Fr Chris' notes on progress
Don will be working on a Note class that will know how to draw itself, based on the path chosen at its instantiation.
Nick needs to work on the keyboard input.. (paddle that is moved into one of four locations, and knows where it is. The applet then can see if a note is at the bottom, and ask the paddle is at the correct string location or not.
The song class may take a while to write, so maybe Suren & I can work on a class to make notes play a simple song like "Twinkle, Twinkle, Little Star"
Twinkle Twinkle
This song is familiar, only uses 6 (C,D,E,F,G,A) notes, and the rhythm is very uniform, so if we keep a frame counter, we can add a new note when ever we have a frame%tempo==0. We can either change so that there is six strings or assign more than one note to the same string.
C,C,G,G,A, A, G, (rest),
F,F,E, E, D, D, C, (rest),
G, G, F, F, E, E, D (rest),
G, G, F, F, E, E, D (rest),
C,C,G,G,A, A, G, (rest)
F,F,E, E, D, D, C, (rest),

KeyMovement
been working on the key movement and added a paddle class, having trouble getting it to appear on the Applet
Fr Chris' comments: needs some import statements, there is a bracketing issue in the actionPerformed(ActionEvent e) method, and p1 is never defined... I presume you want to do somthing in the init() method like " Paddle p1= new Paddle(); "

Fr Chris' Notes to Nick
The plan is to have Don work on the dots coming down the string, and Nick to work on the "paddle" end to catch the notes.
Looks like great progress Nick!
To Do:
- Find some nice sounds for a hit or a miss.
- keep score
