Falling snow and collision detection. *New Flasher*

Good day, everyone.

I’m having a little trouble with a game I am creating. I created a “falling snow” effect from this tutorial. I then added a movie clip character (which I’ll call the bunny) at the bottom of the screen that is stationary along the _y axis and can move left or right along the _x axis.

The point of the game I am trying to create is to have the bunny at the bottom of the screen collect the falling snowflakes, adding score to a counter. However, I am having trouble detecting when the flakes touch the bunny. I have tried using the hitTest in every way I could think of but nothing works. Here is my code:

this.createEmptyMovieClip("canvas_mc",  10);

Interval = setInterval(addDart, 1000);

function addDart () {
    if(1 < 10) {
        var t:MovieClip = canvas_mc.attachMovie("dart1", "dart"+i, canvas_mc.getNextHighestDepth())
        i++;
        t._x = Math.random()*Stage.width;
        t._y = -50;
    }
}

Bunny:

onClipEvent(enterFrame) {
    if(Key.isDown(Key.LEFT)) {
        this._x -= 15;
    }

    if(Key.isDown(Key.RIGHT)) {
        this._x += 15;
    }
}

I’m basically asking where and how I should be using the hitTest(). I know the basics of collision detecting but for some reason this code is proving to be real difficult.

Thanks to anyone who helps out!
