Snake GUIs

Absence2 · March 2, 2012

Hello, I just found this wonderful resource, https://community.multitheftauto.com/index.php?p= ... ails&id=30

but I would like to expand it's uses by adding a few GUIs instead of commands.

So can I somehow add a GUI button and onClientGUIclick it triggers a commandhandler? ( /snake )

I've tried by adding so on onClientGUIclick it opens gameWindow but that failed and did not work at all.

Client:

size = 0.02 
direction = "right" 
lastdir = "right" 
pause = false 
started = false 
firstStart = false 
checkbox = {}

You may use

executeCommandHandler(commandName, thePlayer, [other arguments])

I don't get it,

how do I attach that^ to a onClientGuiClick / guibutton ?

Castillo · March 2, 2012

function clickHandler() 
    executeCommandHandler("snake") 
end 
addEventHandler("onClientGUIClick",myButton,clickHandler,false)

Absence2 · March 2, 2012

function clickHandler() 
    executeCommandHandler("snake") 
end 
addEventHandler("onClientGUIClick",myButton,clickHandler,false)

That did work on stopsnake but not /snake, but I suppose that is because they're in two different .lua files (same folder due), any suggestions? >.<

also I get this error: bad argument @ 'addEventHandler' [expected element at arguement 2, got nil]

something to worry about?

playSnake = guiCreateButton(0.05, 0.85, 0.20, 0.10, "Close", true, gameWindow) 
function clickHandler() 
    executeCommandHandler("snake") 
end 
addEventHandler("onClientGUIClick",playSnake,clickHandler,false)

That was an example, you can't use it like that, you must change "myButton" to your button argument.

Edited my post and I know, I'm not that big of a noob

EDIT: Wait a minute.. I fixed it, I had added the onguiclick outside the eventhandler.

Castillo · March 2, 2012

So it's working now?

Absence2 · March 2, 2012

So it's working now?

Yup, it's working, thanks for the help, both of you

I'm just worried about this one:

bad argument @ 'addEventHandler' [expected element at arguement 2, got nil]

Castillo · March 2, 2012

If the button is inside a function then you must add the event handler inside as well.

I am working on it, I guess I'm just slow..

If the button is inside a function then you must add the event handler inside as well.

And yes, you're right, sorry, I didn't realize that the error had dissapeared after correcting the first issue.

Castillo · March 2, 2012

There's nothing wrong on being slow.

You're welcome btw.
