Line Trace from HUD button location

Thanks! These are great for info. Any idea on how to convert this from cursor to button? Unfortunately the cursor will always be in the center of the screen because the screen rotates with it in my game.

I was able to get a workaround working with this, but I have only got this to work with changing the direction of the trace left/right and not up and down which I will need for my third point.

Please ignore the ConvertScreenLocationToWorldspace. I was just playing with that, but as you can see its not doing anything.
