How to broadcast a message when reached player limit

Hello, I've been trying to make a plugin when there is a certain amount of players online a message will broadcast but I can't seem to get it to work. Can anyone help me? :c

Code:java

package craftedevil.plugin;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scheduler.BukkitRunnable;
 
public class PlayerCountDown extends JavaPlugin implements Listener {
 
    int countdown;
    int id;
 
    @EventHandler
    public void OnPlayerJoinEvent(PlayerJoinEvent e) {
        if(Bukkit.getServer().getOnlinePlayers().length >= 1);
            getServer().broadcastMessage(ChatColor.DARK_GREEN + "" + ChatColor.BOLD + "[" + ChatColor.YELLOW + "Plugin" + ChatColor.DARK_GREEN + "" + ChatColor.BOLD + "]" + ChatColor.GRAY + "Lobby mode will end in 30 seconds.");
            if(Bukkit.getServer().getOnlinePlayers().length >= 1);
            getServer().broadcastMessage(ChatColor.GREEN + "Started");
                countdown = 10;
                id = getServer().getScheduler().scheduleSyncRepeatingTask(this, new BukkitRunnable() {
                    @Override
                public void run() {
                        getServer().broadcastMessage(ChatColor.DARK_GREEN + "" + ChatColor.BOLD + "[" + ChatColor.YELLOW + "Plugin" + ChatColor.DARK_GREEN + "" + ChatColor.BOLD + "]" + ChatColor.DARK_GRAY + "[" + countdown + ChatColor.DARK_GRAY + "]");
                        if(countdown == 0) {
                            Bukkit.getScheduler().cancelTask(id);
                            getServer().broadcastMessage(ChatColor.GREEN + ".o.");
                        }
                        countdown--;
                    }
                }, 0L, 20L);
            }
 
        }

 

Something like this?

Code:java

 
@EventHandler
public void onJoin(PlayerJoinEvent event){
    switch(Bukkit.getServer().getOnlinePlayers().length){
 
    case 10: Bukkit.broadcastMessage("10 Players are online! Wow!");
    break;
 
    case 11: Bukkit.broadcastMessage("11 Players are online! One More<3");
    break;
    }
}

case 10: means 10 players. case 1: would mean 1 player.

 

Dako Didn't work :c

 

Crafted Evil Because your events aren't registered.....

Code:java

public void onEnable() {
Bukkit.getPluginManager().registerEvents(this, this);
}

 

sgavster Derp slurp, forgot to do that >.>

 

saw this now

 

Dako Been editing it and it gives me the error: "Could not pass event PlayerJoinEvent to Plugin v1"
My code so far:

after a case is ended you have to write break; or return;(ends void)

Example

Code:java

switch(Bukkit.getServer().getOnlinePlayers().length){
        case 1:    getServer().broadcastMessage(ChatColor.GREEN + "Started");
        id = getServer().getScheduler().scheduleSyncRepeatingTask(this, new BukkitRunnable() {
            @Override
        public void run() {
                getServer().broadcastMessage(ChatColor.GOLD + "Time: " + countdown);
                if(countdown == 0) {
                    Bukkit.getScheduler().cancelTask(id);
                }
                countdown--;
            }
        }, 0L, 20L);
        break;
 
        case 2: .....
                break;
    }

 

Dako Still dosn't work, heres a stack trace from when I log in to the server

You can just use if if you only have a condition, switch is normally used when you have a bunch of them

 

You're talking about a record? When a new record of people are online then it broadcasts to server and put new record to config or somewhere?

 

No, when a certain amount of people are online it should broadcast a message.

 

and amount of certain people online should be in config?

 

BenRush No, when the desired player number is reached a message is broadcasted and a countdown to display another message begins.

Code:

switch(Bukkit.getServer().getOnlinePlayers().length){
        case 1:    getServer().broadcastMessage(ChatColor.GREEN + "Started");

 

maybe something like this?

Code:java

    @EventHandler
    public void onJoin(PlayerJoinEvent event){
        int num= 0;
        for(int i = 0; i < Bukkit.getServer().getOnlinePlayers().length; i++) {
        num= i;
        }
        if(num == 1){
            getServer().broadcastMessage("GOOD");
        }
    }

 

That for loop is completely unnecessary just do if(getServer().getOnlinePlayers().length() == (your number){
//do something
}

Your error is NPE, its about this line:

Code:java

case 1:    getServer().broadcastMessage(ChatColor.GREEN + "Started");

try using PhilipsNostrum example.

 

Bump, still dosen't work.
