What I am asking, is how do you disable vertical aiming, but keeping horizontal aiming?

How to disable vertical aiming?

This isn't very precise mathematically. Let's make it so.
More or less, this means whatever we are doing, the y portion of the "aim" is ignored. For example, if the "aim" is the mouse's position in 3D space, then we just ignore its y position.
If it's displacement, again, just ignore the y; if it's a direction, again, ignore the y.
A simple way to "ignore the y" is to multiply it out to be 0:
dir = Vector3.new(0.4, 0.5, 0.3)
print( dir * Vector3.new(1, 0, 1) )
-- (0.4, 0, 0.3)
That turns the direction into something flat in the plane -- so it will ignore how much up-and-down there is, but still keep the other senses of direction.

How exactly would I use this, Blue Taslem?
If you have a direction or a displacement, the multiplication "flattens" it. Then use the "flattened" direction instead of the original one.
