基于unity的2D横版游戏开发日志 小结
前言
说是基于unity的2D横版游戏，实际上只是一个初学unity与C#新人的练手Demo，目前还处于半成状态。美术资源方面全部出自unity免费资源，经过自己的小修，大致拼出了一个游戏。代码方面，仅仅初识C#语法，此前从未接触过面向对象编程的我，显然写出来的东西显然不堪入目，问题包括但不限于：1.未遵守命名规范。2.未领会面向对象编程的思想，代码复用随处可见。3.代码思路及其不清晰，动画状态转换判断一半靠动画机参数，一半靠代码里的if else（再三确认.jpg）。4.总体架构没想好，想到哪写哪，beAttackBox满足不了要求写个beAttackBoxOfEnemy，还不行就beAttackBoxOfBoss，看架势如果写完整个游戏，要写上千个脚本。5.维护性极差，脚本功能纵横交错，出了问题现在的我能解决，过一个月就只有上帝能解决了。
总而言之，这段小结仅出于记录自己黑历史的目的，冒着荣登知乎“你见过最烂的代码是怎样的”这一问题榜首的风险发布，不敢劳烦各位大佬斧正，只希望大伙就看个乐呵，尽量不要进行人身攻击，以下是展示部分。

游戏展示
由于还有有关游戏导出分辨率的问题尚未解决，展示仅在编译器中进行。
1.近战敌人演示
2.远程敌人演示
3.boss战（自己写的boss都能过不了？）
部分代码展示
boss1AI
//bossAI形式不同于小怪enemyAI，不具有普适性。
//boss1行动模式用自然语言描述如下：
//在场景中，boss一直处于战斗状态，以若干秒为一个周期，根据所设计的概率随机选择一个符合条件（与玩家的距离、自身血量所决定的阶段、技能冷却情况）的
//行动（发动某攻击，接近玩家，远离玩家），在完成行动后，进入后摇时间，后摇结束后进入下一周期，在受击动画完成后若干秒，立刻进入下一个周期。
//行动并不仅限于一个动画，可以考虑两个动画进行组合以实现连招。boss子物体包含若干个范围盒，按由外到内的顺序排列，每进入一个范围盒，可随机选择的动作增加。
//由外到内，增加的可选择动作为:
//1.接近玩家。
//2.远离玩家、发动技能跳斩attack5（仅在该范围盒）、发动技能突刺attack2（二阶段新增技能旋转攻击attack4，隐身突袭attack3）。
//3.普通攻击attack1、击退踢腿attack6(后接突刺或跳斩)。
//具体数值见boss1Const
/*其余说明：1.boss面向改变不属于行动，于等待阶段进行。
* 2.当血量低于50时，进入二阶段，立即进行三次隐身突袭attack3，并减少单个周期的时间以实现行动后摇减少，加速敌人攻击。
* 3.一定时间内受击超过一定次数时，boss会踢腿击退接突刺或跳斩的连招
