Yields for a time in seconds and returns the time that passed. A negative time is an error, and so is a wait where the code cannot yield.

task.sleep(1)

Use it forpausing between rounds, or counting down the seconds before a race starts.

Runs a function in a new thread now, with the arguments.

task.spawn(function() print("now") end)

Use it forstarting a looping light show that runs on its own, without stopping the rest of your script.

Runs a function in a new thread later in this tick.

task.defer(function() print("later this tick") end)

Use it forrunning a follow-up step later in the same tick, after the rest of your setup code.

Runs a function in a new thread after a time in seconds.

task.delay(3, function() print("3 seconds later") end)

Use it forclosing a door a few seconds after it opens, or anything else that should happen a little later.

Runs a function every interval of seconds, the first time one interval after the call. Missed intervals are skipped.

task.every(5, function() print("tick") end)

Use it forgiving every player tokens each minute, or sending in a new enemy wave on a steady timer.

Stops a thread before it runs again.

local timer = task.delay(10, function() print("time is up") end) task.cancel(timer)

Use it forstopping a round timer early when everyone has finished, so it does not go off.

The script clock in seconds. time.now is the wall clock instead.

local started = task.now()

Use it fortiming how long a player takes to finish an obby, by comparing the clock at the start and the end.
