Java Bukkit插件从config.yml获取位置

我有这个代码，我想当有人点击胸部时，它的位置与点击块的位置相匹配，向玩家发送一条消息：

public class Listeners implements Listener {

public Core plugin;
public Listeners(Core core) {
    this.plugin = core;
}

@EventHandler
private void onPlayerInteract(PlayerInteractEvent e) {
    if(e.getAction() == Action.RIGHT_CLICK_BLOCK) {
        if(plugin.createMode) {
            if (e.getClickedBlock().getType() == Material.CHEST) {
                e.setCancelled(true);
                Location loc = e.getClickedBlock().getLocation();
                String name = plugin.name;
                plugin.getConfig().set(name + ".world", loc.getWorld().getName());
                plugin.getConfig().set(name + ".x", loc.getBlockX());
                plugin.getConfig().set(name + ".y", loc.getBlockY());
                plugin.getConfig().set(name + ".z", loc.getBlockZ());
                plugin.saveConfig();
                e.getPlayer().sendMessage(ChatColor.GOLD + "[ChestTreasure] " + ChatColor.RESET + "Treasury chest successfully created!");
                plugin.createMode = false;
            }
        } else {
            if(e.getClickedBlock().getType() == Material.CHEST) {
                plugin.chests.clear();
                for (String key : plugin.getConfig().getKeys(false) ){
                    //We are getting every key from our config.yml file
                    ConfigurationSection location = plugin.getConfig().getConfigurationSection(key);
                    String world = location.getString(key + ".world");
                    int x = location.getInt(key + ".x");
                    int y = location.getInt(key + ".y");
                    int z = location.getInt(key + ".z");
                    e.getPlayer().sendMessage("Hondnota x je " + String.valueOf(x));
                    Location l = new Location(Bukkit.getWorld(world), x, y, z);
                    plugin.chests.add(l);
                }
                for(Location l : plugin.chests) {
                    e.getPlayer().sendMessage(String.valueOf(e.getClickedBlock().getLocation().getX()));
                    if(l == e.getClickedBlock().getLocation()) {
                        e.getPlayer().sendMessage("Jeej");
                    }
                }
            }
        }
    }
}

} 但当我右击胸部时，消息jeej没有出现，所有出现的都是消息Hodnota x je 0。但我的配置中有几个键，x在任何地方都不是0。在控制台中出现此错误：

我真的不需要阅读更多的内容，就可以知道onPlayerInteract中的某些内容为null，并且它与getWorld有关，因此，如果没有更多信息，我非常确定这一行是一个问题：

Location l = new Location(Bukkit.getWorld(world), x, y, z);

我猜您的变量

world

是空的，因为它是从配置中获取的，这很可能意味着它在配置中不存在。 这些线很可能是问题所在：

for (String key : plugin.getConfig().getKeys(false) ){
                    //We are getting every key from our config.yml file
                    ConfigurationSection location = plugin.getConfig().getConfigurationSection(key)

您将获得每个键的ConfigurationSection。但这些很可能不是配置部分。我相信您有一个名为location或其他的配置部分，如果是这样的话，您应该这样做：

ConfigurationSection location = plugin.getConfig().getConfigurationSection("location")

相反

我不确定您是否将configurationsection称为location，但我猜，只需将location替换为实际分区的名称即可

在不知道配置外观的情况下，这是我能回答的最好答案

ConfigurationSection location = plugin.getConfig().getConfigurationSection("location")
