Some helpful information on datastores?

Im working on datastores for the first time but I have some unanswered questions.

here is my datastore script:

local plr = game.Players:FindFirstChild(script.Parent.Name)
if not plr then
	repeat wait() until plr
end
local datastore = game:GetService("DataStoreService")
	local mydata = datastore:GetDataStore("mydata")
local value = script.Parent.Gems
value.Changed:Connect(function()
	
	local success, fail = pcall(function()
		mydata:SetAsync(plr.UserId.."Gems",value.Value)
	end)
	if success then
		print("data saved")
	else
		print("an error has occured while saving")
		warn(fail)
	end
end)

game.Players.PlayerAdded:Connect(function(player)
	
	local data
	local success, fail = pcall(function()
		data = mydata:GetAsync(player.UserId.."Gems")
	end)
	if success then
		value.Value = data
	else
		print("data load failed")
		warn(fail)
	end
	
end)

the script starts in the character but then relocates to serverscriptservice. I put it there so data can be safe. but I ran into a problem, I need a client side gui to read off of the value “Gem(s)”
but because its in serverscriptservice the client cant see it. if I put it in a place like the workspace its vulnerable to attackers.

also, the script has not been tested yet so if there are any errors please let me know.

So this is an opportunity to start understanding the server/client model.

Even though you have this server script inside the character, the player(client) cannot access the data because the code is being executed on the server. So obviously you need a way for players/server to communicate and the answer to that is RemoteEvents/RemoteFunctions.

In your case you’d want something along the lines of

  1. Player joins game and server loads data
  2. Player local scripts execute and request data from server using remote function
  3. Server retrieves data and returns data to client
  4. Client displays data in some graphical format.

Edit: This is just a quick short version to give you some ideas to research on your own, there are tons of tutorials on the forums that do a much better job explaining than I ever could.

so I got it working with one remote function in replicatedstorage,but all clients will be requesting from that remote function every 0.5 seconds. will this overload the remote function or can it handle many requests at the same time?

That’s not a very good way of requesting data.

In my opinion, the best way to handle a player seeing his data is to place the values somewhere in ReplicatedStorage so you can see the data without having to use RemoteFunctions.

The only thing wrong with this model, though, is that exploiters can see other players’ data. If that’s something you’re fine with, go ahead and put it in ReplicatedStorage.

no, as I stated before data is going to be inside serverscriptservice in the case of attackers.

What kind of attackers?

If you don’t want other players to see everyone’s data, I’d understand, but you should know that even if they can see the data, they can’t change it at all. The “changes” they make are only client sided for the exploiter, and for everyone else the data remains the same.

It doesn’t seem like you completely understand what attackers can do, so here’s a helpful article on how the Roblox Client-Server Model works. Client-Server Runtime | Documentation - Roblox Creator Hub

Many games run 100+ remote event/function calls a second. But in this case that is extremely wasteful. A better way would be to have the server fire a remote event only when there is a change in your data set.

acually I made a post about attackers and got some really good information. so I know what attackers are capable of. heres the post
