当我们在编写贪吃蛇游戏时,首先需要考虑游戏的基本元素,包括蛇的移动、食物的生成、游戏结束的判断等。接下来我会给你一个简单的贪吃蛇代码:
- import pygame
- import random
- pygame.init()
- # 设置屏幕大小
- screen_width = 600
- screen_height = 400
- # 设置颜色
- black = (0, 0, 0)
- white = (255, 255, 255)
- red = (255, 0, 0)
- # 初始化屏幕
- screen = pygame.display.set_mode((screen_width, screen_height))
- pygame.display.set_caption('贪吃蛇游戏')
- # 蛇的初始位置和长度
- snake_pos = [100, 50]
- snake_body = [[100, 50], [90, 50], [80, 50]]
- # 食物的初始位置
- food_pos = [random.randrange(1, screen_width//10)*10, random.randrange(1, screen_height//10)*10]
- food_spawn = True
- # 设置方向
- direction = 'RIGHT'
- change_to = direction
- # 设置速度
- snake_speed = 15
- clock = pygame.time.Clock()
- # 定义游戏结束函数
- def game_over():
- font_style = pygame.font.SysFont(None, 50)
- message = font_style.render('Game Over!', True, red)
- screen.blit(message, [screen_width/2-100, screen_height/2-50])
- pygame.display.flip()
- pygame.time.wait(2000)
- pygame.quit()
- # 游戏主循环
- while True:
- for event in pygame.event.get():
- if event.type == pygame.QUIT:
- pygame.quit()
- # 检测键盘输入
- elif event.type == pygame.KEYDOWN:
- if event.key == pygame.K_RIGHT:
- change_to = 'RIGHT'
- if event.key == pygame.K_LEFT:
- change_to = 'LEFT'
- if event.key == pygame.K_UP:
- change_to = 'UP'
- if event.key == pygame.K_DOWN:
- change_to = 'DOWN'
- # 碰撞检测
- if snake_pos[0] >= screen_width or snake_pos[0] < 0 or snake_pos[1] >= screen_height or snake_pos[1] < 0:
- game_over()
-
- for block in snake_body[1:]:
- if snake_pos[0] == block[0] and snake_pos[1] == block[1]:
- game_over()
- # 更新蛇的位置
- if change_to == 'RIGHT' and not direction == 'LEFT':
- direction = 'RIGHT'
- if change_to == 'LEFT' and not direction == 'RIGHT':
- direction = 'LEFT'
- if change_to == 'UP' and not direction == 'DOWN':
- direction = 'UP'
- if change_to == 'DOWN' and not direction == 'UP':
- direction = 'DOWN'
- if direction == 'RIGHT':
- snake_pos[0] += 10
- if direction == 'LEFT':
- snake_pos[0] -= 10
- if direction == 'UP':
- snake_pos[1] -= 10
- if direction == 'DOWN':
- snake_pos[1] += 10
- snake_body.insert(0, list(snake_pos))
- if snake_pos[0] == food_pos[0] and snake_pos[1] == food_pos[1]:
- food_spawn = False
- else:
- snake_body.pop()
- if not food_spawn:
- food_pos = [random.randrange(1, screen_width//10)*10, random.randrange(1, screen_height//10)*10]
- food_spawn = True
-
- screen.fill(black)
-
- for pos in snake_body:
- pygame.draw.rect(screen, white, pygame.Rect(pos[0], pos[1], 10, 10))
-
- pygame.draw.rect(screen, red, pygame.Rect(food_pos[0], food_pos[1], 10, 10))
- pygame.display.update()
-
- clock.tick(snake_speed)
