p5.js accelerationY variable

The accelerationY system variable is responsible for the acceleration of the device(tablets or mobile phones) along the y-axis. It can be used with the draw() function to accelerate the device in the y-axis of the coordinate system.

Its Value is represented as meters per second squared.

Syntax:

accelerationY

Example 1:

Javascript

// Move a touchscreen device to register
// Acceleration changes.
function setup()
{
  createCanvas(400,400)
}

function draw() {
  background(270);

  fill('red');
  textAlign(CENTER,CENTER);
  textSize(50);
  // Convert the acceleration into integer when
  // Device is moved along y-axis.
  text(int(accelerationY),windowWidth/2,windowHeight/2);
}

Output:

Example 2:

Javascript

// Move a touchscreen device to register
// acceleration changes.
function draw() {
  createCanvas(400,400);
  background(220);
  fill('blue');

  //Set the variable.
  square(width/2, height/2, accelerationY);
}

Output:
