Unity3d C＃ - 寻找第二最接近的立方体

Question

我有此脚本查找当前最接近的立方体：

GameObject FindClosestCube() { 

    GameObject[] gos; 
    gos = GameObject.FindGameObjectsWithTag("cube"); 
    GameObject closest = null; 
    float distance = Mathf.Infinity; 
    float position = transform.position.z; 
    foreach (GameObject go in gos) { 
     float diff = go.transform.position.z - position; 

     float curDistance = diff; 
     if (curDistance < distance) { 
      closest = go; 
      distance = curDistance; 
     } 
    } 
    return closest; 
} 

现在我想获得第二近的立方体，所以最接近的立方体后最接近的立方体（Z-轴）。我尝试了几件事，但他们没有工作，所以有人可以解释我如何实现这一目标？谢谢。

在分配一个新的最接近之前，分配最接近第二个最接近的当前值。 然后返回一个游戏对象数组，第一个元素是最接近的。

GameObject[] FindClosestCubes() { 
    GameObject[] gos; 
    gos = GameObject.FindGameObjectsWithTag("cube"); 
    GameObject closest = null; 
    GameObject secondClosest = null; 
    float distance = Mathf.Infinity; 
    float position = transform.position.z; 
    foreach (GameObject go in gos) { 
     float diff = go.transform.position.z - position; 

     float curDistance = diff; 
     if (curDistance < distance) { 
      secondClosest = closest; 
      closest = go; 
      distance = curDistance; 
     } 
    } 
    return new GameObject[] { closest, secondClosest }; 
}
