Newbie Question about Unity

Questions & Answers

Hello to Everyone.I am working on a 2D Platform game and i have a problem.I have this code:

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

[RequireComponent (typeof(AudioSource))]

public class spawnDoor : MonoBehaviour {

	public MovieTexture movie;
	private AudioSource audio;
	public Transform WhereToSpawn;
	public GameObject door;

	// Use this for initialization
	void Start () {
		
	    GetComponent<RawImage> ().texture = movie as MovieTexture;
		audio = GetComponent<AudioSource> ();
		audio.clip = movie.audioClip;
		movie.Play ();
		audio.Play ();
	}
	
	// Update is called once per frame
		void Awake () {
		if (Input.GetKeyDown (KeyCode.Space) && movie.isPlaying) {
			movie.Pause ();
		} else if (Input.GetKeyDown (KeyCode.Space) && !movie.isPlaying) {
			movie.Play ();
		}
	}

	void OnTriggerEnter2D(Collider2D other){
		if (other.tag == "Player") {
			SceneManager.LoadScene("PlayVideo");
			Instantiate (door, WhereToSpawn.position, Quaternion.identity);
			Destroy (gameObject);
		}
	}
}

And i am getting this error:
NullReferenceException: Object reference not set to an instance of an object
spawnDoor.Start () (at Assets/Scripts/spawnDoor.cs:19)

I understand that the problem is in line 19 but it seems good to me.I can’t see any mistake.Please help me.

void Start () {
if (GetComponent () != null && movie != null)
{
GetComponent ().texture = movie as MovieTexture;
audio = GetComponent ();
audio.clip = movie.audioClip;
movie.Play ();
audio.Play ();
}
}

@dimitrakis1992 change

[RequireComponent (typeof(AudioSource))]

to

[RequireComponent (typeof(AudioSource))]
[RequireComponent (typeof(RawImage))]

And in the code by @RobAnthem you want to do this

  void Start () {
      var rawImage = GetComponent<RawImage>();
      if (rawImage != null && movie != null)
     {
          rawImage.texture = movie as MovieTexture;
          audio = GetComponent<AudioSource> ();
          audio.clip = movie.audioClip;
          movie.Play ();
          audio.Play ();
     }
  }

Note how instead of using GetComponent twice I have called it once and assigned the value to a local variable and used that instead.
