how do i limit how many parts can my script spawn at once?

hi hello im dumb and i cannot script so i'm asking you people that are way better at this than me for some tiny bit of help, i want to make my game not lag by limiting how many parts the player can spawn at once. i have no clue what i'm doing

local part = script.Parent
local brick = Instance.new("Part", workspace)
local parts = 0

while parts < 30 do

part.ClickDetector.MouseClick:connect(function(player)
	parts.Value = parts.Value + 1
	brick.Position = game.Workspace.jeff.Position
	brick.Material = Enum.Material.Brick
	brick.BrickColor = BrickColor.Random()
	brick.Transparency = 0
	brick.Size = Vector3.new(2, 2, 2)
	part.BrickColor = BrickColor.new("Really red")  -- this changes the color of the button that player presses to make the bricks
	wait(0.1)
	part.BrickColor = BrickColor.new("Lime green")
	wait(0.1)
	wait(30)  -- waits a certain amount of time and then destroys the bricks for example if theres too many at once
	brick:Destroy()
	end)
end

any help would be gladly appreciated i'm losing my mind over this it's probably just a quick easy thing but i'm too incompetent for scripting ok byebye!!

Try this

local part = script.Parent.Parent
local brick = Instance.new("Part", workspace)
local parts = 0


	part.ClickDetector.MouseClick:connect(function()
		parts = parts + 1
		if parts <= 30 then
			brick.Position = game.Workspace.jeff.Position
			brick.Material = Enum.Material.Brick
			brick.BrickColor = BrickColor.Random()
			brick.Transparency = 0
			brick.Size = Vector3.new(2, 2, 2)
			part.BrickColor = BrickColor.new("Really red")
			wait(0.1)
			part.BrickColor = BrickColor.new("Lime green")
		wait(0.1)
		
		while true do
			wait(1)
			if parts >= 30 then
				brick:Destroy()
			end
		end
	end
end)

while parts < 30 do

This line of code only serves to endlessly reconnect the event, which is a bad thing to do.

Instead you could just use the event, but add an if statement inside of the event.

local part = script.Parent
local brick = Instance.new("Part", workspace)
local parts = 0


part.ClickDetector.MouseClick:connect(function(player)
    if parts > 30 then return end
    parts = parts + 1
    brick.Position = game.Workspace.jeff.Position
    brick.Material = Enum.Material.Brick
    brick.BrickColor = BrickColor.Random()
    brick.Transparency = 0
    brick.Size = Vector3.new(2, 2, 2)
    part.BrickColor = BrickColor.new("Really red")  -- this changes the color of the button that player presses to make the bricks
    wait(0.1)
    part.BrickColor = BrickColor.new("Lime green")
    wait(0.1)
    wait(30)  -- waits a certain amount of time and then destroys the bricks for example if theres too many at once
    brick:Destroy()
    parts = parts - 1
end)

You have a couple of other problems, like you need to decrease the number of parts (so I added that in my example) and you also forgot that for variables like parts, you don't need .Value

Good luck, Vathriel
