unity报错：UnassignedReferenceException: The variable phoenix of VirtualButtonEventHandler has not been assigned. You probably need to assign the phoenix variable of the VirtualButtonEventHandler script in the inspector. VirtualButtonEventHandler.Start () (at Assets/EasyAR/Resources/Scripts/VirtualButtonEventHandler.cs:17)

这个错误提示说明你在 VirtualButtonEventHandler.cs 脚本中使用了变量 phoenix，但是该变量未在代码中被初始化或者赋值。你需要在代码中将该变量赋值，或者在 Unity Inspector 界面中将该变量赋值。

你可以在 VirtualButtonEventHandler.cs 脚本中找到第 17 行代码并检查代码中是否有 phoenix 变量的声明或者初始化语句。如果没有，你可以在代码中添加该变量的声明和初始化语句：

public GameObject phoenix;

void Start() {
    phoenix = GameObject.Find("Phoenix"); // 将 phoenix 变量初始化为场景中名为 "Phoenix" 的 GameObject
}

如果你已经在代码中初始化了 phoenix 变量，那么你可以在 Unity Inspector 界面中将该变量赋值。在 Inspector 界面中找到 VirtualButtonEventHandler 组件，将 phoenix 变量拖拽到该组件的相应字段中即可解决问题。

UnassignedReferenceException: The variable MapLoadFather of GlobalVariable has not been assigned. You probably need to assign the MapLoadFather variable of the GlobalVariable script in the inspector. UnityEngine.GameObject.GetComponent[T] () (at <e17bcb11

这是一个Unity引擎中常见的错误，意思是GlobalVariable脚本中的MapLoadFather变量未被赋值。你需要在Unity编辑器中找到GlobalVariable脚本，并在其属性面板中将MapLoadFather变量赋值为正确的GameObject。如果你不确定应该赋值什么，可以尝试查看代码中是否有对MapLoadFather变量的赋值语句，或者查看文档或教程中的相关说明。

UnassignedReferenceException:+The+variable+sphere+of+follow+has+not+been+assigned. You+probably+need

UnassignedReferenceException is an error that occurs in Unity when a variable has not been assigned a value before it is used. In the given example, the variable "sphere" of "follow" has not been assigned a value.

To fix this error, you need to ensure that the variable "sphere" is assigned a valid value before it is used. This can be done by either assigning a value to the variable directly or by using a reference to an existing object.

Here are a few possible solutions:

1. Assign a value to the variable "sphere" before using it:

   public GameObject sphere; // Declare the variable
   void Start()
   {
       sphere = GameObject.Find("Sphere"); // Assign a value to the variable
   }

2. Drag and drop the desired object onto the script component in the Unity editor:
- Create a public field for the variable "sphere" in the script.
- In the Unity editor, select the object you want to assign to "sphere".
- Drag and drop the object onto the script component that contains the "sphere" variable.

3. Use GetComponent to find and assign the object at runtime:

   public GameObject sphere; // Declare the variable
   void Start()
   {
       sphere = GetComponent<GameObject>(); // Assign a value to the variable
   }

Remember to adjust the code according to your specific use case and object names.
