Recalling Method

Introduction:-
well i made a Nice progress is CTF Events and made its system is using Static Voids and then recalling them backs from npc or Either timer

1st question :-
Does recalling increase Cpu usage or makes server laggy or it would be better if i made the CTF Tournament Runs by Npcs ???

2nd question :-
i noticed some Codes r added in list inside Kernel or w.e anyfile in source So what does List Do and do u recommend using it in Coding ?

1. Depends what the methods do and how often they're called.
2. A list is a generic collection of an object, so yes sometimes. It call comes into what you're doing.
