Multiple functions under the same DoClick button....

[Blakestr]

I'm still learning... I'm trying to get the button to do a different function each time (progressive)...I only need 3 times really

                     button2pressed = 0
                                
                                Button2.DoClick = function ()
                               
                               
                                if button2pressed = 0 then do (BroadcastLua(surface.PlaySound("sound1.wav")))
                                
                                print ("button pressed once")
                                button2pressed = 1
                               
                                elseif (button2pressed == 1) then
                               
                                do (BroadcastLua(surface.PlaySound("sound2.wav")))
                               
                                print ("button pressed twice")
                               
                                button2pressed = 2
                               
                                else do (BroadcastLua(surface.PlaySound("sound3.wav")))
                               
                                print "Button pressed 3 times, resetting"
                                button2pressed = 0
                               
                               
                                end
                                end

I'm sure its a syntax issue like that...any advice?

[whitestar]

the "do" is only for loops, remove it.

Removed it but the entire script won't even load but I can't find error messages to start down issue...

                                end

Let's start by fixing the indentation and that if-then syntax

button2pressed = 0

Button2.DoClick = function ()
	if button2pressed = 0 then
		BroadcastLua(surface.PlaySound("sound1.wav"))
		print ("button pressed once")
		button2pressed = 1
	elseif button2pressed == 1 then
		BroadcastLua(surface.PlaySound("sound2.wav"))
		print ("button pressed twice")
		button2pressed = 2                      
	else
		BroadcastLua(surface.PlaySound("sound3.wav"))
		print "Button pressed 3 times, resetting"
		button2pressed = 0   
	end
end

Now, BroadcastLua accepts a string, and sends that string to clients to be interpreted as Lua code. However, you have not wrapped it up into a string. It will instead attempt to run the code on the server (which won't work) and send the result to clients.

button2pressed = 0

Button2.DoClick = function ()
	if button2pressed = 0 then
		BroadcastLua('surface.PlaySound("sound1.wav")')
		print ("button pressed once")
		button2pressed = 1
	elseif button2pressed == 1 then
		BroadcastLua('surface.PlaySound("sound2.wav")')
		print ("button pressed twice")
		button2pressed = 2                      
	else
		BroadcastLua('surface.PlaySound("sound3.wav")')
		print "Button pressed 3 times, resetting"
		button2pressed = 0   
	end
end

[del]This will probably work[/del], but it can be done better.

button2pressed = 1

local soundlist = {
	'surface.PlaySound("sound1.wav")',
	'surface.PlaySound("sound2.wav")',
	'surface.PlaySound("sound3.wav")'
}

Button2.DoClick = function ()
	BroadcastLua(soundlist[button2pressed])
	button2pressed = button2pressed + 1
	if button2pressed > 3 then
		button2pressed = 1
	end
end

Now it uses a table to look up the appropriate string to send to clients. BUT WAIT! We aren't done yet

Button2.pressed = 1

local soundlist = {
	'surface.PlaySound("sound1.wav")',
	'surface.PlaySound("sound2.wav")',
	'surface.PlaySound("sound3.wav")'
}

function Button2:DoClick()
	BroadcastLua(soundlist[self.pressed])
	self.pressed = self.pressed + 1
	if self.pressed > 3 then
		self.pressed = 1
	end
end

Now it's more object oriented. I could keep going, but I think I'll stop here. It still needs more networking.

[whitestar]

its because you set button2pressed always to 0 upon pressing, define it as a local var outside the doclick.

How do you even fire the DoClick event of a button on the server's side?

Why do you always use "DO" followed by parentheses after a statement?

Very true, wasn't even thinking about that. Got caught up in fixing the bad syntax.

So what you will actually want to do, is use a console command or a net message to send it to the server, and have the server broadcast it to clients.

Explain what exactly you want. BroadcastLua doesn't seem ideal here, and usually never is anywhere. By the look of it you'd be better off using net messages and net.Broadcast

This is a special situation. I need that sound heard by everyone on the server. I am not worried about latency or security whatsoever. BroadcastLua seems to be the simplist but I can't get this If statement to work...

[Jcw87]

Ok, I have a little more time now.

Let's start with where I left off.

Button2.pressed = 1

local soundlist = {
	'surface.PlaySound("sound1.wav")',
	'surface.PlaySound("sound2.wav")',
	'surface.PlaySound("sound3.wav")'
}

function Button2:DoClick()
	BroadcastLua(soundlist[self.pressed])
	self.pressed = self.pressed + 1
	if self.pressed > 3 then
		self.pressed = 1
	end
end

So, you need to understand how the Lua states in Garry's Mod works. There are 2 separate Lua environments, the server, and the client. The server runs the server Lua state (obviously) and every client has its own client state. To get information from one state to another, you have to use networking. In this case, you have a Derma menu that you want to have play a sound for all clients. That means you have to tell the server about it, and then the server has to tell all the clients about it. Furthermore, you will want some kind of authentication on the server, so that some random jackass doesn't start abusing your sound player.

Client

Button2.pressed = 1

local soundlist = {
	"sound1.wav",
	"sound2.wav",
	"sound3.wav"
}

function Button2:DoClick()
	-- Start a network message with a name.
	-- This name will be used on the server to call the correct handling code.
	net.Start("MyRequestSound")
	-- Write the name of the sound you want to play.
	net.WriteString(soundlist[self.pressed]))
	-- Send it to the server
	net.SendToServer()
	self.pressed = self.pressed + 1
	if self.pressed > 3 then
		self.pressed = 1
	end
end

-- After the server receives your request to play the sound, it will tell clients to play it.
-- Handle that here
net.Receive("MyPlaySound", function(len)
	local soundname = net.ReadString()
