感谢你们解决了我愚蠢但希望很容易解决的问题，伙计们！你是最棒的！
问题
尝试从侦听器中删除构造函数。
在你的主要 class:
private static MazeMain instance;
// Does not need override
public void onEnable(){
PluginManager manager = Bukkit.getPluginManager();
manager.registerEvents(new EventHandle(), this);
// Make the instance of this class available for other classes
instance = this;
// Your config generator
// You don't need to log enabling and disabling
// ^(Bukkit does that automatically)
}
public void onDisable(){
instance = null;
}
public static MazeMain getInstance(){
return instance;
}
在你的监听器中，删除这个：
public EventHandle(MazeMain plugin){
plugin.getServer().getPluginManager().registerEvents(this, plugin);
Plugin = plugin;
}
另外，把
全部改掉
Plugin.getConfig()
和
MazeMain.getInstance().getConfig()
额外
永远不要存储玩家和位置对象！ 就像方块对象一样，它非常重并且会导致内存泄漏。如果你不想要大量的滞后，我建议你将对象转换为 string/UUID.
Player: Player.getUniqueId() 会给你 UUID，然后你可以做 Bukkit.getPlayer(UUID) 再次获取 Player 对象（记得检查对象是否不为空）。
位置：存储世界name/UID，x, y, z, yaw, pitch 在一个字符串中，由一个字符分隔。通过拆分字符串将其变成一个对象并实例化一个新的 Location。如果您只是要保留方块的位置，那么在这种情况下您不需要偏航和俯仰（它与玩家的视线有关）。
请记住 classes 中的 private/public/protected 标志。
您应该修复弃用问题，因为它很快就会失去支持。由于有更好的解决方案，它正在失去支持。
此外，为什么要将 ChatColors 存储在变量中？
希望以上内容对您有所帮助！欢迎提出更多问题！ :)
