贪吃蛇小游戏，那个曾经陪伴着00后和90后度过无数欢笑时光的熟悉身影，仿佛是一把打开时光之门的钥匙。它不仅是游戏世界的经典之一，更是我们童年岁月中不可或缺的一部分，一个承载回忆的游乐场。
今天，我怀着对过去美好时光的怀念，决定带领大家一同重温这个经典之作。十分钟的时间，足够我们完成一个贪吃蛇小游戏的从零到一的制作过程，唤起那些沉淀在记忆深处的片段，重新演绎一场美好的回忆之旅。

坐标
游戏开发的过程就像是一场时光穿越，从屏幕宽度、高度到小方格大小的定义，每一行代码都是对童年时光的致敬。这个过程不仅是技术的挑战，更是对那段充满激情和无限可能的年华的致敬。
贪吃蛇的身影在初始化的瞬间重新出现，如同见到了一个久违的老友。我们为它赋予了起始的位置和长度，仿佛重新揭开了小时候那个属于自己的游戏序幕。这个小小的蛇身，是我们成长路上最初的探险者，见证了我们一步步蜕变的过程。
SCREEN_WIDTH = 600 # 屏幕宽度
SCREEN_HEIGHT = 480 # 屏幕高度
SIZE = 20 # 小方格大小
LINE_WIDTH = 1 # 网格线宽度
SCOPE_X = (0, SCREEN_WIDTH // SIZE - 1) # 游戏区域的坐标范围
SCOPE_Y = (2, SCREEN_HEIGHT // SIZE - 1)
FOOD_STYLE_LIST = [(10, (255, 100, 100)), (20, (100, 255, 100)), (30, (100, 100, 255))]
LIGHT = (100, 100, 100)
DARK = (200, 200, 200) # 蛇的颜色
BLACK = (0, 0, 0) # 网格线颜色
RED = (200, 30, 30) # 红色，GAME OVER 的字体颜色
BGCOLOR = (40, 40, 60) # 背景色
def print_text(screen, font, x, y, text, fcolor=(255, 255, 255)):
imgText = font.render(text, True, fcolor)
screen.blit(imgText, (x, y))
def init_snake():
snake = deque()
snake.append((2, SCOPE_Y[0]))
snake.append((1, SCOPE_Y[0]))
snake.append((0, SCOPE_Y[0]))
return snake
def create_food(snake):
food_x = random.randint(SCOPE_X[0], SCOPE_X[1])
food_y = random.randint(SCOPE_Y[0], SCOPE_Y[1])
while (food_x, food_y) in snake:
food_x = random.randint(SCOPE_X[0], SCOPE_X[1])
food_y = random.randint(SCOPE_Y[0], SCOPE_Y[1])
return food_x, food_y
def get_food_style():
return FOOD_STYLE_LIST[random.randint(0, 2)]
接下来，食物的生成成为游戏中一个不可或缺的元素。通过随机生成食物的位置、不同食物的分值和颜色，我们为游戏注入了更多的趣味性和挑战性。这一步仿佛是在重新编织那些小时候追逐食物的记忆，让我们感受到小时候的单纯和快乐。
主游戏循环模块
游戏循环的设计，通过键盘输入监听实现蛇的移动和游戏的暂停，让我们仿佛回到了小时候手持小键盘的场景。这个过程不仅是对技术的实践，更是一次与自己童年亲密互动的体验。
