python实现有血条，有回血、障碍物、有计时的2d平面跑酷小游戏源码

以下是一个简单的Python实现有血条、有回血、有障碍物和有计时的2D平面跑酷小游戏的源码，供您参考：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 创建游戏窗口
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("2D平面跑酷小游戏")

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
green = (0, 255, 0)

# 定义游戏时钟和字体
clock = pygame.time.Clock()
font = pygame.font.SysFont(None, 25)

# 定义玩家类
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.Surface((50, 50))
        self.image.fill(green)
        self.rect = self.image.get_rect()
        self.rect.x = 50
        self.rect.y = screen_height - 100
        self.health = 100
        
    def update(self):
        # 玩家移动
        keys = pygame.key.get_pressed()
        if keys[pygame.K_LEFT]:
            self.rect.x -= 5
        elif keys[pygame.K_RIGHT]:
            self.rect.x += 5
        if keys[pygame.K_SPACE]:
            self.rect.y -= 5
        self.rect.y += 5
        
        # 碰撞检测
        if pygame.sprite.spritecollide(self, obstacles_group, False):
            self.health -= 10
        if self.health <= 0:
            game_over()
            
        # 回血
        if self.health < 100:
            self.health += 0.1

# 定义障碍物类
class Obstacle(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.Surface((50, 50))
        self.image.fill(red)
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(100, screen_width - 100)
        self.rect.y = -50
        
    def update(self):
        self.rect.y += 5
        if self.rect.y > screen_height:
            self.rect.x = random.randint(100, screen_width - 100)
            self.rect.y = -50

# 定义计时器函数
def timer(seconds):
    time_text = font.render("Time: " + str(seconds), True, black)
    screen.blit(time_text, (10, 10))

# 定义血条函数
def health_bar(player_health):
    pygame.draw.rect(screen, red, (10, 40, 100, 20))
    pygame.draw.rect(screen, green, (10, 40, player_health, 20))

# 定义游戏结束函数
def game_over():
    game_over_text = font.render("Game Over!", True, red)
    screen.blit(game_over_text, (screen_width/2 - 50, screen_height/2))
    pygame.display.update()
    pygame.time.delay(3000)
    pygame.quit()
    quit()

# 创建玩家和障碍物群组
player_group = pygame.sprite.Group()
player = Player()
player_group.add(player)

obstacles_group = pygame.sprite.Group()
for i in range(5):
    obstacle = Obstacle()
    obstacles_group.add(obstacle)

# 游戏循环
game_running = True
start_ticks = pygame.time.get_ticks()
while game_running:
    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_running = False
    
    # 计时器
    seconds = (pygame.time.get_ticks() - start_ticks) // 1000
    timer(seconds)
    
    # 绘制血条
    health_bar(player.health)
    
    # 更新玩家和障碍物
    player_group.update()
    player_group.draw(screen)
    
    obstacles_group.update()
    obstacles_group.draw(screen)
    
    # 刷新游戏窗口
    pygame.display.update()
    
    # 控制游戏帧率
    clock.tick(60)

# 退出 Pygame
pygame.quit()
