ok so i have made an pong game in flash. or im trying to xD.  
but i need help on how to get the ball to move from on side to the other and if the paddle is in the way it bounces back can you help me??

the paddle moves up and down really fast, im calibrating it all the time to make it move smoothly and i cant upload the new version all the time . thats why the paddle is wierd in this swf file.

(when this is finished im gonna give you the code to it.)

1. name the ball mc to ‘ball’
2. if the code is not on the same level as the ball use path (like \_root.ball instead of ball when ball is on the stage)
3. make sure the code runs continously (like inside an event handler)

</div>

if (ball.\_x\<Number(leftpaddle.\_x+leftpaddle.\_width+ball.\_width/2)){  
if (ball.\_y\>Number(leftpaddle.\_y-ball.\_width/2) and ball.\_y\<Number(leftpaddle.\_y+leftpaddle.\_height+ball.\_width/2)){  
//hit  
goLeft=false  
}  
}  
if (ball.\_x\<leftpaddle.\_x-ball.\_width-10){  
//the ball is out  
}

the code still needs some polishing tough
