Function vm_GetNormalizedDir

vecmat/vector.cpp:406–409

Computes a normalized direction vector between two points Parameters: dest - filled in with the normalized direction vector start,end - the start and end points used to calculate the vector Returns: the distance between the two input points

//					start,end - the start and end points used to calculate the vector
// Returns:		the distance between the two input points
float vm_GetNormalizedDir(vector *dest, vector *end, vector *start) {
  vm_SubVectors(dest, end, start);
  return vm_NormalizeVector(dest);
}

// Returns a normalized direction vector between two points
// Just like vm_GetNormalizedDir(), but uses sloppier magnitude, less precise
