所以目前我有这个代码：

@Override

public void onEnable(){

    ProtocolManager manager = ProtocolLibrary.getProtocolManager();
    manager.addPacketListener(
            new PacketAdapter(this, ListenerPriority.HIGHEST,
                    PacketType.Play.Server.NAMED_SOUND_EFFECT) {
                @Override
                public void onPacketSending(PacketEvent event) {
                    // Item packets (id: 0x29)
                    if (event.getPacketType() ==
                            PacketType.Play.Server.NAMED_SOUND_EFFECT) {
                        if (packet.getSoundEffetcs().getValues().contains(Sound.BLOCK_PISTON_CONTRACT || packet.getSoundEffetcs().getValues().contains(Sound.BLOCK_PISTON_EXTEND))){

                        }

                        event.setCancelled(true);
                    }
                }
            });
}

@Override
public void onDisable() {
    // Plugin shutdown logic
}

}

它不完整，一旦完成它应该取消所有发送到涉及活塞声音的服务器/客户端的数据包。代码if (packet.getSoundEffetcs().getValues().contains(Sound.BLOCK_PISTON_CONTRACT || packet.getSoundEffetcs().getValues().contains(Sound.BLOCK_PISTON_EXTEND))) 给我带来了麻烦，因为“packet.getSoundEffects()”告诉我它“无法将符号“packet”解析为错误。我必须将哪些导入添加到我的插件中才能正确识别“数据包”？

【解决方案1】：

您永远不会定义 packet 变量。

你必须这样做：

@Override
public void onPacketSending(PacketEvent event) {
    // Item packets (id: 0x29)
    if (event.getPacketType() == PacketType.Play.Server.NAMED_SOUND_EFFECT) {
        PacketContainer packet = event.getPacket(); // get ProtocolLib packet
        List<Sound> sounds = packet.getSoundEffetcs().getValues(); // get values from it
        if (sounds.contains(Sound.BLOCK_PISTON_CONTRACT || sounds.contains(Sound.BLOCK_PISTON_EXTEND))){
             // here what you want
        }
        event.setCancelled(true);
    }
}
