Pygame小游戏——自制版混乱大枪战

• 难度：中等-

• 应用技术：利用python 基于pygame第三方库制作的小游戏

• 开发原因：有天心血来潮想玩玩小时候玩的一款4399小游戏，但是又暂时想不起名字，于是便决定自己做一个自（山)制(寨)版
• （虽然做好后又想起了这款游戏叫做《混乱大枪战》…( ＿ ＿)ノ｜ 而且人物样子还是用的百战天虫的???(っ °Д °;)っ

• 主要收获：早期学习python过程中的一个练手项目，第一次尝试大量运用类，继承等OOP特性进行开发，并且逐渐熟悉了pygame库的使用，在游戏中加入了图片，音乐，以及最基础的物理系统（速度，加速度，碰撞，后坐力等）

• 不足：
  • 由于pygame第三方库的限制，许多想加入的功能只好放弃，比如原本考虑增加的射击、击中音效由于pygame只有应用于BGM的单音轨，只好放弃。
  • 由于pygame性能限制，导致插入背景图片会非常卡顿，所以只好再次沿用简陋的“纯黑”背景（当然也可能是我自己太弱不知道如何优化(；′⌒`)
  • 鉴于第一次大量使用类，导致写的非常混乱，各种继承乱七八糟，而且也没有很好的体现出类的可复用性，反而使代码异常繁杂，原本打算加入的多武器、技能等系统的加入或许会让类显得更加高效，但是由于种种原因（懒）而一直搁置，不知道以后会不会想起来慢慢更新吧，以后也应该好好多加强类的使用呜呜呜
  • 原本写的移动、碰撞系统简直糟糕的一塌糊涂，但是由于别人的提醒想到使用现实物理中的速度、加速度等概念一下子变得流畅、明朗了好多，看来自己以后也应当思维更加开阔才行欸

关于游戏

• 原本打算开发双人对战模式以及单人闯关模式，但是由于时间因素，以及对如何写AI的不熟练（其实还是懒）于是只写出来简陋的双人模式…
• 游戏操作：
  • player1: wasd控制方向，g为攻击键，提起大剑发起冲锋，有2s的冷却，在近距离冲撞到敌人会将敌人击飞
  • player2: ←↑↓→对应方向键，l为攻击键，使用手枪发出子弹，子弹只能在屏幕中存在3颗，手枪有一点后坐力，击中敌人会将其持续击飞
  • w键和↑键为喷气背包跳跃（虽然没有喷气效果o(￣▽￣)o）持续按住可以飞高，可在空中二连跳，但是要小心上方尖刺哦
  • 死亡判定：连续超出左右屏幕2s会造成死亡（在屏幕上会有提示）碰触到上下方的尖刺也同样会造成死亡
