Tell us why vectors should be normalized when used to move an object?
Answer:
Normalization makes the vector unit length. It means, for instance, that if you want to move with speed 20.0, multiplying speed * vector will result in a precise 20.0 units per step. If the vector had a random length, the step would be different than 20.0 units.
