Difficult zone of reading C # Unity3D values

Question

There is a Rect from which mouse clicks are taken, limited by the coordinates of the camera anchors.

bounds = new Rect(upLeft.transform.position.x, downRight.transform.position.y, downRight.transform.position.x - upLeft.transform.position.x, upLeft.transform.position.y - downRight.transform.position.y); if (Input.GetMouseButtonDown(0) && bounds.Contains(Input.mousePosition)) { Began(Input.mousePosition); }

How to add areas to it - exceptions? Suppose it is necessary that from this Rect the upper right corner, for example, the upper right corner was inactive + the lower right corner was inactive. I think it should look like this

 public List <Rect> AreaException; AreaException.add(new Rect (0,0, 30,30)); AreaException.add(new Rect (50,50,30,30));

But what to do next? It seems like they need to go through foreach and somehow remove the coordinates belonging to them from the original Rect. How to do this?

I would declare a class based on a list in which I described the verification method:

 public class AreaExceptions : List<Rect> { public bool Contains(Vector3 point) { foreach(var item in this) { if (item.Contains(point) return true; } return false; } }

Well, the code will be:

 bounds = new Rect(upLeft.transform.position.x, downRight.transform.position.y, downRight.transform.position.x - upLeft.transform.position.x, upLeft.transform.position.y - downRight.transform.position.y); var exepts = new AreaExceptions(); exepts.Add(new Rect (0,0, 30,30)); exepts.Add(new Rect (50,50,30,30)); if (Input.GetMouseButtonDown(0) && bounds.Contains(Input.mousePosition) && ! exepts.Contains(Input.mousePosition)) { Began(Input.mousePosition); }

The only thing - the coordinates need to be recalculated from relative to the coordinates of the source rectangle

@Dmitrii, well, your exclusion zones exist inside the tracked rectangle, but the coordinates in the exceptions in my proposed solution are specified in absolute (relative to the rectangle) coordinates.
