pygame 垃圾分类小游戏

以下是使用pygame实现垃圾分类小游戏的步骤：

1.导入pygame库和其他必要的库

import pygame
import random
import sys

2.初始化pygame

pygame.init()

3.设置游戏窗口大小和标题

screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("Garbage Classification Game")

4.定义游戏中需要用到的颜色

BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)

5.定义垃圾分类的类

class Garbage(pygame.sprite.Sprite):
    def __init__(self, image, kind):
        super().__init__()
        self.image = image
        self.rect = self.image.get_rect()
        self.kind = kind

6.加载垃圾图片

paper_img = pygame.image.load("paper.png").convert_alpha()
plastic_img = pygame.image.load("plastic.png").convert_alpha()
metal_img = pygame.image.load("metal.png").convert_alpha()
other_img = pygame.image.load("other.png").convert_alpha()

7.创建垃圾分类的组

garbage_group = pygame.sprite.Group()

8.生成随机垃圾并添加到垃圾分类组中

for i in range(10):
    kind = random.choice(["paper", "plastic", "metal", "other"])
    if kind == "paper":
        garbage = Garbage(paper_img, "paper")
    elif kind == "plastic":
        garbage = Garbage(plastic_img, "plastic")
    elif kind == "metal":
        garbage = Garbage(metal_img, "metal")
    else:
        garbage = Garbage(other_img, "other")
    garbage.rect.x = random.randint(0, 700)
    garbage.rect.y = random.randint(0, 500)
    garbage_group.add(garbage)

9.定义得分和时间

score = 0
time = 60

10.创建字体对象

font = pygame.font.Font(None, 36)

11.游戏主循环

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        elif event.type == pygame.MOUSEBUTTONDOWN:
            pos = pygame.mouse.get_pos()
            clicked_garbage = [garbage for garbage in garbage_group if garbage.rect.collidepoint(pos)]
            if clicked_garbage:
                if clicked_garbage[0].kind == "paper":
                    score += 10
                elif clicked_garbage[0].kind == "plastic":
                    score += 20
                elif clicked_garbage[0].kind == "metal":
                    score += 30
                else:
                    score -= 10
                garbage_group.remove(clicked_garbage[0])
    screen.fill(WHITE)
    garbage_group.draw(screen)
    score_text = font.render("Score: {}".format(score), True, BLACK)
    screen.blit(score_text, (10, 10))
    time_text = font.render("Time: {}".format(time), True, BLACK)
    screen.blit(time_text, (700, 10))
    pygame.display.flip()
    pygame.time.wait(1000)
    time -= 1
    if time == 0:
        break

12.游戏结束后显示得分

gameover_text = font.render("Game Over! Your score is {}".format(score), True, RED)
screen.blit(gameover_text, (250, 250))
pygame.display.flip()
pygame.time.wait(3000)
