First things first...get the code off of the balls
Create an actions layer in the first frame of the movie.
a good first approach would be to write the flow of the game in english first
all code lives in actions field in the _root level
ball flies
if blocked mylabel.text = "good work"
my_counter add 1 to good counter
check to see if game is won
if gameover
send out the dancing girls
Zero out the variables so game can start over
else
add one to bad counter
check to see if game is over
if gameover
send to hall of shame
Zero out the variables so game can start over
end
now with what ever you are using to block the ball you will be checking for a collision between your cursor and the ball
I would imagine that you would limit the blocker to move ment on the _x axis only or limited _y axis, another thought would be you probably want the balls going to random areas. I would also assume you are planning to animate the balls and the blocker with AS. To do this I would suggest using the Fusekit Framework. http://www.mosesSupposes.com.
You shouldnt have to draw many animations by hand. if so they should be encapsulated in thier own movie clips.
you could potentialy create this game in just a few code blocks.
