NullReferenceException: UnityEngine.Object

If you want to handle the case where the object is unassigned:

Check the reference isn't null before trying to access it

Exit early if null.

if (example == null)
{
    // Exit early.
    return;
}
// Code that uses example.

Nest your code in a null check.
```
if (example != null)
{
    // Code that uses example.
}
```

warning

Do not use modern null-checking operators¹ (?., ??, ??=) to check for null.

If you want to correctly assign the object:

Find the cause of `null` values
