Get the return from server events in client side

[PutoBoina_JP]

Hello,

Whenever I try to return a value in a server event so I can access that value in the client script, it doesn’t work. It only returns false. Why? Am I doing something wrong?

Server script

RegisterNetEvent('GetPlayerIdentifier')
AddEventHandler('GetPlayerIdentifier', function()
    local _src = source
    local id = GetPlayerIdentifiers(_src)[3]
    print(id) -- this prints the correct id

    return id
end)

Client script

local playerId = TriggerServerEvent('GetPlayerIdentifier')
print(playerId)

In-game Output

Thanks for reading!

you cant return it like this maybe you try this:

client side:

local playerId = nil

RegisterNetEvent(‘PlayerIdentifier’)
AddEventHandler(‘PlayerIdentifier’, function(id)
playerId = id
print(playerId)
end)

serverside:

RegisterNetEvent(‘GetPlayerIdentifier’)
AddEventHandler(‘GetPlayerIdentifier’, function()
local _src = source
local id = GetPlayerIdentifiers(_src)[3]
print(id)

TriggerClientEvent('PlayerIdentifier', _src, id)

end)

Yup, that works! Thanks!

So, if the return is always false, that means I can’t use a return unless I want to close or break that event, right? Or is there an exception?

And one more question. Is there any way to do that without triggering a client event? I want to go directly to the main thread. Some kind of callback or something…

If every time I go to the server side I have to do as you have exemplified, my code will get 2 or 3 times bigger, which is not good in many ways!

I just had this conversation yesterday

[SOLVED] What is the best way to share information between client and server? [C# - Lua - JS]

Hi there, I’ve been trying to figure out the best way to exchange information between a client-side and a server-side resource. It often happens (at least in my case) that I need to request a server-side information from the client. However, I haven’t found an optimal way to do this. The only thing I could think of is triggering a server-side event from the client, and then triggering a client-side event from the server as a response. It would still be much better if there was a more efficient …

(He is doing it in C#, but I also posted Lua examples.
