ScreenToWorldPoint Mouse Click not Functional at a 45 degree angle

Hello,

I am experiencing an issue with the following scripts. I am intermediate at scripting (so pardon any mistakes in the code). The following scripts work correctly when the camera is at a 90 degree angle, however when i shift that angle to 45 degree's, the script will only fire on the x axis. I want y Axis to be 0, because my game will not enable people to move up and down. As i understand, I need the z axis to do this, however Screen to world does not return z Values.

This is a unity 3d game, but my movement will only be on the x/z axis (assuming im explaining that correctly, my ship will only move left right forward and back, not up in down, resulting in a 3d space, with 2d movement (if that makes anysense).
