I thought you might be interested in my post about snapping to grids in actionscript 3. You can check it out here: http://www.murtensaerbi.be/blog/index.php/2008/08/08/actionscript-30-snap-to-grid/

I was wondering why the ball was shaking when I moved the mouse, but not far enough to make the ball move.
When I looked at this part:

ball.onPress = function () {
this.startDrag();
ball_move = true;
}

I got it. Why are you using this.startDrag?
You are setting the var ‘ball_move’ to ‘true’. And in the
ball.onMouseMove you are checking for that var to see if it’s true. If so, the ball is allowed to move.
So why use startDrag?
You can leave that part out

ball.onPress = function () {
ball_move = true;
}

And it will move more fluidly

By the way; I think this part:

this._x = _xmouse – _xmouse%size;

can be improved by adding half the gridsize to it:

this._x = _xmouse – _xmouse%size + size/2;

This makes the snapping feel a little better. Instead of having to move a hundered pixels to the right and having to move just 1 pixel to the left to make the ball move, you have to move it 50 pixels in either way to make it move if you add half the gridsize.

Same goes for the y ofcourse

Errors:
1.lineStyle(1,0×0000ff,100): x in the rgb hexadecimal
part has to be erased and rewritten.
2.The double quotes have to be replaced.

As well, the above code has ball clip created first.
The
createEmptyMovieClip(”ball”,this.getNextHighestDepth())
along with it’s mouse handlers have to be placed after the for loop that generates the grid.
Currently your code generates the grid and places circle behind it, this is due to getNextHighestDepth.

continues on same line as last piece of code from above:
