❥ 由于大三期末N个大课设轮番轰炸，停下了手里的好多事。
故时隔一月余久，我又去继续催化RPG小游戏Demo了。
❥ 此次短暂优化之后，基本的战斗系统、对话系统和背包系统已具雏形，
画面渲染也较为惹眼舒适了。
❥ 不知不觉，实习已近一月，在mentor的指导和同事的帮助下，成功接手并完成了一些开发业务单，明天开始为期两周左右的GameJam了，暂且搁置这一Demo探索。
❥ 等新鲜的-科技风-元素塔防出炉之后，再来和大家分享可以试玩的作品。
❥ 先有蛋还是先有鸡？反正先发B站才方便插视频URL hh~
⭐️部分场景展示：
⭐️项目的架构大致如下：
在此次的 Demo 制作中，借用了 Unity Asset Store 的一些免费资源，效果还是不错的
比如下面这个 Free SkyBox，可以呈现一个基础的3D天空场景
其实还是比较 beautiful 的对不对？ 这样的对目前来说其实也够用了
将 Materials 中的 Skybox 拖进 Hierarchy 中即可产生效果，主要是Unity的版本要 > 2019.4.0
在初步制作的时候，我们需要在基础之上对一些 Bug 进行纠错 (主要是效果展现上的差距和程序上的不完善)，最终不断丰富我们的表现效果。
要考虑的东西有很多：
⭐️比如如何设计角色移动和攻击方式 (在 Unity 客户端中，可以像我一样利用鼠标响应，点击即立刻前往，点击并拖拽光标能朝着光标拖拽的方向即时丝滑移动。当停止移动并在攻击范围之内，即可点击敌人进行攻击。移动Move() 与 攻击Combat() 的细节逻辑处理也是一个重要的东西，是利用了混合树结合代码逻辑解决的)；
⭐️比如死亡的对象要进行销毁，使它不再具有物理意义，也要注意不要让死亡的NPC跟随我们的角色移动，避免造成一种混乱的现象。
⭐️比如一个有地势差异的比较大的场景混合各种小场景，如何比较好的处理角色能否移动，这个时候我们就要利用 Bake烘焙 辅助处理，通过控制 Navigation 中 Bake 的属性值来准确控制表现效果，如下图：
NavMesh 与 Bake 具体可以参考下面两篇文章：
Unity | 深入了解NavMeshAgent_米莱虾的博客-CSDN博客_navmeshagent 详解
Unity | Navmesh自动寻路运行报错分析与解决方案_米莱虾的博客-CSDN博客
⭐️比如我们如何将视角绑定在角色身上或者别的想要被绑定的 target 上，这就要用到跟随相机，在 Camera 下挂载 Follow Camera，将 Follow Camera 调整到距离 target 合适的位置上并且与我们的目标绑定(挂载)，从而达到一个视角跟随主人公移动的效果，但其实没几行代码...
