How can you save your data for every server?

How can we save data just like coins datastore i tried as a test to once the part was touched it will change color to red and save it forever but it didn't work I'm just curious if we can make it happen with datastore and how?

I saw Alvin Blox's video to create it

Yes i edited it and put part and things that i should put there but it still didn't work. here is the script take a look :

local Part = game.Workspace.Part
local player = game.Players.LocalPlayer
local DataS = game:GetService("DataStoreService")
local GetPart = DataS:GetDataStore("GetPartStuff")

game.Players.PlayerAdded:Connect(function(player)
	Part.Touched:Connect(function(hit)
	if game.Players:GetPlayerFromCharacter(hit.Parent) then
		Part.Color = Color3.fromRGB(255,0,0)
		DataS:GetAsync(player.UserId)
	end
end)
end)

	game.Players.PlayerRemoving:Connect(function(player)
	GetPart:SetAsync(player.UserId,Part.Color == Color3.fromRGB(255,0,0))
	end)

You made the actual datastore but didn't use it right because you did DataS:GetAsync(). You were supposed to do GetPart:GetAsync()

To Fix it do this

game.Players.PlayerAdded:Connect(function(player) Part.Touched:Connect(function(hit) if game.Players:GetPlayerFromCharacter(hit.Parent) then Part.Color = Color3.fromRGB(255,0,0) GetPart:GetAsync(player.UserId) end end) end)

To get the data

You saved the data right though.
