Unity NavMesh导航报错“SetDestination“ can only be called on an active agent that has been placed on a Na

在使用NavMeshAgent进行导航的时候，发现调用SetDestination一直报错，报错显示是：

"SetDestination" can only be called on an active agent that has been placed on a NavMesh.
UnityEngine.AI.NavMeshAgent:SetDestination(Vector3)

但是查看地图，发现Bake过了，Agent也在地图上啊，照理说会自动关联到NavMesh地图上的。

后来发现是因为NavMeshAgent不能直接设置position因为那样他不知道他现在在哪里。

如果您创建一个 NavMeshAgent 并通过 transform.position=... 设置它的位置，然后尝试 SetDestination，它会失败，因为 NavMeshAgent 没有识别位置变化并且不知道它已经在 NavMesh 上。在调用 SetDestination 之前，使用 NavMeshAgent.Warp 而不是 transform.position 来初始化位置。

错误代码：

character.transform.position = pos;

正确代码：

character.Warp(pos);
