SteamVR 2.0 交互（二）
脚本分析
player.cs
Interable.cs
加上可以进行交互。创建高亮。
InterableHoverEvents.cs
交互后的Event
Throw.cs
加上可以被捡起。
下边文章都是代码，自行复制。后几篇，更新 传送Teleport.cs TelelportPoint等脚本。
疑问： 不知道Hand使用了什么方法对物体检测，应该也是碰撞检测，做了个测试 ，禁用BoxColider后 ，就拿不起来。
但是Hand.cs中没有找到OnTrrigerEnter碰撞函数。也许放到其他脚本中。
这里我对脚本进行了注释，后期完善
如果多的话 ，可以复制脚本去查看。
还有一个问题，启动查看实例 后，会发现 Player 为不销毁的，
最后找了半天，这个逻辑DontDestroyOnLoad 写在了这个脚本中。勾选即可
事件检测，其实不是事件 steamvr用的是SendMessage
这里是检测,给可以建起来的物品添加脚本，拾取 就可以看到输出。

Hand.cs：
vr手柄按键检测 ，拾取物品，需要 Throw.cs Interable.cs等脚本
在处理，拾取物品时遇到一些问题，
Steamvr案例给的是，扳机、侧键、鼠标左键。按下拾取物品，松开丢弃。
然后我更改为，扳机点击、鼠标点击拾取物品，空格、侧键丢弃物品。
，自行查看逻辑。 中文都注释好了。
