Jak dodać cooldown w skrypcie

[Mleczyk1]

Ostatnio  pisalem sobie skrypt i wpadlem na taki pomysl 

variables:
    {czas.%player} = 5
    {odl.%player%} = false
command /umka:
  trigger:
    give 1 Diamond Horse Armor of fortune 10 named "&6Umiejetnosc" to player
    send "&eDostales umke!"
on right click with Diamond Horse Armor:
  if name of player's tool is "&6Umiejetnosc":
    if difference between {Czlowiek1::%player%::lastuse} and now is smaller than 5 seconds:
    send "&c%difference between {Czlowiek1::%player%::lastuse} and now% sekund do odnowienia!"
    stop
On rightclick:
    if player is holding diamond horse armor named "&6Umiejetnosc":
        if player has permission "czlowiek.1":
            if difference between {Czlowiek1::%player%::lastuse} and now is smaller than 5 seconds:
                set {odl.%player%} to true
                send "&c%difference between {Czlowiek1::%player%::lastuse} and now% sekund do odnowienia!"
                stop
            send "&aUżyłeś umiejetnosci!"
            set {Czlowiek1::%player%::lastuse} to now
                                shoot a fireball from player
            
Every 1 second:
    loop all players:
        if {odl.%loop-player%} is true:
            if {czas.%loop-player%} is bigger than 0:
                remove 1 from {czas.%loop-player%}
            else:
                add 5 to {czas.%loop-player%}
                set {odl.%loop-player%} to false
