Hello Forum, I am working a project running p5js sketches from Open Processing on mobile devices. I have the need to create a series of timed events with millis() but this slowing things down greatly! Are there efficient strategies for multiple events timed that are better than millis()? Thanks fo…

Hi GoToLoop - first thank you! I have been playing with your ideas and testing some others from other code friends too. In the end, I found a solution with setInterval() which worked best for my particular project. Here’s a reduced version of how it works for me: 'use strict'; var button; let t…

Hello, I can’t comment on efficiency… In Processing I have used frameCount: [image] Animation that transitions using frameCount Gallery A very simple example that transitions through scenes over time: // Author: GLV // Date: 2019-11-10 // Description: // Animate over t…

I found this interesting enough to test, and you are right; using millis() in a loop drove my CPU use up to a level of 55%! Using frameCount (as glv suggested), in a loop , does not give significant alternation.

The frameCount approach is very light but is bound by the frameRate(): p5js.org/reference/#/p5/frameRate Another good performant approach is setTimeout(): [image] WindowOrWorkerGlobalScope.setTimeout() The setTimeout() method of the WindowOrWorkerGlobalScope mixin (and successor to Win…

@GoToLoop Thanks for pointing me out to the java timer utilities. The most concise code I could make is this one. import java.util.Timer; import java.util.TimerTask; void setup() { size(500, 500); background(255); Timer timer = new Timer(); TimerTask task = new TimerTask() { public …

[image] mnoble: Is this something I could use on OpenProcessing with p5Js to solve this problem: There are at least 3 ways to tackle that: Use p5js’ own millis() . Use JS’ setTimeout() . Use my Countdown class, which is a wrapper for setTimeout() btW. If you decide to pick my “library” class…

Is millis() heavy on CPU program efficiency?
