How do i make the parts stop deleting if barricade1remove is not touched anymore?

local part = script.Parent
local cframe = part.CFrame

-- Keeps track of whether the player is currently touching the brick.
local touching = false


local function onTouched(hit)
    local character = hit.Parent

    if game.Players:GetPlayerFromCharacter(character) then
        touching = true -- A player started touching the brick.
    end
end

local function onTouchEnded(hit)
    local character = hit.Parent

    if game.Players:GetPlayerFromCharacter(character) then
        touching = false -- A player stopped touching the brick.
    end
end


part.Touched:connect(onTouched)
part.TouchEnded:connect(onTouchEnded)


local parts = {}

-- Every 0.1 second, check if the brick is touched.
while true do
    -- Execute code as long as the player is touching the brick
    -- and there are parts to delete.
    while touching and #parts > 0 do
        -- Remove the last part from the list then delete it.
        local partToDelete = table.remove(partToDelete)

        partToDelete:Destroy()
        -- Note how I use "Destroy()" instead of "Remove()". 
        -- This is because remove is a deprecated method. You shouldn't use it anymore.
        wait(0.01)
    end

    wait(0.1)
end
