How to save Build Mode

Help and Feedback Scripting Support
#1

Hey there, developers!

I want to know, how do you save Part’s names and their positions,

I have tried converting it to a string then converting it to a number, but that was unsuccessfull.

Here are my scripts:

Saver:

local ds = game:GetService("DataStoreService"):GetDataStore("Build")

game.Players.PlayerRemoving:Connect(function(player)
	for i,v in pairs(workspace.BlocksPlaced:GetChildren()) do
		if v.Name == "PlacedBlock" then
			local name = tostring(v:GetAttribute("Name"))
			
			local async = ds:GetAsync(player.UserId)
			
			local pos = tostring(v.Position)
			table.insert(async, {name, pos})
			
			ds:SetAsync(player.UserId, async)
			
		end
	end
end)

Loader:

local ds = game:GetService("DataStoreService"):GetDataStore("Build")

game.Players.PlayerAdded:Connect(function(player)
	local async = ds:GetAsync(player.UserId)
	if async then
		for i,v in pairs(async) do
			print(tonumber(async[v]))
			print(tonumber(async[v][1]))
			print(tonumber(async[v][2]))
			local blockFound = game.ServerStorage.Models:FindFirstChild(tonumber(async[v][1]))

			local clone = blockFound:Clone()

			clone.Position = Vector3.new(tonumber(async[v][2]))
		end
	end
end)

I am not good at Build Modes, so any help is appreciated.

(i am going offline so i won’t be able to respond but i can after school tomorrow!)

I’m not sure why you want to save the CFrame as a string. The name of the object should already be a string.

Here’s a way that works:

local CF = CFrame.new()
local data = {CF:GetComponents()}
--you can save it now
local savedCF = CFrame.new(unpack(data))

What does the CF do? I’ve never seen situations where i only used CFrame.new()

CFrame.new() just returns a CFrame where all the components are 0.

If you’re storing positional values in Datastore use position instead with a separate rotation value. Also, if you’re building game uses a grid you can just divide your position by your grid size and save that.

CF is just a variable. That code is just an example howing how I can get a CFrame (in this example, the variable CF), convert it into a table (which you can save), then convert it back into a CFrame (whenever you wanna load the data)

You will need to make your own CFrame using a table. For saving, use

local pos = {v.Position.X, v.Position.Y, v.Position.Z, v.Orientation.X, v.Orientation.Y, v.Orientation.Z}

No tostring()'s needed.

And for loading:

clone.CFrame = CFrame.new(async["Position"][1], async["Position"][2], async["Position"][3])*CFrame.fromEulerAnglesXYZ(math.rad(async["Position"][4]), math.rad(async["Position"][5]), math.rad(async["Position"][6]))

Let me know if that helps :slight_smile:

Unfortunately, i cannot test this now, but i might be able to tommorow since i have a bad migraine :slight_smile:

-- save data
local data = {cFrame:GetComponents()}
ds:SetAsync(key, data)

-- get data
local unpacked = unpack(ds:GetAsync(key) or {})
block.CFrame = CFrame.new(unpacked)

that’s not all the components of a CFrame, so that won’t work.

It works in my code, and he is doing something similar, so I see no reason why it shouldn’t work.

Hey friend, you might want to look into Instance DataStore!

I’ve just tried implementing that into my code, it seems to not work, here is the code:

my module (i made it so that when you place an object, it updates the datastore)

function module.place(block, mouse, player)
	if mouse then
		local clone = block:Clone()
		print(mouse.Name)

		if mouse:GetAttribute("PartAbove") == false then
			if mouse.Name == "PlacedBlock" then
				print'no'
				clone.Parent = workspace.BlocksPlaced
				local cha = clone.Size.Y
				print(cha)
				clone:SetAttribute("Creator", player.Name)
				clone.CFrame = mouse.CFrame +Vector3.new(0,cha,0)
				clone.Name = "PlacedBlock"
				
				mouse:SetAttribute("PartAbove", true)
				
				local name = tostring(clone:GetAttribute("Name"))
				
				local pos = {clone.Position.X, clone.Position.Y, clone.Position.Z, clone.Orientation.X, clone.Orientation.Y, clone.Orientation.Z, clone:GetAttribute("Name")}
				
				local info = ds:GetAsync(player.UserId)
				
				if info then
					table.insert(info, pos)
				else
					local i = {pos}
					
					
				end
				wait()
				ds:SetAsync(player.UserId, info)
				print'done'
			else
				clone.Parent = workspace.BlocksPlaced
				local cha = clone.Size.Y/2
				print(cha)
				clone:SetAttribute("Creator", player.Name)
				clone.CFrame = mouse.CFrame +Vector3.new(0,cha,0)
				clone.Name = "PlacedBlock"
				
				local name = tostring(clone:GetAttribute("Name"))

				local pos = {clone.Position.X, clone.Position.Y, clone.Position.Z, clone.Orientation.X, clone.Orientation.Y, clone.Orientation.Z, clone:GetAttribute("Name")}

				local info = ds:GetAsync(player.UserId)

				if info then
					table.insert(info, pos)
				else
					local i = {pos}


				end
				wait()
				ds:SetAsync(player.UserId, info)
			end
		end


	end


end

script: (loader)

local ds = game:GetService("DataStoreService"):GetDataStore("Build")

game.Players.PlayerAdded:Connect(function(player)
	local async = ds:GetAsync(player.UserId)
	if async then
		for i,v in pairs(async) do
			local blockFound = game.ServerStorage.Models:FindFirstChild(tostring(async[v][1]))

			local clone = blockFound:Clone()

			clone.CFrame = CFrame.new(async["Position"][1], async["Position"][2], async["Position"][3])*CFrame.fromEulerAnglesXYZ(math.rad(async["Position"][4]), math.rad(async["Position"][5]), math.rad(async["Position"][6]))
			clone.Name = "PlacedBlock"
			clone.Parent = workspace.BlocksPlaced
			clone:SetAttribute("Name", async["Name"][7])
		end
	end
end)

There is an error here:

local blockFound = game.ServerStorage.Models:FindFirstChild(tostring(async[v][1]))

the error is

  ServerScriptService.Loader:7: attempt to index nil with number
