How to move the camera while holding down any key?

Question

C++ / C#

Here's what I got

private void Update() {
        pos = player.position;
        pos.z = -10f;
        transform.position = Vector3.Lerp(transform.position, pos, Time.deltaTime);
        if (Input.GetKey(KeyCode.S)) {
            bias = new Vector3(pos.x, pos.y - 5);
            transform.position = Vector3.Lerp(transform.position, bias, Time.deltaTime);
        }
    }

It is only necessary that the camera does not constantly mix by 5 units, but moves once and that's it

Answer 1

You can use Input.GetKeyDown("s"), this function is called only once when the button is clicked. Or it is possible to cut off some bool flag thread.
