    The vector projection of vector A onto vector B is the vector amount of A that lies in the direction of B. Decompose A into components parallel to and perpendicular to vector B. The magnitude of the parallel component times a unit vector in B's direction is the vector projection of A onto B. You can find the magnitude of the projection by taking the scalar or "dot" product of A and B: equal to the product of the magnitudes of the two vectors times the cosine of the angle between them.

    ... just don't multiply it by the unit vector

    you can use dot products, because the result is scalar product.
