Scratch

Blue? I don't understand.

this website www.teach-ict.com shows you how to make pong, but then you will have to figue out the other things you will have to figue out your self.

I have an idea for the power up its:

 when gf clicked
switch to costume [no powerup] //or what ever you want to call it.
forever
     if <touching [powerup]?> //again, you can call it what you want.
         switch to costume [poweruped] //you know the drill.
         set [speed v] to [10]
    end
end

when gf clicked
set [speed v] to [10]
forever
    if <key [up arrow v] pressed?>
         change y by (speed v)
    end
    if <key [down arrow v] pressed?
         change y by ((speed) - ((2)*(speed))
    end
end
