如何用Python写一个Google:Dino Game小恐龙快跑

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置游戏窗口大小
SCREEN_WIDTH = 600
SCREEN_HEIGHT = 200

# 设置颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 创建游戏窗口
screen = pygame.display.set_mode([SCREEN_WIDTH, SCREEN_HEIGHT])

# 设置游戏标题
pygame.display.set_caption('Google Dino')

# 加载跳跃音效
jump_sound = pygame.mixer.Sound('jump.wav')

# 加载障碍物图像
cactus_img = pygame.image.load('cactus.png')
bird_img = pygame.image.load('bird.png')

# 定义 Dino 类
class Dino(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.image.load('dino.png')
        self.rect = self.image.get_rect()
        self.rect.x = 50
        self.rect.y = SCREEN_HEIGHT - 70
        self.jump_speed = 10
        self.gravity = 1

    def jump(self):
        self.rect.y -= self.jump_speed

    def update(self):
        self.rect.y += self.gravity
        if self.rect.y >= SCREEN_HEIGHT - 70:
            self.rect.y = SCREEN_HEIGHT - 70

# 定义障碍物类
class Obstacle(pygame.sprite.Sprite):
    def __init__(self, img):
        super().__init__()
        self.image = img
        self.rect = self.image.get_rect()
        self.rect.x = SCREEN_WIDTH
        self.rect.y = SCREEN_HEIGHT - 90

    def update(self):
        self.rect.x -= 5

# 创建 Dino 对象
dino = Dino()

# 创建障碍物组
obstacle_group = pygame.sprite.Group()

# 设置游戏帧率
clock = pygame.time.Clock()

# 初始化分数和难度
score = 0
difficulty = 1

# 游戏主循环
running = True
while running:

    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE and dino.rect.y == SCREEN_HEIGHT - 70:
                dino.jump()
                jump_sound.play()

    # 更新 Dino 对象
    dino.update()

    # 创建障碍物
    if random.randint(1, 100) <= difficulty:
        obstacle_type = random.randint(1, 2)
        if obstacle_type == 1:
            obstacle = Obstacle(cactus_img)
        else:
            obstacle = Obstacle(bird_img)
        obstacle_group.add(obstacle)

    # 更新障碍物
    for obstacle in obstacle_group:
        obstacle.update()
        if obstacle.rect.x <= -50:
            obstacle_group.remove(obstacle)
            score += 1
            if score % 10 == 0:
                difficulty += 1

    # 检测碰撞
    if pygame.sprite.spritecollide(dino, obstacle_group, False):
        running = False

    # 绘制游戏画面
    screen.fill(WHITE)
    pygame.draw.rect(screen, BLACK, [0, SCREEN_HEIGHT - 70, SCREEN_WIDTH, 2])
    screen.blit(dino.image, dino.rect)
    obstacle_group.draw(screen)

    # 绘制分数
    font = pygame.font.Font(None, 36)
    text = font.render('Score: ' + str(score), True, RED)
    screen.blit(text, [SCREEN_WIDTH - 120, 10])

    # 更新游戏画面
    pygame.display.update()

    # 控制游戏帧率
    clock.tick(30)

# 结束 Pygame
pygame.quit()

请注意，在运行此游戏之前，您需要准备一些图像和音频文件，并将其命名为 dino.png、cactus.png、bird.png 和 jump.wav。
