Solved get config?

Hello! I was wondering how would I be able to import this so it works in the config:

Code:java

  @EventHandler
  public void onKill(PlayerDeathEvent event) {
    Player p = event.getEntity();
    if ((p.getKiller() instanceof Player))
      p.getKiller().giveExp(15);
  }
 

I want people to edit how much exp they get in the config so how would I be able to do this?

Code:java

      p.getKiller().giveExp(getConfig); // Something like this?

I am a noob when it comes to doing configs....

 

You'll need to load data from the config file. Assuming you're working from the main class:

int xpToGive = getConfig().getInt("xp:");

That will load up the value located after the key "xp" in your config file. You can then simply pass that value to the giveExp function.

 

Code:java

float exp = (float) getConfig().getDouble("exp-to-give");
p.getKiller().setExp(p.getKiller().getExp() + exp);

 

VictoryShot It would be like:

Code:java

p.getKiller().giveExp(getConfig().getInt("path.here"));

path.here is where you specify which path. For example like in a config.yml:

Code:

xp:
  amount: 10

then the path will be "xp.amount".

 

Im soo confused.....

Three different people gave you CODE examples, and it would help to mention what you are confused on so people can help.

 

Yes I have done all that and put the code for the config in the onEnable but everytime I kill someone I get an error code

 

And that error is...?

 

Here is the image to the error:

My full code,
Main Class:

Code:java

package me.mike1665.killbar;
import java.util.logging.Logger;
import me.mike1665.killbar.BukkitListener;
import org.bukkit.Bukkit;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin
{
public final Logger logger = Logger.getLogger("Minecraft");
public static Main plugin;
public final BukkitListener bl = new BukkitListener(this);
 
public void onDisable()
{
PluginDescriptionFile pdfFile = getDescription();
this.logger.info(pdfFile.getName() + " Has Been Disabled!");
}
 
public void onEnable()
{
getConfig().options().copyDefaults(true);
saveConfig();
PluginDescriptionFile pdfFile = getDescription();
this.logger.info(pdfFile.getName() + " Version " + pdfFile.getVersion() + " Has Been Enabled!");
PluginManager pm = getServer().getPluginManager();
pm.registerEvents(this.bl, this);
Bukkit.getServer().getPluginManager().registerEvents(new BukkitListener(null), this);
{
}
}
}
 

The Listener:

Code:java

package me.mike1665.killbar;
 
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.PlayerDeathEvent;
 
public class BukkitListener
implements Listener
{
public static Main plugin;
 
public BukkitListener(Main instance)
{
plugin = instance;
}
@EventHandler
public void onKill(PlayerDeathEvent event) {
Player p = event.getEntity();
if ((p.getKiller() instanceof Player));
p.getKiller().giveExp(plugin.getConfig().getInt("exp.amount"));
p.sendMessage(ChatColor.GREEN + "You have earned" + plugin.getConfig().getInt("exp.amount" + "exp"));
}
}

 

VictoryShot cant you just get the int from the config and give that to the player?
ex:
player.giveExp(getConfig().getInt("Exp"))

 

Then what?

 

VictoryShot isnt that all you need? you just put that in your event that you want to give them the exp.

O wait sorry i didnt know you were trying to do that on kill....

I don't believe that works. experience is stored as a float if I am correct. But I don't really manipulate things with exp so I probably am wrong.
VictoryShot
Can you post your config.yml? For future references, you should learn to read and diagnose the stack trace yourself.

Look for the "Caused by" as this will point to exactly which line in your code is an error. It also posts the class and the type of exception. In your case, you are getting a NullPointerException (NPE) pointing at Line 22 of BukkitListener.

 

If its float couldnt you just * 1f ?

 

Peary
Most likely; but as I said in my edit, I don't work with exp.

 

VictoryShot
In your main class in your onEnable method you have the listener registered to use the value of null for the plugin variable. That is bad! Change:

Code:

Bukkit.getServer().getPluginManager().registerEvents(new BukkitListener(null), this);

To:

Code:

Bukkit.getServer().getPluginManager().registerEvents(new BukkitListener(this), this);

 

Config:

Code:

Exp: 12

Line 22:

Code:java

            p.getKiller().giveExp(plugin.getConfig().getInt("Exp"));

 

VictoryShot
That wasn't what the code said before .. try it now, then.

 

Thanks man that helped! D
