Send a return string data from server to client

[Dzsozi (h03)]

Hello!

I would like to get the current account state variable on client side, so I can adjust my login interface based on that (if the player already has an account disable the register button, etc.).

My problem is I don't know how to do that, could somebody help me out? I need to call the function on client side, so I can't use element datas (as far as I know). Here's my server side script:

function getPlayerAccountState(playerSource)
	if (playerSource) then
		local accountState = "canCreate"
		local selectQuery = dbPoll(dbQuery(connection, "SELECT * FROM accounts"), -1)
		if (selectQuery) then
			for k, v in ipairs(selectQuery) do
				if (tostring(v["username"]):upper() == tostring(playerUsername):upper()) then
					accountState = "haveUsername"
					break
				end

				if not (getServerOwners(playerSerial)) then
					if (tostring(v["serial"]):upper() == tostring(playerSerial):upper()) then
						accountState = "haveAccount"
						break
					end		
				end
			end
		end
		
		return accountState
	end
end

Use triggerClientEvent in order to send the data you want to be sent to client side.

That doesn't really help me out.

An example of what I mean might help you out:

 

Server side:

function whateverEventYouAreUsing() -- The event that initializes login panel server side
  triggerClientEvent(source, "theClientSideEventThatInitializesLoginPanel", resourceRoot, getPlayerAccountState(source))
end

Client side:

function theClientSideEventThatInitializesLoginPanel(accountState)
  if (accountState == "haveAccount") then
	-- Do whatever you want when the player has an account
  else
	-- Do whatever you want when the player doesn't have an account
  end
end
addEvent("theClientSideEventThatInitializesLoginPanel", true)
addEventHandler("theClientSideEventThatInitializesLoginPanel", resourceRoot, theClientSideEventThatInitializesLoginPanel)

But on client side I need to use the function like on server side, so I need to call the function and then return the value given on server side, I want to use it inside a render function so like accountState = getPlayerAccountState(localPlayer), and then based on that I can disable or enable the register button, change it's color, add tooltip, whatever.

That'd be really inefficient calling this function over and over yet, that ain't possible I guess. A really efficient way that just come in my mind is that you initialize the account state when the player joins the server and store it in a global variable client side.

An example:

accountState = nil

function theClientSideEventThatInitializesLoginPanel(accState)
  accountState = accState
end
addEvent("theClientSideEventThatInitializesLoginPanel", true)
addEventHandler("theClientSideEventThatInitializesLoginPanel", resourceRoot, theClientSideEventThatInitializesLoginPanel)

function render() -- Your rendering function
  -- Here you can use the accountState variable however you like.
end

Got it working and now I understand how it works. Thank you!
