I have been working on creating a 3 dimensional tic tac toe.
First I wanted to be able to print/present the board. As of right now I don’t have the skills to be able to create a 3-d animation, so this will still be printed 2-d in the terminal. That means I need to print 3 separate boards.
Initially I wanted to print the boards separate horizontally like so:
#_( 1 | 2 | 3 10 | 11 | 12 19 | 20 | 21
4 | 5 | 6 13 | 14 | 15 22 | 23 | 24
7 | 8 | 9 16 | 17 | 18 25 | 26 | 27)
But after trying and thinking, I decided to make it easier on myself and do it vertically like so.
#_(
1 | 2 | 3
4 | 5 | 6
7 | 8 | 9
10 | 11 | 12
13 | 14 | 15
16 | 17 | 18
19 | 20 | 21
22 | 23 | 24
25 | 26 | 27
)
I am now not sure if there is a difference in style but let me show you why it was easier to do it this way.
(defn separate [row]
(str/join " | " row))
(defn display [grid]
(->> grid
rows
(map separate)
(str/join "\n")))
This was the previous function I had to present the original 2-d board, either for the 3x3 or 4x4 board. rows was a way to separate the rows based on the square root of the total number of elements.
I gained inspiration from that and was able to conjure my own idea to create a new grid in a similar manner.
So i did this:
(defn separate-3-3 [grid]
(partition 9 grid))
(defn display [grid]
(->> grid
rows
(map separate)
(str/join "\n")))
(defn display-3-3 [grid]
(->> grid
separate-3-3
(map display)
(str/join "\n\n")))
I decided to take the display format, use it again. You can see it in display 3-3, it is the same format instead of rows and separate, I placed separate-3-3 which would partition it into its separate faces. And since display was already a function I was able to map through it once again.
I think this was a nice and clever solution to this problem.
I am now stuck on the winning conditions but that maybe for another time.
Best,
