问题
I'm trying to create plugin, that will check when someone open the chest if the chest's location doesn't match with any location in my config.yml. So I want to do something like this:
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...
}
}
EDIT: Now I have this code:
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");
}
}
}
}
}
}
}
But when I rightclick the chest, message jeej doesnt appear, everything what appears is message Hodnota x je 0. But I have several keys in my config and x is not 0 anywhere. In console this error appears:

What you can do is the following: Save your location in your configs as the following:
# CONFIG.YML #
location1:
x: 0
y: 0
z: 0
world: "world"
location2:
x: ....
.
.
And then, to get all the configs we go:
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);
}
You now should have all the locations that are on that config file to the ArrayList listLocations, and can make your checks from there!
回答2:
You do not need to get each individual value (x, y, z, world) from the config since:
Location implements ConfigurationSerializable, which means that you can just use config#set("path.to.location", yourLocation); and yourLocation = (Location) config#get("path.to.location");
Now, to your exception:
I suggest you learn how to read stacktraces, as that would be very helpful to you in the future.
From these lines:

I understand that you called Bukkit.getWorld(null); (indirectly), because world is null here String world = location.getString(key + ".world");
Check your config path, (However, I recommend you just use Location as I mentioned above)
