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.
