Question by Christinezhang · May 11, 2020 at 08:17 AM · gameobjectraycastunity 2d

why gameobject / raycast when dragged is not accurately following the touch position in unity

so I made a script for multitouch using raycast. when dragged faster, the gameobject will be released, but when moving the gameobject slowly it follows the touch. here the codes

 void FixedUpdate()
 {
 
     Debug.Log(Input.touchCount);
     if (Input.touchCount > 0)
     {
         touch[Input.touchCount-1] = Input.GetTouch(Input.touchCount-1);
         Vector2 worldPoint = Camera.main.ScreenToWorldPoint(touch[Input.touchCount-1].position);
         RaycastHit2D hit = Physics2D.Raycast(worldPoint, Vector2.zero, Mathf.Infinity);
 
         if (hit.transform != null)
         {
             if (touch[Input.touchCount - 1].phase == TouchPhase.Moved)
             {
                 hit.transform.position = worldPoint;]
             }
 
             else if (touch[Input.touchCount-1].phase == TouchPhase.Began)
             {
                 startPos[touch[Input.touchCount-1].fingerId] = worldPoint;
             }
 
             else if (touch[Input.touchCount-1].phase == TouchPhase.Ended)
             {
                 hit.transform.position = startPos[touch[Input.touchCount-1].fingerId];
             }
         }
     }
 }

what can i do for drag faster without gameobject will released? sorry for my bad english
