unity3d：动态寻路NavMesh（NavMeshComponents不须要烘焙场景，实时烘焙）

静态烘焙：
动态障碍物，大小要和包围盒大小一致

动态烘焙：
官方最新的 https://github.com/luoyikun/NavMeshComponents
1.能够实现烘焙信息跟随预制体

2.动态烘焙：以玩家为中心，走哪烘哪
管理器上挂载

tracked为玩家

动态烘焙中的障碍物

要挂载在mesh上

[MenuItem("HomeTool/AddNavTag")]
    public static void AddNavTag()
    {
        GameObject obj = Selection.activeGameObject;
        foreach (var item in obj.transform.GetComponentsInChildren<Renderer>())
        {
            if (item.GetComponent<NavMeshSourceTag>() == null)
            {
                item.gameObject.AddComponent<NavMeshSourceTag>();
            }
        }
    }

显示寻路路径在scene视图中

void OnDrawGizmos()
    {
        var path = m_agent.path;
        // color depends on status
        Color c = Color.white;
        switch (path.status)
        {
            case UnityEngine.AI.NavMeshPathStatus.PathComplete: c = Color.white; break;
            case UnityEngine.AI.NavMeshPathStatus.PathInvalid: c = Color.red; break;
            case UnityEngine.AI.NavMeshPathStatus.PathPartial: c = Color.yellow; break;
        }
        // draw the path
        for (int i = 1; i < path.corners.Length; ++i)
            Debug.DrawLine(path.corners[i - 1], path.corners[i], c);
    }
