python - 制作 Tkinter Photoimage 使 python 程序崩溃

Question

我正在使用 tkinter 编写一个扫雷游戏，一切似乎都正常，但每次点击多次后 python 都会崩溃，我相信这是因为我为用于标记的“标记”添加了图像哪里有矿井。下面是绘制所有单元格的函数，每次移动/单击都会调用该函数。

def draw_cake_cell(canvas, row, col):
    # draws different cells on the board (blank cell, numbers, cake flags) 
    margin = 5
    cellSize = 30
    board = canvas.data['board']
    mask = canvas.data['mask']
    cake_count = canvas.data['cake_count']
    player_board = canvas.data['player_board']
    left = margin + col*cellSize
    top = margin + row*cellSize
    bottom = top + cellSize
    right = left+cellSize
    flag_img = PhotoImage(file="flag.gif")
    flag_label = Label(image = flag_img)
    flag_label.image = flag_img
    cake_img = PhotoImage(file = "cakeflag.gif")
    cake_label = Label(image = cake_img)
    cake_label.image = cake_img
    canvas.create_rectangle(left,top, right, bottom, fill = 'gray')
    if board[row][col] == -1:
       if canvas.data['isGameOver'] == True:
            canvas.create_image((left+right)/2,(top+bottom)/2,image = cake_img)
    elif mask[row][col] == -2:
        canvas.create_image((left+right)/2,(top+bottom)/2,image = flag_img)
    else:
       if cake_count[row][col] > 0 and player_board[row][col] == 1:
            value = cake_count[row][col]
            canvas.create_rectangle(left,top,right,bottom, fill = 'white')
            canvas.create_text((left+right)/2,(top+bottom)/2 , text = str(value), font = ('Helvetica',12))             
       if mask[row][col] == -2:
            canvas.create_image((left+right)/2,(top+bottom)/2,image = flag_img)
       if cake_count[row][col] == 0 and player_board[row][col] == 1:
            canvas.create_rectangle(left,top,right,bottom, fill = 'white')

Answer 1

由于您使用的是 python3，因此 (left+right)/2 是 float，而不是 int。也许这就是问题所在 - 使用 (left+right)//2。
