Java 如何获得播放器'；插口中的s ping 1.16.4

我尝试以多种方式使用java反射来获得玩家的ping。但在100%时，它返回0毫秒

我已经找了很久了，所以。。。有人能帮我吗

尝试1:

    public static int getPing(Player p) {

       try {

           Object craftPlayer = (CraftPlayer) p;
           return (int) craftPlayer.getClass().getField("ping").get(craftPlayer);

       } catch (IllegalArgumentException | IllegalAccessException | NoSuchFieldException | 
       SecurityException e) {
           throw new Error(e);
       }

    }

    public static int getPing(Player p) {

       EntityPlayer player = ((CraftPlayer) p).getHandle();
       return player.ping;

    }
    

    int ping = 0;
    Class<?>[] parameterTypes = null;
        
    Class<CraftPlayer> metadata = CraftPlayer.class;
    Method[] methods = metadata.getDeclaredMethods();
    for(Method method : methods) {  
        if(method.getName().equalsIgnoreCase("getHandle")) {
            parameterTypes = method.getParameterTypes();
        }
    }
        
    try {

        Object entityPlayer = p.getClass().getDeclaredMethod("getHandle", 
        parameterTypes).invoke((CraftPlayer) p);
        ping = (int) entityPlayer.getClass().getDeclaredField("ping").get(entityPlayer);

    } catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException
                | NoSuchMethodException | SecurityException | NoSuchFieldException e) {
            e.printStackTrace();
        }

        int ping = 0;
        
        try {

            Object entityPlayer = p.getClass().getMethod("getHandle").invoke(p);
            ping = entityPlayer.getClass().getField("ping").getInt(entityPlayer);

        } catch (IllegalArgumentException | IllegalAccessException | NoSuchFieldException | 
        SecurityException e) {
            e.printStackTrace();
        }

Try2:

    public static int getPing(Player p) {

       try {

           Object craftPlayer = (CraftPlayer) p;
           return (int) craftPlayer.getClass().getField("ping").get(craftPlayer);

       } catch (IllegalArgumentException | IllegalAccessException | NoSuchFieldException | 
       SecurityException e) {
           throw new Error(e);
       }

    }

    public static int getPing(Player p) {

       EntityPlayer player = ((CraftPlayer) p).getHandle();
       return player.ping;

    }
    

    int ping = 0;
    Class<?>[] parameterTypes = null;
        
    Class<CraftPlayer> metadata = CraftPlayer.class;
    Method[] methods = metadata.getDeclaredMethods();
    for(Method method : methods) {  
        if(method.getName().equalsIgnoreCase("getHandle")) {
            parameterTypes = method.getParameterTypes();
        }
    }
        
    try {

        Object entityPlayer = p.getClass().getDeclaredMethod("getHandle", 
        parameterTypes).invoke((CraftPlayer) p);
        ping = (int) entityPlayer.getClass().getDeclaredField("ping").get(entityPlayer);

    } catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException
                | NoSuchMethodException | SecurityException | NoSuchFieldException e) {
            e.printStackTrace();
        }

        int ping = 0;
        
        try {

            Object entityPlayer = p.getClass().getMethod("getHandle").invoke(p);
            ping = entityPlayer.getClass().getField("ping").getInt(entityPlayer);

        } catch (IllegalArgumentException | IllegalAccessException | NoSuchFieldException | 
        SecurityException e) {
            e.printStackTrace();
        }

尝试3:

    public static int getPing(Player p) {

       try {

           Object craftPlayer = (CraftPlayer) p;
           return (int) craftPlayer.getClass().getField("ping").get(craftPlayer);

       } catch (IllegalArgumentException | IllegalAccessException | NoSuchFieldException | 
       SecurityException e) {
           throw new Error(e);
       }

    }

    public static int getPing(Player p) {

       EntityPlayer player = ((CraftPlayer) p).getHandle();
       return player.ping;

    }
    

    int ping = 0;
    Class<?>[] parameterTypes = null;
        
    Class<CraftPlayer> metadata = CraftPlayer.class;
    Method[] methods = metadata.getDeclaredMethods();
    for(Method method : methods) {  
        if(method.getName().equalsIgnoreCase("getHandle")) {
            parameterTypes = method.getParameterTypes();
        }
    }
        
    try {

        Object entityPlayer = p.getClass().getDeclaredMethod("getHandle", 
        parameterTypes).invoke((CraftPlayer) p);
        ping = (int) entityPlayer.getClass().getDeclaredField("ping").get(entityPlayer);

    } catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException
                | NoSuchMethodException | SecurityException | NoSuchFieldException e) {
            e.printStackTrace();
        }

        int ping = 0;
        
        try {

            Object entityPlayer = p.getClass().getMethod("getHandle").invoke(p);
            ping = entityPlayer.getClass().getField("ping").getInt(entityPlayer);

        } catch (IllegalArgumentException | IllegalAccessException | NoSuchFieldException | 
        SecurityException e) {
            e.printStackTrace();
        }

还有3个。。。（与此类似或显然不适合使用）

我正在VPS托管的1.16.4PC服务器上测试我的插件

在专用机器上可能会有所不同

我尝试使用“紧凑”代码，如下所示：

int ping = ((CraftPlayer) p).getHandle().ping;

。。。但它再次返回0毫秒

请注意，我是一个真正的Java新手。我在练习提高我的水平

我不是在寻找最终的解决方案，但如果我的方案可行的话，我只是在寻找答案。如果没有，这是一个很好的方法。

最后，它起作用了

问题是我的FAI：几天前，我为UDP/TCP打开了25565个端口，我还更改了其他参数

由于我关闭了所有这些选项，我的ping神奇地回到了8-12毫秒
