Do you Guys have any Idea how to fix this one? Like I am just starting at developing of Plugins and I have no Clue how to fix this Error.

Also sorry for my bad English.

@Wibias
Be sure the path for your main class in your plugin.yml is correct.

 

@Cheesepro
My Main Class is named "main.java" and in my plugin.yml its named "main: me.wibias.main.main". I dont see the Problem at all?

 

What's your package name?

 

My Package Name is me.wibias.main!

 

@Wibias Have you ever heard of the Java naming conventions?

Anyway, if that is truth then you are not exporting your plugin right and the JAR is missing the class?

 

Wow. Just ignore this Thread. But now I am getting this Error when i die.. :s

Here is my Code for that:

Code:

package me.wibias.main;

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 PlayerDeath implements Listener{

    @EventHandler
    public void onPlayerDeath(PlayerDeathEvent event) {
        Player player = ((Player) event).getPlayer();
        event.setDeathMessage(player.getDisplayName() + ChatColor.RED + "ist einen qualvollen Tod gestorben!");
    }
}

@Wibias src

 

I am not sure what you mean with "src" but I posted my Code. I guess that is all what u need right?

 

@Wibias
Caused by: java.lang.ClassCastException: org.bukkit.event.entity.PlayerDeathEvent cannot be cast to org.bukkit.entity.Player

 

@Konato_K

I am kinda new to Java so I dont have any Clue what it means. Could u explain it to me please? And how can I fix that?

 

Moved to Bukkit Alternates.

 

Player player = ((Player) event).getPlayer();
um. I think u should learn java. Im just gonna explain this. event is a PlayerDeathEvent which cannot be casted to Player at all. It extends PlayerEvent and stuff. event.getPlayer() is a HumanEntity that can be casted to Player.
Player player = (Player) event.getPlayer();

 

@Wibias I suggest using google then

 

Java is case sensitive
