"A ratio" is not a unit vector

looks like a ratio to me

It returns the unit vector of a given vector

i said essentially the same thing and you suddenly tell me it's right

Treynolds416:
The important part is that the magnitude is one. You're making a big deal out of nothing, you know what it is now.

Anyway I feel guilty for partly filling this thread up with bullstuff, so here's the math you need

--- Code: ---function getDifVec(%orig,%pos,%vec)
{
return vectorScale((vectorSub(%pos,%orig)),%mag);
}

--- End code ---
%orig is the would be the position of the golf club head, %pos is where it hits the object, %mag is how hard you want the hit to be

Xalos:
Think, normalization of a vector is, as Treynolds said, finding the unit vector - that is, changing the length (magnitude) of the vector so that it's one unit long - hence, unit vector.
