Question

我正在尝试创建一个发送包含虚假实体的数据包的插件。此外，我希望虚假实体能够在玩家看起来的位置后不断传送。

故障：

我不知道如何传送看到位置的球员背后的实体。
当播放器从特定高度落下并且使用Particelpackets时出现错误信息（请参阅错误）。

我的代码：

package com.gmail.apply55gx.UltimateAntiCheat.Packets;


public class PacketsCore implements Listener{

private EntityPlayer npc;


Player GhostPlayer;
MinecraftServer server = ((CraftServer) Bukkit.getServer()).getServer();
WorldServer world = ((CraftWorld)Bukkit.getServer().getWorlds().get(0)).getHandle();


@EventHandler
public void Join(PlayerJoinEvent event){

    Random r = new Random();
    ArrayList<Player> RandomGhostPlayer = new ArrayList<Player>();
    for(Player online : Bukkit.getServer().getOnlinePlayers()) {
        RandomGhostPlayer.add(online);
    }
    int index = r.nextInt(RandomGhostPlayer.size());
    GhostPlayer = (Player) RandomGhostPlayer.get(index);


    npc = new EntityPlayer(server, world, new GameProfile(GhostPlayer.getUniqueId(), GhostPlayer.getName()), new PlayerInteractManager(world));



    //NPC
    npc.teleportTo(event.getPlayer().getEyeLocation().add(0,2,0),false);

    PlayerConnection connection = ((CraftPlayer) event.getPlayer()).getHandle().playerConnection;

    connection.sendPacket(new PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.ADD_PLAYER, npc));
    connection.sendPacket(new PacketPlayOutNamedEntitySpawn(npc));


}


@EventHandler
public void move(PlayerMoveEvent event){


    Player p = event.getPlayer();

    try {
        npc.teleportTo((p.getLocation().add(0,3,0)),false);
        PlayerConnection connection = ((CraftPlayer) event.getPlayer()).getHandle().playerConnection;
        connection.sendPacket(new PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.ADD_PLAYER, npc));
        connection.sendPacket(new PacketPlayOutNamedEntitySpawn(npc));

        npc.setLocation(p.getLocation().getX(),p.getLocation().getY() + 3,p.getLocation().getZ(),p.getLocation().getDirection().getBlockX(),p.getLocation().getDirection().getBlockY());
    }catch (Exception e){}


    p.sendMessage("tp");





}

}

Answer 1

如果您想创建和移动假玩家，请查看ProtocolLib和PacketWrappers。此外，您还可以找到FakePlayer here的开源实现。

编辑：由于您可能正在编写反热编程，请查看Killaura-Bot-Check。
