    Migration from AS2 to AS3

    Hello,

    I am new here and thought I might could find some help here. I followed a tutorial to create a small race game, but it is in AS2 and I need to have it in AS3. Is there anybody who could help me? I am not very good in coding and would be happy with any kind of help.
    Thanks in advance

    Hi and welcome,

    just dropping off a HUGE code block and asking for someone to simply convert it to AS3 is a bit of a far fetched request, don't you think, given that it's your first post as well ? We would love to help you, but if you at least TRIED to convert it to AS3 first by yourself, and if you get stuck, then asked for our help, I'm pretty sure a lot more people would be willing to help you If you could at least provide us with an FLA file so that we may check if the game works or not, and then take it step by step from there -- that would be great

    Have a still nice day
    I am back, guys ... and finally 18 :P

    BRING BACK THE OLD DESIGN!! OR AT LEAST FIX THE AS TAGS

    Hello All,

    This is another good thread, worth visiting & Testing the codes, I still didn't test them; "Load variables into array" Using three diffrent methods, find it on the following link:

    http://www.bokelberg.de/actionscript/28.html

    Best regards!

    P.S. Sorry this was posted here by mistake.

    I think we have only few minutes to edit or remove a reply...

    And this is flashkit, not google plus +1 -_-
    Already mastering AS3. It was so fun. Now into Javascript and PHP and all its libraries

    "I am not very good in coding" Then "get very good in coding". How? Learning Actionscript 3.0, not pretending that someone convert your codes, and copy pasting games from the internet. I don't think you will learn that way. Adobe has many tutorials, and explains the methods, classes, properties, events, etc. A great advice from someone that was a beginner once, and decided start reading and testing A LOT to gain knowledge and experience.

    You don't really have to do that. Another option would be to hire someone who already is very good. I mean, you don't get to drive when you are not very good at driving, do you. Or you do not cook, when you are not very good at cooking. You call taxi, and you dine at restaurant.
    who is this? a word of friendly advice: FFS stop using AS2

    I pay taxi if i afford it, i go restaurant if can pay for it.
    I like drive and good at but have no car.
    I cook well but want eat out sometime.
    I want learn sometime but not have time.

    just a few

    angle help maybe, good coder skill list in sig

    Y'all got good points imo, lol. But from the looks of it, the OP seems to have disappeared without a trace, so converting that to AS3 now would be meaningless... at least I was willing help, but OP was asking for too much.

    To add to you guys' "chain" of advice -- sometimes you just ain't got what it takes to learn how to drive or how to cook no matter how many times you try. That's when you resort to help from others, most likely close friends, 'cause I'm sure no stranger would drive to x destination or cook a meal y for you, unless that person's heart is of gold. Just my 2 cents, lolz
    I am back, guys ... and finally 18 :P

    but there must be something you're good at, no? and by doing that you're supposed to earn moneys to afford taxi rides and fine dinners. or else, your life is going to be very sad

    true, but not every talent is of "value" in today's world. No matter how amazing you're at one specific thing, if it doesn't sell, your life is unfortunately going to be sad. But then again:
