最后我们在寻路后画线 1Vector3[] _path = Nav.path.corners;//储存路径2_lineRenderer.SetVertexCount(_path.Length);//设置线段数3for(inti =0; i < _path.Length; i++)4{5_lineRenderer.SetPosition(i, _path[i]);//设置线段顶点坐标6} 就这么简单,看看代码,看不懂先去看我上文提到的手册 由于...

寻路的功能使用A*算法即可,但下面要和大家介绍的不仅仅只是寻路,还要根据导航显示路径,下面就给大家介绍下使用NavMeshAgent寻路导航组件实现导航显示路径的方法。 效果如下: using UnityEngine; using UnityEngine.AI; // Use physics raycast hit from mouse click to set agent destination ...

Unity NavMeshAgent 方法/步骤 1 打开Unity，设置简单布局寻路场景，并设置为静态，具体如下图 2 在菜单“Window”-“Navigtion”的面板上“Bake”场景，具体如下图 3 在场景新建一个空物体，并且命名为“LineRender”，并添加组件“LineRenderer”，并添加材质和设置合适宽度，具体如下图 4 在场景中添加“Capsule...
