Getting Nil instead of Vector3

Help and Feedback Scripting Support

The script below is part of a multiscript system that generates an infinite number of ordered blocks (neighborhood blocks like a group of neighborhood homes). The specific script below is intended to save things about each home and load the home and all of it’s items with it. Each home is customizable by the player like in Bloxburg and therefore each object they place in/on their home will be saved with it’s position and orientation.

The problem is that whenever saving the location and orientation of each part it seems to always give nil. I’m not exactly sure if it’s just not saving the position and orientation or if it’s returning it in a different format.

I’ve rewritten the whole script a few times and this is the most optimized version I’ve written so far. I’ve add lots of prints around the script to help track how far along the path the system gets before something goes wrong.

Here is the script, it’s a module script in the server script service:

local HttpService = game:GetService("HttpService")
local Datastore = game:GetService("DataStoreService")
local homeData = Datastore:GetDataStore("homeData")
local playerData = Datastore:GetDataStore("playerData")

local HomeLoader = {}

function HomeLoader.SaveHome(block, owner, index, Home)
	print("Saving home "..block..":"..index.."...")
	local HomeData = { Owner = tonumber(owner), Objects = {} }
		
	for _, child in pairs(Home:GetChildren()) do
		table.insert(HomeData.Objects, {
			Name = child.Name,
			Position = child.Position,
			Orientation = child.Orientation
		})
	end

	homeData:SetAsync(block..":"..index, HttpService:JSONEncode(HomeData))
	print("Home "..block..":"..index.." saved!")
end

function LoadHome(block, i, player)
	print("Loading Home...")
	local _HomeData = homeData:GetAsync(block..":"..i)
	if _HomeData then
		local HomeData = HttpService:JSONDecode(_HomeData)
		local NewHome = game.ReplicatedStorage.Home:Clone()
		print("Home loaded!")
		NewHome.Name = tostring(block..":"..i)

		for _, Block in pairs(workspace.Blocks:GetChildren()) do
			if block == Block.Name then
				NewHome.Parent = Block.Homes
				NewHome:PivotTo(CFrame.new(Block.Road:WaitForChild(i).Position.X, 0, Block.Road:WaitForChild(i).Position.Z))
				break
			end
		end
		
		if HomeData.Objects then
			for _, value in pairs(HomeData.Objects) do
				print(value.Name)
				local object = game.ReplicatedStorage.Objects:FindFirstChild(value.Name):Clone()
				object.Parent = NewHome
				object.Name = value.Name
				object.Position = value.Position
				object.Orientation = value.Orientation
			end
		end

		for _, child in pairs(NewHome:GetChildren()) do
			child.Transparency = 1
			local info = TweenInfo.new(3, Enum.EasingStyle.Exponential)
			local goal = { Transparency = 0 }
			local Tween = game:GetService("TweenService"):Create(child, info, goal)
			Tween:Play()
		end

		-- Connect the ChildAdded event to save the home
		NewHome.ChildAdded:Connect(function(child)
			HomeLoader.SaveHome(block, player.UserId, i, NewHome)
		end)
		
		HomeLoader.SaveHome(block,player.UserId,i,NewHome)
	else
		local NewHome = game.ReplicatedStorage.DefaultHome:Clone()
		print("Home loaded!")
		NewHome.Name = tostring(block..":"..i)

		for _, Block in pairs(workspace.Blocks:GetChildren()) do
			if block == Block.Name then
				NewHome.Parent = Block.Homes
				NewHome:PivotTo(CFrame.new(Block.Road:WaitForChild(i).Position.X, 0, Block.Road:WaitForChild(i).Position.Z))
				break
			end
		end

		for _, child in pairs(NewHome:GetChildren()) do
			child.Transparency = 1
			local info = TweenInfo.new(3, Enum.EasingStyle.Exponential)
			local goal = { Transparency = 0 }
			local Tween = game:GetService("TweenService"):Create(child, info, goal)
			Tween:Play()
		end

		-- Connect the ChildAdded event to save the home
		NewHome.ChildAdded:Connect(function(child)
			HomeLoader.SaveHome(block, player.UserId, i, NewHome)
		end)

		HomeLoader.SaveHome(block,player.UserId,i,NewHome)
	end
end

function HomeLoader.LoadHomes(block)
	for i = 1, 4 do
		local _HomeData = homeData:GetAsync(block..":"..i)
		if _HomeData then
			print("Home found for "..block..":"..i.."!")
			local HomeData = HttpService:JSONDecode(_HomeData)
			LoadHome(block, i, HomeData.Owner)
		else
			print("No home found for "..block..":"..i.."!")
			local ProxPrompt = Instance.new("ProximityPrompt")

			for _, Block in pairs(workspace.Blocks:GetChildren()) do
				if block == Block.Name then
					ProxPrompt.Parent = Block.Road:FindFirstChild(i)
				end
			end

			ProxPrompt.Triggered:Connect(function(player)
				if player.leaderstats.Silver.Value >= 2000 and player.Homes.Value < 1 then
					player.leaderstats.Silver.Value -= 2000
					player.Homes.Value += 1
					
					ProxPrompt.Enabled = false
					LoadHome(block, i, player)
				end
			end)
		end
	end	
end

return HomeLoader

If you are trying to JSONEncode Vector3’s, you cant. You are going to have to save the individual components in an array.

Something like
{Position = {X, Y, Z}, Orientation = {X, Y, Z}}

Thank you SO MUCH! I literally cannot thank you enough. I didn’t think the problem was something as simple as that!

You can also use tostring(UserData) to convert pretty much anything (as far as I know of) to a serializable string, instead of putting them manually in a table. (UserData’s are basically roblox data types, like Vector3, CFrame, Color3, etc)
