Unity why are my bots causing Fps drops?

Question

Unity

there is a script for bots like clash of clans

With 40 cubes on which this script weighs, there are drawdowns of up to 10 fps, why?

Answer 1

Because they wrote garbage somewhere.
In fact - open Profiler and see. If it's not clear, arrange beginsample/endsample and look in more detail.
Offhand - logs can slow down, distance calculations can slow down, constant SetDestionation can slow down.
