Help with respawning and Game Over sounds

I am making a simple script which makes the player respawn when he falls. The actual respawning part works, but I have tried to add a 'Game Over' sound that plays straight after respawning. Everytime I respawn, the sound does play, but it also plays straight after starting the game up.

Here's the script:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class BallHealth : MonoBehaviour {
5.    
6.     public bool isRestarting = false;
7.     public float maxFallDistance = -10f;
8.     public AudioClip GameOver;
9.  
10.     void Update ()
11.     {
12.         if (transform.position.y < maxFallDistance)
13.         {
14.             if(isRestarting == true)
15.             {
16.                 AudioSource audio = GetComponent<AudioSource>();
17.                 audio.Play ();
18.             }
19.             isRestarting = true;
20.             Application.LoadLevel("Level01");
21.         }
22.     }
23. }

As I said, the sound does play when I respawn, but it also plays when I start the scene up. Any ideas why?

 

That's because on your Audio Source component you have "Play on Awake" checked. Disable that and it will be fine.

 

Well, now the sound doesn't play when I start up the scene, but neither does it play when I respawn, as if it was completely disabled...

All I changed was the 'Play On Awake'...

 

hmm odd... another option could be to just stop the audio to begin with and leave it checked

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class BallHealth : MonoBehaviour {
6.  
7.     public bool isRestarting = false;
8.     public float maxFallDistance = -10f;
9.     public AudioClip GameOver;
10.  
11.     private AudioSource audio;
12.  
13.     void Start()
14.     {
15.         audio = GetComponent<AudioSource>();
16.         audio.Stop();
17.     }
18.  
19.     void Update ()
20.     {
21.         if (transform.position.y < maxFallDistance)
22.         {
23.             if(isRestarting == true)
24.             {
25.                 audio.clip = GameOver;
26.                 audio.Play ();
27.                 isRestarting = false;
28.                 Application.LoadLevel("Level01");
29.             }
30.         }
31.     }
32. }
33.  

 

That's because when you respawn you don't call anything, you just spawn the gameobject. On your Start() you should call Play() on the AudioSource component.

 

Could it be that because I'm loading the whole level, the script is also reloaded?
This would mean that the variable isRestarting is always false...

I'm not that sure though.

 

Fixed it:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class BallHealth : MonoBehaviour {
5.  
6.     public float maxFallDistance = -10f;
7.  
8.     void Update ()
9.     {
10.         if (transform.position.y < maxFallDistance)
11.         {
12.             GetComponent<AudioSource>().Play();
13.             transform.position = new Vector3(0, 1, 0);
14.         }
15.     }
16. }

The 'new Vector3' on line 13 is the starting position of the player.

 

Indeed. The script is getting reloaded.

You can avoid that by using :

Code (CSharp):

1. private void Start()
2. {
3.      DontDestroyOnLoad(gameObject);
4. }

This will allow your gameObject to stay in the game even when you load another scene.

 

It's not cool to use GetComponent in Update(), as it is a slow method.

You should change it like that :

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class BallHealth : MonoBehaviour {
5.  
6.     public float maxFallDistance = -10f;
7.  
8.     private AudioSource audioSource;
9.  
10.     void Start ()
11.     {
12.         audioSource = GetComponent<AudioSource>();
13.     }
14.  
15.     void Update ()
16.     {
17.         if (transform.position.y < maxFallDistance)
18.         {
19.             audioSource.Play();
20.             transform.position = new Vector3(0, 1, 0);
21.         }
22.     }
23. }
