Python+Pygame开发太空大战/飞机大战完整游戏项目（附源代码）

阅读原文时间：2023年07月08日阅读：2

项目名称：太空大战

开发环境：Python3.6.4

第三方库：Pygame1.9.6

代码编辑器：Sublime Text

先来看一下游戏画面吧！游戏画面动态且丰富哦！

需求分析

利用Python开发一个太空大战，提供UI，Bgm，丰富的游戏图片素材，左上角拥有玩家的生命进度条且能够动态变化，右上角拥有玩家的生命条数
游戏精灵能够动态交互，打败敌人能够有动态的爆炸效果(用静态图片循环播放可实现)，且打败敌人能够随机的掉落火箭，增加生命进度甚至增加生命条数(有一个所获几率的控制)的游戏精灵，打败敌人能够获得分数
算法设计：能够根据玩家的生命进度及生命条数调整游戏难度和获得火箭，生命数等精灵的概率
设计动态地图，使游戏更加动态化以及游戏化

　　注意bgm及音效的路径，我的是相对路径，路径一定要对，否则程序无法读取图片及音乐哦！
