vec_normalize

vec_normalize (VECTOR* vector, var length);

Scales the vector to the magnitude given by length, while keeping it's direction.

Parameters:

vector	any vector
length	new magnitude

Returns:

vector

Modifies:

vector - magnitude set to length.

Speed:

Fast

Algorithm:

vector[0] *= length / vec_length(vector);
vector[1] *= length / vec_length(vector);
vector[2] *= length / vec_length(vector);

Example:

vec_normalize(vector,1); // The vector is set to the magnitude  1.
