Hello all,

Im kinda being a n00b with rednet, so I was just wondering.

Is there a way to run a program that would just run something, while checking for a rednet message?
Kinda like this:

while true do
  if rednet == "Hello" then
    print("Hello!")
  end
  if rednet == "Bye" then
   print("Bye")
  end
  if not rednet then
    print("No message received")
  end
end

Thanks in advantage.

try something like this

while true do
  event, senderId, message = os.pullEvent()
  if event == "rednet_message" then
    print(message)
  end
end

Yeah use parallel api:

function yourFunction()
    -- blah blah code
end

function waitForMessage()
    while true do
	    e, senderID, message = os.pullEvent("rednet_message")
	    print(message)
	    return  -- use this if you want the program to stop when it gets a rednet message
    end
end

-- Main
parallel.waitForAny( yourFunction, waitForMessage ) -- waitForAny means it will stop when any of the functions returns, use waitForAll if you want it to only stop when all functions return

can do that too.

but threading isn't the solution to everything. using os events can be just as much, if not more powerful!

Hmmm... That is not exactly what I want, because I explained it wrong.

I kinda want a IRC system, where you can type, and send messages, but the computer will, in the meantime check if theres a new message, and print it.

EDIT: I just read remiX's program critically, aaand... Im still not sure if that if that does what I want, I'm gonna test!

You have 2 options here:

The not so flexible, but so much easiser parallel API

Or recoding a custom read that will accept a rednet message in between.

[theoriginalbit]

you could also have a variable that holds what the user has typed, and on key press event add the char pressed. then if the event is rednet add it to the messages table

[Doyle3694]

that is the second option I wrote about.

oh i thought you meant a custom read() lol

[Doyle3694]

yeah and that is exactly the meaning of what you wrote about... Anyways, back to topic!
