Hi,

Just wondering if this is the right way to use the rednet event:

  rednet_message, id , msg, dist = os.pullEvent()
  print(id, msg, dist)

If so im getting problems with this...

Or how do you use it?

[OmegaVest]

More or less, that should work. What kind of problems are you having with it?

Unless you are only trying to pull rednet_message, in which case you should do this:

emty, is, msg, dist = os.pullEvent("rednet_message")

Doesnt seem to work either (Better then what happened before though). I'm trying to use it in this:

function drawLines()
  term.clear()
  term.setCursorPos(1,1)
  paintutils.drawLine(1, 10, 50, 10, 128)
end

rednet.open("right")
red1 = paintutils.loadImage(red)
green1 = paintutils.loadImage(green)

while true do
  emty, id, msg, dist = os.pullEvent("rednet_message")
  print(id, msg, dist)
	if id == 3 then
	  if msg == "green" then
		drawLines()
		paintutils.drawImage(green1, 25, 10)
	  else
		drawLines()
		paintutils.drawImage(red1, 25, 10)
	  end
	else
	drawLines()
	end
end

Nope. rednet.receive() returns three args:

id, msg, dist = rednet.receive()

...Except he's using os.pullEvent, which in the case of rednet_message, returns 4 args, event, id, message and distance travelled.

And, again, you don't ever say what happens, kennyist. You say that it isn't working, but unless we know what it IS doing, we can't necessarily know how to help you.

With this:

function drawLines()
  term.clear()
  term.setCursorPos(1,1)
  paintutils.drawLine(1, 10, 50, 10, 128)
end
rednet.open("right")
red1 = paintutils.loadImage(red)
green1 = paintutils.loadImage(green)
while true do
  emty, id, msg, dist = os.pullEvent("rednet_message")
  print(id, msg, dist)

	if id == "3" then
	  if msg == "green" then
		drawLines()
		paintutils.drawImage(green1, 25, 10)
	  else
		drawLines()
		paintutils.drawImage(red1, 25, 10)
	  end
	else
drawLines()
end
end

At the moment im geting "paintutils:14: Expected string"

adding quotation marks onto the loadimage paramaters stops this, but then nothing shows up atall.

Yeah, the pull event is not working, this doesnt even show anything.

function drawLines()
  term.clear()
  term.setCursorPos(1,1)
  paintutils.drawLine(1, 10, 50, 10, 128)
end
rednet.open("right")
red1 = paintutils.loadImage("red")
green1 = paintutils.loadImage("green")
while true do
  emty, id, msg, dist = os.pullEvent("rednet_message")
  print(id, msg, dist)
end

I c the problem you have to use red1 = paintutils.loadImage("red") with "" for a name

rednet.open("right")

  else
	sleep(10)
	drawLines()
  end
end

the id shut not be inbetween ""

Before we go too far, where are the "red" and "green" images stored on the computer? They require absolute paths, just like the fs api.
