p5.js Touch touchEnded()

Last Updated : 18 Aug, 2023
The touchEnded() function in p5.js is called when a touch ends. If no touchEnded() function is defined, the mouseReleased() function will be called instead if it is defined. Syntax: 
touchEnded([Event])
Below program illustrates the touchEnded() function in p5.js: Example-1: javascript 
let valueX;
let valueY;

function setup() {
  
    // Create Canvas of size 500*500
    createCanvas(500, 500);
}

function draw() {
  
    // set background color
    background(200);
  
    fill('green');
    // set text and text size
  
    textSize(25);
    text('Touch to change color', 30, 30);
    // fill color according to touchEnded() 
    fill(valueX, 255 - valueY, 255 - valueX);
    // draw ellipse  
    ellipse(mouseX, mouseY, 115, 115);

}

function touchEnded() {
    valueX = mouseX % 255;
    valueY = mouseY % 255;
}
Output: Example-2: javascript 
let valueX;
let valueY;

function setup() {
    // Create Canvas of size 500*500
    createCanvas(500, 500);
}

function draw() {
    // set background color
    background(200);
  
    fill('green');
    // set text and text size
    textSize(25);
  
    text('Touch and Move to change color', 30, 30);
    // fill color according to touchEnded() 
  
    fill(valueX, 255 - valueY, 255 - valueX);
    // draw rectangle 
  
    rect(mouseX, mouseY, 115, 115);
    fill(valueY, 255 - valueX, 255 - valueX);

    rect(mouseX, mouseY + 115, 115, 115);
    fill(255 - valueY, 255 - valueX, 255 - valueY);

    rect(mouseX - 115, mouseY, 115, 115);
    fill(255 - valueY, 255 - valueY, 255 - valueY);

    rect(mouseX - 115, mouseY + 115, 115, 115);
}

function touchEnded() {
    valueX = mouseX % 255;
    valueY = mouseY % 255;
}
