unity的小问题， 这一句是不是多此一举

Question

private void SetCameraTargets()
{
// Create a collection of transforms the same size as the number of tanks.
Transform[] targets = new Transform[m_Tanks.Length];

    // For each of these transforms...
    for (int i = 0; i < targets.Length; i++)
    {
        // ... set it to the appropriate tank transform.
        targets[i] = m_Tanks[i].m_Instance.transform;
    }

    // These are the targets the camera should follow.
    m_CameraControl.m_Targets = targets;
}


            接收的目的让相机显示所有的物体
            相机的CameraContral带一个求重心和缩放的功能

            为什么要new一个target呢
