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); } |
Output:
