NPC nms error 1.12.2

Hello everyone, I was creating a NPCS plugin here, but in 1.8 and I decided to upgrade the jar version to 1.12 with this I realized that when trying to create an NPC nothing happens, simple message appears as if it had been spawned, however I do not see you.

Code:

public void spawn() {
        PacketPlayOutNamedEntitySpawn packet = new PacketPlayOutNamedEntitySpawn();

        setValue(packet, "a", entityID);
        setValue(packet, "b", gameprofile.getId());
        setValue(packet, "c", getFixLocation(location.getX()));
        setValue(packet, "d", getFixLocation(location.getY()));
        setValue(packet, "e", getFixLocation(location.getZ()));
        setValue(packet, "f", getFixRotation(location.getYaw()));
        setValue(packet, "g", getFixRotation(location.getPitch()));
        DataWatcher w = new DataWatcher(null);
        w.register(new DataWatcherObject<>(13,DataWatcherRegistry.a),(byte)127);
        setValue(packet, "h", w);
        addToTablist();
        sendPacket(packet);
        headRotation(entityID, location.getYaw(), location.getPitch());

        Bukkit.getScheduler().runTaskLater(Main.plugin, new Runnable() {
            @Override
            public void run() {
                rmvFromTablist();
            }
        }, 5L);
    }

    public static void teleport(int entityID, Location location) {
        PacketPlayOutEntityTeleport packet = new PacketPlayOutEntityTeleport();
        setValue(packet, "a", entityID);
        setValue(packet, "b", getFixLocation(location.getX()));
        setValue(packet, "c", getFixLocation(location.getY()));
        setValue(packet, "d", getFixLocation(location.getZ()));
        setValue(packet, "e", getFixRotation(location.getYaw()));
        setValue(packet, "f", getFixRotation(location.getPitch()));

        sendPacket(packet);
        headRotation(entityID, location.getYaw(), location.getPitch());
    }


    public static void headRotation(int entityID, float yaw, float pitch) {
        PacketPlayOutEntityLook packet = new PacketPlayOutEntityLook(entityID, getFixRotation(yaw), getFixRotation(pitch), true);
        PacketPlayOutEntityHeadRotation packetHead = new PacketPlayOutEntityHeadRotation();
        setValue(packetHead, "a", entityID);
        setValue(packetHead, "b", getFixRotation(yaw));

        sendPacket(packet);
        sendPacket(packetHead);
    }

    public static void destroy(int entityID) {
        PacketPlayOutEntityDestroy packet = new PacketPlayOutEntityDestroy(new int[]{entityID});
        rmvFromTablist();
        sendPacket(packet);
    }

    public static void addToTablist() {
        PacketPlayOutPlayerInfo packet = new PacketPlayOutPlayerInfo();
        PacketPlayOutPlayerInfo.PlayerInfoData data = packet.new PlayerInfoData(gameprofile, 1, EnumGamemode.NOT_SET, CraftChatMessage.fromString(gameprofile.getName())[0]);
        @SuppressWarnings("unchecked")
        List<PacketPlayOutPlayerInfo.PlayerInfoData> players = (List<PacketPlayOutPlayerInfo.PlayerInfoData>) NPC.getValue(packet, "b");
        players.add(data);

        setValue(packet, "a", PacketPlayOutPlayerInfo.EnumPlayerInfoAction.ADD_PLAYER);
        setValue(packet, "b", players);

        sendPacket(packet);
    }

    public static void rmvFromTablist() {
        PacketPlayOutPlayerInfo packet = new PacketPlayOutPlayerInfo();
        PacketPlayOutPlayerInfo.PlayerInfoData data = packet.new PlayerInfoData(gameprofile, 1, EnumGamemode.NOT_SET, CraftChatMessage.fromString(gameprofile.getName())[0]);
        @SuppressWarnings("unchecked")
        List<PacketPlayOutPlayerInfo.PlayerInfoData> players = (List<PacketPlayOutPlayerInfo.PlayerInfoData>) NPC.getValue(packet, "b");
        players.add(data);

        setValue(packet, "a", PacketPlayOutPlayerInfo.EnumPlayerInfoAction.REMOVE_PLAYER);
        setValue(packet, "b", players);
        sendPacket(packet);
    }

It is worth noting that only difference in the code was the change of "DataWatcher" that changed between 1.8 to 1.12

 

I see what you are trying to do, you are lucky because I saw the same video and I updated the code + extra features.

I created an Util to create NPC in Bukkit-1.12. here
