||Gets the value at the given index. (Indices 0 and 1 are equal to x and y, respectively.)|
||Length||Returns the length of this vector.|
||Normalize||Returns the normalization factor for this vector. (See Remarks.)|
||Sets the value at the given index to the given value. (Indices 0 and 1 are equal to x and y, respectively.)|
||SqrLength||Returns the length-squared of this vector.|
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.
