Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

Babel includes JSX processing.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Click Test - Measuring the Boundaries of a Circle

Click inside the circle to see the background color change!

Code by Anthony T. Marasco [2019]

let d, r; //declare our disatance and radius variables
let backColor = "gray";
let circX = 250;
let circY = 250;
let circDiam = 200; //diameter of the circle

function setup() {
  createCanvas(500, 500);
  r = circDiam / 2; //we can init this in setup() because this value will never change

function draw() {
  /* with every loop of the draw() block, we
need to recalculate the distance between the circle's
center and the mouse X & Y!

  d = dist(circX, circY, mouseX, mouseY);

  /*if the mouse is pressed AND if the result of the dist() function 
is less than the radius of the circle...  

  if (mouseIsPressed && d < r) {
    backColor = "pink";
  } else {
    backColor = "gray";

  ellipse(circX, circY, circDiam, circDiam);
