Cooldowns?

Can someone please explain to me how to add a cooldown to this

Code:

 @EventHandler
  public void onPlayerRightClickStrength(PlayerInteractEvent event)
  {

    Player player = event.getPlayer();

    if (player.hasPermission("specialabilities.superstrength"))
    {
      if (event.getAction() == Action.RIGHT_CLICK_AIR)
      {
        player.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 200, 1));
      }
    }
    return;

I tried this and go nothing

Code:

public void OnRightClickStength(PlayerInteractEvent event) {
      HashMap<String, Long> cooldowns = new HashMap<String, Long>();
    Player player = event.getPlayer();
   if(cooldowns.containsKey(event.getPlayer())){
       long secondsLeft = ((cooldowns.get(event.getPlayer())/1000)+cooldownTime) - (System.currentTimeMillis()/1000);
       if(secondsLeft>0){
           //still cooling down
           player.sendMessage("You can't use that ability for another " + secondsLeft + " seconds!");
    if (player.hasPermission("specialabilities.superstrength"))
    {
      if (event.getAction() == Action.RIGHT_CLICK_AIR)
      {
        player.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 200, 1));
      }
    }
    return;
  }
  }
  }

 

Code:

    private ArrayList<String> cooldown = new ArrayList<String>();
  
    @EventHandler
    public void onPlayerRightClickStrength(PlayerInteractEvent event) {
        final Player player = event.getPlayer();
      
        if(player.hasPermission("specialabilities.superstrength")) {
            if(event.getAction() == Action.RIGHT_CLICK_AIR) {
                if(!cooldown.contains(player.getUniqueId().toString())) {
                    cooldown.add(player.getUniqueId().toString());
                    player.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 200, 1));
                  
                    new BukkitRunnable() {

                        @Override
                        public void run() {
                            cooldown.remove(player.getUniqueId().toString());
                        }
                      
                    }.runTaskLater(plugin, 20L*seconds);
                } else {
                    player.sendMessage("Cooldown!");
                }
            }
        }
    }

- ArrayList
- Checking if ArrayList doesn't contain player UUID -> adding Cooldown, removing after some seconds (with BukkitRunnable)

 

The spoonfeeding be real >.>

@Calebizzthaman use a Bukkit Runnable https://hub.spigotmc.org/javadocs/spigot/org/bukkit/scheduler/BukkitRunnable.html
