CONNECT4: BASIC Tenliners Contest 2016 entry
My third entry in the 2016 10-line BASIC program contest is CONNECT4, a board game for two players. Once again I used the TurboBASIC XL Parser Tool to create the minimized BASIC file - the long lines version I submitted weighs in at 8 lines, putting in the extended line lengths category. I managed to get the the 120-character-per-line version created by the tool down to 11 lines, but frankly I feel kind of done with this one, so Im going to call it done rather than trying to squish it down to 120-character pure lines.
If anything, Id add to the program the ability to have a computer opponent, but I just dont think I can do it in the space I have left. At one point in this little programs development, when I had the board and the logic of identifying wins, I knew I had room to add player-missile graphics for the piece dropping, or a computer opponent, but not both. I went for the pretty graphical effect.
