bat小游戏代码大全

以下是两个关于贪吃蛇游戏的Python代码示例：

1. 百行Python代码实现贪吃蛇游戏：

import pygame
import sys
import random

# 初始化游戏
pygame.init()

# 设置游戏窗口大小
window_width = 800
window_height = 600
window_size = (window_width, window_height)
window = pygame.display.set_mode(window_size)
pygame.display.set_caption("贪吃蛇游戏")

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

# 定义贪吃蛇的初始位置和大小
snake_size = 20
snake_x = window_width / 2
snake_y = window_height / 2

# 定义贪吃蛇的移动速度
snake_speed = 10
snake_x_change = 0
snake_y_change = 0

# 定义食物的初始位置和大小
food_size = 20
food_x = round(random.randrange(0, window_width - food_size) / 20) * 20
food_y = round(random.randrange(0, window_height - food_size) / 20) * 20

# 定义贪吃蛇的身体
snake_body = []
snake_length = 1

# 定义游戏结束的标志
game_over = False

# 游戏主循环
while not game_over:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                snake_x_change = -snake_size
                snake_y_change = 0
            elif event.key == pygame.K_RIGHT:
                snake_x_change = snake_size
                snake_y_change = 0
            elif event.key == pygame.K_UP:
                snake_y_change = -snake_size
                snake_x_change = 0
            elif event.key == pygame.K_DOWN:
                snake_y_change = snake_size
                snake_x_change = 0

    # 更新贪吃蛇的位置
    snake_x += snake_x_change
    snake_y += snake_y_change

    # 判断是否吃到食物
    if snake_x == food_x and snake_y == food_y:
        food_x = round(random.randrange(0, window_width - food_size) / 20) * 20
        food_y = round(random.randrange(0, window_height - food_size) / 20) * 20
        snake_length += 1

    # 绘制游戏窗口
    window.fill(black)
    pygame.draw.rect(window, green, [food_x, food_y, food_size, food_size])
    snake_head = []
    snake_head.append(snake_x)
    snake_head.append(snake_y)
    snake_body.append(snake_head)
    if len(snake_body) > snake_length:
        del snake_body[0]

    for segment in snake_body[:-1]:
        if segment == snake_head:
            game_over = True

    for segment in snake_body:
        pygame.draw.rect(window, white, [segment[0], segment[1], snake_size, snake_size])

    pygame.display.update()

    # 判断游戏是否结束
    if snake_x < 0 or snake_x >= window_width or snake_y < 0 or snake_y >= window_height:
        game_over = True

    pygame.time.Clock().tick(snake_speed)

# 退出游戏
pygame.quit()
sys.exit()

2. 使用set数据结构判断贪吃蛇是否咬到自身的代码：

def game_over(snake):
    broad_x, broad_y = snake.get_head()
    flag = 0
    old = len(snake.item)
    new = len(set(snake.item))
    if new < old:
        flag = 1
    if broad_x == 0 or broad_x == BOARDWIDTH - 1:
        flag = 1
    if broad_y == 0 or broad_y == BOARDHEIGHT - 1:
        flag = 1
    if flag:
        return True
    else:
        return False
