Can't getPlayerStats() from another class?

I've been having this problem and I can't really fix it.
RPGPerks.java

Code:java

 
package me.nehuskerfan2.RPGPerks;
 
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.util.logging.Level;
 
import me.nehuskerfan2.RPGPerks.commands.Help;
import me.nehuskerfan2.RPGPerks.commands.Powerup;
 
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.configuration.file.YamlConfiguration;
import org.bukkit.plugin.java.JavaPlugin;
 
public class RPGPerks extends JavaPlugin {
 
protected RPGPerksLogger log;
public FileConfiguration playerStats = null;
public File playerStatsFile = null;
 
public void reloadPlayerStats() {
if (playerStatsFile == null) {
playerStatsFile = new File(getDataFolder(), "playerStats.yml");
}
playerStats = YamlConfiguration.loadConfiguration(playerStatsFile);
 
// Look for defaults in the jar
InputStream defConfigStream = this.getResource("playerStats.yml");
if (defConfigStream != null) {
YamlConfiguration defConfig = YamlConfiguration.loadConfiguration(defConfigStream);
playerStats.setDefaults(defConfig);
}
}
public FileConfiguration getPlayerStats() {
if (playerStats == null) {
this.reloadPlayerStats();
}
return playerStats;
}
public void savePlayerStats() {
if (playerStats == null || playerStatsFile == null) {
return;
}
try {
getPlayerStats().save(playerStatsFile);
} catch (IOException ex) {
this.getLogger().log(Level.SEVERE, "Could not save config to " + playerStatsFile, ex);
}
}
 
 
public RPGPerks(RPGPerks rpgPerks) {
// TODO Auto-generated constructor stub
}
 
public void onEnable() {
this.log = new RPGPerksLogger(this);
this.getCommand("rpgperks").setExecutor(new Help(this));
this.getCommand("powerup").setExecutor(new Powerup(this));
}
 
public void onDisable() {
 
}
 
}
 

commands/powerup.java

Code:java

 
package me.nehuskerfan2.RPGPerks.commands;
 
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.util.logging.Level;
 
import me.nehuskerfan2.RPGPerks.RPGPerks;
import me.nehuskerfan2.RPGPerks.RPGPerksLogger;
 
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.configuration.file.YamlConfiguration;
 
public class Powerup implements CommandExecutor {
 
 
 
 
public Powerup(RPGPerks rpgPerks) {
// TODO Auto-generated constructor stub
}
//a-explode
//a-poison
//a-fire
//m-smite
//m-tank
//m-pstrike
//w-firebolt
//w-barrage
//w-freeze
@Override
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
String rpgclass = getPlayerStats().getString(sender + ".class");
if(label.equalsIgnoreCase("powerup")){
if(args.length == 0){
sender.sendMessage(ChatColor.BLUE + "Here is a list of your skills");
}
}
return true;
}
 
}
 

Can you just tell me how this would work? getPlayerStats() and this.getPlayerStats() wouldn't work.

The method is not declared as static, so it is not a class method. You need to create a new instance of your class to reference it. You can either extend the main class in your commands class or create a new object like this:

Code:

RPGPerks perks = new RPGPerks();
String rpgclass = perks.getPlayerStats().getString(sender + ".class");

 

I always overlook the easiest of things.
