Question

我试图在我的项目中为我的汽车制作工作钥匙，但是当我尝试引用另一个脚本时，我得到一个错误说：

NullReferenceException：未将对象引用设置为对象的实例 DrivingScript.Update（）（在Assets / Car /尝试制作自定义Car / DrivingScript.js：21）

我试图查一查，但如果你能帮忙就找不到问题。

 var Car : Transform;
 var player : Transform;
 var exitPoint : Transform;
 var tentplayer : Transform;
 var campfire : Transform;
 var doorTriggerLeft : Transform;
 var PlayerCamera : Camera;
 var CarCamera : Camera;
 var isPlayerVisable : boolean;

private var invScript : Inventory;

  function Start () {
  
  invScript = GetComponent(Inventory);
  
  }
  
  
  function Update (){
     if (CarCamera.enabled == false && invScript.LetDrive == true)
     {
     if (Input.GetKeyDown("r")&& isPlayerVisable){
         //Make player invisable and still standing
         player.gameObject.SetActiveRecursively(false);
         player.gameObject.active = false;
         // Parent player to ExitPoint

             // Parent Exit Point to Door Trigger.
             exitPoint.parent = doorTriggerLeft.transform;
             // Disable car as a controllable

看起来您没有在编辑器中设置CarCamera属性并将其保留为null，而此脚本依赖于它的设置。
