How to add a cooldown of 15 seconds

[varboosted]

on shoot:
    shooter is player
    "%projectile%" is "arrow"
    name of tool of shooter is "&cSpam!"
    {nospam::%shooter%} is not set
    set {nospam::%shooter%} to true
    wait a tick
    loop 2 times:
        shooter has an arrow
        make shooter shoot a arrow
        wait a tick
    delete {nospam::%shooter%}

How can I make a cooldown every time after he shoots?

maybe add a wait 15 seconds after it shoots an arrow :/

maybe add a wait 15 seconds after it shoots an arrow :/

I didn't mean this, I mean that there will be cooldown each time it shoot 3 arrows

options:
  cooldown: 5 # in seconds

on shoot:
  if {arrowsshot::%shooter's uuid%} is more than or equal to 3:
    if {cooldown::%shooter's uuid%} is true:
      stop
    else:
      set {cooldown::%shooter's uuid%} to true
      wait {@cooldown} seconds
      clear {cooldown::%shooter's uuid%}
    cancel event
  else:
    add 1 to {arrowsshot:%shooter's uuid%}

This should work depending on what you want.
