Pause / stop / `noLoop()` p5 sketch when not actively seen by the user (e.g. after scrolling out of window)

[GoToLoop]

Multiple sketches in instance mode

Indeed it is so. But we can try to mitigate some of it. If you have a sketch which just displays a static drawing you can call noLoop() to halt the sketch: p5js.org/reference/#/p5/noLoop 'use strict'; function setup() { createCanvas(500, 400); noLoop(); } Or if you have a sketch which only needs to update the canvas after a user input such as moving the mouse, besides using noLoop() you also call redraw() within the user input event callback: p5js.org/reference/#/p5/redraw p5js.org/…
