小游戏规则简介

实现

初始化游戏窗口

import sysimport pygame
width = 800height = 800#  初始化所有pygame模块pygame.init()# 创建游戏主窗口 width * heightwindows = pygame.display.set_mode((width, height))pygame.display.set_caption('兔子吃月饼！！')# 游戏循环while True:    # 给屏幕填充颜色    windows.fill((204, 204, 255))    for event in pygame.event.get():        # 判断事件是否是退出事件，是则退出        if event.type == pygame.QUIT:            # 先退出pygame窗口，再退出程序            pygame.quit()            sys.exit()    pygame.display.flip()

游戏逻辑

实现玩家类

class Rabbit:    """    玩家兔子类    """
    def __init__(self, top, left, height, width):        # 初始位置及大小        self.top = top        self.left = left        self.height = height        self.width = width        # 游戏人物的初始位置        self.rect = pygame.Rect(self.left, self.top, self.width, self.height)
        self.player_image = pygame.image.load('兔子.png')        self.player_stretched_image = pygame.transform.scale(self.player_image, (height, width))
        # 控制移动变量        self.move_left = False        self.move_right = False        self.move_up = False        self.move_down = False        # 每次移动的大小        self.MOVESPEED = 5        # 重量        self.weight = 5
    def move(self):        """        控制移动        :return:        """        if self.move_down and self.rect.bottom < height:            self.rect.top += self.MOVESPEED            self.rect.bottom += self.MOVESPEED        if self.move_up and self.rect.top > 0:            self.rect.top -= self.MOVESPEED            self.rect.bottom -= self.MOVESPEED        if self.move_left and self.rect.left > 0:            self.rect.left -= self.MOVESPEED            self.rect.right -= self.MOVESPEED        if self.move_right and self.rect.right < width:            self.rect.left += self.MOVESPEED            self.rect.right += self.MOVESPEED

实现月饼类

class MoonCake:    """    月饼类    """
    def __init__(self):        # 位置及大小        self.rect = pygame.Rect(random.randint(0, 750), random.randint(0, 750), 20, 20)        # 图像        self.moon_cake_image = pygame.image.load("./月饼/月饼{}.png".format(random.randint(1, 8)))
