I found this highway car racing somewhere else, I need it to be in As2 or the same type, anybody who got it ?

package

    private const resY:int = 320;
    //Line of the player's car.
    private const playerLine:int = 8;
    //All the road lines will be accessed from an Array.
    private var zMap:Array = [];
    private var lines:Array = [];

    private var rx:Number; //Each line's x position
