how long you want the cooldown to be?

 

or this:

Code (Skript):

1. on command:
2.     if {Command::%player%} is "%full command%":
3.         send "You spamming this commands!"
4.         cancel event
5.     else:
6.         set {Command::%player%} to "%full command%"

else cooldown:

Code (Skript):

1. on command:
2.     if {CoolDown::%player%} is not set:
3.         set {CoolDown::%player%} to now
4.         stop
5.     if difference between {CoolDown::%player%} and now is less than 5 seconds:#<= here changeable
6.         send "Stop spamming commands."
7.         cancel event
8.     else:
9.         set {CoolDown::%player%} to now

 

Code (Skript):

1. on command:
2.   if player has permission "skript.command.waiting.bypass":
3.     stop
4.   if {lastusedcommand::%player%} is set:
5.     set {_timespan} to difference between {lastusedcommand.%player%} and now
6.     if {_timespan} is less than 1 minute:
7.       cancel event.
8.       message "You can't use commands so fast!"
9.       stop
10.   set {lastusedcommand::%player%} to now

 

I want to use this type of blocking spam:

on command:
if {Command::%player%} is "%full command%":
send "You spamming this commands!"
cancel event
else:
set {Command::%player%} to "%full command%"

But I want to block the spam on the third try to write same command.
So the players would be able to write same command only two times.
