Solved How to play a effect when a count down is going?

Hello, is there a way i can get all the player on the server and play a effect at their location but i only want the effect to play ever message the countdown gives out.
For example I want an effect/sound to be heard by everyone every time the Countdown says like "5 Minutes Left"

Here is my Countdown code:

Code:java

 
public void CountDown(){
       Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask((Plugin) this, new Runnable(){
           @Override
           public void run(){
               final int minutes = Count / 60;
               if (Count % 60 == 0 && Count > 60){
                   Bukkit.broadcastMessage(prefix + "THE WALL WILL FALL IN " + minutes + " MINUTES!");
               }
               else if (Count == 60){
                   Bukkit.broadcastMessage(prefix + "THE WALL WILL FALL IN " + minutes + " MINUTE!");
               }
               else if (Count == 30){
                   Bukkit.broadcastMessage(prefix + "THE WALL WILL FALL IN " + Count + " SECONDS!");
               }
               else if (Count == 15){
                   Bukkit.broadcastMessage(prefix + "THE WALL WILL FALL IN " + Count + " SECONDS!");
               }
               else if (Count < 11 && Count > 0){
                   Bukkit.broadcastMessage(prefix + "THE WALL WILL FALL IN " + Count + " SECONDS!");
               }
               else if (Count == 0){
 
               }
               Count--;
           }
       },0L, 20L);
   }
 

When i was doing research some people look like they tried to send a packet but that's not working for me.

 

Pseudo, real quick.

Code:

for player onlineplayer : bukkit.getOnlineplayersstuff {
    onlineplayer.playSound(onlinePlayer.getLocation(), sound st00f over here);
    onlinePlayer.getWorld().playEffect(onlinePlayer.getLocation(), effect st00f over here);
}

 

Rprrr Thanks So Much
