为什么计算机会生成这么多随机位置？

Question

我正在制作一个井字游戏，其中玩家与计算机对战。问题是，我编写了一个 rand() 定义，它仅在没有组合时调用，例如。玩家在 1x1 和 1x2 上没有 'X' 或者玩家在 1x3 和 1x2 上没有 'X'。然后计算机生成一个随机框，必须用 'O' 填充，但计算机会填充除 'X' 框之外的所有剩余 space。我需要计算机只填充一个随机 space，然后将 player.turn 变为“播放器”。请记住，我还没有完成 computer.defend().

这是我的代码：

os.environ['SDL_VIDEO_CENTERED'] = '1' # You have to call this before pygame.init()

求助，这件事困扰了一个月。谢谢

您的代码中有两个问题：

您在每次执行循环时都重新发送鼠标事件，而不是在它实际发生时重新发送。

为了解决这个问题，我将鼠标事件移到了事件循环中：

while True: #main loop
    for event in pygame.event.get(): # event handler
        if event.type == pygame.QUIT:
            pygame.quit()
            from sys import exit
            exit()
        if player.turn == "player":
            player.mouse(event)
    canvas.blit(bckgrnd, (0,0)) # drawing background
    arena()

    checkX() #draw X
    if player.turn == "computer":
        player.turn = computer.defend()
    checkO() #draw O
    pygame.display.update()

您正在引用 class comp 内部的局部变量 player.turn，而不是引用玩家的变量 class。

为了解决这个问题，我 return 计算机对象的 turn 变量并将其分配给玩家对象的 turn 变量：

    def defend(self):
        if self.places["1x1"] == "x" and self.places["1x2"] == "x":
            self.places["1x3"] = "o"
            player.turn = "player"
        elif self.places["1x1"] == "x" and self.places["2x1"] == "x":
            self.places["3x1"] = "o"
            player.turn = "player"
        elif self.places["1x2"] == "x" and self.places["1x3"] == "x":
            self.places["1x1"] = "o"
            player.turn = "player"
        elif self.places["3x1"] == "x" and self.places["2x1"] == "x":
            self.places["1x1"] = "o"
            player.turn = "player"
        elif self.places["3x1"] == "x" and self.places["1x1"] == "x":
            self.places["2x1"] = "o"
            player.turn = "player"
        elif self.places["1x1"] == "x" and self.places["2x2"] == "x":
            self.places["3x3"] = "o"
            player.turn = "player"
        elif self.places["1x2"] == "x" and self.places["2x2"] == "x":
            self.places["3x2"] = "o"
            player.turn = "player"
        else:
            player.turn = "player"
            self.rand()

        return player.turn

# inside the main loop:

if player.turn == "computer":
        player.turn = computer.defend()
