Delays and Cooldowns
A delay (or cooldown) is a way to make an event only trigger if a certain amount of time has passed since its last occurrence.
Creating an event cooldown
An event cooldown can be created in several ways, and it is made by setting a condition based on time
function myFunc() if funcNotOnCooldown then -- Do stuff end end
CurTime is a useful tool for setting a delay for an event. The function returns the uptime of the server in seconds, which means we can use it to keep track of time elapsed by saving the returned value, then calling it again.
Here's an example of a cooldown made using CurTime
local delay = 2 local lastOccurance = -delay -- Ensure the first trigger attempt will work local function myFunc() local timeElapsed = CurTime() - lastOccurance if timeElapsed < delay then -- If the time elapsed since the last occurance is less than 2 seconds print( "The event is on cooldown and has not been triggered" ) print( "Please wait another " .. math.Round( delay - timeElapsed ) .. " second(s)" ) else print( "The event has been triggered!" ) lastOccurance = CurTime() end end
If your event isn't related to in-game events; consider using RealTime instead, which will always be synced to real-world time rather than server time
In the above example, we use CurTime to tell when the last event had occured. Instead, we could use it to determine when the next event should occur
local delay = 5 local nextOccurance = 0 local function myFunc() local timeLeft = nextOccurance - CurTime() if timeLeft < 0 then -- If the time has passed the nextOccurance time print( "The event has been triggered!" ) nextOccurance = CurTime() + delay else print( "The event is on cooldown and has not been triggered" ) print( "Please wait " .. math.Round( timeLeft ) .. " second(s)" ) end end )
Another method of setting a delay is using the timer library.
local delay = 2 local shouldOccur = true local function myFunc() if shouldOccur then print( "The event has been triggered!" ) shouldOccur = false timer.Simple( delay, function() shouldOccur = true end ) else print( "The event is still on cooldown" ) end end
