在lookObjects中，我有两个立方体，每个立方体都以不同的速度围绕玩家旋转，但玩家只会查看lookObjects列表中的第二个立方体，而不会查看第一个立方体。
我想让玩家知道根据最近的一个在lookObjects之间切换，因为现在即使第二个立方体在玩家后面，他也没有看它，它也不会切换到玩家前面的第一个立方体。
逻辑应该是，如果其中一个立方体在玩家视线之外，如果另一个在玩家视线内，则切换到另一个。
-
为什么它不在lookObjects之间切换?
-
如果两个立方体(lookObjects)都在玩家面前该怎么办?如何决定看哪一个?这种情况下的逻辑应该是什么?

}
}
创建for循环在每次变换上使用Vector3.Distance(Transform A, Transform B)来获得外观顺序然后可以使用transform.LookAt(Transform target)查看对象
