今天遇到一个问题，就是怎样处理一些动态的障碍物。

NavMesh是能够躲避静态的障碍物。NavMeshObstacle的作用就是动态添加障碍。

可是有个问题，NavMeshObstacle是圆，连椭圆都不行，所以。仅仅好写一个附属脚本。用圆拼成矩形，就能够了。

using UnityEngine;using System.Collections;public class NavMeshObstacleHelper : MonoBehaviour {	//coordinate	public float X = 0f;	public float Y = 0f;	public float Z = 0f;	public float Length = 0f;	public float Width = 0f;	public float Height = 0f;	public float Diameter = 0f;	private int lengthCount = 0;	private float lengthStep = 0f;	private int widthCount = 0;	private float widthStep = 0f;	private GameObject obstacleArray = null;	private GameObject obstacle = null;	void Awake()	{		obstacleArray = new GameObject ();		obstacleArray.name = "NavMeshObstacleArray";		widthCount = (int)(Width / Diameter);			lengthCount = (int) (Length / Diameter);		if (lengthCount > 1)		{			lengthStep = (Length - Diameter * lengthCount) / (lengthCount - 1);		}				if (widthCount > 1)		{			widthStep = (Width - Diameter * widthCount) / (widthCount - 1);		}	}	// Use this for initialization	void Start () {		initObstacleArray ();	}	private void initObstacleArray()	{		Vector3 tempPos = new Vector3 (X, Y, Z);		for (int i = 0; i < lengthCount; i++)		{			for (int j = 0; j < widthCount; j++)			{				obstacle = new GameObject ();				obstacle.transform.position = tempPos;				obstacle.transform.parent = obstacleArray.transform;				obstacle.AddComponent 
     
      ();				NavMeshObstacle navMeshObstacle = obstacle.GetComponent
      
        ();				if (navMeshObstacle)				{					obstacle.GetComponent
       
         ().radius = Diameter / 2;					obstacle.GetComponent
        
          ().height = Height;				}				tempPos = new Vector3 (tempPos.x, tempPos.y, tempPos.z + Diameter + widthStep);			}			tempPos = new Vector3 (tempPos.x + Diameter + lengthStep, tempPos.y,  Z);		}		obstacleArray.transform.parent = this.transform;		obstacleArray.transform.localRotation = Quaternion.identity;		obstacleArray.transform.position = this.transform.position;	}	// Update is called once per frame	void Update () {		}}
