java - Bukkit 插件从 config.yml 获取位置

Question

我正在尝试创建插件，它将在有人打开箱子时检查箱子的位置是否与我的 config.yml 中的任何位置不匹配。所以我想做这样的事情:

ArratList<Location> list = new ArrayList();
foreach(get world, x, y, z from each key in section Locations in my config) {
    list.add(new Location(world, x, y, z));
    foreach(Location l : list) {
    if(l == p.location...
}
}

编辑: 现在我有这个代码:

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");
                        }
                    }
                }
            }
        }
    }
}

但是当我右键单击胸部时，消息 jeej 没有出现，出现的所有内容都是消息 Hodnota x je 0。但是我的配置中有几个键，并且 x 在任何地方都不为 0。在控制台中出现此错误:

您可以执行以下操作: 将您的位置保存在配置中，如下所示:

# CONFIG.YML #
location1:
 x: 0
 y: 0
 z: 0
 world: "world"
location2:
 x: ....
 .
 .

然后，为了获取所有配置:

ArrayList<Location> listLocations = new ArrayList<Location>();
for (String key : getConfig().getKeys(false) ){
    //We are getting every key from our config.yml file
    ConfigurationSection location = getConfig().getConfigurationSection(key);
    int x = location.getInt(key + ".x");
    int y = location.getInt(key + ".y");
    int z = location.getInt(key + ".z");
    String world = location.getString(key + ".world");
    Location l = new Location(Bukkit.getWorld(world), x, y, z);
    listLocations.add(l);
}

您现在应该将该配置文件上的所有位置添加到 ArrayList listLocations 中，并且可以从那里进行检查!
