Solved Check if Zombies are dead every X seconds

Hello there beautiful people, first and foremost if you're reading this, thank you for spending the time.

Now into the issue.

Precursor:

I have a zombie spawn on round one.

Problem:

On round one, one zombie spawns, and I need to check if it is dead, so I can move to the next round. I spawn this zombie using:

Zombie z = ( Zombie ) world.spawnEntity(spawnLoc, EntityType.ZOMBIE);

Now I want to check if this zombie has died every X number of seconds.


However I get illegalmoniterexception.

I'm using a bukkit runnable to do these checks my class is setup like this:

Code:

public class Rounds extends BukkitRunnable {


private final JavaPlugin plugin;
private static int round; 
 private static Utils util = new Utils(); 
   public Rounds(Zombies plugin){
    this.plugin = plugin;round=0;
  }


@Overridepublic void run () {
    util.broadcast("Round: " + round); 
    while (true) {
       World w = Bukkit.getWorld("world");
       Location spawnLoc = new Location(w, 11.0, 101.0 + 2., 6.0);
        Zombie zomb = (Zombie) w.spawnEntity(spawnLoc, EntityType.ZOMBIE); 
        while (zomb.isDead() == false) {
                 if (zomb.isDead()) {
                   round++; 
                   } else {
                         try {
                                wait(5000);
                         } catch (Exception e) {
                             util.broadcast("ERROR: " + e);}
                         }
                   }
             }

         }

I have read scheuled programming guide for threads, however it doesn't click with me for some reason. Could someone explain this to me?

 

I recommend you use a bukkit repeating scheduler instead of a while loop. It seems to me that the wait(5000) is causing the error.

 

Or use the EntityDeathEvent with @EventHandler and check if the entity is that entity (maybe by location or by naming it something unique).
