Moving Camera with arrow keys only

Questions & Answers
1

So I have to create a mini game where the camera has to move with the arrow keys.
I have seen this post : Moving Camera with WASD - Questions & Answers - Unity Discussions

But the problem is I want the WASD keys for moving my player and the camera has to move independently so the examples presented there are not working for me.
If for example I use the code presented there :

void Update () {

    inputX = Input.GetAxis ("Horizontal");
    inputZ = Input.GetAxis ("Vertical");
     
    if (inputX != 0)
    {
        rotate ();
    }
        
    if (inputZ != 0)
    {
        move ();
    }

}

void rotate()
{
    transform.Rotate (new Vector3 (0f, inputX * Time.deltaTime, 0f));
}

void move()
{
    transform.position += transform.forward * inputZ * Time.deltaTime;
}

Then the camera moves fine with the arrow keys but also moves when using WASD.
Since I’m very new to Unity and C# any help will be much appreciated.

If you go to Edit > Project Settings > Input Manager, you will see that the Horizontal and Vertical movements have values set for “Negative Button” and “Positive Button”. In each case, they use the arrow keys. If you delete those entries (left, right, down, up), you will be left with just the WASD keys for these movements.

You will then need to use if (Input.GetKey(KeyCode.RightArrow)) etc to control the camera.
