How can I use RunService.Heartbeat to make a timer?
Hello. I've seen some free timer models and when I look through their scripts, those really detailed timers with 3 decimal points uses RunService.Heartbeat. I'm currently making a timer but its accuracy is only to 1 decimal point, as if its above 1 decimal point the timer would be inaccurate.
1 | while true do |
2 | wait(0.1) |
3 | Time.Value = Time.Value + 0.1 |
4 | end |
I know this is not the most effective method. So is Heartbeat more effective and if so how can I use it to increase my timer accuracy to 3 decimal points?
Thanks for your time and I appreciate all help!

I'm not sure if Heartbeat is more effective or not than the while loop, but this is how I would do it:
01 | local runService = game:GetService('RunService') |
02 |
03 | local maxTime = 1 -- when timer should end |
04 | local currentTime = maxTime |
05 |
06 | local function onFinished () |
07 | print('TIMER FINISHED') |
08 | end |
09 |
10 | runService.Heartbeat:Connect(function(dt) |
11 | currentTime -= dt -- dt is delta time, which is the time between each frame |
12 |
13 | if currentTime < 0 then |
14 | onFinished() |
15 | currentTime = maxTime -- resets the timer |
16 | end |
17 | end) |
Heartbeat is only for the client, but for the server you would need something else.
Instead, we can use tick(). If we look up Tick() it returns the number of seconds (including milliseconds) from the Unix Epoch. So we can make a more accurate timer for the server using the following code.
01 | local function startTimer (timeLength) |
02 | local startValue = tick() |
03 |
04 | while (startValue + timeLength) > tick() do |
05 | -- do nothing |
06 | wait(0.00001) |
07 | end |
08 |
09 | return |
10 | end |
The code above should be very accurate, and if you want it to be more accurate just decrease the wait() even more. But it would be very costly to do so. I am unsure of any better ways to make a timer, so correct me if I'm wrong.
EDIT: SORRY! My mistake, both would work on the server. Thanks to OfficerBrah for correcting me.
