Hi! I am wondering how I can return a value from a remote event, like after firing it get the returned value. Say I want to transfer data from client to the server I fire a remote event from the server and I want to get data back from the client, how would I do that? Thank you - BMWLux :smiley:

You can’t, which is why RemoteFunctions exist.

Problem with retrieving value by remote event

So, these can work from the server to the client. Like I can fire it from the server and get back data from client?

Here’s an example:

-- server

local RS = game:GetService("ReplicatedStorage")

local event = RS.Events.RemoteFunction

event.OnServerInvoke = function(player: Player)
	-- do stuff here
	
	return "hi there"
end

-- local

local RS = game:GetService("ReplicatedStorage")

local event = RS.Events.RemoteFunction

warn(event:InvokeServer()) -- this prints out 'hi there'

Do note that InvokeServer() yields (pauses the script and waits for something to be returned).

local RS = game:GetService("ReplicatedStorage")

local event = RS.GiveBackSoundLoudness

event.OnClientInvoke = function(player: Player, sound)
	return sound.PlaybackLoudness
end

So can I put a sound paramenter if i invoke the client and put in the player param and the sound

Like how can I run a second parameter through it?

function(player: Player, sound, yourParameter ) just use a comma and add another value

local PBL = game.ReplicatedStorage.GiveBackSoundLoudness:InvokeClient(game.Players:GetChildren()[math.random(1, #game.Players:GetChildren())], ch)

Ok this is my fire script.


local RS = game:GetService("ReplicatedStorage")

local event = RS.GiveBackSoundLoudness

event.OnClientInvoke = function(Player: player, sound, thing)
	print(thing)
	print(sound)
	return sound.PlaybackLoudness
end

This is my return script. Any ideas why its printing nil?

Try printing out ‘ch’, check if it’s nil.

If it isn’t, try printing out all variables inside ‘OnClientInvoke’ (e.g. player, sound, thing).

#14

I have, ch isn’t nil. Any all of them print nil

Could you tell me what ‘ch’ is?

My exact script:

local OriginalSize = script.Parent.Handle.Mesh.Scale
local ts = game:GetService("TweenService")
print("PLAYING");
script.Parent.Handle.ChildAdded:Connect(function(ch)
	if ch:IsA("Sound") then
		ch.Changed:Connect(function()
			print("Changed");
			print(ch.Name)
			local PBL = game.ReplicatedStorage.GiveBackSoundLoudness:InvokeClient(game.Players:GetChildren()[math.random(1, #game.Players:GetChildren())], ch)
			print(PBL)
			local Multiplier = PBL + 0.4
			print(ch.PlaybackLoudness)
			print(Multiplier)
			local Tween = ts:Create(script.Parent.Handle.Mesh, TweenInfo.new(0.05), {Scale = Vector3.new(OriginalSize.X * Multiplier, OriginalSize.Y * Multiplier, OriginalSize.Z * Multiplier)})
			Tween:Play()
			wait(0.05)
		end)
		script.Parent.Handle.Mesh.Scale = OriginalSize
	end
end)

It also prints fine. Prints the exact name

Maybe try sending in ‘ch.Name’ and find the exact sound in the client itself?

Alright I guess I’ll try that. Maybe I go into sound service and scroll through a possible sounds and find it.
