public class BVector2

extends Object

implements Serializable

A vector class for BScalars. It contains 2 elements. NOTE: this is not a Vector in the java sense, but rather a vector in the computer graphics/mathematical sense. While they are similar, there are certain differences that I won't elaborate on here. Just don't think that it's like a normal java.util.Vector. provides methods for multiplying, dividing, scaling, adding and subtracting vectors. The vector array is public, so no function calls are necessary to obtain the values. Index the array using the predefined constants.
