Triggering random sound on player
I'm using the following script to trigger one of a group of random sounds when I enter a trigger zone. The sounds are coming from the same game object.
I want to do something similar, but have the trigger zone trigger sounds on the Player rather than from that game object. I also want it to cycle through the different sounds rather than just playing one and stopping, with a small wait period between each sound, and for it to stop when I leave the zone.
I've played around with other other.gameObject.GetComponent but I don't quite understand it. :/
Any help is greatly appreciated!
var isPlaying : boolean = false;
var thisSound : AudioSource;
var myClips : Object[];
var sounds: AudioClip[];
function OnTriggerEnter(){
if(isPlaying == false){
isPlaying = true;
audio.clip = sounds[Random.Range(0,sounds.length)];
audio.Play();
}
}
function OnTriggerExit(){
if(isPlaying == true){
isPlaying = false;
}
}
You shouldn't need GetComponent at all, but what you do need is a Coroutine.
using UnityEngine;
using System.Collections;
[RequireComponent(typeof(AudioSource), typeof(SphereCollider))]
public class RandomSoundPlayer : MonoBehaviour
{
public AudioClip[] clips;
#region Unity
void OnValidate()
{
collider.isTrigger = true;
}
void OnTriggerEnter()
{
if (containedColliderCount++ == 0)
StartCoroutine(PlayRandomSound());
}
void OnTriggerExit()
{
if (--containedColliderCount == 0)
StopPlaying();
}
#endregion
#region Private
private int containedColliderCount;
private AudioClip RandomClip
{
get
{
return clips[(int)(Random.value * clips.Length)];
}
}
void StopPlaying()
{
audio.Stop();
}
void PlayClip(AudioClip clip)
{
audio.clip = clip;
audio.Play();
}
IEnumerator PlayRandomSound()
{
while (containedColliderCount > 0)
{
if (!audio.isPlaying)
PlayClip(RandomClip);
yield return null;
}
StopPlaying();
}
#endregion
}
What happens is that you add your clips, then start a coroutine when the first collider, and only the first collider, enters your trigger. This coroutine monitors the playing state of your audio source, and picks a new random clip to play if it isn't playing. When the last contained collider exits your trigger, you stop playing your sound.
