Help with the awesome coolness.

Hey Guys,
i was just wondering if there was a way to check if there was no one in the radius of the nearbyPlayers.... Like if no player is in range, it sends a message to the player saying so.

Code:

Code:java

        @EventHandler
        public void onPlayerFreeze(PlayerInteractEvent e){
            Player p = e.getPlayer();
            List<Entity> nearbyEntities = p.getNearbyEntities(10, 10, 10);
            ArrayList<Player> nearbyPlayers = new ArrayList<Player>();
                    if ((e.getAction() == Action.LEFT_CLICK_BLOCK && e.getPlayer().getItemInHand().getType()
                            == Material.SNOW_BLOCK
                            || e.getAction() == Action.LEFT_CLICK_AIR && e.getPlayer().getItemInHand().getType()
                            == Material.SNOW_BLOCK)){
 
                        int cooldownTime = 20; // Get number of seconds from wherever you want
                        if(snow.containsKey(p.getName())) {
                        long secondsLeft = ((snow.get(p.getName())/1000)+cooldownTime) - (System.currentTimeMillis()/1000);
                        if(secondsLeft>0) {
                // Still cooling down
                            p.sendMessage(ChatColor.RED + "Wait " + ChatColor.GOLD + secondsLeft + ChatColor.RED + " seconds to use this again!");
                            return;
                        }
                }
                // No cooldown found or cooldown has expired, save new cooldown
                        snow.put(p.getName(), System.currentTimeMillis());
 
                        p.getLocation().getWorld();
                            for (Entity e1 : nearbyEntities) {
                                if (e1 instanceof Player) {
                                    nearbyPlayers.add((Player) e1);
                            for (Player p1 : nearbyPlayers) {
                                p1.getLocation().getWorld();
                                Snow.add(p1.getName());
                                p1.sendMessage(ChatColor.GOLD + p.getName() + ChatColor.RED + " has frozen you!!");
 
 
                            }
                    }
                }
            }
        }

 

just use getNearbyEntities like you have been doing, check if the entity is a player, and if it is, send the player a message and break the for loop

A little more detail please?

Isn't "loop through get nearby entities" enough detail already?
