（（Unity C＃）NPC不在草地和其他地形上移动

Question

我创建了一个跟随主要玩家的NPC。当玩家在NPC的某个范围内时，NPC应该根据玩家与NPC之间的距离进行行走，奔跑和攻击。 NPC附带了一个Animator，盒子对撞机，Nav Mesh Agent，Enemy Animator和Enemy Controller脚本。设置为follows，

我的问题是，如果地形上有某种草皮或蕨类植物，那么NPC不会追逐玩家。

NPC被设置为使用Nav Mesh Agent运行所有类型的地形，此外bake settings类似于图像中的。可以看到该问题的视频here。

敌方控制者的代码（尽管我怀疑这是问题）如下：

如果有人可以帮助解决这个问题，我将不胜感激！

编辑：我忘了添加草设置，这些如下。如您所见，没有对撞机。

我正在挖掘更多东西，显然唯一的步行区域如下（不是整个地图），如何调整此区域？
