Description

Increasing access

If I call const myMouse = uniformVec2(() => mouseX), I get TypeError: data.slice is not a function.

This would be a lot clearer if it said that uniformVec2 expects an array with 2 items.

Most appropriate sub-area of p5.js?
  • Accessibility
  • Color
  • Core/Environment/Rendering
  • Data
  • DOM
  • Events
  • Image
  • IO
  • Math
  • Typography
  • Utilities
  • WebGL
  • Build process
  • Unit testing
  • Internationalization
  • Friendly errors
  • Other (specify if possible)
Feature enhancement details

There are existing internal error loggers for p5.strands that this should be using.
