Hi there. Im making a game called Adventure World, and this is the basic idea of it. You complete obbies/courses to unlock new courses. But in order to unlock those courses, you need to collect coins and get good completion times. I have been scripting for more than a year and need some help.
Right now im trying to create a stop watch timer. I know a little bit on how to use the tick function, but I really need some guidance on how to create this. Im also trying to learn about string converting (string.sub, string. format, ect.).
I have made some of the script(BELOW) and I have tried looking up how to create a stopwatch timer, but its not what im looking for or its a little to confusing.
-- Timer Looks like this: 00:00.00
local function displayTime()
local text = script.Parent.Text
local milliseconds = -- This is what I need help with
local seconds = --This is what I need help with
local minutes = --This is what I need help with
Text = (minutes.. ":" .. seconds.. "." ..milliseconds)
end
while timeIsRunning == true do -- timeIsRunning is a made up bool value I just made up, and is set to true when players click the start button. But I don't need help with that
wait()
displayTime()
end
So basically I just need help with the milliseconds, seconds, and minutes part of this script. Please tell me if there is a better way to do this.
First off, the text won’t even update with this - you’re assigning a variable to the current text and when you change that variable, it’ll update the variable and not the text
For displaying the time, you can get the time difference of two ticks: the initial (starting) tick, and the current. tick returns the number of seconds elapsed from the UNIX epoch (January 1, 1970) based on the computer’s time. Unlike os.time, tick returns exactly the number of seconds elapsed:
local function displayTime(diff)
local label = script.Parent
local milliseconds = ("%.3f"):format(tostring((diff % 1) * 1000))
local seconds = diff % 60
local minutes = math.floor(diff / 60) % 60
label.Text = (minutes.. ":" .. seconds.. "." ..milliseconds)
end
local t = tick()
while timeIsRunning do
wait()
displayTime(tick() - t)
end
while wait(0.001) do
miliseconds = miliseconds + 1
if miliseconds == 1000 then
seconds = seconds + 1
miliseconds = 0
end
if seconds == 60 then
minutes = minutes + 1
seconds = 0
end
end
local function displayTime(diff)
local label = script.Parent
local milliseconds = ("%.3s"):format(tostring((diff % 1) * 1000))
local seconds = math.floor(diff % 60)
local minutes = math.floor(diff / 60) % 60
if seconds < 10 then
seconds = "0" .. tostring(seconds)
end
label.Text = (minutes.. ":" .. seconds.. "." ..milliseconds)
end
@DatMADBuilder One thing to note: wait’s minimum wait time is 0.03 seconds. Also, don’t use wait as a condition for a while loop
Trying to count iterations in a loop for timing will never be the best option. The minimum wait time is unlikely to be the same on very CPU-intensive games.
To get around these issues, you could at least use the first return value of wait(), which is the actual time yielded. Unfortunately, just adding that time to a counter might reduce the accuracy of your timing.
The most accurate solution is to use tick() to calculate the elapsed time since the start of the timer.
special thanks to @Raretendoblox for almost making my reply pointless while I was still typing
one tiny problem: RobloxScreenShot20200428_154035177|690x304
In this picture I spawned right by the finished line to stop the time.
It shows a decimal after milliseconds. How would I fix this? I also got rid of the thousandths place in the milliseconds cause I don’t think I need that part. Either way though it will still show the decimal.
local function displayTime(diff)
local seconds = string.format("%05.2f", diff % 60)
local minutes = math.floor(diff / 60) % 60
if minutes < 10 then -- if the time is greater than 10 minutes, then ...
timerGui.Text = "0".. minutes .. ":" .. seconds
else -- if its not greater
timerGui.Text = minutes .. ":" .. seconds
end
end
local t = os.clock()
local timer
local function timerFunction()
local timePassed = os.clock() - t
if timePassed > 900 or isFinished then --if the time is greater than 15 minutes or finsihed
timer:Disconnect() --stop timer
endEvent:FireServer(game.Players.LocalPlayer)
return
end
displayTime(timePassed) -- display the time
end
timer = runService.Heartbeat:Connect(timerFunction) -- this timer runs on runservice
end
I don’t have a clear definition for os.clock(), but i think its similar to tick(). Here is the definiton on the hub:
os.clock is the amount of CPU time used by Lua in seconds.
RunService is mostly used for time managing scripts. It has an event called Heartbeat, which runs, or is fired, at every frame(fps). So if the game is running at 60fps(frames per second), RunService.Heartbeat will run 60 times.
Again, sorry for the late response, and these are great questions. Before, I was a bit confused on how run service worked too. If you have anymore questions, I will gladly answer them.
