AI案列 三条路

在生成点生成带有颜色的小球，小球走对应颜色的路

先做好三个小球，做成预制体

对应颜色的小球，除了自身颜色，其他颜色不要选

新建脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class xunlu002 : MonoBehaviour {
    public float time = ;
    public Transform target;
    public Transform tr;//生成点
    public GameObject[] obj = new GameObject[];
    private NavMeshAgent agent;
    GameObject go;
    List<GameObject> c = new List<GameObject>();

    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {
        time += Time.deltaTime;
        if (time > )
        {

             go = Instantiate(obj[Random.Range(, obj.Length)], tr.position, Quaternion.identity);
            go.GetComponent<NavMeshAgent>().destination = GameObject.Find("target").transform.position;

            c.Add(go);
            time = ;

        }
        foreach (GameObject item in c)
        {
            if (Vector3.Distance( item.transform.position, target.position) <= 1.1f)
            {
                Destroy(item,);
                c.Remove(item);
            }

        }
        }

    }
