on damage:
    if {hitted::%victim%} is not true:
        set {hitted::%victim%} to true
        set {hitted::cooldown::%victim%} to 30
        while {hitted::cooldown::%victim%} > 0:
            wait 1 second
            remove 1 from {hitted::cooldown::%victim%}
            if {hitted::cooldown::%victim%} <= 0:
                stop loop
        
        if {hitted::%victim%} is true:
            set {hitted::%victim%} to false
            send "&aYou can go spawn now!" to victim
        
on load:
    loop {hitted::*}:
        delete {hitted::%loop-index%}
        delete {hitted::cooldown::%player%}

on region enter:
    if "%event-region%" contains "REGIONNAME":
        if {hitted::%player%} is true:
            cancel event
            send "&c&l(!) &r&cYou need to wait &4{hitted::cooldown::%player%} &cseconds to go spawn!"
