Movement speed is being affected by the frame rate despite using Time.deltaTime.

Unity Engine
1 
    //Movement
    var walk : float = Input.GetAxis ("Vertical") * walkSpeed;
 
    if (Input.GetKey (KeyCode.W)) {
        rigidbody.MovePosition (transform.position + transform.right * walk * -1 * Time.deltaTime);
    }
    if (Input.GetKey (KeyCode.S)) {
        rigidbody.MovePosition (transform.position + transform.right * walk * -1 * Time.deltaTime);
    }

What am I doing wrong? Thanks in advance.

Update or FixedUpdate?

Update

What happens if you change the + into - and remove that “-1”?

I tend to put parenthesis around the ‘-’ on those calculations, to be really sure that it does not interpret it as a subtraction.

Not saying it will change a thing, but it might.

Thanks for the tip but unfortunately you were right, it didn’t change anything.

Moving it to FixedUpdate solved the the problem. I used this code.

function FixedUpdate () {
    //Movement
    var walk : float = Input.GetAxis ("Vertical") * walkSpeed;
    if (walk > 0 || walk < 0) {
        rigidbody.MovePosition (transform.position - transform.right * walk * Time.deltaTime);
    }
}

Rigidbodies get updated on FixedUpdate. You register them to be updated in Update, tho they will carry the old position untill a FixedUpdate kicks in, updating the position to the one last set by an Update. Make sure to handle anything related to rigidbodies in FixedUpdate in the future.
