java - 每个玩家的击杀次数始终相同。 (布基特)

Question

当我编码时，我测试了我的插件，这似乎发生了:基本上，当一名玩家杀死另一名玩家时，他的击杀数就会增加一。然而，当一名玩家完成 5 次击杀时，所有其他玩家也会如此。这是我的代码:

    public class KillDeathCounter extends JavaPlugin {

    public void onEnable() {
        new PlayerListener(this);
        getLogger().info("Players will not be able to kit spam.");

        this.getConfig().addDefault("playerkills", 0);
        this.getConfig().addDefault("playerdeaths", 0);
        this.getConfig().options().copyDefaults(true);

        saveConfig();
    }

    public void onDisable() {
        getLogger().info("Kill Death Counter has been disabled.");
        saveConfig();
    }

    public boolean onCommand(CommandSender sender, Command cmd, String label,
            String[] args) {

        if (cmd.getName().equalsIgnoreCase("digipvp")) {
            Player p = (Player) sender;
            p.sendMessage(ChatColor.AQUA
                    + "Our PVP plugin was developed by Pierre Lichtlé, the owner, also known as Master Digi."
                    + " If you would like to contact him for a plugin, send him an email at developer.petlamb@gmail.com."
                    + " Thanks for playing on our server!");

            return true;

        }

        return false;
    }
}


    package me.katsunicalis.plugin;

import org.bukkit.ChatColor;
import org.bukkit.Statistic;
import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDeathEvent;
import org.bukkit.event.entity.PlayerDeathEvent;

public class PlayerListener implements Listener {

    KillDeathCounter kdc;



    public PlayerListener(KillDeathCounter plugin) {
        plugin.getServer().getPluginManager().registerEvents(this, plugin);
        kdc = plugin;
    }

    @EventHandler
    public void playerKillsPlayer(EntityDeathEvent e) {


        Entity deade = e.getEntity();

        Entity killer = e.getEntity().getKiller();

        if (killer instanceof Player && deade instanceof Player){



            int kills = kdc.getConfig().getInt("playerkills");
            int deaths = kdc.getConfig().getInt("playerdeaths");
            kdc.getConfig().set("playerkills", kills += 1);
            kdc.getConfig().set("playerdeaths", deaths += 1);


            killer.sendMessage("You now have " + kills + " kills!");
            deade.sendMessage("You now have " + deaths + " deaths!");

        }

    }
}

非常感谢大家! :)

问题在于，每次一个玩家杀死另一个玩家时，您都会增加相同的变量。要解决此问题，您应该为每个玩家使用不同的变量，例如 "kills.playerUUIDHere" 和 "deaths.playerUUIDHere"。

获取玩家的UUID ，您可以使用player.getUniqueId() ，然后获取 UUID 的 String 表示形式，您可以使用 uuid.toString() 。因此，您可以执行以下操作来更改玩家的击杀数:

String uuid = player.getUniqueId().toString();

int kills = kdc.getConfig().getInt("playerkills." + uuid);
kdc.getConfig().set("playerkills." + uuid, kills += 1);

相同的逻辑可用于死亡，因此，您可以在 playerKillsPlayer() 方法中使用类似的内容:

@EventHandler
public void playerKillsPlayer(EntityDeathEvent e) {
    Entity dead = e.getEntity();
    Entity killer = e.getEntity().getKiller();

    if(killer instanceof Player && dead instanceof Player){
        String killerUUID = ((Player) killer).getUniqueId().toString();
        String deadUUID = ((Player) dead).getUniqueId().toString();

        int kills = kdc.getConfig().getInt("playerkills." + killerUUID);
        int deaths = kdc.getConfig().getInt("playerdeaths." + deadUUID);
        kdc.getConfig().set("playerkills." + killerUUID + , kills += 1);
        kdc.getConfig().set("playerdeaths." + deadUUID, deaths += 1);


        killer.sendMessage("You now have " + kills + " kills!");
        dead.sendMessage("You now have " + deaths + " deaths!");
    }
}
