Solved getConfig().set does not work!

Hello I am having a error on the getconfig().set here:

Code:java

        if (cmd.getName().equalsIgnoreCase("setspawn")) {
                getConfig().set("spawn.world", p.getLocation().getWorld().getName());
                getConfig().set("spawn.x", p.getLocation().getX());
                getConfig().set("spawn.y", p.getLocation().getY());
                getConfig().set("spawn.z", p.getLocation().getZ());
                saveConfig();
                p.sendMessage(ChatColor.GREEN + "Spawn set!");
                return true;
        }

I cant seem to find what's wrong with it..

 

What is the stack trace/problem?

 

@Sean0402 Can we see the saveConfig() method?​

 

It's probably in the main class, saveConfig() is part of JavaPlugin...

 

Traks it says this but am note sure what to do

A double isn't an object, try setting the value of the locations in the configuration to p.getLocation().getX() + "" and y and z accordingly. Or use the constructor for Double to create a new Double object

 

Traks wat, that should still compile fine

 

Traks fireblast709 Yeah, Java auto-converts? simple-types into objects. That's why you can do Map<String, Integer>.put("Hey", 31415); without needing a String object and an Integer object

 

Traks Well it works but when I do /setspawn is sets the spawn but then when I type /spawn I go into the void?

My /spawn code:

Code:java

 if (cmd.getName().equalsIgnoreCase("spawn")) {
                if (getConfig().getConfigurationSection("spawn") == null) {
                        p.sendMessage(ChatColor.RED + "The spawn has not yet been set!");
                        return true;
                }
                World w = Bukkit.getServer().getWorld(getConfig().getString("spawn.world"));
                double x = getConfig().getDouble("spawn.x");
                double y = getConfig().getDouble("spawn.y");
                double z = getConfig().getDouble("spawn.z");
                p.teleport(new Location(w, x, y, z));
                p.sendMessage(ChatColor.GREEN + "Welcome to the spawn!");
        }

fireblast709 Zettelkasten It was the only logical reason I could come up with. Perhaps the OP is using on old Java version to compile with?

 

Traks the error does suggest it. Nonetheless I have never seen it happen before.

Sean0402 when does that error occur? Also, can you provide a bigger screenshot / Java version

 

fireblast709 My Main Class:

Code:java

package me.sean0402.teleport;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Location;
import org.bukkit.World;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Teleport extends JavaPlugin {
 
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
 
        if (!(sender instanceof Player)) {
                sender.sendMessage(ChatColor.RED + "This plugin is for players only!");
                return true;
        }
 
        Player p = (Player) sender;
 
        if (cmd.getName().equalsIgnoreCase("tp")) {
                if (args.length == 0) {
                        p.sendMessage(ChatColor.RED + "Please specify a player.");
                        return true;
                }
                Player target = Bukkit.getServer().getPlayer(args[0]);
                if (target == null) {
                        p.sendMessage(ChatColor.RED + "Could not find player " + args[0] + "!");
                        return true;
                }
                p.teleport(target.getLocation());
                return true;
        }
 
        if (cmd.getName().equalsIgnoreCase("setspawn")) {
                getConfig().set("spawn.world", p.getLocation().getWorld().getName());
                getConfig().set("spawn.x", p.getLocation().getX() + "spawn.x");
                getConfig().set("spawn.y", p.getLocation().getY() + "spawn.y");
                getConfig().set("spawn.z", p.getLocation().getZ() + "spawn.z");
                saveConfig();
                p.sendMessage(ChatColor.GREEN + "Spawn set!");
                return true;
        }
 
        if (cmd.getName().equalsIgnoreCase("spawn")) {
                if (getConfig().getConfigurationSection("spawn") == null) {
                        p.sendMessage(ChatColor.RED + "The spawn has not yet been set!");
                        return true;
                }
                World w = Bukkit.getServer().getWorld(getConfig().getString("spawn.world"));
                double x = getConfig().getDouble("spawn.x");
                double y = getConfig().getDouble("spawn.y");
                double z = getConfig().getDouble("spawn.z");
                p.teleport(new Location(w, x, y, z));
                p.sendMessage(ChatColor.GREEN + "Welcome to the spawn!");
        }
        return true;
}
}

 

Sean0402 well that + "spawn.x" part causes the coords to be 0,0,0 when using getDouble

 

fireblast709 what should I put it to?

 

Sean0402 you should remove the whole String part, it causes the double to be a String which isn't a valid double

 

fireblast709 Explain what you mean? And where to move what?

 

Sean0402

Code:java

p.getLocation().getY() + "spawn.y"

to

Code:java

p.getLocation().getY()

etc

 

fireblast709 But now I got the same error I got from the beginning doing that.. The getConfig().set is not working

 

Sean0402 once more, where exactly do you get the error, and are there actual stacktraces involved (no, just referring me to the previous screenshot will not suffice )

 

What's the Java version used for compiling set to? In Eclipse it can be found at Preferences > Java > Compiler > Compiler compliance level

 

Traks 1.4

fireblast709 this part is the error:

Code:java

getConfig().set("spawn.x", p.getLocation().getX());
                getConfig().set("spawn.y", p.getLocation().getY());
                getConfig().set("spawn.z", p.getLocation().getZ());

Change it to 1.6, 1.7 or 1.8 depending on what Java version you have installed for executing Java applications

 

Traks Thanks! Works perfect now!
