How to execute a part of code once in while loops?
Hi. I have a code and it has a while loop in it. I want code to do something in while loop only once. Here is an example;
while true do
doOnceThing
print('Script started.')
end
--Some other code
end
How can i do it?
EDIT: I know I can put print() outside loop but it's just an example I can't do it on my own code.

This can be solved with an if statement that is only true if the condition is met. Here is an example
local doOnceThing = 1
while true do
if doOnceThing == 1 then
--insert your code here
doOnceThing = doOnceThing + 1 --this will make it never run again
end
--Some other code
end
This is a bit crude since it will constantly check if doOnceThing is equal to 1, but it will solve your current problem.

If you mean to say, how do you know it's working for debuggin purposes; then add a print inside the if statement. If you mean to reference that doOnceThing has run, then compare it to the value of 2 since it added 1 to it. SteelMettle1 394 — 6y

fyi the local variable is read as nil in the loop DeceptiveCaster 3761 — 6y

thanks, I fixed the then. and I tabbed the local doOnceThing to show that it is within the same scope as the while loop SteelMettle1 394 — 6y

You can just do that thing before the while loop, like so:
print('Script started.')
while true do
-- Some other code
end
But if you specifically want the thing to be done in the while loop you can simply add a boolean to the code and then make something like this:
local didOnceThing = false
while true do
if didOnceThing == false then
print('Script started.')
didOnceThing = true
end
-- Some other code
end
Though it's better to use the first way.
