Understanding Remote Functions

Help and Feedback Scripting Support
#1

Basically I’m trying to make a remote function that invokes the clients mouse position and sends it to the a remote event to fire off a projectile. Honestly remote functions just continue to confuse me and I have no idea how to do this. sos

You can learn more about RemoteFunction instances here:

Can you provide the code you have thus far?

You don’t really want to invoke the client with remote functions, it’s usually better to use remote events.

– LOCAL SCRIPT –

local replStorage = game:GetService("ReplicatedStorage")
local clickEvent = replStorage:WaitForChild("ClickEvent")
local UIS = game:GetService("UserInputService")

UIS.InputBegan:Connect(function(input, processed)
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
		local clickPos = input.Position
		clickEvent:FireServer(clickPos)
	end
end)

– SERVER SCRIPT –

local replStorage = game:GetService("ReplicatedStorage")
local clickEvent = replStorage:WaitForChild("ClickEvent")

clickEvent.OnServerEvent:Connect(function(player, clickPos)
	--projectile code
end)

Current organisation in the explorer window. This solution makes use of a RemoteEvent.

RemoteFunctions are basically RemoteEvents, but you can return something. For example.

In a LocalScript:

local String = RemoteFunction:InvokeServer()
print(String)

In a ServerScript:

RemoteFunction.OnServerInvoke = function()
   return "Whats up?"
end

And the output would be:

Whats up?

This can be good for Code systems, or even the character shop inside of Bloxy Kart. Hope this helps!
