loading screen system

hi everyone.

i^m working on a door system where when you are in front of a door and you press "M" key on keyboard, you are able to be transformed in another place, and it`s working good, but what i need is a black screen betwenn this.
open door ---> black screen,play door sound ----> new room.

what i did is the following code, that works, but with a issues.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class DoorSystem : MonoBehaviour {
6.  
7.     public Vector3 newPosition;
8.  
9.     public Camera from;
10.    
11.     public Camera loading;
12.     public Camera to;
13.  
14.     public AudioSource doorSound;
15.  
16.     public float waitTime;
17.  
18.  
19.  
20.  
21.  
22.     void Start () {
23.         doorSound = GetComponent<AudioSource>();
24.  
25.     }
26.  
27.  
28.     void OnTriggerStay (Collider other) {
29.     if(other.CompareTag("Player")&& Input.GetKeyDown(KeyCode.M)) {
30.         StartCoroutine(loadingScreen());
31.         other.gameObject.transform.position = newPosition;
32.  
33.        
34.        
35.        
36.     }
37.     }
38.  
39.     IEnumerator loadingScreen () {
40.         from.gameObject.SetActive(false);
41.         loading.gameObject.SetActive(true);
42.         doorSound.Play();
43.         yield return new WaitForSeconds(waitTime);
44.         loading.gameObject.SetActive(false);
45.         to.gameObject.SetActive(true);
46.        
47.     }

the problem is, if you press any key this is going to be skipped, and the door sound is still played.

i want something that allow me to skip the back loading screen, and stop the audioclip, but when i press and specific key.

someone have any idea to how to do it?

 

This doesn't make any sense on it's own. There is no skipping logic in what you have shown.
