Hello everyone

i don't know how i can use the events from SG craft.
I hope anyone can help me and show me a little example.

sgDialIn, source, remote address
sgDialOut, source, remote address
sgChevronEngaged, source, chevron number, symbol
sgStargateStateChange, source, new state, old state
sgIrisStateChange, source, new state, old state

thanks =)

Are you having trouble with these events, or events in general?

I guess start here.

Well when setting values you would use a single =, 2 is used for checking to see if two things equal the same thing.

These are events not functions. Events are fired based upon things such as a key being pressed or a mouse being clicked on the screen.

sgDialIn, source, remote address - An incoming connection has been initiated

sgDialOut, source, remote address - An outgoing connection has been initiated

sgChevronEngaged, source, chevron number, symbo - A chevron has been engaged during dialling

sgStargateStateChange, source, new state, old state - State of stargate has changed

sgIrisStateChange, source, new state, old state - State of iris has changed

sgMessageReceived, source, arg, … - A message was sent from the connected stargate using the sendMessage method



If you wanted to see what/when a event is fired you will want to use event,arg1,arg2,arg3,arg4 = os.pullEvent()
The args will equal the value of what follows the event in the table above respectivly.

edit: Sorry i copied and pasted a table, and when i hit post the format completely messed up.

local event = {os.pullEvent()}
if event[1] == "sgDialIn" then
  print( event[2] ) --# The source
  print( event[3] ) --# The remote address.
end

Just to clarify things… You don't "make" an event. An event happens when a user does something.

The code Dragon posted waits for a user to dial an address. (or so I assume, since I've never used SG craft)

Hello

I have a new problem…

my code ist not working with two event in one function…


while true do
local event,side,x,y = { os.pullEvent() }
if event[ 1 ] == "monitor_touch" then
if x == 2 and y == 3 then
    kai()
elseif x == 2 and y == 4 then
    nether()
  elseif x == 2 and y == 5 then
	 dark()
   elseif x == 2 and y == 10 then
	  sg.openIris()
   elseif x == 2 and y == 11 then
	  sg.closeIris()
   elseif x == 2 and y == 12 then
	  sg.disconnect()
	  monitor.setCursorPos(14,3)
	  monitor.write("	 ")
	  monitor.setCursorPos(14,4)
	  monitor.write("	 ")
	  monitor.setCursorPos(14,5)
	  monitor.write("	 ")
elseif event[1] == "sgDialIn" then
  print( event[2] ) --# The source
  print( event[3] ) --# The remote address.
    end
   end
  end

thanks for help =)

You are defining the table "event" as well as declaring "side", "x", and "y" as nil… Try using event[ 2 ] as side, event[ 3 ] as x, etc.

You also misplaced an end statement - consider cleaning up your indentation.

while true do
	local event = { os.pullEvent() }
	if event[1] == "monitor_touch" and event[3] == 2 then
		if event[4] == 3 then
			kai()
		elseif event[4] == 4 then
			nether()
		elseif event[4] == 5 then
			dark()
		elseif event[4] == 10 then
			sg.openIris()
		elseif event[4] == 11 then
			sg.closeIris()
		elseif event[4] == 12 then
			sg.disconnect()
			monitor.setCursorPos(14,3)
			monitor.write("        ")
			monitor.setCursorPos(14,4)
			monitor.write("        ")
			monitor.setCursorPos(14,5)
			monitor.write("        ")
		end
	elseif event[1] == "sgDialIn" then
		print( event[2] ) --# The source
		print( event[3] ) --# The remote address.
	end
end

The "event" variable ends up pointing to a table, which is basically a collection of data. All the data returned by os.pullEvent() goes into that table.

So if you do this:

local myEvent = {os.pullEvent()}

… then if the event that comes back is a monitor touch, then the table will look like this:

myEvent[1] = "monitor_touch"
myEvent[2] = side of the monitor
myEvent[3] = x position of the touch
myEvent[4] = y position of the touch

… but if the event is a timer, then it will look like this:

myEvent[1] = "timer"
myEvent[2] = id number of the timer

… and if the event is a Stargate state change, it might look like this:

myEvent[1] = "sgStargateStateChange"
myEvent[2] = source
myEvent[3] = new state
myEvent[4] = old state

The wiki page for os.pullEvent() shows you the layout for all events you might encounter in vanilla ComputerCraft.

Sorry, not quite sure what you mean by this. Can you show an example of how you think you might code it?

Ah this is cool, now i think i understand the event code..i hope it :)/>

This is a smal part from the code i have two different commands. One for open and one for close..my question is, can i this make smaller.

Now:
			   
elseif event[4] == 17 then
sg.openIris()
elseif event[4] == 18 then
sg.closeIris()

i would like this:
			   
elseif event[4] == 17 then   <---- First position
sg.openIris()
elseif event[4] == 17 then   <---- Same position how the first
sg.closeIris()

Assuming the commands here are accurate, you should be able to do something like this:

elseif event[4] == 17 then
  local state = sg.irisState()

  if state == "Closed" or state == "Closing" then
    sg.openIris()
  elseif state == "Open" or state == "Opening" then
    sg.closeIris()
  end
elseif ...
