How would I detect the amount of certain objects continuously?

Hi, my original script is a bit longer, but I’m trying to make a system where it counts the number of objects based on a name, i.e number of cheese and number of bacon.

However, there’s more than just those 2 objects and I can’t continuously make if then statements.
I’m also unable to make my script be able to detect if there is a loss of object too, so can you help me in this?

local FOLDER = workspace.Folder

local CHEESE = 0

for i,v in pairs(FOLDER:GetChildren()) do
	if v.Name == "Cheese" then
		
		
		CHEESE = CHEESE + 1
	end
end

print(CHEESE)

You could keep a dictionary that has a list of objects and a set value to them:

local FOLDER = workspace.Folder

local OBJECTS = {
     ['Cheese'] = 0
}

for i,v in ipairs(FOLDER:GetChildren()) do
	if OBJECTS[v.Name] then -- checks if the OBJECTS table has the object's name in it
		OBJECTS[v.Name] += 1 -- adds one
	end
end

print(OBJECT.Cheese)

For your script to detect an object’s removal, you can do something like this:

FOLDER.DescendantRemoving:Connect(function(desc)
   if OBJECTS[desc.Name] then
      OBJECTS[desc.Name] -= 1 -- removes 1
   end
end)

Here is my best shot at this:

-- Your folder
local FOLDER = workspace.Folder

-- Need this for storing our numbers
local foodDictionary = {
    ["CHEESE"] = 0,
    ["PIZZA"] = 0,
    ["ICECREAM"] = 0
}

for _, food in ipairs(FOLDER:GetChildren()) do
    -- Checking if our food is even valid
    if foodDictionary[food.Name] then
        foodDictionary[food.Name] += 1
    end
end

print(foodDictionary.CHEESE) -- Returns amount of cheese

Every time you want to add a new food, add it to the dictionary!
