Cannot Send Class Object From One Scene to Another-CodePudding

I’m developing a Unity game. I have a login scene in the game that fetches user information from the database. After fetching the user information, a model class which is named as RegisteredUser is used to hold the user credentials. I need to send the created RegisteredUser class object to the next scene. But I cannot send it directly. When I try it, I get NullExceptionError and the object is lost. How can I fix it? This is the callback function that user credentials are returned:

   public void userInfo (RegisteredUser newUser)
{
    loggedinUser.FirstName = newUser.FirstName;
    loggedinUser.LastName = newUser.LastName;
    loggedinUser.Email = newUser.Email;
    loggedinUser.Gender = newUser.Gender;


}

And this is the part where I want to fetch the name and surname of the user to print on the text field:

 void Start()
{
  //  string userName = currentUser.FirstName   currentUser.LastName;
    welcomeText = GameObject.Find("Canvas/SidebarPanel/WelcomeText").GetComponent<Text>();

}

CodePudding user response：

Store your object in a field/property of a MonoBehaviour script that is marked DontDestroyOnLoad.

This object will persist and so will its data.

public class PersistentDataContainer : MonoBehaviour
{
    public RegisteredUser UserInfo;

    private void Awake()
    {
        DontDestroyOnLoad(gameObject);
    }
}
