Contents of an Input Field equal to a Placeholder in another scene and script, error?

Questions & Answers

I would like to set the contents of the Input Field equal to a placeholder in another script and scene, when the user presses Enter. I keep Getting an Error. The code looks fine to me, however I am new to C#.

Script #1

/*
* Project> InfCreations-IV
*/

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
using System.Collections;
using System;

public class StartDisplay : MonoBehaviour
{

    [Header("Start Display")]
    public Text FlashingText;
    public string[] stringText;
    public Text Arrow;
    public GameObject UserField;
    public InputField input;

    [SerializeField]
    private Animator animator;

    public float speed = 0.05f;

    int StringIndex = 0;
    int CharacterIndex = 0;

    void Start () 
    {
	    StartCoroutine(Transition());
	    UserField.SetActive(false);
    }

    IEnumerator Transition ()
    {
	    Arrow.canvasRenderer.SetAlpha(0f);

	    while (1 == 1)
	    {
	            yield return new WaitForSeconds(speed);
		    FlashingText.text = stringText[StringIndex].Substring(0, CharacterIndex);
		    speed += Time.fixedDeltaTime;
		    CharacterIndex++;
		    if (CharacterIndex > stringText[StringIndex].Length)
		    {
			    Arrow.CrossFadeAlpha(1f, speed, false);
			    UserField.SetActive(true);
		    }

		    if (CharacterIndex++ == 19)
		    {
			    animator.SetTrigger("MoveUp");
			    yield return false;
			    yield break;
		    }
	    }
    }

    void Update()
    {
	    if (input.text != null)
	    {
		    if (Input.GetKeyDown(KeyCode.Return))
		    {
			    StartCoroutine(LoadMainMenu());
			    return;
		    }
	    } else
	    {
		    return;
	    }
    }

    IEnumerator LoadMainMenu()
    {
	    yield return new WaitForSeconds(0f);
	    Arrow.CrossFadeAlpha(0f, speed, false);
	    UserField.transform.position = new Vector3(1000, 1000, 1000);
	    yield return new WaitForSeconds(1f);
	    FlashingText.transform.position = new Vector3(1000, 1000, 1000);
	    SceneManager.LoadScene("Loading");
    }
}

Script #2

/*
* Project> InfCreations-IV
*/

using UnityEngine;
using UnityEngine.UI;

public class Loading : MonoBehaviour 
{
    public Text Title;
    private StartDisplay startDis;

    void Start ()
    {
	    Title = FindObjectOfType<Text>();
	    startDis = FindObjectOfType<StartDisplay>();
	    Title.text = startDis.input.text;
    }

}

Inside your StartDisplay script, declare a public variable of type Loading .

 public Loading loadingBehavior;

In the editor, drag your Loading scene object, over this field, which should now be visible in your StartDisplay object. Only GameObjects that contain a Loading component will be valid for drag onto this field. (You could also use the Find function like you do in Loading.Start(), to get this object reference. )

Now you can access any public members of the Loading class, via this field, from inside StartDisplay.

 loadingBehavior.Title.text= "Loading, hang on";

One last note:

It is good practice to not make assumptions, and double check the user: it’s possible that a loadingBehavior has NOT been dragged onto the ‘StartDisplay.loadingBehavior’ field, leaving it blank (null). You should check that the loadingBehavior object is valid, before accessing it’s members, or risk null reference exceptions.

 if(loadingBehavior!=null)
 {
    loadingBehavior.Title.text= "Loading, hang on";
 }
