Making Cars Go Bump in the Night

Finished another pleasant day at school, with one 3 hour canceled, leaving only one that started at 2:30pm.  It was kind of nice being able chill wth the ladylover and watch some Californication this morning instead.

Once at school, we continued to animate a car moving around the screen.  What I accomplished last week was keeping the car on the stage by cutting the speed to 0 when it hit the ed of the stage.  Now we are adding obstacles, which adds a new level of fun, both programming wise, and playwise.

It's pretty easy to moniter a hit between 2 objects, but each object is surronded by a an invisible box.  When Flash records a hit, it is when the two boxes overlap, but the eye, the objects are afair distance apart:


There is a trick out there to watch different coloured pixels overlap, that will take some research.

Another issue some people were having was removing a child from the stage.  We created the obstacle in an array of obstacles, but removing individual elements are turning oout to be a bit of a complicated pain.  Some more reasearch is required.

UPDATE:  Getting this error when I try to remove a child
                    ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
    at flash.display::DisplayObjectContainer/removeChild()
    at DocClass/HitObject()

Here is what my code looks like:
for ( var count:int = 0; count < NUM_OBS; count++ ) {
                 if ( car_mc.hitTestObject( obsArray[count] ) )
                 {
                     trace("HIT!!  KABOOM!!" );
                     obsArray[count].scaleX /= 2;
                     obsArray[count].scaleY /= 2;
                     //obsArray[count].play();
                     car_mc.speed = 0;
                     trace(obsArray[count].scaleX + " " + obsArray[count].scaleY);
                     if ( obsArray[count].scaleX < 0.125 )
                         removeChild( obsArray[count] );
                 }
}

Keeping in mind I am trying to manage an array of obstacles for a simple car game.
