SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies complex animation logic by providing a suite of powerful utility functions for data manipulation, math operations, and common animation tasks, making your GSAP code cleaner and more efficient.

Core Features & Use Cases

  • Math & Data Helpers: Utilize functions like clamp, mapRange, normalize, random, wrap, interpolate, and pipe for precise control over values.
  • Array & Selector Utilities: Easily convert array-likes with toArray, distribute values with distribute, or create scoped selectors with selector.
  • Unit Manipulation: Extract units with getUnit or add them with unitize.
  • Use Case: Dynamically adjust animation properties based on scroll position, mouse movement, or other real-time inputs with functions like mapRange and clamp.

Quick Start

Use the gsap-utilities skill to map a scroll progress value between 0 and 1 to an x-translation between 0 and 500 pixels.

Frequently Asked Questions about gsap-utilities

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

FAQPage Schema
How do I map a scroll progress value to an animation property in GSAP?

To map a scroll progress value in GSAP, use the `mapRange` utility function to translate a normalized 0-1 input range into a specific output range like 0-500 pixels for x-translation. This provides precise dynamic value control.

What is the best way to constrain animation values within a specific range using GSAP utilities?

The best way to constrain animation values in GSAP is using the `clamp` utility function, which restricts a given number to a specified minimum and maximum range. This prevents properties from exceeding desired visual boundaries during dynamic updates.

Can I chain multiple mathematical operations together in a GSAP animation sequence?

Yes, you can chain multiple mathematical operations in GSAP using the `pipe` utility function. `pipe` passes the result of one function directly into the next, enabling complex data transformations and efficient function chaining for animation sequences.

How do I convert array-like objects into standard arrays for GSAP selectors?

To convert array-like objects into standard arrays for GSAP, use the `toArray` utility function. This simplifies array manipulations by allowing you to distribute values evenly or iterate over elements using standard array methods.

Does GSAP provide utilities for extracting and adding units to animation values?

Yes, GSAP provides the `getUnit` utility function to extract units from string values and the `unitize` function to append units to numerical values. This facilitates precise unit manipulation and dynamic property adjustments.

When do I need utility functions for random value generation in GSAP projects?

You need the `random` utility function in GSAP projects when generating dynamic animations requiring unpredictable values. It addresses the need for efficient coding and precise control by producing random numbers within a defined range.
