I need some Gui help

[carloxhunter]

Hi im noob on scrpting, so probably will be a noob question for you, but anyway, i need help, and, im learning so here is:

Im modyfing a PUBLIC script, its a Basic login pannel and, as it hadnt Guest botton, i thought would be good idea if i add it by myself,so i tried addeding to client.lua file the next:

guestb["guests"] = guiCreateButton(140, 178, 70, 30, "Guest", false, loginWindow["mainWindow"]) 
addEventHandler("onClientGUIClick", guestb["guests"], guest32, false) 
  
function guest32(button,state) 
        if button == "left" and state == "up" then 
            guiSetInputEnabled( false ) 
            guiSetVisible(loginWindow["mainWindow"], false) 
            showCursor(false) 
        end 
end 

pd: loginWindow["mainWindow"] is the window to hide.

i really dont know what to do, atleast i tried, maybe i have to do something on server,lua??, any help?

This might be the problem: you must declare handler functions before the event handlers they will be used for.

guestb["guests"] = guiCreateButton(140, 178, 70, 30, "Guest", false, loginWindow["mainWindow"]) 
  
 function guest32(button,state) 
        if button == "left" and state == "up" then --Maybe you should use state == "down" instead 
            guiSetInputEnabled( false ) 
            guiSetVisible(loginWindow["mainWindow"], false) 
            showCursor(false) 
        end 
end 
addEventHandler("onClientGUIClick", guestb["guests"], guest32, false) 

As a note, when you test your scripts, bother using the command /debugscript 3, to check where do said errors come from.

This might be an exception though, since addEventHandler's sources are never shown.

If it still doesn't work, then post your results with that command I just said, plus your full codes.

i repeat all code isnt mine just part im getting errors

Well i tried what you told me and still doesnt work, debugscript Results:

"ERROR":loginedited\client.lua:113:attempt to index global 'guestb' (a nil value)"

(i tried also use Hidewindow function defined before and same result, nothing) full code:

local serverInfo = "blahblah" 
function centerWindow(center_window) 
    local screenW,screenH=guiGetScreenSize() 
    local windowW,windowH=guiGetSize(center_window,false) 
    local x,y = (screenW-windowW)/2,(screenH-windowH)/2 
    guiSetPosition(center_window,x,y,false) 
end

"ERROR":loginedited\client.lua:113:attempt to index global 'guestb' (a nil value)"

That error occurs when you try to insert values into non-declared tables.

To fix it, either change the name of your button to something without the brackets [ ], or add this line before it:

guestb = { } 

This is declaring a table. You can read more about tables and related at the Lua wiki.

If you're familiar with arrays, it's similar but easier to use.
