ScreenPointToRay in Orthogaphic Projection

[fffMalzbier]

Im working on a 2D point and click game and so i need ray-casting to see if i hit something on mouse-click.

I clearly understand how ScreenPointToRay works in 3d / Perspective projection but how it is working in fake 2d / Orthogaphic Projection?
For me is important to know , where to set my collider in z space.

Works just fine - I use it for handling UI elements or Maps all the time.

Set your collider anywhere in front of the camera
