Runnables...

Alright so my event here:

Code:java

public static void spawnFrost(Player player) {
   boolean check = plugin.getConfig().getBoolean(player.getName() + ".ForstMount");
   if (!check) {
plugin.getConfig().set(plugin.getName() + ".FrostMount", true);
plugin.saveFile();
player.sendMessage(ChatColor.GREEN + "Mount unlocked! Click on it again to use!");
   } else if (check) {
   org.bukkit.entity.Horse horse = (org.bukkit.entity.Horse) Bukkit.getWorld("world").spawnEntity(player.getLocation(), EntityType.HORSE);
   horse.setCustomName(ChatColor.AQUA + "" + player.getName() + "'s Horse");
   horse.setCustomNameVisible(true);
   horse.setAdult();
   horse.setAgeLock(true);
   horse.setColor(Color.WHITE);
   horse.setStyle(Style.WHITE);
   horse.setVariant(Variant.HORSE);
   horse.setOwner(player);
horse.setMaxDomestication(1);
   player.sendMessage(ChatColor.GREEN + "Mount Spawned");
   particles.add((Player) horse);
   }
}

As you can see at the end it add the entity to the Hashmap. Now I want to make a runnable like so:

Code:java

    public static void frostparticles() {
        new Runnable() {
 
            @Override
            public void run() {
                if (particles.contains();
 
            }
        };

I basically want to see if it contains the horse so It can run the runnable. I am briefly stuck on this part please help.

 

VictoryShot Your casting Horse to Player?

 

Only aviable option.

 

VictoryShot Change the lists generic type?

 

VictoryShot It appears you have a typo in your "check" boolean. I would imagine it'd get quite frustrating if you didn't catch it now, then began testing the plugin and got some random error.

Code:java

getBoolean(player.getName() + ".ForstMount")// "Forst", not "Frost"

Edit: I finished reading your code and went and did some Bukkit JavaDoc research (which I do when I'm reading unfamiliar Bukkit plugin code), and I'm not sure why you would have any reason to cast your horse to Player. If your HashMap is using either Horse or Entity, I wouldn't think you'd need to cast.

 

No clue

Well change it.

 

If you have no clue on what that generic type would be, I believe he means you should change your list's type--which is apparently Player at the current moment--to Entity. Entity is the generic type of Player, Horse, Villager, and, well, all other entities.
If you happen to be clueless about the definition of "generic": Google "define generic"
