How to spawn NPC with skin

what have you tried so far? that can be easily handled by updating the GameProfile properties.

 

So your issue is that the npc doens't have a skin applied?
Have you made some outputs for the texture values? Because the sessionservers won't allow requests that are done several times in some seconds
Edit: And maybe also outputs from your uuid if that is maybe called wrong

 

You need a Signature

 

From the profile that you get the value thing

 

I dont know, where do you get the "value" field for the profile?

 

You need to add a field to the url, this:
?unsigned=false

 

Maybe let the player force respawn after you apply the skin (that's what i had to do at one of my old Nick systems)

 

Here is my 1_11 FakePlayer class. Feel free to use it. It's MIT. It works off of a in-game player, so you'd just need to change that for a skin as shown above.

     return instance;

}

Example Usage (Create mock player on join. Just example)

Code (Java):

  private FakePlayer fakePlayer;

   public OnJoin() {
     fakePlayer = Main.getFakePlayer();
   }

   @EventHandler
   public void onJoin(PlayerJoinEvent e) {
     final Player player = e.getPlayer();
     new BukkitRunnable() {
       @Override
       public void run() {
         if (player != null && player.isOnline()) {
           fakePlayer.spawnFakePlayer(player, player.getLocation().add(1.0, 0, 1.0), player.getDisplayName());
         }
       }
     }.runTaskLater(Main.getInstance(), 3);
   }
 

Bonus that ConsoleColor.class I am using

With that you can detect right clicks and so on?

 

I'm sorry, I don't quite understand. You mean right clicking the fake player to trigger an event? If so, yes, that should work. It should be an instance of a entity in the world (I believe).

 

I mean the fakePlayer exists because with packets its only client sided (The server dont know if there is a FakePlayer) so dont fire evetns

 

Oh I see. I'd imagine you just bind the entity location with a invisible entity of your choosing (with no AI, and probably representing the correct size. A armorstand probably be best).
