pygame实现贪吃蛇小游戏
本文实例为大家分享了pygame实现贪吃蛇小游戏的具体代码，供大家参考，具体内容如下
由于这段时间实在是太聊了，没什么事做，游戏也玩腻了，所以玩起来pygame。pygame是真的容易上手，但用来做游戏也有很大的局限性，做一些小游戏还是没什么问题的。
首先，制作游戏最大的问题我认为是确定要制作的游戏的玩法，具体的细节都确定清楚之后再去实现还是很容易的。所以开发游戏最大的问题可能是需要一个好的创意，没有好的创意都没法开始。贪吃蛇相信没有人没玩过了，玩法也很简单，没吃一个方块可以使蛇的身体变长，头部碰到墙壁或者头部碰到自己身体就game over了。然后也需要一个计分板记录分数。由于只是一个简单的小游戏，不用一个具体的步骤了，就自己码代码的时候不断完善代码还是很容易完成的。
初步的版本，实现了蛇的移动和吃方块身体变长，但还没有检测导致game over 的时间。自己想到了不少事情，如可以记录游戏分数并保存到本地文件，记录最高分，但毕竟只是个小游戏，只要保证游戏的完整性就算过关了，再怎么追求完美也不过是用pygame开发的，其价值始终只在于自娱自乐。之后将这个版本完善一下就算完成了。

python 使用pygame工具包实现贪吃蛇游戏(多彩版)
今天我们用python和python的工具包pygame来编写一个贪吃蛇的小游戏 贪吃蛇游戏功能介绍 贪吃蛇的游戏规则如下: 通过上下左右键或者WASD键来移动蛇来,让它吃到食物,每吃到食物,蛇的长度变长,并获得分数.若蛇碰到游戏边际 或者自身,则蛇死亡,游戏结束. 游戏设计思路 根据游戏规则,我们需要: 1.初始化游戏环境. 2.初始化蛇.食物 3.监听键盘动作 4.蛇的运动,吃食物,是否死亡 5.该局游戏结束,是否还有再玩. 其中的难点在于如何在屏幕上展示蛇的运动,其实我们肉眼所见的蛇的运动
