Bug Moving UI elements over time produces bug.

Hi, I have a button that is moved with the code below, but it randomly sometimes gets stuck without reaching the target, any ideas would be much appreciated.

Code (CSharp):

1.     public RectTransform buttonsRT; // button RT used to move it.
2.     public RectTransform targetPosOneRect; // empty gameobject on the canvas that is used as a target.
3.     public RectTransform targetPosTwoRect;
4.  
5.     public void Execute()
6.     {
7.         StartCoroutine(PlayButtonCoroutine(targetPosOneRect.position, targetPosTwoRect.position, 750.0f, 1000.0f)); // Button pressed
8.     }
9.  
10.     private IEnumerator PlayButtonCoroutine(Vector3 posOne, Vector3 posTwo, float speedOne, float speedTwo)
11.     {
12.         yield return MoveRectTransformToTarget(buttonsRT, posOne, speedTwo);
13.         yield return MoveRectTransformToTarget(buttonsRT, posTwo, speedTwo);
14.     }
15.  
16.     private IEnumerator MoveRectTransformToTarget(RectTransform objectToMove, Vector3 posTarget, float speed)
17.     {
18.         while (objectToMove.transform.position != posTarget)
19.         {
20.             objectToMove.transform.position = Vector3.MoveTowards(objectToMove.transform.position, posTarget, speed * Time.deltaTime);
21.             yield return null;
22.         }
23.     }

 

The solution is that UI elements should be moved by buttonsRT.anchoredPosition and target.anchoredPosition.
