How set for collision with other balls while ball is growing?

问题

I'm trying to stop grooving of ball and drop to bottom of the stage when it's hit to the other balls.But I can't. I tried set distance but it's not worked.

I add a picture of the game

And my code

Enemy balls(green) touch each other fine.But not touch circle make by the mouse.Balls touch to black balls but not seeing touched massage.The touch message appear only when touch the mouse arrow.
