Adding boundingbox support to my room loading system

Help and Feedback Scripting Support

(by bounding box, i mean a room will not load if its bounding box (or bounding boxes in theoretical reality), so that rooms that turn 90 degrees without going upwards won’t intersect a previous room, also i just have a really tall and thin room with a ladder in case all rooms fail to load somehow)
currently room loading is this

function module:loadnextroom()
	local needed:Model
	for _, v in spawnedrooms:GetChildren() do
		if v:HasTag("MostRecentlySpawned") then
			needed = v
		end
	end
	needed:RemoveTag("MostRecentlySpawned")
	needed.Door:Destroy()
	local room:Model = rooms[daft:randrand(1, #rooms, true)]:Clone()
	room:AddTag("MostRecentlySpawned")
	room:PivotTo(needed:FindFirstChild("Exit", true).CFrame)
	room.Door.lock.Lock.Touched:Connect(function(otherPart: BasePart) 
		module:attemptunlock(otherPart, room.Door.lock.Lock)	
	end)
	room.Parent = spawnedrooms
	NewRoom:FireAllClients(room)
	LoadedRoom:Fire(room)
end

and as described in ()s, i want rooms that turn without going upwards, bounding boxes is a possible solution but

  1. possible for no rooms to load (maybe…?)
  2. how the hell
