Help with refining rotation deciphering the switch and drag. This is for touch and C#.

Hey All!

First post here. I am creating a jar object and just like in real life you can rotate /spin the jar with your hands and stop it in place. This code works but I am having trouble making it look fluid and nice. I can clearly see the the switch between running switch and drag because it has a very hard stop once the distance was far enough. Any sense of direction or approach is greatly appreciated! I am a sponge and want to learn everything! Here is my pseudocode:

Pseudo

FixedUpdate()

• addTorque to the rotation

For each touch:

TouchDown

• Freeze the rotation. // when the finger is on the jar object, the object should stop rotating.

• Initialize the touch. // needs to referenced to measure swipe.

TouchMove

• if (swipe distance is greater than minimum swipe) // If swipe distance is greater than minimum swipe which is currently a test number. -----> then it is considered a swipe. Jar will rotate + the addTorque and to slow down rotation.

• else ------> track the finger position and direction to drag and rotate the object.

TouchUp

• Un-freeze the rotation

• The touch from TouchDown is now a new Touch()

  My Actual Code

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class ButtonCube : MonoBehaviour {

 private Touch initialTouch = new Touch();
 private float rotationRate = 5.0f;
 private float amount = 5.0f;
 private float torque = 3.0f;
 public Rigidbody jar;
 private float getXAxis;
 private float distance;
 private bool hasSwiped = false;
 public Vector3 eulerAngleVelocity;
     
  void FixedUpdate() {
     if (Input.touchCount > 0) {
         getXAxis = Input.touches[0].deltaPosition.x;
     }
     float h = getXAxis * amount * Time.deltaTime;
     jar.AddTorque(transform.up * torque * -h);

     foreach (Touch touch in Input.touches) {
         Debug.Log ("Touching at: " + touch.position);
         if (touch.phase == TouchPhase.Began) {
             Debug.Log ("Freeze");
             jar.freezeRotation = true;
             initialTouch = touch;
         } 
         else if (touch.phase == TouchPhase.Moved && !hasSwiped) {
             Debug.Log ("Touch phase Moved");
             float deltaX = initialTouch.position.x - touch.position.x;
             distance = Mathf.Sqrt(Mathf.Pow(deltaX, 2));
             if (distance > 50f) { // this is where I need HELP the most!
                 Quaternion deltaRotation = Quaternion.Euler (eulerAngleVelocity * Time.deltaTime);
                 jar.MoveRotation (jar.rotation * deltaRotation);
                 hasSwiped = true;
             } else {
                 jar.transform.Rotate (0 * rotationRate, -touch.deltaPosition.x * rotationRate, 0, Space.World);
             }

             }
         else if (touch.phase == TouchPhase.Ended) {
             Debug.Log ("Touch phase Ended" + "UnFreeze"); 
             jar.freezeRotation = false;
             initialTouch = new Touch();
             hasSwiped = false;
         }
     }
 }        

}

Thank you in advance! I am excited to hear your feedback.
