Top-Down Gamemode Help.

[JaceQuads]

Hello, I've mostly been lurking on Facepunch but now I really need some help.
I'm trying to get a top-down view, and have the player shoot if the cursor is over an elevated surface at that surface.
I have this mostly working, but it also moves the camera around, and I can't seem to get the camera to stay at the same height and distance from the player. Any help is appreciated!

All is being ran clientside.
