Static p5_sys::global::touchStarted

pub static touchStarted: TouchStartedInternalType

The touchStarted() function is called once after every time a touch is registered. If no touchStarted() function is defined, the mousePressed() function will be called instead if it is defined.

Browsers may have different default behaviors attached to various touch events. To prevent any default behavior for this event, add "return false" to the end of the method.

Examples

// Touch within the image to change
// the value of the rectangle

let value = 0;
function draw() {
  fill(value);
  rect(25, 25, 50, 50);
}
function touchStarted() {
  if (value === 0) {
    value = 255;
  } else {
    value = 0;
  }
}

function touchStarted() {
  ellipse(mouseX, mouseY, 5, 5);
  // prevent default
  return false;
}

// returns a TouchEvent object
// as a callback argument
function touchStarted(event) {
  console.log(event);
}

Parameters

event? optional TouchEvent callback argument.
