2600平台移植和改进版。

<>主要内容

* 创建游戏窗口
* 绘制贪吃蛇与食物
* 蛇吃食物
<>贪吃蛇的棋盘模型

<>导入模块
import pygame import random import copy

* 游戏初始化 pygame.init() clock = pygame.time.Clock() # 设置游戏时钟
pygame.display.set_caption("贪吃蛇-解答、源码、相关资料可私信我") # 初始化标题 screen =
pygame.display.set_mode((500, 500)) # 初始化窗口 窗体的大小为 500 500
* 初始化蛇的位置 蛇的长度10 10（蛇的 X Y 坐标） snake_list = [[10, 10]]

<>初始小蛇方向
move_up = False move_down = False move_left = False move_right = True
* 初始化食物的位置 x = random.randint(10, 490) y = random.randint(10, 490)
food_point = [x, y]
* 开启游戏循环 running = True while running: # 游戏时钟 刷新频率 clock.tick(20)
* 填充背景为白色 screen.fill([255, 255, 255])
* 绘制背景 for x in range(0, 501, 10): pygame.draw.line(screen, (195, 197, 199),
(x, 0), (x, 500), 1) pygame.draw.line(screen, (195, 197, 199), (0, x), (500,
x), 1) food_rect = pygame.draw.circle(screen, [255, 0, 0], food_point, 15, 0)

snake_rect = [] for pos in snake_list: # 1.7.1 绘制蛇的身子
snake_rect.append(pygame.draw.circle(screen, [255, 0, 0], pos, 5, 0))

* 获取蛇的长度，移动蛇的身子 pos = len(snake_list) - 1 while pos > 0: snake_list[pos] =
copy.deepcopy(snake_list[pos - 1]) pos -= 1
* 更改蛇头位置 if move_up: snake_list[pos][1] -= 10 if snake_list[pos][1] < 0:
snake_list[pos][1] = 500 if move_down: snake_list[pos][1] += 10 if
snake_list[pos][1] > 500: snake_list[pos][1] = 0 if move_left:
snake_list[pos][0] -= 10 if snake_list[pos][0] < 0: snake_list[pos][0] = 500 if
move_right: snake_list[pos][0] += 10 if snake_list[pos][0] > 500:
snake_list[pos][0] = 0
* 键盘控制移动职位 for event in pygame.event.get(): # print(event) # 判断按下的按键 if
event.type == pygame.KEYDOWN: # 上键 if event.key == pygame.K_UP: move_up = True
move_down = False move_left = False move_right = False # 下键 if event.key ==
pygame.K_DOWN: move_up = False move_down = True move_left = False move_right =
False # 左键 if event.key == pygame.K_LEFT: move_up = False move_down = False
move_left = True move_right = False # 右键 if event.key == pygame.K_RIGHT:
move_up = False move_down = False move_left = False move_right = True
* 获取蛇的长度，移动蛇的身子 pos = len(snake_list) - 1 while pos > 0: snake_list[pos] =
copy.deepcopy(snake_list[pos - 1]) pos -= 1

<>蛇吃食物

* 碰撞检测 如果蛇吃掉食物 if food_rect.collidepoint(pos): # 贪吃蛇吃掉食物
snake_list.append(food_point) # 重置食物位置 food_point = [random.randint(10, 490),
random.randint(10, 490)] food_rect = pygame.draw.circle(screen, [255, 0, 0],
food_point, 15, 0) break
* 如果蛇吃掉了自己 head_rect = snake_rect[0] count = len(snake_rect) while count >
1: if head_rect.colliderect(snake_rect[count - 1]): running = False count -= 1
pygame.display.update()

<>完成！
