Is millis() heavy on CPU program efficiency?

[glv]

Hello,

I can’t comment on efficiency…

In Processing I have used frameCount:

Animation that transitions using frameCount

A very simple example that transitions through scenes over time: // Author: GLV // Date: 2019-11-10 // Description: // Animate over time using frameCount // A very simple example that: // Uses frameCount to keep track of time // Fades in and out by modifying alpha component of HSB color // Cycles through HSB colors int scene = 0; int sec = 60; float alpha = 0; void setup() { size(500, 500); textSize(36); textAlign(CENTER, CENTER); colorMode(HSB, 360, 100, 100, 100); } void draw()…

I do not know how stable the frameRate is using P5.js on an Android.
Your mileage may vary depending on what you’re sketch is doing; I often monitor frameRate to see if sketch is slowing things down and work to optimize code.
