You can use OnMouseDrag() because it works on both the editor and mobile so it's easier to test. It works for 3D objects as well as long as they have a collider.

• Create a script.

• Add the function below to the script and attach it to your sprite.

• Make sure to add a collider2d to your sprite otherwise it won't work.

   void OnMouseDrag() { Vector3 mousePosition = new Vector3(Input.mousePosition.x, Input.mousePosition.y, -1*(Camera.main.transform.position.z)); Vector3 objPosition = Camera.main.ScreenToWorldPoint(mousePosition); transform.position = objPosition; }
