Is there a flaw in the DB camera system?
I've come up with two different methods of mathematically moving a projectile from the player, but niether work on DB.
The Problem:
-At each axis, the projectile is perfectly aligned with the camera.
-At each 45º variant, it is aligned.
-but inbetween the axis, and it's 45º variant, it becomes offset.
anyone aware why?
I'll include one of the methods.

This is the longer method, which uses 'if then' statements to decide what action to take.
I've decided not too include the other, since it is basically the same, only using trig.
