[NMS] Entity move packets!

Guys, I'm making a disguises. My mob spawns, but moves not good. Here is my code -

Code:java

public static void walk( String playerName, Location old, Location newLoc )
{
  if( ids.containsKey( playerName ) )
  {
    PacketPlayOutRelEntityMoveLook packet = new PacketPlayOutRelEntityMoveLook(
            ids.get( playerName ),
            (byte) ((newLoc.getBlockX() - old.getBlockX()) * 32), // Fixed Point Format
            (byte) ((newLoc.getBlockY() - old.getBlockY()) * 32), // Fixed Point Format
            (byte) ((newLoc.getBlockZ() - old.getBlockZ()) * 32), // Fixed Point Format
            (byte) ((newLoc.getYaw() + 180) / 360), // Site says "fraction of 360", might need tweaking
            (byte) ((newLoc.getPitch() + 180) / 360)); // Site says "fraction of 360", might need tweaking
    PacketPlayOutEntityHeadRotation packett = new PacketPlayOutEntityHeadRotation();
    PacketPlayOutEntityLook packettt = new PacketPlayOutEntityLook(ids.get(playerName),(byte) ((newLoc.getYaw() + 180) / 360), (byte) ((newLoc.getPitch() + 180) / 360));
    PacketPlayOutEntityVelocity packetttt = new PacketPlayOutEntityVelocity(ids.get(playerName), Bukkit.getPlayer(playerName).getVelocity().getX(), Bukkit.getPlayer(playerName).getVelocity().getY(), Bukkit.getPlayer(playerName).getVelocity().getZ());
    PacketPlayOutRelEntityMove pack = new PacketPlayOutRelEntityMove(ids.get(playerName),
            (byte) ((newLoc.getBlockX() - old.getBlockX()) * 32), // Fixed Point Format
            (byte) ((newLoc.getBlockY() - old.getBlockY()) * 32), // Fixed Point Format
            (byte) ((newLoc.getBlockZ() - old.getBlockZ()) * 32));
    try {
        Field f = packett.getClass().getDeclaredField("a");
        f.setAccessible(true);
        f.set(packett, ids.get(playerName));
        f.setAccessible(false);
 
        Field ff = packett.getClass().getDeclaredField("b");
        ff.setAccessible(true);
        ff.set(packett, (byte) ((newLoc.getYaw() * 256.0F) / 360.0F));
        ff.setAccessible(false);
    } catch (Exception ex) {
        ex.printStackTrace();
    }
 
    for( Player p : Bukkit.getServer().getOnlinePlayers() )
    {
      ((CraftPlayer)p).getHandle().playerConnection.sendPacket(packet);
      ((CraftPlayer)p).getHandle().playerConnection.sendPacket(packett);
      ((CraftPlayer)p).getHandle().playerConnection.sendPacket(packettt);
      ((CraftPlayer)p).getHandle().playerConnection.sendPacket(packetttt);
      ((CraftPlayer)p).getHandle().playerConnection.sendPacket(pack);
    }
 
  }
}

What I should do, what packets I should add, or remove? Or what arguments in the packets I should change?

 

Just curious, why do you want to create a disguise plugin? Why not just use libs disguises?

I want to learn NMS. It has a lot of interesting interfaces.
