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:
