The mouseX variable in p5.js is used to store the current horizontal position of the mouse, relative to (0, 0) of the canvas. If touch is used instead of mouse input, mouseX will hold the x value of the most recent touch point.

Syntax:

mouseX

Below programs illustrate the mouseX variable in p5.js:

Example 1: This example uses mouseX variable to display position.




function setup() {
      
    // Create canvas
    createCanvas(1000, 400);
      
    // Set the text size

}
   
function draw() {
      
    // Set background color
    background(200);
      
    // Create rectangle
    rect(mouseX, height/2, 30, 30);
      
    // Display position
    text("Position of mouse relative to canvas is "
            + mouseX, 30, 40);
