The accelerationX system variable is responsible for the acceleration of the device(tablets or mobile phones) along the x-axis. It can be used with the draw() function to accelerate the device in the x-axis of the coordinate.
Its value is represented as meters per second squared.
Syntax:
accelerationX
Example 1:
Javascript
// Move a touchscreen device to register // Acceleration changes. function setup()
{ createCanvas(400,400)
} function draw() {
background(0, 50);
fill( 'green' );
textAlign(CENTER,CENTER);
textSize(50);
// Convert the acceleration into integer when
// device is moved along x axis.
text(int(accelerationX),windowWidth/2,windowHeight/2);
} |
Output:
Example 2:
Javascript
// Move a touchscreen device to register // Acceleration changes. function draw() {
createCanvas(400,400);
background(220);
fill( 'green' );
// Set the variable.
ellipse(width / 4, height / 4, accelerationX);
} |
