Cardboard如何使用凝视触发移动

最后效果如下：

---

准备好两个脚本：
1. eyeselect4.cs
2. SmoothFollow.cs (注意这个脚本中最后一行中的约束代码要注释掉）

---

---

紧接着就是导入character包

重要一点的是删掉预设体中的Head层级，然后将CardboardHead组件添加到MainCamera上

---

---

Cardboard相机位置在高度上方向上的值是保持不变的

---

角色控制器的位置决定Cardboard的位置
CardBoard的旋转决定角色控制器的旋转
Cardboard相机的凝视触发角色控制器的移动

---

角色碰撞体（即player）的位置的竖直方向的值要靠eyeselect这个脚本中如下截图中代码来控制
