vec_dist (vector1, vector2);

Returns the distance between two positions.

Parameters:

vector1 - first position vector
vector2 - second position vector

Returns:

Distance between the two vectors

Speed:

Fast

Algorithm: 

temp[0] = vector1[0] - vector2[0];
temp[1] = vector1[1] - vector2[1];
temp[2] = vector1[2] - vector2[2];
distance = sqrt(temp[0]*temp[0] + temp[1]*temp[1] + temp[2]*temp[2]);

Example:

 distance = vec_dist(my.x,your.x); // calculate distance of   MY and YOU entities
