Reversi有效移動檢查器

Question

我一直在做一個任務，需要我在matlab中重新創建reversi。

我已經達到了一個突破點，我無法弄清楚如何做一段代碼而不把它變成線性索引。

本質上我需要做的是找出一種方法來添加一個方向向量（即[-1; 0]垂直走向），我已經存在的game_state向量爲了找到它上面的數據。

function legal = legalMove() 
d_l = [0, -1]; 
d_r = [0, 1]; 
d_u = [-1, 0]; 
d_d = [1, 0]; 
d_ul = [-1, -1]; 
d_ur = [-1, 1]; 
d_dl = [1, -1]; 
d_dr = [1, 1]; 
directions = [d_l d_ul d_u d_ur d_r d_dr d_d d_dl]; 
valid_moves = zeros(8,8); 

for ci = 1:8 
    for cj = 1:8 
     if game_state(ci,cj) == 0 %check element = 0 before continuing 
       for count = 1:8 
        d = directions(count); 
        selected = 
        while selected == player_number * -1 %while the selected piece is of enemy type 

          %move as long as you find your opponents stones 
         if you found at least 1 opponent stone and you end up on your own stone 

         else 
         end 
        end 
       end 

     else 
     end 
    end 
end 
    end 

我的第二個問題之後，是實際的循環本身。 雖然我認爲可以使用while循環來確定是否保持當前的方向，但我似乎無法找到一種方法來自己做。

任何援助將不勝感激。

謝謝你的時間！

變化directions細胞陣列包含字符串：（！填空）

... 
directions = { 'd_l' 'd_ul' 'd_u' 'd_ur' 'd_r' 'd_dr' 'd_d' 'd_dl' }; 
... 

代碼會去這樣的事情。然後下一部分：

for count = 1:8 
    d = eval(directions{count}); 
    ti = ci+d(1); 
    tj = cj+d(2); 

    % Check if out of the board 
    ... 

    % Number of enemy pieces you went over 
    cnt = 0; 
    selected = gamestate(ti, tj) 

    % Move while going over enemy pieces 
    while selected == player_number * -1 
     ti = ti + d(1); 
     tj = tj + d(2); 
     selected = gamestate(ti, tj); 

     % Check if out of the board 
     ... 

     % Count pieces you went over 
     cnt = cnt + 1; 
    end 

    % Check if you moved over enemy pieces & whether you landed on your piece 
    ... 

end
