How do i decrease an int value? And how do i keep repeating this until i want it to stop?

Asked 478 views2 answers

Hello!

I'm making an game with an countdown. I use an IntValue to showcase the value.

And via an gui i show that int value, creating an countdown, etc.

If you dont understand, basicly this.

while true do
	local epic = game.Workspace.TimeCycle.Time.Value -- this is temp here for testing

	script.Parent.Text = (epic)
end

but anyways, i wanna know, how can i subtract value from the int value?

(note, ive seen other posts, but iether i am actually stupid, or the script was specialized)

its hard to explain what i really want. but basicly


local count = script.Time.Value

count = "80"
wait(1)
count = "79"

-- etc

but then in a more efficient way.

the title says it all. Please dont bully me for this. Im new to coding.

Thanks in advance

You can't use strings in int values, also here is how you decrease it:

local count = script.Time--This is a mistake a lot of beginners do, when you set a variable for the .Value you can't change it, the variable is just set to the current value of the .Value

while true do--Sets up a loop
	wait(1)--Waits 1 before subtracting
	count.Value = count.Value - 1--Subtracts 1 from the count.Value, because you want it to equal to it's current value - 1
	
	if count.Value <= 0 then--Checks if it is less than or equal to 0, note that the less than is just a precaution incase something weird happens
		break--Breaks out of the loop
	end

	script.Parent.Text = tostring(count.Value)--Make sure to convert the number to a string before setting the value of any string to a number
end

--Now the count.Value should be equal to 0

Intvalues are always hard to wrap your head around at first, but it will make more sense as you use them more and more.

An alternative answer to firestarroblox123 is using for loops.

for loops play until it reaches a certain point.

An example:

for i = 30,1,-1 do
	script.Parent.Time.Value = i
	wait(1)
end

Basically, what it's saying is this:

From 30 to 1, subtract 1 from the 30 everytime, do this

I hope I helped! I wish you a merry christmas! :D
