Rotating an Object on Key Press!

Question

Hello, I am new to JavaScript but I would like to know how to rotate an object on its X axis using the A-key (rotate left) and the D-key (rotate right).

Can anyone please input a working JavaScript code that will allow an object to rotate using these keys?

Much appreciated!

Here is a quick script. Attach it to any object. Note it rotates around Y axis (since you mentioned left and right). If you really want the X axis, replace Vector3.up with Vector3.right.

var speed = 30;

 function Update () {
 
  if (Input.GetKey(KeyCode.A))
      transform.Rotate(Vector3.up * speed * Time.deltaTime);
      
  if (Input.GetKey(KeyCode.D))
      transform.Rotate(-Vector3.up * speed * Time.deltaTime);
 
 }

correct script:

 #pragma strict
 
 var velocidade = 30;
 
 function Start () {
 
 }
 
 function Update () {
 
     if (Input.GetKey(KeyCode.A)){
       transform.Rotate(Vector3.up * velocidade * Time.deltaTime);
       
     }
       
     if (Input.GetKey(KeyCode.D)){
       transform.Rotate(-Vector3.up * velocidade * Time.deltaTime);
  
     }
 
 }

@SparkDev be sure that you created JavaScript and no C# also be sure that JavaScript is not longer supported in newer versions of Unity

Replace 'Function' with 'Void'
