Create a Flash Racing Game Tutorial – AS3 version

The porting of the most popular AS2 tutorials continues with a basic AS3 version of the Flash racing game script.

I said “basic” because it does not have all features, this time it covers only movement and collision detection because I want to add more features before polishing it.

In the detail, I am developing an artificial intelligence algorithm to include cars controlled by the computer.

Meanwhile, this is the main class

And this is car_mc class:

And this is the result

Play with arrow keys, and be prepared to race against CPU

    You could not have posted this at a better time. Yesterday I started converting you last tutorial to AS3 and I was going to work on it all day today and tomorrow. I am using it for a biofeedback application in a neuroscience lab.

    Thank you so much!!!!

    PS. What is your creative commons license for this? Can I use it for non-profit?

    You never disappoint us :) Are you going to make a tutorial like “Create a Flash game like Zelda” or something? I’m pretty sure that most of us want to know how to develop a good RPG game engine. And you my friend, are the best person to teach us :D. Pleeeease.

    Im planning on learning flash sometime and its interesting for me to look at this code, just to get a sense of how actionscript works. thanks :)

    Also, i have been using a program called scratch, which basically is for creating some very simple games, with very simple code. Quite a while ago, i made a game similar to this: http://scratch.mit.edu/projects/aonews/289090

    and just fyi, in case any of you where planning on looking at the code, you should know i made it a few years ago, and the code is rather redundant and could be simplified a lot. :)

    I got this error message:

    “Type was not found or was not a compile-time constant: ground_mc
    race.as line 8″

    Seems like should be another class called ground_mc?

    (sorry for my English and newbie question)

    I was messing around trying to add different tracks but the only way is for the track to be erased so how can we change the track without just erasing from the back ground and without the ground_mc

    Thx in advanced

    This is Really great. Is there a way to control the number of Laps? How could I make it 3 instead of 10?

    on December 1, 2011 at 9:18 pm

    Thanks for the great racing game. Could you post or email a description of what the different lines of code are doing like you did in the AS2 version?

    Hi, I have created a short animation storyboard and would like to incorporate this mini-game at the end (e.g. frame 2885), can it be done? If yes, how do I do it?

    GREAT Tutorial! i’m started to understand how to make as3 games… never thought that it will requires trygonometry though..

  35. Christoffer

    on January 24, 2012 at 6:52 pm

    Do you have a tutorial on how to make the laptimer in as3? Or is it very similiar to the as2 version?

    Otherwise, great tutorial. Thanks ;)

  36. Ben Reynolds

    on February 15, 2012 at 8:06 am

    I still regard this as one of the best, albeit simple, classic flash tutorials. Thanks for the inspiration!

  37. Luke Hill-Cottingham

    on May 17, 2012 at 6:25 pm

    Good tut, but how would i go about putting a menu in before the game starts?

    The idea is to, like the AS2 version, put a lap timer in and have a menu before hand to start the game.
    Yet i’ve made a menu and when i try to merge the two, it just plays up calling the class first(i think), is there anyway to call the class when i reach a certain frame?

    sorry for being a bit vague, new to this stuff.
