Unity3D AI导航 Area用法

## Area用法 ##

物体如果选择了区域，那么导航的路径只会选择区域内的路径。

越下层的区域，导航路径会优先选择。

## 实验步骤： ##

1.  新建五个地板对象，做成三座桥

2.  新建导航区域

3.  设置静态对象，给三座桥设置对应的区域

4.  创建3个颜色的贴图，这样方便我们理解区域的效果

5.  创建3个对象，并分别给3个对象3个不同的导航区域、不同的题图颜色

6.  在桥对面放置一个“cube”对象，作为桥对面3个对象的终点

7.  给三个对象添加同一脚本  
    ![在这里插入图片描述][20190829205352750.png]

## 脚本代码 ##

1.  通过名称发现物体对象：`cube = GameObject.Find("Cube").transform;`
2.  设置导航终点：`GetComponet<NavMeshAgent>().SetDestination(cube.position);`
