Scratch

I was working on a pong game, and the script I have works about the first 20 times it falls, then I have to manually click the green flag (although I have something broadcasting the green flag)

The first script:

when gf clicked

go to x: (0) y: (0)
set [xv v] to [0]
set [yv v] to [0]
forever  

change [yv v] by (-0.3)
set [xv v] to ((xv) * (0.99))
change x by (xv)
if <touching [edge v]?> 

set [xv v] to ((-0.5) * (xv))
if <(x position) > [0]>

set x to (230)
else

set x to (-231)
end

end

change y by (yv)
if <(y position) < [-129]> 

set [ystoragevar v] to (y position)
set y to (-128)
if <touching [Paddle v]?>

point towards [Paddle v]
turn ccw (180) degrees
change [xv v] by ((8) * ( [sin v] of (direction)))
set [yv v] to ((8) * ( [cos v] of (direction)))
else

set y to (ystoragevar)
end

end

if <touching [edge v]?> 

broadcast [meh v]
stop script
end

end

when I receive [meh v]

broadcast [scratch-startclicked v]
wait (0.3) secs
