Solved Can someone check for errors?

So I'm making a plugin which detects when a player gets an achievement, and it gives them an item randomly from a list I'm making. I have exported it to my server, but I'm not getting any achievements or messages. This might be with my code, or it might be with my server.

My Main Class:

Code:

package me.themedieval;

import org.bukkit.plugin.java.JavaPlugin;

public class Medfre1 extends JavaPlugin{
  
    public void onEnable() {
        new EventListener(this);
    }
  
    public void onDisable(){
      
    }


}

My Listener Class:

Code:

package me.themedieval;

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerAchievementAwardedEvent;

public class EventListener implements Listener{
    public EventListener(Medfre1 plugin) {
        plugin.getServer().getPluginManager().registerEvents(this, plugin);
    }
    @EventHandler
    public void aListener(PlayerAchievementAwardedEvent event) {
        Player player = event.getPlayer();
        double number = Math.random();
        if(number <= 0.34) {
            player.sendMessage(ChatColor.GREEN + "You won a prize for completing an achievement!");
        } else if(number <= 0.67) {
            player.sendMessage(ChatColor.RED + "You won a prize for completing an achievement!");
          
        } else {
            player.sendMessage(ChatColor.BLUE + "You won a prize for completing an achievement!");
        }
    }
}

So far I have made it only send messages as a test, however I don't see any messages.

I do have achievement announcement on in my server but it doesn't seem to work, and I need to delete player data but when I deleted userdata I still have all my gear/perms.

 

@Brevoort
It doesn't look like you registered your events correctly. Try the registerEvents() method in onEnable?

 

How would I use this method?

 

@Brevoort
Bukkit#getPluginManager()

You should be able to handle it from there?

 

One more question!
How could I make it so that when it detects the achievement, instead of just sending a message, it runs a command. (I know I could just make it give the player an item, however I want to make it run a command like /pay player 1000 or something like that.

 

Code:

dispatchCommand(CommandSender sender, String commandLine);

 

I tried using this but it gives me errors and asks me to create constants for all of those.

 

Code:

Bukkit.dispatchcommand(Bukkit.getconsolesender(), "yourcommand")

example below,

Bukkit.dispatchcommand(Bukkit.getconsolesender(), "say hello world!")


will execute '/say hello world!' from console 

 

Thanks this seems to work however using
Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "give " + player + " minecraft:diamond 1");
results in the console saying "player not found."

I'm defining player as Player player = event.getPlayer();

 

That's because you're getting the player itself not the players name use player.getName()

 

thanks
