| - | Have some helpful descriptions to add to this class? Edit this page and add your insight to the Wiki! | + | A normalized vector is a vector whose length is equal to one, otherwise known as a unit vector. To convert a vector into a unit vector, get the normalization factor by calling the ''Normalize'' function, then divide each of the vector's x and y coordinates by that factor. |
