Calling table from export

[VenomOG]

Hello so heres the codes
SERVER
 

local TitlesTable = {
	
}

function getTitlesTable()
	return TitlesTable
end

CLIENT THAT IS CALLING EXPORT
 

for i, k in ipairs(exports.HIDDEN:getTitlesTable()) do 
			dxDrawRelativeRectangle(598, 219+i*30, 296, 30, isMouseInPosition((598/resolutionX )*sWidth,((219+i*30)/resolutionY )*sHeight, (219/resolutionX )*sWidth, (32/resolutionY )*sHeight) and tocolor(255, 255, 255, 158) or tocolor(0, 0, 0, 158))
			dxDrawRelativeText(k[1], 701, 200+i*30, 785+40, 239+(i+1)*30, tocolor(255, 255, 255, 255), 0.40, dxfont5_bebas_font, "left", "center")
			
		
        end

META
 

<meta>
   <info author="Hidden" name="Titles" type="script" version="1.1.0" description="Hidden Titles" />

    <script src="client.Lua" type="client"/>
    <script src="server.Lua" type="server"/>
    <file src="fonts/font.ttf"/>
	<export function="createTitle" type="server" />
<export function="equipCT" type="client" />
<export function="getTitlesTable" type="server" />

</meta>

So it gives me an error

failed to call 'HIDDEN:getTitlesTable' [string "?"]

Any suggestions?

first of all make sure getTitlesTable() is a client side function because you exported it as "server" side in meta.xml file..

server side functions unusable for client side

after that make sure you have started HIDDEN resource..

if that didn't help you , delete this from loop :

exports.HIDDEN:getTitlesTable()

and add this :

exports['HIDDEN']:getTitlesTable()

sometimes first way not works..

You should make use of events, because you are unable to define the export for client-side when your function is being defined on server-side. If you want to stick with functions just create a function on client-side to retrieve the table from the server and then return the value.

Um example please.

Serverside is running on the server.
Application (in case of a local server): Program Files (x86)\MTA San Andreas 1.5\server

 

Clientside is running on clients/players.
Application: Program Files (x86)\MTA San Andreas 1.5\Multi Theft Auto.exe

Those are two very different applications. And between those two applications there is something called ping, = connection delay. Even a local server has a little bit of ping, even though it is displayed as 0.

 

Your code does not wait for ping, it just runs until it finished all the instructions you gave it.

If you want to let those two sides communicate with each other you need to use triggerEvent. See examples on these pages:

From clientside to serverside: (examples included)

Enchantment

You can also use an enchantment, which I created for people that have trouble with communication between serverside and clientside.

Installation

 

Clientside

addEventHandler("onClientResourceStart", resourceRoot, 
function () 
	callServer(
		"getTitlesTable", 
		function (TitlesTable_) -- < This is the callback function
			TitlesTable = TitlesTable_
		end
	)
end)

 

Clientside

if TitlesTable then
	for i, k in ipairs(TitlesTable) do 
		dxDrawRelativeRectangle(598, 219+i*30, 296, 30, isMouseInPosition((598/resolutionX )*sWidth,((219+i*30)/resolutionY )*sHeight, (219/resolutionX )*sWidth, (32/resolutionY )*sHeight) and tocolor(255, 255, 255, 158) or tocolor(0, 0, 0, 158))
		dxDrawRelativeText(k[1], 701, 200+i*30, 785+40, 239+(i+1)*30, tocolor(255, 255, 255, 255), 0.40, dxfont5_bebas_font, "left", "center")
	end
end

 

Serverside

- no changes -

create a client side variable in AKA UCP script and get the table using triggerServerEvent then receive the table using triggerClientEvent then make the variable you've created equals received table 

-- client
local variable;

triggerServerEvent("onPlayerCallTable",localPlayer);


addEvent("onClientReceivedTable",true);
addEventHandler("onClientReceivedTable",root,
  	function(TitlesTable)
    	variable = TitlesTable;
    end
)


function getTable()
  	return variable;
end


-- server

TitlesTable = {};

function getTitlesTable()
  	return TitlesTable
end

addEvent("onPlayerCallTable",true)
addEventHandler("onPlayerCallTable",root,
  	function()
    	triggerClientEvent(source,"onClientReceivedTable",source,getTitlesTable());
    end
)
