Sound

Things we need for sound

• Audio listener
  • To “hear” the audio
  • Almost always on the main camera

  • There always has to be an Audio Listener somewhere in your scene
• Audio Source
  • To “play” the audio
  • On the source that is generating the sound
    • Audio source component on rocket making thrusting sounds
  • https://docs.unity3d.com/ScriptReference/AudioSource.html
• Audio file

• Make sure Project Settings > Audio > System Sample Rate is set to 1 not 0 (if it’s 0 it won’t play)

[SerializeField] AudioClip mainEngine;
AudioSource audioSource;
 
// in some function
audioSource.PlayOneShot(mainEngine);
