用python和pygame库实现刮刮乐游戏
首先，确保你已经安装了pygame库。如果没有安装，可以通过以下命令安装：
pip install pygame
示例有两个。
一、简单刮刮乐游戏
准备两张图片，一张作为背景bottom_image.png，一张作为刮开的图片top_image.png：
请将bottom_image.png和top_image.png图片文件与游戏代码文件（.py文件）放在在同一目录下。
以下是简单刮刮乐游戏的代码：
import pygame
import os
# 初始化pygame
pygame.init()
# 设置游戏窗口
width, height = 356, 358
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption('刮刮乐游戏')
# 定义颜色
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
# 确保图片文件存在
if not os.path.isfile('bottom_image.png') or not os.path.isfile('top_image.png'):
raise Exception("图片文件未找到，请确保bottom_image.png和top_image.png文件在同一目录下。")
# 加载图片
bottom_image = pygame.image.load('bottom_image.png').convert()
top_image = pygame.image.load('top_image.png').convert_alpha()
# 调整图片大小以适应窗口
bottom_image = pygame.transform.scale(bottom_image, (width, height))
top_image = pygame.transform.scale(top_image, (width, height))
# 创建一个与顶层图片相同大小的透明表面
scratch_surface = pygame.Surface((width, height), pygame.SRCALPHA)
# 将顶层图片绘制到透明表面上
scratch_surface.blit(top_image, (0, 0))
# 游戏主循环
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
# 获取鼠标位置和状态
mouse_pos = pygame.mouse.get_pos()
mouse_pressed = pygame.mouse.get_pressed()
# 如果按下鼠标左键，则在透明表面上绘制透明圆形，模拟刮开效果
if mouse_pressed[0]: # 检测鼠标左键是否按下
pygame.draw.circle(scratch_surface, (0, 0, 0, 0), mouse_pos, 20)
# 绘制背景图片
screen.blit(bottom_image, (0, 0))
# 绘制刮开的透明表面
screen.blit(scratch_surface, (0, 0))
# 更新屏幕
pygame.display.flip()
# 退出游戏
pygame.quit()
运行效果：
二、多对图片的刮刮乐游戏
使用多对图片，准备了好了多对图片，如bottom1.png和top1.png 、 bottom2.png和top2.png 、 bottom2.png和top3.png，并将它们放到了img文件夹中。用户可以选择图对游戏，游戏过程中可按下ESC 键返回到菜单页开始重玩。
项目的目录（project_directory）结构如下：
源码如下：
import pygame
import os
import sys
# 初始化pygame
pygame.init()
# 设置游戏窗口
width, height = 356, 358
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption('刮刮乐游戏（可选择图片对）')
# 定义颜色
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
# 图片对列表
image_pairs = [
("img/bottom1.png", "img/top1.png"),
("img/bottom2.png", "img/top2.png"),
("img/bottom3.png", "img/top3.png")
]
# 加载图片
def load_images(pair_index):
bottom_image_path, top_image_path = image_pairs[pair_index]
bottom_image = pygame.image.load(bottom_image_path).convert()
top_image = pygame.image.load(top_image_path).convert_alpha()
bottom_image = pygame.transform.scale(bottom_image, (width, height))
top_image = pygame.transform.scale(top_image, (width, height))
return bottom_image, top_image
# 游戏主函数
def run_game(bottom_image, top_image):
scratch_surface = pygame.Surface((width, height), pygame.SRCALPHA)
scratch_surface.blit(top_image, (0, 0))
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
# 检测键盘事件以返回菜单
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_ESCAPE: # 按下ESC键
return # 返回到菜单，而不是退出游戏
mouse_pos = pygame.mouse.get_pos()
mouse_pressed = pygame.mouse.get_pressed()
if mouse_pressed[0]:
pygame.draw.circle(scratch_surface, (0, 0, 0, 0), mouse_pos, 20)
screen.blit(bottom_image, (0, 0))
screen.blit(scratch_surface, (0, 0))
pygame.display.flip()
# 菜单函数
def menu():
font = pygame.font.Font(None, 26)
menu_running = True
text_surfaces = []
text_rects = []
for i, pair in enumerate(image_pairs):
text = font.render(f"[ Image {i+1} ]", True, RED)
text_rect = text.get_rect(topleft=(10, 40 + i * 30))
text_surfaces.append(text)
text_rects.append(text_rect)
while menu_running:
screen.fill(WHITE)
text = font.render(f"Press Esc to return to the menu:", True, BLACK)
text_rect = text.get_rect(topleft=(10, 5))
screen.blit(text, text_rect)
for i, text in enumerate(text_surfaces):
screen.blit(text, text_rects[i])
pygame.display.flip()
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1: # Left click
for i, rect in enumerate(text_rects):
if rect.collidepoint(event.pos):
bottom_image, top_image = load_images(i)
run_game(bottom_image, top_image)
# 在这里不需要设置menu_running = False，因为我们希望在游戏结束后自动返回菜单
# 运行菜单
menu()
运行效果如下图所示：
用户可以单击菜单项选择图对游戏，游戏过程中可按下ESC 键返回到菜单页开始重玩。
