• How can I use Action Script 3.0 to make random placed Symbols fly by?

  - by William Calleja

  I'm trying to make a simple animation with Flash CS4 and Action Script 3.0 to make a number of Symbols fly by from right to left constantly. What I want is that once a symbol has reached the end of the screen it is destroyed and another one is placed at the start position. I intend to give each symbol a random speed and create a random symbol each time one is 'destroyed'. Any clues where I can start?

  - by user607057

• How to get number of entries in a Lua table?

  - by romkyns

  Sounds like a "let me google it for you" question, but somehow I can't find an answer. The Lua # operator only counts entries with integer keys, and so does table.getn: tbl = {} tbl["test"] = 47 tbl[1] = 48 print(#tbl, table.getn(tbl)) -- prints "1 1" count = 0 for _ in pairs(tbl) do count = count + 1 end print count -- prints "2" How do I get the number of all entries?

• How to display a very long page like dzone.com?

  - by user360529

  Hi, If you ever visit dzone.com you'll notice that all the posts appear on 1 page only. When we scroll that page down, older posts will be added to the end of the page (and maybe some posts at the beginning of the page but outside the view port will be removed). My questions are: - how to know if the user scrolls down/up with javascript/jQuery? - how to know if the user is at the top of the page (they click Ctrl + Home)? Thank you.

• Find all occurrences of a substring in Python

  - by cru3l

  Python has string.find() and string.rfind() to get the index of a substring in string. I wonder, maybe there is something like string.find_all() which can return all founded indexes (not only first from beginning or first from end)? For example: string = "test test test test" print string.find('test') # 0 print string.rfind('test') # 15 #that's the goal print string.find_all('test') # [0,5,10,15]

  Could somebody please explain why the variable named foo remains true in the code below, even though it's set to false when the method is called?
