好吧，这是一个听起来很混乱的标题，但我很困，不知道如何用几个词来描述。基本上，我有一个激光的脚本，它可以折射出镜子，游戏的目的是将激光折射到接收器中，一旦第一个充满不同激光的房间与相应的接收器连接，门就会打开。我在Reciever脚本中使用了OnCollisionEnter，然后我发现lineRenderer不能被这个检测到。所以为了测试它，我使用了
if (gameObject.tag == "BLazer")
{
if (hit.collider.tag=="BTarget")
{
GameObject BR11 = GameObject.Find("BlueReceiver11");
Receiver Receiver = BR11.GetComponent<Receiver>();
string TEST= hit.collider.name;
Receiver.HIT = true;
break;
}
但这意味着我必须输入一个检查，并在脚本中为游戏中的每一个接收者输入对象，一定有比这更好的方法。
我在这里附上完整的脚本代码，忽略随机的bool和ints，全部用于测试。

如果因为某种原因，有人遇到了这个问题，而且他们用和我一样的方式来表达，我为你能找到这里的路而感到骄傲，你一定花了不少时间。
我忘了回到这个问题，但如果有人在未来寻找这个问题，并且被卡住了，我所做的是超级不聪明的，非常不可扩展性，但欢迎你去做，如果你正在寻找一个快速和肮脏的解决方案，lol
