package com.beastcraft3.wut;

import java.util.HashSet;
import java.util.UUID;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerQuitEvent;

public class Brawl implements Listener{
    
    private boolean isBrawlPlayable;
    private HashSet<UUID> players = new HashSet<UUID>();
    private Main main;
    
    
    @EventHandler
    public void onjoin(PlayerJoinEvent e){
        
        Player p = e.getPlayer();
        
        if(!players.contains(p.getUniqueId())){
            players.add(p.getUniqueId());
            
            p.sendMessage("Added... There is now: " + String.valueOf(players.size()) + " players online.");
            int players_online = main.getConfig().getInt("players_online");
            main.getConfig().set("players_online", players_online + 1);
            main.saveConfig();
            
            brawlIsPlayable(p);
            
        } else {
            
            p.sendMessage("Already inside. ***** wut?");
            
        }
        
    }
    
    @EventHandler
    public void onLeave(PlayerQuitEvent e){
        Player p = e.getPlayer();
        
        if(players.contains(p.getUniqueId())) {
            players.remove(p.getUniqueId());
            int players_online = Integer.valueOf(main.getConfig().getInt("players_online"));
            main.getConfig().set("players_online", players_online - 1);
            main.saveConfig();
        }
        
    }
    
    public void brawlIsPlayable(Player p){
        if(players.size() >= 300){
            
            setBrawlPlayable(true);
            p.sendMessage("Brawl is playable atm");
            
        } else {
            
            setBrawlPlayable(false);
            p.sendMessage("Brawl is not playable atm");
            
        }
    }
    


    public boolean isBrawlPlayable() {
        return isBrawlPlayable;
    }


    public void setBrawlPlayable(boolean isBrawlPlayable) {
        this.isBrawlPlayable = isBrawlPlayable;
    }
    
    

}

dunt complain, made it in like 5 min cuz bored

 

Yeah, no point having the hashset really when I store it in the config(incase of reload), and I didnt bother to register it since thats just a random class in a premade plugin and I dont actually want the plugin to run this class.

And I made it in like 5 min for a joke against brawl since its unplayable with a low playerbase at times
