Current Position in the WindowView

Let say I have a 1000 x 1000 Layout Size, but my Window Size is only say 250 x 250. Is there a way to get the current CENTER of the Window View?

No matter what I try it measures the X/Y event from the top left 0,0 of the layout, I want it to get from the current Window view, so if I have moved my Hero down 50 pixels my window Center would be somewhere in the 175.

Thanks

Standard algorithm:

ViewportLeft+(ViewportRight-ViewportLeft)/2

thank you So that might be the ticket, BUT what is THIS?

Viewportleft(THIS)+(Viewportright(THIS)-Viewportleft(THIS))/2

in the editor it says layer, does it mean a Layer I built like HUD? if so that is not working like I expect.

THIS means the name of the viewport.

(This), actually means the number of the layer your getting the coordinate off...
