当我使用 Pygame 在 python 中达到某个点时显示“You Win”

分类：编程问答

如何解决当我使用 Pygame 在 python 中达到某个点时显示“You Win”

我想知道当我的玩家在游戏中达到 2000 分时，如何在游戏结束时显示“You Win”和图片。我还想在玩家与类 Reseta 碰撞时随机显示一个提示。下面是我目前的代码。请对我有耐心。谢谢！

解决方法

我为您创建了一个小例子。您唯一需要记住的是我的类 Game 中包含的方法 main_loop() 的用途（注释将帮助您理解它）。请记住，您添加了多个 while 循环，这些循环取决于您将要更改的变量以更改游戏状态。每个循环根据其目标打印出不同的内容。

对于要到达的点，只需创建一个不可见的 rect 并检查您的播放器 rect 是否与不可见的 rect 碰撞。如果是，请切换变量以进入另一个循环，该循环将打印出游戏以外的其他内容（在这种情况下，您可以打印出“您赢了”。

对于分数，您可以在玩家每次做某事时添加分数，并检查每一帧分数是否超过您设置的获胜分数。在这种情况下，只需切换变量即可更改游戏状态。

screen = pygame.display.set_mode((1000,500))

        super().__init__()

        # defining rect of the player
        self.rect = pygame.Rect((100,100),(100,100))
        self.color = (255,0)

    def move_right(self):

        self.rect.x += 20

    def main_loop(self):
        
        """The goal here is to create several loops. One will be for the main game loop that will contains

                        # defining just a key for the example
                        if event.key == pygame.K_d:

                # update the screen
                pygame.display.flip()

            while self.end_menu:

                for event in pygame.event.get():

                    if event.type == pygame.QUIT:
                        self.running = False
                        self.end_menu = False

                    if event.type == pygame.KEYDOWN:

                            self.end_menu = False

                # fills the screen in order to see the different states of the game
                screen.fill((255,0))

                # update the screen
                pygame.display.flip()


# initializing the class game
game = Game()

pygame.init()

# calling function `main_loop()` contained in the class Game (initialised as game)
game.main_loop()

pygame.quit()
,

当分数达到 200 时，有一种非常简单的方法可以让您在游戏中显示“You Win”。您需要一个变量来表示每次发生某些事情时都会增加的分数。首先，您必须通过执行 pygame.image.load(file name.png) 为“You Win”加载图像，然后您必须为图像的 x 轴和 y 轴分配变量（我使用 You_WinX 和 You_WinY 作为示例) 那么你可以简单地这样做：

if score == 2000:
     You_WinX = (location on x-axis)
     You_WinY = (location in y-axis)

这会做的是当分数达到 2000 的值时，“You Win”的图像将出现在屏幕上您想要的位置 (x,y)
