i made this script to limit the Gameobject within the View of the camera


void Update()
      Vector3 pos = Camera.main.WorldToViewportPoint (transform.position);
      pos.x = Mathf.Clamp01(pos.x);
      pos.y = Mathf.Clamp01(pos.y);
      transform.position = Camera.main.ViewportToWorldPoint(pos);


this piece of code is giving me result like this(image 1)

(Image 1)

whenever i drag the gameobject near the screen end the gameobject is limited but it partially crosses the camera view but i dont really want it to be like this

(Image 2)


but instead i want the gameobject to stop before camera view ends just like the above image(image 2), how can i do that please help me with this

You need to take into account the object’s width / height. Use width / 2 and height / 2.
