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:
// 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:
// 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:
