### Python垃圾分类小游戏代码示例与教程 以下是基于Pygame库开发的垃圾分类小游戏的完整代码示例。该游戏允许玩家控制角色捡起垃圾并将其分类到正确的垃圾桶中。如果分类正确，游戏成功；否则，游戏失败。 ```python import pygame as py import sys from pygame.locals import * # 初始化Pygame py.init() # 设置屏幕尺寸 screen = py.display.set_mode((1000, 650)) py.display.set_caption("Python垃圾分类小游戏") # 加载背景图片 background = py.image.load('Files\\background.jpg') background = py.transform.smoothscale(background, (1000, 650)) # 定义垃圾桶图片和位置 trash_bins = { '可回收物': py.image.load('Files\\recyclable_bin.png'), '厨余垃圾': py.image.load('Files\\kitchen_bin.png'), '有害垃圾': py.image.load('Files\\hazardous_bin.png'), '其他垃圾': py.image.load('Files\\other_bin.png') } bin_positions = [(100, 500), (350, 500), (600, 500), (850, 500)] # 加载垃圾图片 trash_images = { '塑料瓶': py.image.load('Files\\plastic_bottle.png'), '果皮': py.image.load('Files\\fruit_peel.png'), '电池': py.image.load('Files\\battery.png'), '纸巾': py.image.load('Files\\tissue_paper.png') } # 垃圾分类规则 classification_rules = { '塑料瓶': '可回收物', '果皮': '厨余垃圾', '电池': '有害垃圾', '纸巾': '其他垃圾' } # 角色选择函数 def choose_role(): background = py.image.load('Files\\choose_player\\background.jpg') background = py.transform.smoothscale(background, (1000, 650)) screen.blit(background, (0, 0)) man = py.image.load('Files\\choose_player\\man.png') man = py.transform.smoothscale(man, (123, 325)) man_button = screen.blit(man, (200, 200)) woman = py.image.load('Files\\choose_player\\woman.png') woman = py.transform.smoothscale(woman, (113, 325)) woman_button = screen.blit(woman, (687, 200)) py.display.flip() while True: for event in py.event.get(): if event.type == QUIT: sys.exit() if event.type == MOUSEBUTTONDOWN: pos = py.mouse.get_pos() if man_button.collidepoint(pos): return 'man' if woman_button.collidepoint(pos): return 'woman' # 游戏主循环 def main_game(): role = choose_role() current_trash = None running = True while running: screen.blit(background, (0, 0)) for name, img in trash_bins.items(): screen.blit(img, bin_positions[list(trash_bins.keys()).index(name)]) # 显示当前垃圾 if current_trash: mouse_x, mouse_y = py.mouse.get_pos() screen.blit(trash_images[current_trash], (mouse_x, mouse_y)) py.display.flip() for event in py.event.get(): if event.type == QUIT: running = False if event.type == MOUSEBUTTONDOWN: if not current_trash: # 随机选择一个垃圾 current_trash = list(trash_images.keys())[py.time.get_ticks() % len(trash_images)] if event.type == MOUSEBUTTONUP: if current_trash: mouse_x, mouse_y = py.mouse.get_pos() for i, pos in enumerate(bin_positions): bin_name = list(trash_bins.keys())[i] if pos[0] < mouse_x < pos[0] + 100 and pos[1] < mouse_y < pos[1] + 150: if classification_rules[current_trash] == bin_name: print(f"正确投放：{current_trash} -> {bin_name}") else: print(f"错误投放：{current_trash} -> {bin_name}") current_trash = None py.quit() if __name__ == "__main__": main_game() ``` #### 代码说明 1. **初始化与设置** 使用`pygame`初始化屏幕、加载背景图片和垃圾桶图片，并定义垃圾桶的位置[^1]。 2. **角色选择** 提供两个角色选项（男性和女性），玩家可以通过点击选择角色[^4]。 3. **垃圾生成与分类** 游戏随机生成垃圾，玩家需要将垃圾拖动到正确的垃圾桶中。如果分类正确，程序会输出“正确投放”；否则，输出“错误投放”[^3]。 4. **交互逻辑** 玩家通过鼠标点击选择垃圾，并拖动至垃圾桶进行分类。释放鼠标时，程序判断垃圾是否被投放到正确的垃圾桶中。 --- ###
