Scheduled Event

This is my first time using a delayed task... I tried using the wiki, but the example given no longer works. I searched around this forum, and came up with something which gave me no errors, and I was hoping it would work.

Well, it doesn't. I wasn't really sure where to put it, so that might actually be the problem.

If you could point out what I did wrong, that'd be great. Thanks!

Code:

    HashMap<Player, Boolean> invincible = new HashMap<Player, Boolean>();
 
    @EventHandler
    public void onPlayerInteractEvent(PlayerInteractEvent event) {
        final Player p = event.getPlayer();
        if (p.getItemInHand().getType().equals(Material.SPIDER_EYE)) {
            if (event.getAction().equals(Action.LEFT_CLICK_AIR) || event.getAction().equals(Action.LEFT_CLICK_BLOCK)) {
                p.getInventory().remove(new ItemStack(Material.SPIDER_EYE, 1));
                invincible.put(p, true);
                p.sendMessage("Invincibility enabled!");
 
            }
        }
     
        Bukkit.getScheduler().scheduleSyncDelayedTask((Plugin) this, new Runnable() {
            public void run() {
                invincible.remove(p);
                p.sendMessage("No more invincibility");
            }
        }, 100L);
    }

 

I'm guessing that wasn't your plugins main class? Because you need to use the one that extends JavaPlugin, not "(Plugin) this". And use a set instead of a map.

 

Aah, ok... It works!

Why should I use a set in this case?

Thanks!

 

Cause a set has two states:
- Something in it
and
- Something not in it
In your event you set it: set.add(key) and in the runnable you remove it: set.remove(key) and to get a true/false case you simply do if(set.contains(key)).
So no need to waste memory with a boolean map.
