#

What happens instead?

cerulean warren Oct 30, 2022, 2:09 PM

#

nothing

#

nothing is written to console

weak abyss Oct 30, 2022, 2:09 PM

#

Is your listener registered?

cerulean warren Oct 30, 2022, 2:09 PM

#

not sure what that means xD

weak abyss Oct 30, 2022, 2:09 PM

#

Do you have the main class on you?

cerulean warren Oct 30, 2022, 2:10 PM

#

yeah

#

package wands.wands;

import org.bukkit.Bukkit;
import org.bukkit.event.Listener;
import org.bukkit.plugin.Plugin;
import org.bukkit.plugin.java.JavaPlugin;

public final class Wands extends JavaPlugin {

@Override
public void onEnable() {
    registerEvents(this,new WandOfSouls(this));
}

@Override
public void onDisable() {
    // Plugin shutdown logic
}

public static void registerEvents(final Plugin plugin, final Listener... listeners) {
    for(final Listener listener : listeners) {
        Bukkit.getServer().getPluginManager().registerEvents(listener, plugin);
    }
}

}

#

So in order for this other listener class to work ("implements Listener" at the top)

#

Okay so you do register it

cerulean warren Oct 30, 2022, 2:11 PM

#

i tried adding messages to the entity if it s a plyer and to the damager at each step

#

but not a single message appeared

#

so it probably isnt running the event

weak abyss Oct 30, 2022, 2:11 PM

#

Do you get any errors?

cerulean warren Oct 30, 2022, 2:11 PM

#

no

#

Oh I see it now

cerulean warren Oct 30, 2022, 2:12 PM

#

my friend joined and hit me

#

nothing went through

weak abyss Oct 30, 2022, 2:12 PM

#

Your hitEnemy method is missing an

@EventHandler

#

at the top

cerulean warren Oct 30, 2022, 2:12 PM

#

when does evenhandler need to be used

#

and when does override need to be used

weak abyss Oct 30, 2022, 2:13 PM

#

@EventHandler is an annotation
https://docs.oracle.com/javase/tutorial/java/annotations/

that is provided by the Spigot api. It is used so that the API can recognize which of your methods listen to events

Lesson: Annotations (The Java™ Tutorials > Learning the Java Langua...

This beginner Java tutorial describes fundamentals of programming in the Java programming language

#

The @Override is a java thingy that is related to OOP and overriding the methods of parent classes
