Need help with position saving datastore

You can write your topic however you want, but you need to answer these questions:
Hi everyone! I’m new to datastores, but I want to start learning them. I’m making a datastore that saves a player’s position from the HumanoidRootPart whenever they leave the game.

The datastore doesn’t save and casts the error “Unable to cast value to Object”.

local DataStoreService = game:GetService("DataStoreService")

local DataStore = DataStoreService:GetDataStore("PositionDataStore")


game.Players.PlayerAdded:Connect(function(player)
	player.CharacterRemoving:Connect(function(character)
		local success, errormessage = pcall(function()
			DataStore:SetAsync(player.UserId,player.Character.HumanoidRootPart.Position.X,player.Character.HumanoidRootPart.Position.Y,player.Character.HumanoidRootPart.Position.Z)
		end)

		if success then
			print("success")	
		else
			print("fail")
			warn(errormessage)
		end
	end)
end)

Doesn’t work either because of Vector3 stuff. Tried it already. Thanks for the suggestion though!

Hey there,

Saving positions in DataStores isn’t something you can do. Instead, you can save a dictionary with the with the x, y, and z coordinates of that position, and when the player joins again, use that dictionary to construct a vector3.

local rootPosition = humanoidRootPart.Position
local positionTable = {
    x = rootPosition.X, 
    y = rootPosition.Y, 
    z = rootPosition.Z
}
DataStore:SetAsync(player.UserId, positionTable)

Then when you receive the data, you can construct a position by doing this

local positionTable = DataStore:GetAsync(player.UserId)
local position = Vector3.new(positionTable.x, positionTable.y, positionTable.z)

Hope this helps :slight_smile: Lemme know if you have any more questions

You passed on a parameter called characterin the CharacterAdded event. You can use that in the SetAsync() part. Or, you can save the HumanoidRootParts cframe instead of it’s position.
