How to do a Cooldown?

[XP_Static]

I want to make an "if" function have a cooldown time before it can execute again, but i don't have an idea how i could do this.

example code

function GM:PlayerHurt(victim, attacker)
if victim:Health() <30 then
victim:EmitSound("hurt.wav")
end
end

This code would play the sound every time the player get hit when his health is below 30. How can i make it have a cooldown of x seconds before it can play the sound again??

Try something like this:

function GM:PlayerHurt(victim, attacker)
    if ( victim:Health() < 30 and CurTime() - ( victim.previousHurtSoundTime or 0 ) >= 2 ) then -- once every 2 seconds
        victim:EmitSound("hurt.wav")
        victim.previousHurtSoundTime = CurTime()
    end
end

on server sartup this code causes an lua error in my test.
TEST [lua/autorun/weaponremover.lua][lua/autorun/codhealthsys.lua]

[ERROR] lua/autorun/codhealthsys.lua:75: 'then' expected near ')'

because i don't understand this part of the code i can't find the mistake myself.

I've just tried this code and it works as expected. You made an error while copy/pasting, or the error is somewhere else above this code. Post the first 75 lines of your script.
