Thank you Fred and Corp for a detailed reply. I'm still a bit confused about this one though
xHand-cos(a)*arrow.str/10
I've been reading maths, but this still makes no sense. So cosine {sohcahtoa) is the adjecent / hypontinuse of a triangle.
So hand = position
— the cos angle (a is a global angle)
Multiply by the arrow strength divide by 10
Hand angle is set to a minus cos angle (I don't get what this cos angle is) then it's aimed when the arrow is equal to a certain strength?
My brain man, seriously maths formulas....
