I'm not trying to be a pain - but .... If your current code
stops working mysteriously when used inside a loop, it sounds
like at least one giant reason not to be entirely quite happy
with it. :)

In any case,

> def key_input  #Get arbitrary keyboard input
>     input = 0

>       if Input.trigger?(i)

>     end
>     if n > 0
>       input = n
>     end
>    return input
>   end 

The above just sets "input" equal to a number between
1 and 18, right?

If you need to make that loop last longer, you could
try adding a sleep() . . .  I'm only suggesting this
because I have no idea what you're trying to do,
really.  But for example:

     for i in 1..18
       if Input.trigger?(i)
         n = i
         break  # added
       end
       sleep(0.1)  # sleep 1/10 sec
     end


How is Input.trigger? itself implemented ?
