How do I make map-based resource collection/inventory tracking?

Hey, there!

I am currently working on an open-world sandbox game, and the main feature I want in it is being able to destroy parts of the map for building materials (and yes, I want the materials to be stackable). There will then be an inventory you can access with "e" where you can select what materials you want to build with. Also, after a match is complete, I want the map to regenerate without having to rejoin another server. I know how to regenerate a map, but I don't know if the script I have will interfere.

model = game.Workspace.map
messageText = "Regenerating map..."

message = Instance.new("Message")
message.Text = messageText
backup = model:clone()

while true do
	wait(600) 

	message.Parent = game.Workspace
	model:remove()

	wait(4) 

	model = backup:clone()
	model.Parent = game.Workspace
	model:makeJoints()
	message.Parent = nil
end

Please let me know if my regen script will work and how to make a resource collector/inventory tracker.
