Do I have to create an audio source component to play a sound from script?
I want to play sounds from a script that's attached to a prefab. I'm confused because it seems like to do something like this:
var RumbleSound : AudioClip;
function Start()
{
audio.PlayOneShot(RumbleSound);
}
I have to add an audio source component to the prefab that the script is attached to. There doesn't have to a clip loaded in the audio source, but I definitely have to make an audio source.
I need to be able to add several sounds to the script, which is why I'm not just playing audio from the audio source itself.
There are three ways to play a sound:
1- Play(), which plays the sound currently stored in the AudioSource clip property (requires an AudioSource). You can declare several AudioClip variables or an AudioClip[] array, fill them at the Inspector, assign the sound you want to audio.clip and call audio.Play();
2- PlayOneShot(clip, vol), which plays the sound clip with volume vol - still requires an AudioSource. You can use the same procedure above to define the sounds, but there's no need to use the clip property, since you pass the AudioClip as a parameter;
3- PlayClipAtPoint(clip, point, vol), as @Molix suggested. You don't need an AudioSource because this function creates a temporary instance and kill it right after. It's useful when you don't want to create an AudioSource, or if you want the sound to play at a specific location;
NOTE: Only Play() affects and is affected by the audio source variables (pitch, isPlaying, loop etc.). If you need to change any of these characteristics or check isPlaying, use Play.
