吃到奖励变换子弹的方法

public class hero : MonoBehaviour
{
    public float superGunTime = 10f;
    private float resetSuperGunTime;
    private int GunCount = 1;
    //用fire脚本去声明三个变量来存放三个位置的枪口
    public fire upGun;
    public fire rightGun;
    public fire leftGun;

void Start()
    {
        // player = GameObject.FindGameObjectWithTag("Player").transform;
        resetSuperGunTime = superGunTime;
        superGunTime = 0;
        GunCount = 1;
        upGun.OnFire();
    }

 void Update()
    {

         superGunTime -= Time.deltaTime;
        if (superGunTime > 0)
        {
            if (GunCount==1)
            {
                GunToSuperGun();
                GunCount = 3;
            }

        }
        else
        {
            GunToNormal();
            GunCount = 1;
        }
    }

    private void GunToSuperGun()
    {
         //得到fire脚本的OnFire方法
        rightGun.OnFire();
        leftGun.OnFire();
    }

    private void GunToNormal()
    {
        rightGun.StopFire();
        leftGun.StopFire();
    }

 public void OnTriggerEnter2D(Collider2D collider)
    {

        if (collider.tag=="Award")//判断是否碰到了Tag标签
        {
            print("是Awar");
            Award award = collider.GetComponent<Award>();//得到Award脚本的组件
            if (award.type==1)//判断type的类型
            {
                print("是1");
                superGunTime = resetSuperGunTime;
                Destroy(collider.gameObject);//销毁碰撞到的物体的
            }
        }

    }
}

这里是fire脚本的代码

using System;
using UnityEngine;
using System.Collections;

public class fire : MonoBehaviour
{

    public float rate = 0.2f;
    public GameObject bullet;

    //实例化子弹
    public void Fire()
    {
        GameObject.Instantiate(bullet, transform.position, Quaternion.identity);
    }
    //如何实例化子弹
    public void OnFire()
    {
        InvokeRepeating("Fire",0.1f,rate);
    }

    //停止子弹发射
    public void StopFire()
    {
        //取消invoke的指令
        CancelInvoke("Fire");
    }
}
