Repeating something until a number is reached

Help and Feedback Scripting Support

I have a spawner that creates a part instance and puts it into a folder.
How would I make it so that the spawner keeps spawning a part every 2 seconds until there is 100 parts?

How would I make the script also count the parts in the folder so that if any parts are destroyed, it would start creating parts again until the 100 part limit is hit?

I have tried using the repeat until loops and while loops, but seem to get lots of errors, and cannot figure out the best way to do this without using things like while true do loops etc.

I was thinking of a for loop:

local PartAmount = #PartFolder:GetChildren()
for i = 1, 100 - PartAmount do
 task.wait(2)
— ceate instance here
end

that works great at first when the server starts, but how would I go about making it so that if the part count changes, it creates parts again until reaching 100?

I assume something like this:

local PartFolder = Instance.new("Folder")
PartFolder.Name = "PartFolder"
PartFolder.Parent = game.Workspace
	
while task.wait(2) do
	for i = 1, 100 - #PartFolder:GetChildren() do
		if i ~= 100 then
			--create instance here
            local part = instance.new("Part")
            part.Parent = partFolder
		end
	end
end

I changed the code a little bit. Correct me if I am wrong.

We can make a while loop, and check every 2 seconds, like you asked, if there are a 100 parts, if not, then create a new one.

Script (sorry made this on mobile):

while true do
local PartAmount = #PartFolder:GetChildren()
if PartAmount < 100 then
--create instance here
end
task.wait(2)
end

local partFolder = instance.new("Folder")
partFolder.Name = "PartFolder"
partFolder.Parent = game.workspace

local function check() 
  parts = game.workspace:getChildren()
  

  for i = 1,100 do

    if #parts >= 100 then
       continue
    else
      local part = instance.new("Part")
      part.Parent = partFolder
    end

  end
end

while true do
  wait(1)
  check()
end

local folder=workspace:WaitForChild("insertfoldername")
local part=folder:WaitForChild("insertpartname")

task.spawn(function()
	while true do
		task.wait(2)
		local partClone=part:Clone()
		partClone.Parent=folder
		if #folder:GetChildren()>=100 then
			--put code here
           break
		end
	end
end)

While these solutions could work, using a loop to check when a child is gone is not optimal.
Try using signals where possible to minimize how much the code runs.

local spawning = false
local queue = false
local function spawnParts()
  if spawning then 
    queued = true
    return
  end
  spawning = true
  
  local children = partsParent:GetChildren()
  local targetCount = 100
  for i = 1, targetCount - #children do
    -- spawn things
    task.wait(2)
  end
  
  spawning = false
  if queued then
    queued = false
    spawnParts()
  end
end

partsParent.ChildRemoved:Connect(spawnParts)
spawnParts()
