Spawn NPC or objects on command?

Hello me again haha, best wishes for 2020!

Would be also nice to have npc's spawn on command when you come to the Npc TP, but not sure if it is configurable with Human Npc or Botspawn. (Maybe vanish and unvanish Human Npc?)

Or for example a boat on a sertaint location?

Greetz ^^ 

you can set like this in command i beleve
command entity.spawn scraptransporthelicopter "1.1, 2.2, 3.3" 

so the command with the x y z

i think 

so there needs to be a comma between the XYZ coords, and a dot as the decimal separator.
Thanks I will try! And with the npcs I am affraid its not configurable right?
no its not i would try to see if you can spawn with command at location
