SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires gsap, and includes scripts (resource) components.

What problem does it solve?

This Skill provides a suite of utility functions for GSAP, helping developers implement complex animations and transformations with ease.

Core Features & Use Cases

  • Math and Array Handling: Utilize functions like clamp, mapRange, and normalize for precise value transformations.
  • Randomization: Randomize values or pick elements from arrays with random and shuffle.
  • Snap and Wrap: Implement grid-aligned and cyclic values with snap and wrapYoyo.
  • Color Parsing: Extract units and parse color strings with getUnit and splitColor.
  • Collections and Arrays: Work with arrays and collections through selector, toArray, and pipe.
  • Use Case: Enhance a GSAP animation by using gsap.utils.mapRange to map scroll position to a value range, and then gsap.utils.snap to snap the value to a grid.

Quick Start

Use the gsap-utils skill to apply a snap function to an element's position with the command: snap(10, 20, element).

Frequently Asked Questions about gsap-utils

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

FAQPage Schema
How do I map scroll position to an animation value range using GSAP?

To map scroll position to an animation value range using GSAP, you can use the `mapRange` utility function to transform a progress value into a specific output range. This allows precise value manipulation for scroll-linked animations and transformations.

What is the best way to randomize array elements for GSAP animations?

The best way to randomize array elements for GSAP animations is using the `random` and `shuffle` utility functions. These functions allow you to randomize values or pick elements from arrays directly within GSAP's UtilityMethods.

Can I snap animated values to a grid using GSAP utility functions?

Yes, you can snap animated values to a grid using GSAP utility functions. The `snap` function implements grid-aligned values, allowing you to constrain element positions to specific intervals, such as using `snap(10, 20, element)`.

Does GSAP provide utility functions for normalizing and clamping values?

GSAP does provide utility functions for normalizing and clamping values. Within its UtilityMethods, you can use `clamp` to restrict values to a range and `normalize` to map values to a 0-1 scale for precise value manipulation.

How do I handle cyclic animations with GSAP utility functions?

To handle cyclic animations with GSAP utility functions, you can use the `wrap` and `wrapYoyo` functions. These utilities implement cyclic values, ensuring that animated numbers or positions loop seamlessly back to their starting points.

Do I need the GSAP library installed to use these utility functions?

You need the GSAP library installed to use these utility functions. The suite requires GSAP as a dependency for execution, as it directly supports GSAP's UtilityMethods for math, randomization, and array handling operations.
