Help with Controlled orbiting

Unity Engine
1

My first post, so sorry if formatting is incorrect.
So I want to simulate tilt controls via the analog stick, and have the object in question sort of rotate around another. I tried Transform.RotateAround, but that’s a continual adding, which removes control
I also tried EulerAngles and saw my angle can be made to directly tie to the stick angle, but I’m not orbiting around the other object at all. Can someone help?
In other words, I just want to pivot around another GameObject, temporarily so no childing/parenting
My code:

public class Tilt : MonoBehaviour {
    public GameObject parentee;
    private Vector3 originalpos;
    private Quaternion originalrot;
    private Vector3 rotater;
    public float timetoget;
    float tx;
    float tz;
    // Use this for initialization
    void Start () {
        parentee = GameObject.FindGameObjectWithTag("Rotatee");
        originalpos = this.transform.position;
        originalrot = this.transform.rotation;
    }

    // Update is called once per frame
    void FixedUpdate() {

        Vector3 bobp;
        bobp = this.transform.position;
        Quaternion bobr;
        bobr = this.transform.rotation;
        //Debug.Log (this.transform.rotation.x);

        float newHeadingx = Input.GetAxis("Vertical");
        float newHeadingz = Input.GetAxis("Horizontal");

        rotater.Set(parentee.transform.position.x, parentee.transform.position.y, parentee.transform.position.z);
        if (Input.GetAxis("Vertical") != 0.1f || Input.GetAxis("Horizontal") != 0.1f)
        {
            if (0.19797f >= Mathf.Abs(this.transform.rotation.x) || 0.19797f >= Mathf.Abs(this.transform.rotation.z)) {
                //transform.RotateAround(rotater, Vector3.right, 20 * Time.deltaTime * Input.GetAxis("Vertical"));
                this.transform.eulerAngles = new Vector3((newHeadingx * 23f), 0, (newHeadingz * -23f));
                tx = 0f;
                }
            }
            if (Input.GetAxis("Vertical") == 0f && Input.GetAxis("Horizontal") == 0)
            {
            tx = 0.2f;
                this.transform.position = Vector3.Lerp(bobp, originalpos, tx);
                this.transform.rotation = Quaternion.Lerp(bobr, originalrot, tx);
            }
        }
    }

I would just make a temp object where you want to pivot, parent to that object, rotate the temp object, deparent, and destroy the temp object.

You could also cache the temp object and keep it around for reuse if you’re using it every frame. Just move it where you want to pivot, parent, pivot, then deparent.

Hmm, I want the radius to update though if the “parent” moves closer/farther though

Wouldn’t it already? If you exist in an unparented state normally, then:

  • move the parent pivot where you want (i.e., set the radius)
  • parent
  • rotate
  • deparent

Isn’t it just done?

Try it by hand in the editor if you doubt me. Nothing could be easier to test in the editor than that!!
