Skins

I am tring to create a NPC plugin and it is working, but since there is alredy the feature of name changing (not in the bukkit API), there must be a skin changing feature (not in the bukkit API) using the UUID.
I have tried to use UUIDFetcher to get the "skin" UUID and it did, but the skin is not showing up.

Code:

Code:java

public class Human extends EntityPlayer {
 
private Location l;
private CraftPlayer p;
 
public Human(Player player, String skinPlayer) {
super(((CraftServer) Main.getInstance().getServer()).getHandle().getServer(), ((CraftWorld) player.getWorld()).getHandle(),
new GameProfile(new UUIDFetcher(skinPlayer).call().get(skinPlayer), player.getName()),
new PlayerInteractManager(((CraftWorld) player.getWorld()).getHandle()));
this.l = player.getLocation();
p = (CraftPlayer) player;
playerConnection = new PlayerConnection(((CraftServer) Main.getInstance().getServer()).getHandle().getServer(), new NullNetworkManager(), this);
}
 
public void spawn() {
try {
World ws = world;
ws.addEntity(this);
getBukkitEntity().teleport(p);
if(p != null) {
playerInteractManager.setGameMode(EnumGamemode.valueOf(p.getGameMode().toString()));
inventory.setCarried(CraftItemStack.asNMSCopy(p.getItemInHand()));
for(int i = 0; i < inventory.armor.length; i++) {
inventory.armor = CraftItemStack.asNMSCopy(p.getInventory().getArmorContents());
}
}
 
PacketPlayOutNamedEntitySpawn packet = new PacketPlayOutNamedEntitySpawn(this);
for(Player p : Bukkit.getOnlinePlayers()) ((CraftPlayer) p).getHandle().playerConnection.sendPacket(packet);
} catch (Exception e) {
e.printStackTrace();
}
}
 
public void h() {
 
}
 
public void a(PacketPlayInSettings packetplayinsettings) {}
 
public void sendMessage(IChatBaseComponent ichatbasecomponent) {}
 
public void sendMessage(IChatBaseComponent[] arg0) {}
 
public Location getLocation() {
return l;
}
}

NPC's aren't players and as such the client doesn't check for their skins.

 

NPCs are just like normal players, Except for the fact that the server controls them, not a user.

 

Do you understand how skins work?

 

There is a database of skins and blablabla...
If there is way to change player's skin, there is a same way to change EntityPlayer's skin (There is a EntityPlayer variable in CraftPlayer class)

 

Nope, the client looks up the username of a player and then downloads the skin from an url on the skin server https://s3.amazonaws.com/MinecraftSkins/username.png and then renders the player with that skin.
However it only looks up playernames and not mob or npc names.
