unity raycast mouse code example

Example 1: unity ray from mouse position

RaycastHit hit;
Ray ray = camera.ScreenPointToRay(Input.mousePosition);

if (Physics.Raycast(ray, out hit)) {
  Transform objectHit = hit.transform;

  // Do something with the object that was hit by the raycast.
}

Example 2: unity 2d raycast mouse

// detect object that was clicked using raycast

RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
 
if(hit.collider != null)
{
    Debug.Log ("Target name: " + hit.collider.name);
}
