Random values not working

  You'll probably want to be using math.randomseed() to get the generator started somewhere new every time. You can use the system clock to provide it a value. For instance:
  
  math.randomseed(os.clock())
  
  That's just the time the program has been running. You might experiment with different timers until you get the result you're looking for. os.timer() might be a good one to try as well.

  @FlimFlamboyant if I put this in scene:init function, then wouldn't it always get the same number, because the programme has been running for zero seconds?

  Just running a quick test here shows that both os.clock() and os.timer() are putting out unique values every time I run the program, but it's close. It looks like os.time(), as mentioned in the other thread, is the best way to go, as it's just a straight-up clock for the OS itself, not a timer based on how long your app has been running.

  Thanks @FlimFlamboyant and @ar2rsawseen! I ended up using os.time for randomseed, because its is the only one that generates a different coordinate every time.
