這篇文章主要介紹了如何基于python和pygame庫實(shí)現(xiàn)刮刮樂游戲,文中通過代碼示例和圖文給大家講解的非常詳細(xì),對(duì)大家的學(xué)習(xí)或工作有一定的幫助,需要的朋友可以參考下

用python和pygame庫實(shí)現(xiàn)刮刮樂游戲

首先，確保你已經(jīng)安裝了pygame庫。如果沒有安裝，可以通過以下命令安裝：

pip install pygame

示例有兩個(gè)。

一、簡(jiǎn)單刮刮樂游戲

準(zhǔn)備兩張圖片，一張作為背景bottom_image.png，一張作為刮開的圖片top_image.png：

請(qǐng)將bottom_image.png和top_image.png圖片文件與游戲代碼文件（.py文件）放在在同一目錄下。

以下是簡(jiǎn)單刮刮樂游戲的代碼：

import pygame
import os
 
# 初始化pygame
pygame.init()
 
# 設(shè)置游戲窗口
width, height = 356, 358
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption('刮刮樂游戲')
 
# 定義顏色
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
 
# 確保圖片文件存在
if not os.path.isfile('bottom_image.png') or not os.path.isfile('top_image.png'):
    raise Exception("圖片文件未找到，請(qǐng)確保bottom_image.png和top_image.png文件在同一目錄下。")
 
# 加載圖片
bottom_image = pygame.image.load('bottom_image.png').convert()
top_image = pygame.image.load('top_image.png').convert_alpha()
 
# 調(diào)整圖片大小以適應(yīng)窗口
bottom_image = pygame.transform.scale(bottom_image, (width, height))
top_image = pygame.transform.scale(top_image, (width, height))
 
# 創(chuàng)建一個(gè)與頂層圖片相同大小的透明表面
scratch_surface = pygame.Surface((width, height), pygame.SRCALPHA)
 
# 將頂層圖片繪制到透明表面上
scratch_surface.blit(top_image, (0, 0))
 
# 游戲主循環(huán)
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
 
    # 獲取鼠標(biāo)位置和狀態(tài)
    mouse_pos = pygame.mouse.get_pos()
    mouse_pressed = pygame.mouse.get_pressed()
 
    # 如果按下鼠標(biāo)左鍵，則在透明表面上繪制透明圓形，模擬刮開效果
    if mouse_pressed[0]:  # 檢測(cè)鼠標(biāo)左鍵是否按下
        pygame.draw.circle(scratch_surface, (0, 0, 0, 0), mouse_pos, 20)
 
    # 繪制背景圖片
    screen.blit(bottom_image, (0, 0))
 
    # 繪制刮開的透明表面
    screen.blit(scratch_surface, (0, 0))
 
    # 更新屏幕
    pygame.display.flip()
 
# 退出游戲
pygame.quit()

運(yùn)行效果：

二、多對(duì)圖片的刮刮樂游戲

使用多對(duì)圖片，準(zhǔn)備了好了多對(duì)圖片，如bottom1.png和top1.png 、 bottom2.png和top2.png 、 bottom2.png和top3.png，并將它們放到了img文件夾中。用戶可以選擇圖對(duì)游戲，游戲過程中可按下ESC 鍵返回到菜單頁開始重玩。

項(xiàng)目的目錄（project_directory）結(jié)構(gòu)如下：

源碼如下：

import pygame
import os
import sys
 
# 初始化pygame
pygame.init()
 
# 設(shè)置游戲窗口
width, height = 356, 358
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption('刮刮樂游戲（可選擇圖片對(duì)）')
 
# 定義顏色
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
 
# 圖片對(duì)列表
image_pairs = [
    ("img/bottom1.png", "img/top1.png"),
    ("img/bottom2.png", "img/top2.png"),
    ("img/bottom3.png", "img/top3.png")
]
 
# 加載圖片
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
 
# 游戲主函數(shù)
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
            # 檢測(cè)鍵盤事件以返回菜單
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_ESCAPE:  # 按下ESC鍵
                    return  # 返回到菜單，而不是退出游戲
        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()
 
# 菜單函數(shù)
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)
                        # 在這里不需要設(shè)置menu_running = False，因?yàn)槲覀兿Ｍ谟螒蚪Y(jié)束后自動(dòng)返回菜單
 
# 運(yùn)行菜單
menu()

運(yùn)行效果如下圖所示：
