AudioSource.PlayClipAtPoint

[Griffo]

Hi, I have a problem that I hope someone can help me with, I want to play a sound where an RPG hits the ground, so what I have done is made an RPG from the basic game object cylinder, then I dragged it into the prefab folder to make a prefab from it.

I then initiate the prefab when I fire the RPG and it fires fine, I’ve added a audio source to the RPG with the setting as 3D, Custom RollOff with a distance of 30, also attached to the RPG prefab is a script that initiates an explosion when colliding with anything and I also thought it would play the explosion sound at the same point, this is the bit of code I use to initiate the explosion and sound -

function OnCollisionEnter(collision : Collision) {

	if(!loop){
		loop = true;	// Set loop to true so this destroyRPG() function dont keep repeating

		var contact : ContactPoint = collision.contacts[0];
		var rot : Quaternion = Quaternion.FromToRotation(Vector3.up, contact.normal);

// Instantiate the explosion and fireball facing away from the impact point
    	Instantiate(explosion, transform.position + Vector3(0, -0.15, 0), rot);
   		Instantiate(rpgExplosion, transform.position + Vector3(0, 0, 0), rot);
   		
		AudioSource.PlayClipAtPoint(explosionSound, collision.contacts[0].point);

		destroyRPG();
	}
}

But no matter where the RPG lands the sound is constant, is this incorrect ?

The audio source itself does not decide wether it plays a 3d sound or a 2d sound. You have to mark the clip itself as 3d or 3d sound. Select the audio clip in the project panel and check the corresponding check box in the inspector.

Furthermore AudioSource.PlayClipAtPoint creates its own AudioSource and destroys it automatically when the clip is finished. So you don’t need to attach a AudioSource component to your RPG.
