From: Rico Knoop on 26 Mar 2010 05:17 i'v bin programming for about 2 week now and just about completed http://pine.fm/LearnToProgram/ but for a change of pace i started something of my own but i cant seem to get my program to wait X-seconds for user input. basicly what i got is: input= "empty" input= gets.chomp if input == "empty" puts "no input" else puts input end all i want it to do is wait like 10 seconds and if there has bin no user input it should just continue with input= "empty" i feel like i'm missing something real simple thnx in advance -Bakakyoo- -- Posted via http://www.ruby-forum.com/.

It might depend on which operating system and/or Ruby version you are using. I tried the code underneath on Windows Vista, using the Ruby Windows versions, and Ruby. It works for me using Ruby 1.9 for Windows. But using Ruby 1.8.6 and using the JRuby 1.8 equivalent seemed to work, or rather not work, in the way you described in your latest post. Colin Bartlett |
