按照教程創造了一個2048的遊戲，但是不知道為什麼遊戲結束(輸了)會導致系統崩潰，必須強制關閉，求幫忙(已解決)

最佳解答

我沒寫過 python 也不知道這遊戲在玩什麼
不過這程式的問題是在 add_new_tile()
當畫面上 16 個格子都有大於 0 的數字存在時，主程式 121 那個 while 迴圈就會無限巡迴

該處理的可能也不是 add_new_tile() 而是遊戲結束的判斷條件
也可能兩個都要處理

看看 game_over(self) 的邏輯對不對吧，如果格子填滿就要判斷遊戲是否結束，那 add_new_tile() 就不用修，要修的是判斷條件

因為是看著教程寫的,所以邏輯上應該不會有問題。我覺得可能是哪裡遺漏了什麼，我再看看把

rainbowrain iT邦新手 2 級 ‧ 2022-06-20 12:34:17 檢舉

在 121 行那個 while 迴圈前面加個判斷式就不會變成無窮迴圈

    def add_new_tile(self):
        row = random.randint(0,3)
        col = random.randint(0,3)
        if any(0 in row for row in self.matrix):
            while(self.matrix[row][col] != 0):
                row = random.randint(0,3) 
                col = random.randint(0,3)
        self.matrix[row][col] = random.choice([2,4])

你如果是複製貼上，那表示教學本來的程式就有問題。

如果是自己看著打，就可能就是你打錯

例如 210 行

        elif not any(0 in row for row in self.matrix) and not self.horizontal_move_exists() and not self.vertial_move_exists:

self.vertial_move_exists 就沒加括號

解決的ㄟ
加括號之後ww

rainbowrain iT邦新手 2 級 ‧ 2022-06-20 14:00:50 檢舉

你貼上來的程式碼只解決第 210 行沒加括號的問題還是一樣會進無限迴圈，原因我上面講了就是 add_new_tile

因為 16 格都有數字不等於會 gamer over，但 add_new_tile 已經找不到等於 0 的格子，所以跳不出迴圈

而且那個判斷方式也不好，如果今天不是 4x4，是 16x16 甚至更大的話，找 0 就要浪費很多時間

codenewww iT邦新手 5 級 ‧ 2022-06-20 15:10:08 檢舉

那應該就是教程的問題了，那個判斷方式我是參考她的
