calculating the distance

how do I calculate the distance between 2 models?

c_trace?
c_scan?

thanks in advance

vec_dist( my.x, you.x )

alternatively you can use the Pythagoras
(in case you handle your vectors seperated as variables, and
want do a "selfmade" calculation)

a*a+b*b=c*c

or:

c=sqrt(a*a+b*b)

O.o

Where a = my.x - you.x and b = my.y - you.y.
c is the distance

Yes, forgot to add that.
Its just the classic way to calculate distances in
geometry. (a and b beeing the "x" and "y" distances between
the objects positions)

-> its more useful when you dont want the (z) hight of the objects
to influence the distance.

You can also use (a*a)+(b*b)+(c*c) = d (d is the distance², a-c = x-z). I assume that you are using a 3D Space...
