使用基于图层的碰撞球体c# Unity显示对象时遇到麻烦

我在让游戏机制正确运行时遇到了一些问题。基本上我有两个区域:Collidersight和Colliderfatal，它们是由连接在炮弹上的碰撞球定义的，炮弹是由大炮发射的。从本质上讲，我希望任何在Collidersight区域内的物体只要在该特定区域内就会被显示，如果它们在该区域外，它们应该返回到不可见状态。如果一个对象与Colliderfatal碰撞，那么该对象应该永久显示，即使在shell被销毁之后。我已经尝试单独初始化游戏对象，但这似乎非常令人困惑，不适用于这种情况。游戏对象已经存在于场景中，我没有实例化它们。有人告诉我，我可能需要创建一个游戏对象列表来在碰撞球中循环，作为这个问题的潜在解决方案，但我完全不知道如何实现这一点。

代码如下:

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

public LayerMask  s_FatalityLayers;

    public float s_Radius;
    public Vector3 s_Position;
    public Invisible1 revealenemy1;
    public Invisible1 enemykill1; 
    public float s_Force;
    public InvisibleKill makeDead;
    public GameObject EnemyCube1; 
    //public GameObject enemydead; 
    bool hasExploded;
    public bool inZone;
    public bool inKillzone;
    //public float removeTime = 5.0f;
    bool hasBeenhit;
    void Awake(){
    GameObject[] objects = GameObject.FindGameObjectsWithTag("Enemy");  
    }

    void start (){
    makeDead = (InvisibleKill) EnemyCube1.GetComponent (typeof(InvisibleKill));
    revealenemy1 = (Invisible1) EnemyCube1.GetComponent(typeof(Invisible1));    
    }
    void OnCollisionEnter(Collision explode){
        if(explode.gameObject.name == "Terrain" || explode.gameObject.name == "EnemyCube" || explode.gameObject.name == "EnemyCube1" ){
            hasExploded = true;
        }
    }
    void FixedUpdate ()
    {
