How would I check when an array gets a value then wait and remove it?
Hey guys,
I have a table in my script where it's a cooldown where every userId is placed in it. I want to detect when a value is added to it then wait a certain amount and then remove the user.
I know how to achieve that but my issue here is I only get to wait for the first value in the table.
Here is my attempted code.
local CooldownList = {}
--I insert values in the table elsewhere
coroutine.wrap(function()
print("Running coroutine")
while true do
wait()
if #CooldownList >= 1 then
coroutine.wrap(function()
repeat
print("Waiting and trying to remove user from array")
wait(45)
table.remove(CooldownList, 1)
print("Successfully removed user from array")
until #CooldownList < 1
end)()
end
end
end)()
Tbh, I just went with coroutines because I thought that was best.
Have a great day everybody ;)

I think I understand what you're trying to do, but I think polling (using a coroutine enclosed in a while loop that constantly runs) is the wrong answer. Plus, you've got a coroutine inside of a coroutine; that can get messy!
You can either use metatables or a function-based approach, but the former is generally over-engineering. Opting for the latter choice, here's what I would do:
local userIds = {}
local function addUserId(id)
table.insert(userIds, id) -- insert the id into the table
print("Added", id, "to userIds.")
delay(45, function() -- operate on a separate thread so this function does not yield any code it's used in
local index = table.find(userIds, id) -- locate where our userId async is via table.find's return argument
if index then -- ensure the index is legitimate
table.remove(userIds, index) -- remove the userId from the index
print("Removed", id, "from userIds index", index)
end
end)
end
You can use this example code to test it:
for i = 1, 5 do
addUserId(Random.new():NextInteger(100000, 1000000))
end
I would stress you remove the prints after you can ensure it's working properly. Hope this helps out, and please mark this as a solution if it does!!! Happy scripting.
