I need help [URGENT]

Well, my code is everything "right" is not giving error in eclipse, or the console, all API'S are installed, and the event that I created does not work .. could you help me? Have asked for help to several of my friends and none knows the error.

Well, the usefulness of the plugin works when the player steps into the emerald block and he wins an unbeaten record (against falls, hits, etc.) for 30 seconds

Code:

@EventHandler
public void onDamageEvent(EntityDamageEvent event) {
        if(!(event.getEntity() instanceof Player)) return;
        Player p = (Player) event.getEntity();
        if (plugin.invi.contains(p.getName())) {
          event.setCancelled(true);
          return;
      }
    }
 
@EventHandler
public void cu(PlayerMoveEvent event) {
  final Player player = event.getPlayer();
 
  if (!event.getFrom().getBlock().getLocation()
    .equals(event.getTo().getBlock().getLocation()))
    return;
  Block block = player.getLocation().getBlock()
    .getRelative(BlockFace.DOWN);
  if ((block.getType() == Material.EMERALD_BLOCK) &&
    (!plugin.invi.contains(player.getName()))) {
    plugin.invic.add(player.getName());
    player.getPlayer().playSound(player.getLocation(), Sound.ENDERMAN_TELEPORT, 10.0F, 0.0F);
    Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
        public void run() {
          plugin.invic.remove(player.getName());
          player.sendMessage("§6§lVocê perdeu sua Invencibilidade!");
        }
    }
  , 800L);
  }
}
}

 

Code:java

new BukkitRunnable() {
public void run() {
// method here - metodo run aqui
}
}.runTaskLater(plugin, 800);

Vai ser mais eficiente que getScheduler().schedule

 

Code:

if (!event.getFrom().getBlock().getLocation() .equals(event.getTo().getBlock().getLocation())) return;

Is your error, it will "return;" if the from location is not the same as the to location. Remove the ! and it should work.
