Question

我试图创建插件，如果胸部的位置与我的config.yml中的任何位置都不匹配，则会检查有人打开胸部的时间。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：现在我有了这段代码：

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，所有出现的内容都是消息Hodnota x je 0.但是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：

Answer 1

您可以做的是以下内容：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，为了得到我们所有的配置：

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中的所有位置都放到ArrayList listLocations中，并且可以从那里进行检查！

Answer 2

您不需要从配置中获取每个单独的值（x，y，z，world），因为：

Location implements ConfigurationSerializable，这意味着您可以使用config#set("path.to.location", yourLocation);和yourLocation = (Location) config#get("path.to.location");

现在，你的例外：

我建议您learn how to read stacktraces，因为这对您将来非常有帮助。

从以下几行：

       java.lang.IllegalArgumentException: Name cannot be null
        at org.apache.commons.lang.Validate.notNull(Validate.java:192) ~[spigot.jar:git-Spigot-5391d73-0ebb9c7]

        at org.bukkit.Bukkit.getWorld(Bukkit.java:500) ~[spigot.jar:git-Spigot-5391d73-0ebb9c7]
        at me.sudoman281.chestTreasure.Listeners.onPlayerInteract(Listeners.java:47) ~[?:?]

我知道您曾（间接）调用Bukkit.getWorld(null);，因为此处的世界为空String world = location.getString(key + ".world"); 检查您的配置路径，（但是，我建议您只使用上面提到的位置）

Bukkit插件从config.yml获取位置
