Unity 小游戏：3D射箭，供大家参考，具体内容如下
前两周因为实训太忙，再加上自己对老师所讲的设计模式并不是很理解，所以就没有写博客。这次博客是记录3D射箭游戏的实现过程。
1. 准备资源
我是在网上找的弓与箭的资源，至于靶子，创建五个不同大小的同心圆柱体，如图所示：
需要注意的是，五个圆柱体并不在同一个平面上，这样才能够看清每一环的颜色，并且在检测碰撞时不会出现各种问题。
另外，如果靶子放得离相机太近，就没有射箭的感觉了；离相机太远，好像又看不清靶子了，然后我试着把靶子Material的Shader改为 Sprites/Default ，这样靶子离相机远一点也能看得很清晰。
2. 布置场景
把弓箭作为Main Camera的子物体，这样我们可以在用鼠标控制镜头移动时，使弓箭一直指向屏幕中心，以达到第一人称控制器的效果。
在此项目中，没有选择使用GUI来做UI界面，而是创建了一个Canvas，在这里面添加了一个Image用来显示弓箭的准心，以及四个Text来显示得分、风向、风力、提示等。
3. 编辑脚本
游戏采用MVC架构，大部分功能是自己实现的，也有一小些函数是借鉴大神的。整体上感觉有很多缺陷，但是又不知道怎么修改才好，我也很无奈啊！°(°ˊДˋ°) °
下面是我的UML图：
