simplify complex value mapping without rewriting boilerplate code.

Can I use gsap.utils methods inside ScrollTrigger callbacks and timelines?▼

Yes, gsap.utils methods work within ScrollTrigger callbacks, timelines, and per-frame calculations. They support function form usage and operate without requiring external setup in codebases using GSAP.

What is the best way to map a progress value to an animation range in GSAP?▼

The best way to map a progress value to an animation range in GSAP is using the mapRange utility helper. It transforms normalized progress values into specific animation ranges, simplifying complex value mapping in animation loops.

Do I need external dependencies to use GSAP utilities for snapping and array handling?▼

No external dependencies are required to use GSAP utilities for snapping and array handling. The helpers include snap, toArray, and wrap utilities that satisfy the API usage of gsap.utils methods directly within your existing GSAP setup.

Why does my GSAP animation math require boilerplate code for value normalization?▼

GSAP animation math requires boilerplate code for value normalization without utility helpers. Using the normalize and pipe utilities eliminates this, allowing clean numeric transforms and value mapping directly in per-frame calculations.
