Need help with waiting for multiple events

Here's the gist…
I'm trying to make a security system with a forcefield. the outside uses a terminal that needs to be unlocked with a password, while on the inside, I use a touch screen I activate to send off a rednet message to the first machine.
I've tried using a method from this forum (http://www.computerc...ultiple-events/). However, it doesn't work on the first conditional statement, only the second (I've marked it in the code).

I hope you understand what I mean, and if you can help me with this, I'll be forever thankful.

  a = "Access Granted",

  c = "Invalid"

function setText(color, x, y)

local key2 = false

We're still running 1.4.7, as we are using the mindcrack pack from FTB. Also, the second event does fire, just not the first one :/

So, when it is sitting at "press any key to continue", it fails to see any rednet messages come in? You've used debug prints to verify that it is receiving the events, but that the if statement isn't catching them? I'd suggest using some debug prints to verify exactly what's going on if you haven't already done so.

This is what's so strange.. I did use a debug print on line 18(just below term.clear() ), and it showed up after I sent the message, but nothing happened to my forcefield.

I know the message I send is correct, because I sat up a second computer to print out the message it recieved after I broadcasted it (just in case), and it printed the correct message.

I also know that all the wiring is correct, because when I use the "char" event in the second loop, it turns the forcefield on and off.

edit: got the line wrong :P/>

What did debug prints in the if statements turn up, as to whether it thinks it's turning the redstone on/off?

It's as if it loops around without doing anything, untill it comes back around to "press any key to continue".

I'm going to try putting in some more of them.. maybe I'll come up with something

wow….. I have no idea what happened, but I put in debug prints everywhere, and suddenly everything just worked :S I'm really confused now..
I suppose it might have something to do with lag or something with the server in some way, but I'm not sure.

Thanks for the reply guys!

Please provide reliable reproduction instructions to create a scenario in which rednet_message events do not fire under conditions in which they should. If you can provide those, please post that in Bugs. If you cannot, you need to stop posting that rednet is deprecated, or that rednet_message events don't work correctly, or that it's buggy. All of that is incorrect information, which is unacceptable in answer posts in Ask a Pro.

to help, here are the conditions on which rednet_message events fire:

* rednet.open() was called on the side the modem_message came from.
* the message came on the computer's id frequency or on the broadcast frequency.

… and that's the whole list.

opening those frequencies directly through the modem will not cause them to fire. I have seen no evidence of inconsistency in this behavior, so I am guessing you perceived inconsistency because you weren't aware of exactly what these conditions were.
