本想写一个类似于标记的功能（如：shift+左键能使视线上的生物发光）
问题在于我只想让自己或者朋友看见这个放光轮廓的效果
所以想到用protocolLib发包 让客户端显示指定的生物附上发光药水效果

请问这能实现吗？如果可以我应该调用NMS的哪个类呢？
实在是找不到对应类了，请各位大腿能指点一下，谢谢！

----------------------------------------------------------------------------------------
以上问题已解决  新的问题又出现啦！
当reload后 再尝试发包就会出现报错！
报错如下：

呜哇 一个人都没有回复诶....

楼主都用ProtocolLib了，就没有必要调用啥NMS类了。。。
我们需要发送一个实体药水效果包（Entity Effect），其数据结构在这里。
ProtocolLib相关教程在这里。若需要详细代码请回复我。

如果我的答案有帮助的话，请给我最高的评分。

你好大腿，再打扰一下
我在运行的时候报错了 想问一下哪里写错了吗？
代码如下

  2.         @EventHandler(ignoreCancelled=true)
  3.         public void onPlayerClickEntity(PlayerInteractEntityEvent e){
  4.                
  5.                 e.getPlayer().sendMessage("发光！");
  6.                 if(isEV){
  7.                         setEntityEffect(e.getPlayer(),e.getRightClicked());
  8.                 }
  9.         }
  10.        
  11.         public void setEntityEffect(Player p , Entity en){
  12.                 PacketContainer packet = new PacketContainer(PacketType.Play.Server.ENTITY_EFFECT);
  13.                
  14.                 packet.getIntegers().write(0, en.getEntityId());//Entity ID        VarInt
  15.                 packet.getBytes().write(0, (byte)24);                        //Effect ID        Byte
  16.                 packet.getBytes().write(1, (byte)0);                        //Amplifier        Byte
  17.                 packet.getIntegers().write(1, 100);                                //Duration        VarInt
  18.                 packet.getBytes().write(2,(byte)0x02);                        //Flags                Byte
  19.                
  20.                 try{
  21.                         pm.sendServerPacket(p, packet,false);
  22.                 } catch (InvocationTargetException ex) {
  23.                         ex.printStackTrace();
  24.                 }

代码如下

https://www.spigotmc.org/resources/protocollib.1997/

PacketWrapper

WrapperPlayServerEntityEffect.java

看下里面的实现内容就知道如何设置了
不需要用这个库,看他里面是如何write的就行了←_←
你没报错根本不知道错在哪里

PacketWrapper

我看到了entity effect的实现和参数 都write进去了。
报错就是看到了我这个setEntityEffect用protocol发包报错了
明天我把报错贴上来吧  谢谢大腿的回复！

PacketWrapper

大腿你好 我把你发的实现内容一个一个write进去了
结果是发包完全没反应....到底是为什么呢....
还有我发现报错是在reload之后才会出现，reload前就是没反应的（插件正常 发包没任何显示了...）
代码如下

  2. public void setEntityEffect(Player p , Entity en){
  3.                 PacketContainer packet = new PacketContainer(PacketType.Play.Server.ENTITY_EFFECT);
  4.                
  5.                 packet.getIntegers().write(0, (int)en.getEntityId());        //Entity ID        VarInt
  6.                 packet.getBytes().write(0, (byte)(24&255));                                //Effect ID        Byte
  7.                 packet.getBytes().write(1, (byte)(0&255));                                //Amplifier        Byte
  8.                 packet.getIntegers().write(1, (int)100);                                //Duration        VarInt
  9.                 packet.getBytes().write(2,(byte)1);                                                //Flags                Byte
  10.                
  11.                 try{
  12.                         pm.sendServerPacket(p, packet,false);
  13.                 } catch (InvocationTargetException ex) {
  14.                         ex.printStackTrace();
  15.                 }
  16.         }
