ArchWorm look a poopie!
I noticed that by VECTOR he means SCALAR. A vector is a magnitude and direction combined, whilst a scalar is simply magnitude. For clarity, what he is doing is creating an x,y,Ø vector, and a 'z' scalar (for height).
I will be releasing one of this humdingers not to compete with this one, but simply to polish up my math skills. GJ on this system I love the idea.
Ø = Theta (angle)
Edit: When going through it I was so confused how he incorporated height with vectors, but now I see they are just scalars.
Edit: Oops sorry, I see the vectors now. This point has just been proven useless 'hoorah'
