returning a value (from an event) returns nil?

Asked 2,302 views1 answers

hi all, so my game is filtering enabled and i've come across a problem trying to 'read' stats (which are an assortment of stringvalues, intvalues, etc.) in serverstorage under a folder with the players name. in the localscript (player's gui), the line is this:

local maxStam = repStorage.Calls.ReadStat:FireServer("maxStamina")

in the server script (serverscriptservice) which connects to the event, the function looks like this:

game:GetService("ReplicatedStorage").Calls.ReadStat.OnServerEvent:Connect(function(player, stat)
	return game.ServerStorage[player.Name]:findFirstChild(stat).Value
end)

this returns a nil value and it can't be modified in any way (as it is a nil)

any help will be appreciated!

A remote event does not return a value to the client like a remote function.

To resolve this you can either, send the data back with FireClient inside the function or use a remote function which allows you to return a value to the client.

Using a remote event example:-

-- server script
local servStorage = game:GetService('ServerStorage')
local rmtEvent = game:GetService('ReplicatedStorage').Calls.ReadStat

rmtEvent.OnServerEvent:Connect(function(player, stat)
	rmtEvent:FireClient(player, stat, servStorage[player.Name]:FindFirstChild(stat).Value
end)

-- local script

-- we need to wait until the client has the remote event
local rmtEvent = game:GetService('ReplicatedStorage'):WaitForChild('Calls'):WaitForChild('ReadStat')

rmtEvent.OnClientEvent:Connect(function(stat, value)
	print(stat, value)
end)

rmtEvent:FireServer("maxStamina")

Using a remote function example:-

-- server script
local servStorage = game:GetService('ServerStorage')

function [path to remtoe function].OnServerInvoke(plr, stat)
	return servStorage[player.Name]:FindFirstChild(stat).Value
end

-- local script
local rmtFucntion = [path to remote function]

print(rmtFucntion:InvokeServer('maxStamina')) -- prints max stamina

I hope this helps.
