Assigning information to players

[whole jungle]

Let me just type this out

[lucid bluff]

ok

[whole jungle]

public class HardModeEvents implements Listener {
    boolean already_Informed = false;

    @EventHandler
    public void onMove(PlayerMoveEvent event) {
        Player player = event.getPlayer();
        if (player.getLocation().getBlock().getBiome() == Biome.ICE_SPIKES) {
            player.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 1, 2));
            if (already_Informed == false) {
                player.sendMessage(ChatColor.BLUE + "It's getting cold here");
                already_Informed = true;
            }
        } else {
            already_Informed = false;
        }

    }
}

I'm just wondering how I would assign the boolean per player and not global

This may be basic java knowledge that I'm lacking

you know what time it is?

HASHMAP TIME

nvm, you can just make a set

make a set of informed players (add the player to that set eevrytime u inform them)

now use set.contains(player) to check if they have been informed

//sets are faster when it comes to checking if they contain x element so use sets over lists

I'll try it
