Packet | (De)Serialize folder instances

Help and Feedback Scripting Support
#1

Hi, I’m trying to get the folders, but something doesn’t work. I tried to serialize and deserialize them, but it didn’t work.

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Packet = require(ReplicatedStorage.Libs.Packet)

event = Packet("event"):Response({
    Folder1 = Packet.Instance,
    Folder2 = Packet.Instance,
    Folder3 = Packet.Instance
})

-- Client side

local folders = event:Fire()
-- Deserialize fire

local folders = event:Deserialize(event:Fire())

-- Server side

local folders = {
    Folder1 = Instance.new("Folder"),
    Folder2 = Instance.new("Folder"),
    Folder3 = Instance.new("Folder")
}

event.OnServerInvoke = function()
    return folders
end

-- Serialize invoke

event.OnServerInvoke = function()
    return event:Serialize(folders)
end

Hi there.

As far as I know everything automatically gets serialized and deserialized with Packet.
So all you have to do is remove the :Serialize() and :Deserialize() and it should work.

Also it’s best you just stay in the official Packet topic instead of redirecting to a new topic.

I tried not using serialize and deserialize and nothing works.

Here you are sending self.titlesUi, which is nil.
I believe you want to send self.uiTitles.

I hate lua language because it is not strict

#7

But in this piece of code self.titlesUi is empty

function PlayerTitleGuiHandler:RequestTitlesUi()
    self.titlesUi = self.titleEvents.requestGetTitlesUi:Fire()
end
#8

Yea but you set it to be what is on the server, so it works.

#9

I send a request from the client to get a list of titles, the server returns the list, but the client does not receive anything

#10

Have you tried printing self.uiTitles on both the client and server? On the server print before returning, and on the client print after receiving and setting it.

#11

Yes, I tried, the server says the full list is normal. It looks like this

["Developer"] = Developer,
["Meow"] = Meow,
["OG_Human"] = OG_Human,
["Sponsor"] = Sponsor,
["Survivor"] = Survivor,
["Tester"] = Tester

On the client {}

This is how the event is created

local TitleDataTemplate = {
  Survivor = Packet.Instance,
  OG_Human = Packet.Instance,
  Sponsor = Packet.Instance,
  Meow = Packet.Instance,
  Tester = Packet.Instance,
  Developer = Packet.Instance
}

TitleEvents.requestGetTitlesUi = Packet("RequestGetTitlesUi"):Response(TitleDataTemplate)
#12

The list of these titles is on ServerStorage. Maybe they should be in ReplicatedStorage?

#13

Yes, the problem was in ServerStorage

Solution is: Move your instances or someting else to ReplicatedStorage
