Looking Hyper

This script will help you to create movement using the mouse or touch (in android).

This type of movement is one of the most common in hyper casual games.

The code consists of 3 main parts:

1. Getting the mouse position (if in editor)

2. Getting the finger position (if in android)

3. moving the player according to the position

    public float barrierXmin = -4f;

   void Start()
   {
       rigidbody = GetComponent<Rigidbody();
   }

       if (Input.touchCount > 0)
       {
            Vector3 fingerPos = Input.touches[0].position;
            fingerPos.z = 10;
            fingerPos = Camera.main.ScreenToWorldPoint(fingerPos);
