Camera movement script not working properly

Unity Engine
1 
{
    public Transform target;

    public float height = 7;

    public float radius = 7;

    public float angle = 0;
    public float rotationalSpeed = 1;
   
    void Update ()
    {
        float cameraX = target.position.x + (radius * Mathf.Cos(angle));
        float cameraY = target.position.y + height;
        float cameraZ = target.position.z + (radius * Mathf.Sin(angle));

        transform.position = new Vector3(cameraX, cameraY, cameraZ);

        if(Input.GetKey(KeyCode.A))
        {
            angle = angle - rotationalSpeed + Time.deltaTime;
        }
        else if(Input.GetKey(KeyCode.D))
        {
            angle = angle + rotationalSpeed + Time.deltaTime;
        }

        transform.LookAt(target.position);
    }
}

This is the script I am working with but there are a few small issues with it.

1.) For some reason if the rotate speed is set to 1 and I press the key to turn the camera it moves extremely fast and far, the transition is not smooth at all. In fact its only about as smooth as I want it if I set the speed down to 0.05 which doesn’t seem right to me. Am I doing something wrong?

2.) when using the A key to rotate the camera it moves at one speed, but when I use the D key it moves at a much faster speed, about twice as fast or more. As far as I can tell this shouldn’t happen but it is, no clue why.

3.) if I want to change the keys for A and D to the arrow keys, what code do I use?

Any help at all on these issues would be great! Thanks

You are adding the time, p=vt, multiplying should take care of 1 and 2. As for 3, in Visual Studio you can get a list of everything ‘under the dot’ by deleting the .A after KeyCode temporarily and pressing the period key. You should see a list of options popup.

I am assuming I am switching line:
angle = angle - rotationalSpeed +Time.deltaTime;

ah ok handy, did not know that. I knew it was something simple haha. Thanks a bunch!

Both worked like a charm! Thanks a ton!
