Python Tkinter战舰游戏完成玩家2回合后无法切回玩家1求助

问题根源 #

1. 界面组件未隐藏：切换玩家界面时，未将当前显示的棋盘按钮隐藏，导致新界面按钮被旧按钮覆盖，视觉上无法完成切换。
2. 按钮列表创建冗余：buttons1和buttons2的创建多了一层for i in range(2)循环，生成了20行按钮（远超棋盘需要的10行），属于无效代码且易引发逻辑混乱。
3. 重复创建next按钮：每次切换界面都会新建一个next按钮，旧按钮仍存在于界面中，可能导致事件冲突或视觉遮挡。

修复后的代码 #

import tkinter as tk

window = tk.Tk()

ship_sizes = [5,4,3,2,2]
board_size = 10

# 初始化玩家棋盘
board1 = [[0 for _ in range(board_size)] for _ in range(board_size)]
board2 = [[0 for _ in range(board_size)] for _ in range(board_size)]

# 为玩家1随机放置战舰
for ship in ship_sizes:
    while True:
        x = random.randint(0, board_size-1)
        y = random.randint(0, board_size-1)

        if orien == 'hor' and x + ship <= board_size:

关键修改点 #

• 新增hide_all_boards函数：切换界面时先隐藏所有棋盘按钮和旧的next按钮，彻底避免组件重叠问题。
• 修复按钮列表创建循环：移除多余的for i in range(2)循环，确保buttons1和buttons2仅生成10行（匹配棋盘尺寸）。
• 全局next按钮管理：将next按钮设为全局变量，每次切换时先隐藏旧按钮再创建新的，避免重复创建引发的冲突。
• 优化点击逻辑：击中后将棋盘对应位置设为1，防止重复点击同一位置时重复触发状态变化，同时简化了原代码中冗余的按钮属性设置操作。
