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); } |
