Adding movement time to rotation

Questions & Answers
1

I’m very new to Unity, and wanted to know how to add movement time to this simple script instead of it being jerky.

public class Rotation : MonoBehaviour {

public float rotatespeed;

void Update () {

    //rotate on d press
    if (Input.GetKeyDown("d"))
        {
            transform.Rotate(Vector3.back * rotatespeed);
        }

    //rotate on d retract
    if (Input.GetKeyUp("d"))
    {
        transform.Rotate(Vector3.forward * rotatespeed);
    }

I would first make your rotation frame rate independent by multiplying the speed by deltaTime.

transform.Rotate(Vector3.back * rotatespeed  * Time.deltaTime);

If you are testing in the editor, I would try to run some tests with Maxiimize On Play enabled. A lot of stuttering happens just because of the editor overhead.

Food for thought, a lot of stuttering people see is the editor. It’s a weird beast. If you make an actual build of your app and run it on device, more than likely this type of stuttering goes away - with something as simple as this.
