Spawning fake players

How do i spawn a faked player, which is accesibble like a normal player or a basic entity? I know, i will have to use the PlayOutSpawn...packet, but how do i generate a fake player for/from it?

Serializator Thx, but i forgot to say, that would like to avoid the uasage of an API

 

It is possible but you need to do allot. If you want to spawn them and do nothing with it you maybe can use packets.

 

I found this online, I don't really remember the poster sorry ;/
