Checking if an entity is an NPC?

How to do a background check on the NPC?

 

Code:

bool isNPC( BaseEntity e ){
      return e is BaseNPC;
}

 

How about this?

PHP:

BasePlayer player

 

I need to identify these NPC's:
Human NPC - Core for Rust | Oxide

 

Thats simple. It generates random userID for each HumanNPC by this:

Code:

var userId = (ulong) UnityEngine.Random.Range(0, 2147483647);

It tests against real humans like this:

Code:

        void KillNpc(BasePlayer player)
        {
            if (player.userID >= 76560000000000000L || player.userID <= 0L || player.isDestroyed) return;
            cache.Remove(player.userID);
            player.KillMessage();
        }

 

Code:

bool isNPC(ulong _id)
{
   if (_id < 76560000000000000L) return true;
   else return false;
}

 

Code:

static bool isNPC(ulong id) => id < 76560000000000000L;
