C＃Unity Raycast問題，相機沒有響應

Question

我在我的播放器和相機之間創建了一個光線廣播，當它檢測到一個命中時，將相機移動到對象的前面，以便該對象不會阻擋視圖。

調試測試顯示raycast肯定正在工作。然而，我從控制檯得到的關於我的代碼的唯一消息是變量targetMoveUse被賦值，但其值永遠不會被使用。

我從youtube上的教程中學習了這段代碼，並且將它跟在一個tee上，但儘管看起來和教程有相同的代碼，但它並不適合我。本教程僅供參考：https://www.youtube.com/watch?v=0nI0rX5fEY0

這是我的代碼。任何幫助表示讚賞。

Transform player; 
Quaternion targetLook; 
Vector3 targetMove; 
public float rayHitMoveInFront = 0.1f; 
Vector3 targetMoveUse; 
public float smoothLook = 0.5f; 
public float smoothMove = 0.5f; 
Vector3 smoothMoveV; 
public float distFromPlayer = 5; 
public float heightFromPlayer = 3; 

void Start() { 
    player = GameObject.FindWithTag ("Player").transform; 
} 

void Update() { 
    targetMove = player.position + (player.rotation * new Vector3 (0, heightFromPlayer, -distFromPlayer)); 

    RaycastHit hit; 
    if (Physics.Raycast (player.position, targetMove - player.position, out hit, Vector3.Distance (player.position, targetMove))) 
     targetMoveUse = Vector3.Lerp (hit.point, player.position, rayHitMoveInFront); 
    else 
     targetMoveUse = targetMove; 

    //chapter 4 episode 3 part 1 
    //transform.position = player.position + (player.rotation * new Vector3 (0, heightFromPlayer, -distFromPlayer)); 


    //transform.position = Vector3.Lerp (transform.position, targetMove, smoothMove * Time.deltaTime); 

    transform.position = Vector3.SmoothDamp (transform.position, targetMove, ref smoothMoveV, smoothMove); 

    targetLook = Quaternion.LookRotation (player.position - transform.position); 
    transform.rotation = Quaternion.Lerp (transform.rotation, targetLook, smoothLook * Time.deltaTime); 
    //chapter 4 episode 1 
    //transform.LookAt (player); 
} 

}

Answer 1

檢查這條線，

transform.position = Vector3.SmoothDamp (transform.position, targetMove, ref smoothMoveV, smoothMove); 

與targetMoveUse

transform.position = Vector3.SmoothDamp (transform.position, targetMoveUse, ref smoothMoveV, smoothMove);
