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。
