touches

An Array of all the current touch points on a touchscreen device.

The touches array is empty by default. When the user touches their screen, a new touch point is tracked and added to the array. Touch points are Objects with the following properties:

// Iterate over the touches array.
for (let touch of touches) {
  // x-coordinate relative to the top-left
  // corner of the canvas.
  console.log(touch.x);

  // y-coordinate relative to the top-left
  // corner of the canvas.
  console.log(touch.y);

  // x-coordinate relative to the top-left
  // corner of the browser.
  console.log(touch.winX);

  // y-coordinate relative to the top-left
  // corner of the browser.
  console.log(touch.winY);

  // ID number
  console.log(touch.id);
