How do i add a cooldown?

[blazing sparrow]

what is {s}

oh ok

if item cooldown of event-item for player = 0 seconds: you can check if the tool doesn't already have a cooldown

set item cooldown of player's offhand tool for player to 20 seconds then if that condition passes you can set the cooldown

Or you can just use metadata/variables, depends on which you want

if you want the cooldown to be visual, item cooldown
