新人一枚以下是一个使用Python 3.7和Pygame库编写的贪食蛇游戏，包含重来和退出按钮：
python
import pygame
import random初始化Pygame
pygame.init()
定义窗口大小和标题
screen_width = 400
screen_height = 400
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("贪食蛇")定义颜色
white = (255, 255, 255)
red = (255, 0, 0)
green = (0, 255, 0)
blue = (0, 0, 255)定义蛇、食物和墙的大小和速度
snake_size = 20
snake_speed = 10
food_size = 20
food_speed = random.randint(1, 5)
wall_size = screen_width // 100
wall_speed = 1定义蛇、食物和墙的初始位置和方向
snake_pos = [[100, 100]]
snake_dir = right = 0
food_pos = [random.randint(wall_size, screen_width - wall_size), random.randint(wall_size, screen_height - wall_size)]
food_spawn = True
walls = [[screen_width // 2 - wall_size // 2, screen_height // 2 - wall_size // 2], [screen_width // 2 - wall_size // 2, screen_height // 2 + wall_size // 2], [screen_width // 2 + wall_size // 2, screen_height // 2 + wall_size // 2], [screen_width // 2 + wall_size // 2, screen_height // 2 - wall_size // 2]]
current_wall = random.choice(walls)
next_wall = random.choice(walls)
walls.remove(current_wall)
clock = pygame.time.Clock()
font = pygame.font.SysFont("arial", 30)
message = font.render("Game Over", True, red)
message_rect = message.get_rect()
message_rect.centerx = screen_width // 2
message_rect.centery = screen_height // 2 - message_rect.height // 2 - 50
game_over = False
score = len(snake_pos) - 1
level = 1
levels = [15, 10, 7.5, 6, 4.5, 3.5]
level_progress = level - levels[0] + 1
level_text = font.render("Level: " + str(level), True, green)
level_rect = level_text.get_rect()

要使用Python编写一个简单的贪食蛇游戏并添加重来和退出按钮，您可以使用pygame库，这是一个非常强大的库，可以用来创建2D游戏和交互式图形用户界面。
以下是一个基本的贪食蛇游戏的代码示例：import pygame import random # 初始化pygame pygame.init() # 设置屏幕大小 screen_width = 480 screen_height = 640 screen = pygame.display.set_mode((screen_width, screen_height)) # 定义颜色常量 WHITE = (255, 255, 255) BLACK = (0, 0, 0) GREEN = (0, 255, 0) RED = (255, 0, 0) # 蛇头初始位置 snake_x = screen_width / 2 snake_y = screen_height / 2 # 蛇的身体部分 body_parts = [[snake_x, snake_y]] # 移动速度 speed = [0, 0] # 食物的位置 food_x = random.randint(10, screen_width - 10) food_y = random.randint(10, screen_height - 10) # 游戏循环 while True: # 监听事件 for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() sys.exit() # 更新键盘输入 keys = pygame.key.get_pressed() if keys[pygame.K_UP]: speed[1] = -5 speed[0] = 0 elif keys[pygame.K_DOWN]: speed[1] = 5 speed[0] = 0 elif keys[pygame.K_LEFT]: speed[0] = -5 speed[1] = 0 elif keys[pygame.K_RIGHT]: speed[0] = 5 speed[1] = 0 # 更新蛇的位置 snake_x += speed[0] snake_y += speed[1] # 绘制背景色 screen.fill(BLACK) # 绘制食物 pygame.draw.rect(screen, GREEN, [food_x, food_y, 10, 10]) # 绘制蛇的身体 for x, y in body_parts[:-1]: pygame.draw.rect(screen, WHITE, [x, y, 10, 10]) # 绘制蛇头 pygame.draw.rect(screen, RED, [snake_x, snake_y, 10, 10]) # 添加食物到蛇的身体 if snake_x == food_x and snake_y == food_y: food_x = random.randint(10, screen_width - 10) food_y = random.randint(10, screen_height - 10) body_parts.append([snake_x, snake_y]) # 更新游戏状态 body_parts.pop(0) body_parts.append([snake_x, snake_y]) # 判断游戏是否结束 if len(body_parts) >= 5: print("Game Over") break # 更新屏幕 pygame.display.update()2023-11-03 21:58:10赞同 展开评论 打赏
