p5.js turnAxis variable

The turnAxis variable is used to store the axis triggered by the deviceTurned() method. This takes place when a mobile device is rotated in any of the X, Y or Z axis. This variable is only defined within the scope of the deviceTurned() function.

Syntax:

turnAxis

The below example demonstrates the turnAxis variable in p5.js:

Example:

Javascript

// Define a variable that will hold
// the background color
var value = 0;

function setup() {
    createCanvas(windowWidth, windowHeight);

    // Set the background as the variable
    background(value);
}

// Define the draw function
function draw() {

    // Set the properties of text
    background(value);
    fill(0, 0, 255);
    textAlign(CENTER, CENTER);
    textSize(25);

    // Set the limit for value
    // When the value is greater than 10
    if (value === 0) {
      text("Device is Relaxed ",
      width / 2, height / 2);
    } else {
      text("Device is moved in X- axis",
      width / 2, height / 2);
    }
}

// Set the value depending on the turnAxis
function deviceTurned() {

    if (turnAxis === 'X') {

      // Constrain the value so that
      // it can be used as the background
      // color
      value = constrain(value + 50, 0, 255)
    }
}
