@fxdff,

I can change values on OpenProcessing and see changes to running sketch.

I downloaded the sketch and can run it on a local [web server](https://chrome.google.com/webstore/detail/web-server-for-chrome/ofhbbkphhbklhfoeikjpcbhemlocgigb/) and can see changes.

It also works with Processing PDE in P5.s mode.

One of the variables I changed was:  
`var maxSpeed = 3.0; //Changes to 1.0`

Take a look here:  
_[get started | p5.js](https://p5js.org/get-started/)_ It has a link to running a local server.
