[Help]Need delay

Code:

    @EventHandler
    public void spawnerblock(BlockPlaceEvent event){
        Material block = event.getBlock().getType();
        Player player = event.getPlayer();
        World world = player.getWorld();
        Location location = event.getBlock().getLocation();
        for (Material spawnzombie : spawner) {
            if(spawnzombie == block) {
                do {
                world.spawnEntity(location, EntityType.ZOMBIE);
                //need delay here
                } while(true);
               
}

Tried Thread.sleep(), etc but it doesn't seem to work!

How can I add delay?

 

Use runnables:

Code:

    new BukkitRunnable()
        {
            int count = 10;
            public void run()
            {
                // Spawn zombie
                count--;
                if (count == 0)
                    cancel();
            }
        }.runTaskTimer(plugin, delay, interval-between-spawnings);

Using do/while loops for delays don't work, and Thread.sleep() will sleep the main thread, causing the whole server to freeze up and players to be disconnected

 

dajako Lol! NEVER use Thread.sleep();!

 

Ok, I think I understand how to use it. I'll give it a try.
Thanks

Ah, may sounds nooby but I have no idea where I'd but this. Do I have to chance the event or what?
