How do I rotate an object while the key is pressed?

Question

Here's my code:

public Transform Dummy;
public Transform Sphere;


void Start () {
    Sphere.SetParent(Dummy);
}

// Update is called once per frame
void Update () {
    if (Input.GetKeyDown(KeyCode.Space))
        Dummy.rotation = Quaternion.RotateTowards(transform.rotation, new Quaternion(1, 1, 1, 0), (float)20 * Time.deltaTime);
}

The problem is that it rotates only once when the Space key is pressed, so I need to press it many times, which is bad. I need to rotate the Dummy while the space key is pressed.

如果要连续旋转，则应使用GetKey ，而不要使用GetKeyDown 。
