unity3d 实现LOL英雄的寒冰的（万箭齐发）

先上效果图

放到人物身上的脚本Thefanattacks

public class Thefanattacks : MonoBehaviour

    public string BulletOrigin;//子弹父类的路径
    public string bulletModelPath; //子弹模型路径

    public int interval;//间隔（间隔最好是Mathf.Abs(count / interval)*2 的偶数，负的也许只不过有一些偏差）
    Vector3[] vectors;//数组

    void Start()

        int number = Mathf.Abs(count / interval)*2;

    // Update is called once per frame

                    var bulletOriginGo = GameObject.Instantiate(prefabBulletOrigin, bornPos, bornDir);//实例化

子弹的移动脚本Move

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

public class Move : MonoBehaviour
{
    public int speet;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        transform.Translate(transform.forward*Time.deltaTime* speet,Space.World);
        Destroy(gameObject, 5);
    }
}
