It's not telling me where the error is, it just says there is a error. Help?

It doesn't run at all and doesn't give you the line number?

Btw, your pull event won't work, the key event returns keycodes, not char's


local e,key = os.pullEvent( "key" )
if key == 2 then

This won't trigger when you press 2

local e, key = os.pullEvent("char")
if key == "2" then

That will

It does run but it doesn't give me a line number. my pull event did work. It said its a problem in rednet

If I have to take a stab at it. I'd say its the rednet.send (Hostname,…) in drawScene()

That's defined out in the script's scope as local and you're trying to access it in a function. I don't believe that carries across that scope like one might expect.

Now its 2am here and I've been using lua for a grand total of like 5 days… but I'd say that's your problem and you might consider passing hostname up the stack as a parameter.

Just my 2cents. :(/>/>
