Thank you

they? o.O:D

This is optimization by speed chnages.

for example we need check distance less 5 to target.

GerDistance() < 5 is same (if drop details) as sqrt(x*x+y*y+z*z) < 5

IsWithin(..,5) is same as x*x+y*y+z*z < 5*5

Second version lot more faster in result avoid call sqrt function.
