PlayClipAtPoint in Unity 5

[Gabriel_Gallardo]

Hi, so there was this closed post. I encountered the same problem and it looked like a great and simple solution:

Continuing the discussion from PlayClipAtPoint in Unity 5:

PlayClipAtPoint in Unity 5

So for various reasons I am following the course using Unity 5.6.

The problem I have is with the correct Unity 5 c# code for the “crack” sound when the ball hits the bricks.

I have attached an AudioSource to the bricks, if I use the code below the sound will play when it hits a brick and the brick is not destroyed, but not when the brick is destroyed:

GetComponent<AudioSource>().Play();

So this is where in the course it says you should use PlayClipAtPoint, however the below code does not work:

GetComponent<AudioSource>().PlayClipAtPoint();

I know I could put all the audio sounds on the ball, or create a SoundManager, but I just wondered if there was an equivalent to PlayClipAtPoint in Unity 5 so my code can be as close as possible to what is being taught?

Thanks!

The answer:

PlayClipAtPoint in Unity 5

Hi Joh,

The problem you are having is that you are trying to get a component (AudioSource) of a GameObject that has been destroyed, thus, it doesn’t exist.

The method PlayClipAtPoint is a static method, this means that you do not need an instance of the AudioSource in order to use it, e.g. the one on the brick.

As such, you can just use;

AudioSource.PlayClipAtPoint(clip, position, volume);

You will need to obviously have access to the clip, the position would be the position of the brick typically, the volume is optional and will default to 1.0f if you do not specify it.

This method instantiates a new AudioSource GameObject as needed, and destroys it automatically once the clip has finished playing.

Hope this helps

The thing is that if I replace ‘clip’ with ‘crack’ (the name of the audio clip) in the solution then Monodevelop says that it does not belongs to the current context. I guess that’s because of this part of the answer:

PlayClipAtPoint in Unity 5

You will need to obviously have access to the clip

How can I have access to the clip? Maybe I didn’t had enough attention through the lecture, but it wasn’t obvious for me (not the ‘how’ at least), so I’m stuck at this point. Thanks in advance.

Note: I’m actually on Unity 2017.

Hi Gabriel,

clip is the AudioClip. It is the variable declared at the top of the script, you drag the AudioClip into the exposed field in the Inspector. It is the same as crack, just a different named variable.

Perhaps if you post your script?

Thanks for the reply. I followed the instruction and declared an AudioClip variable, deleted the Audio Source component I had in the brick inspector and dragged the clip into the script’s exposed field. It playbacks the sound but the speaker icon still displays in all bricks at the same time, so PlayClipAtPoint doesn’t seem to be working. Here’s my code:

public class Brick : MonoBehaviour {

	private int timesHit;
	private LevelManager levelManager;
	private bool isBreakable;

	public Sprite [] hitSprites;
	public AudioClip clip;

	public static int breakableCount = 0; 

	// Use this for initialization
	void Start ()
	{
		isBreakable = (this.tag == "Breakable");
		//Keep track of breakable bricks
		if (isBreakable) {
			breakableCount++;
		}
		timesHit = 0;
		levelManager = GameObject.FindObjectOfType<LevelManager>();
	}
	// Update is called once per frame
	void Update ()
	{	}

	void OnCollisionExit2D (Collision2D collision)
	{
		if (isBreakable) {
			HandleHits();
			AudioSource.PlayClipAtPoint (clip, transform.position);
		}
	}

	void HandleHits (){
		timesHit = timesHit + 1;
		int maxHits = hitSprites.Length + 1;
		if (timesHit >= maxHits) {
			breakableCount--;
			levelManager.BrickDestroyed (); 
			Destroy (gameObject);
		} else {
			LoadSprites ();
		}
	}

	void LoadSprites ()
	{
		int spriteIndex = timesHit - 1;
		if (hitSprites [spriteIndex]) {
			this.GetComponent<SpriteRenderer>().sprite = hitSprites[spriteIndex];
		}
	}
		// TODO Remove this method once we can actually win
	void SimulateWin (){
		levelManager.LoadNextLevel();
	}
}

Thanks again.

Hi,

You haven’t removed the AudioSource component, you have just disabled it by removing the tick.

You don’t need an AudioSource on the Brick GameObjects so you can just remove it completely. This will also remove the speaker icon inyour Scene view.

It worked perfectly. Thank you so much Rob!

You are very welcome.
