Problem with GUI.

[Bumbis]

Hi everyone! I have stupid problem with GUI. It doesnt show nothing, just black screen when i connect. But it needs to be appeared. I have a mysql server and i connect it, its all ok with connection, but i think that the problem is in my client side script. Please look at my Server-side and Client-side scripts, i will appreciate that.

Server-side:

function connectMysql() 
    handler = mysql_connect("localhost", "root", "", "phptest") -- Establish the connection 
    if ( not handler ) then -- The connection failed 
      outputDebugString("Unable to connect to the MySQL server. Server is shutting down.") 
      stopAllResources() 
    else 
        outputDebugString("MYSQL loaded successfuly") 
    end 
end 
addEventHandler("onResourceStart",getRootElement(),connectMysql) 
  
function stopAllResources() 
    -- we store a table of resources 
    local allResources = getResources() 
    -- for each one of them, 
    for i, resource in ipairs(allResources) do 
        -- if it's running, and it is not the current resource 
        if ( getResourceState(resource) == "running" ) then 
            -- then stop it 
            stopResource(resource) 
        end 
    end 
end 
  
function joinHandler(player) 
    local x = 1959.55 
    local y = -1714.46 
    local z = 10 
    fadeCamera(source, true) 
    setCameraTarget(source,source) 
    outputChatBox("Hey,"..getPlayerName(source).."!", source) 
end 
  
function Showname(playerSource) 
    outputChatBox("Tavs vards ir - "..getPlayerName(playerSource)..".",playerSource) 
end 
addCommandHandler("name",Showname) 
  
  
function Showhelp(playerSource) 
    outputChatBox("#FAD904|-------| Kommandas |-------|",playerSource,0,0,0,true) 
    outputChatBox(" /help /name /veh",playerSource) 
    outputChatBox("#FAD904|---------------------------|",playerSource,0,0,0,true) 
end 
addCommandHandler("help",Showhelp) 
  
function vehicle(playerSource,commandName,vehid) 
    local x,y,z = getElementPosition(playerSource) 
    createVehicle(tonumber(vehid),x+1,y,z+0.2) 
end 
addCommandHandler("veh",vehicle) 
  
  
local chatRadius = 20  
function sendMessageToNearbyPlayers( message, messageType ) 
    if messageType == 0 then 
        local posX, posY, posZ = getElementPosition( source ) 
  
        local chatSphere = createColSphere( posX, posY, posZ, chatRadius ) 
        local nearbyPlayers = getElementsWithinColShape( chatSphere, "player" ) 
        destroyElement( chatSphere ) 
  
        for index, nearbyPlayer in ipairs( nearbyPlayers ) do 
            outputChatBox( getPlayerName(source).." saka#FFFFFF: "..message, nearbyPlayer,180,180,180,true ) 
        end 
    end 
end 
addEventHandler( "onPlayerChat", getRootElement(), sendMessageToNearbyPlayers ) 
  
function blockChatMessage() 
    cancelEvent() 
end 
addEventHandler( "onPlayerChat", getRootElement(), blockChatMessage ) 
  
function Mecmd( message, messageType ) 
    if messageType == 0 then 
        local posX, posY, posZ = getElementPosition( source ) 
  
        local chatSphere = createColSphere( posX, posY, posZ, chatRadius ) 
        local nearbyPlayers = getElementsWithinColShape( chatSphere, "player" ) 
        destroyElement( chatSphere ) 
  
        for index, nearbyPlayer in ipairs( nearbyPlayers ) do 
            outputChatBox(getPlayerName(source).." saka#FFFFFF: "..message, nearbyPlayer,180,180,180,true ) 
        end 
    end 
end 
  
function checkPlayers() 
    if(handler) then 
        local q = mysql_query(handler,"SELECT * FROM mta_users WHERE Name='"..getPlayerName(source).."'") 
        if(mysql_num_rows(q) == 1) then 
            showCursor(source,true) 
            triggerClientEvent(getRootElement(),"CreateLoginWindow",getRootElement()) 
            triggerClientEvent(getRootElement(),"ShowLogin",getRootElement()) 
            mysql_free_result(q) 
        else if(mysql_num_rows(q)==0) then 
            showCursor(source,true) 
            triggerClientEvent(getRootElement(),"CreateRegisterWindow",getRootElement()) 
            mysql_free_result(q) 
            triggerClientEvent(getRootElement(),"ShowRegister",getRootElement()) 
        end 
    end 
end 
end

1. using so many events is a bit redundant (1 event to create and hide, next event to show?).

just create and hide windows on resource start, or use the same 1 event to create and show.

2. you're triggering client event for all players, not the one that needs it. use:

triggerClientEvent(source,"ShowLogin",getRootElement()) 

3. use "/debugscript 3" in game to see client-side script errors.

ACL: Access denied for debugscript 3. What's the problem with that?

[Zango]

You need to be admin on your server

https://wiki.multitheftauto.com/wiki/Admin

[Jack_Miller]

To do List:

-start your server

- type /register NAME PASSWORD eg: /register jack_miller lolapassword -- or register in console without the /

- shut down your server

- go in: MTA\server\mods\deathmatch

- open acl.xml

- find the admin category

- add under:

- (just the same just with your (registred) name)

- start your server

- /login NAME PASSWORD

- /debugscript 3

- be happy
