Random position in rectangle, but not in a camera view
How can make a random coordinates generation, that are in rectangle AND not in a camera view?

So iteratively it would be easy, but to ensure constant runtime performance, how about something like this.
var screenRect = new Rect(20,20,400,400);
var cameraRect = new Rect(50,50,100,100);
var x = UnityEngine.Random.Range(screenRect.xMin, screenRect.xMax - cameraRect.width);
var y = UnityEngine.Random.Range(screenRect.yMin, screenRect.yMax - cameraRect.height);
x = x > cameraRect.xMin ? x + cameraRect.width : x;
y = y > cameraRect.yMin ? x + cameraRect.height : y;
Thanks, but in order to get this working, I need to get camera's view bounds in world coords. How can I get them? Quick example from random image: http://i.imgur.com/GWF55Nc.png
The view bounds in terms of what though? Pixels on the screen? Some kind of plane?
Yes, I guess pixels on the screen, like in that image. By the way, if camera won't be rotated exactly top-down, then view won't be a normal rectangle, right? So I think this code won't work. Basically what I want to do, is I have a rectangle area and I want to spawn enemy in that area, BUT not in view of camera, so player won't see how it will spawn.
So actually you want to spawn it on the plane on which it will walk right?
