[Solved] Some issues on login GUI.

[Corsaro Quad]

Hi. I've started to write the login GUI. I followed the tutorial on MTA wiki but there is a problem, in my mind, on triggering the server event. And I want to play a mp3 file when the player join into the server, but it doesn't work...

This is the client code:

function createLoginWindow() 
    lblReportTxt = "Please LogIn." 
    wdwLogin = guiCreateWindow(504,255,407,175,"Welcome!",false) 
    lblReport = guiCreateLabel(15,27,70,16,lblReportTxt,false,wdwLogin) 
    btnLogin = guiCreateButton(316,146,80,20,"LogIn",false,wdwLogin) 
    lblUser = guiCreateLabel(85,62,61,17,"Username: ",false,wdwLogin) 
    lblPass = guiCreateLabel(85,106,61,17,"Password:",false,wdwLogin) 
    edtUser = guiCreateEdit(146,62,217,17,"",false,wdwLogin) 
    guiEditSetMaxLength(edtUser,20) 
    edtPass = guiCreateEdit(147,106,216,17,"",false,wdwLogin) 
    guiEditSetMasked(edtPass,true) 
    guiEditSetMaxLength(edtPass,20) 
  
 -- make the window invisible 
    guiSetVisible(wdwLogin, false) 
end 
addEventHandler("onClientGUIClick", btnLogin, clientSubmitLogin, false) 
  
addEventHandler("onClientResourceStart", getResourceRootElement(getThisResource()),  
    function () 
        --getGamemodeVersion() 
        welcomeSound = playSound("sounds/theme.mp3") 
        setSoundVolume(welcomeSound, 0.5) 
         
        -- create the log in window and its components 
        createLoginWindow() 
         
        -- output a brief welcome message to the player 
        outputChatBox("Welcome to My MTA:SA Server, please log in.") 
  
        -- if the GUI was successfully created, then show the GUI to the player 
        if (wdwLogin ~= nil) then 
            guiSetVisible(wdwLogin, true) 
        else 
            -- if the GUI hasnt been properly created, tell the player 
            outputChatBox("An unexpected error has occurred and the log in GUI has not been created.") 
            end  
  
        -- enable the players cursor (so they can select and click on the components) 
            showCursor(true) 
        -- set the input focus onto the GUI, allowing players (for example) to press 'T' without the chatbox opening 
            guiSetInputEnabled(true) 
    end 
) 
  
function clientSubmitLogin(button,state) 
    if button == "left" and state == "up" then 
        -- get the text entered in the 'username' field 
        local username = guiGetText(edtUser) 
        -- get the text entered in the 'password' field 
        local password = guiGetText(edtPass) 
  
        -- if the username and password both exist 
        if username and password then 
            -- trigger the server event 'submitLogin' and pass the username and password to it 
            triggerServerEvent("submitLogin", getRootElement(), username, password) 
  
            -- hide the gui, hide the cursor and return control to the player 
            guiSetInputEnabled(false) 
            guiSetVisible(wdwLogin, false) 
            showCursor(false) 
        else 
            -- otherwise, output a message to the player, do not trigger the server 
            -- and do not hide the gui 
            outputChatBox("Please enter a username and password.") 
        end 
    end 
end 

And this is the server code:

function loginHandler(username,password) 
    -- check that the username and password are correct 
    if username == "user" and password == "apple" then 
        -- the player has successfully logged in, so spawn them 
        if (source) then 
            spawn(source) 
            fadeCamera(source, true) 
            setCameraTarget(source, source) 
            outputChatBox("Connected!", source) 
        end 
    else 
        -- if the username or password are not correct, output a message to the player 
        outputChatBox("Invalid username and password. Please re-connect and try again.",source) 
        end          
end 
addEvent("submitLogin",true) 
addEventHandler("submitLogin",root,loginHandler) 

Thanks for your support.

clientside errors:

addEventHandler("onClientGUIClick", btnLogin, clientSubmitLogin, false)

should be in the createLoginWindow function

also: triggerServerEvent("submitLogin", getRootElement(), username, password)

should be: triggerServerEvent("submitLogin", getLocalPlayer(), username, password)

About the server side part, why are you checking is username is 'user' and pass is 'apple' ? Doesn't make any sense

Also.. spawn(source) ? spawn is no predefined function.. that would be spawnPlayer https://wiki.multitheftauto.com/wiki/SpawnPlayer

Thanks. It works. (spawn(source) is my personal function)

But now it doesn't work the playSound... How can I resolve this?

what about use this?

function play () 
welcomeSound = playSound("sounds/theme.mp3") 
setSoundVolume(welcomeSound, 0.5) 
end 
addEventHandler("onClientPlayerJoin", getRootElement(), play)
