So, I had my sound all nicely configured before this lecture, where my thrust sound faded in as I pressed Space, and faded out when I released it. Then I had to add in other AudioClips that ran as OneShots. This is my solution. I’d be interested to hear if there’s an easier way:
I have two AudioSources on my player, one of them has the thrust noise set in the inspector, the sounds for the second one are set via PlayOneShot();
I’ve removed the irrelevant bits of code to only show the audio related parts.
AudioSource flyingSound;
AudioSource soundEffectSounds;
[SerializeField] private int FadeInTime; // The time it takes for the audio to fade in.
[SerializeField] AudioClip HurtNoise;
[SerializeField] AudioClip VictoryNoise;
// Use this for initialization
void Start ()
{
AudioSource[] Sounds = GetComponents<AudioSource>();
flyingSound = Sounds[0]; // Already has AudioClip defined in inspector.
soundEffectSounds = Sounds[1];
flyingSound.volume = 0; // I want thrusters sound to not be heard
flyingSound.Play(); // I want the audio to loop constantly, and fade in/out when needed
}
// Update is called once per frame
void Update ()
{
if (state == State.Alive)
{
RespondToRotateInput();
RespondToThrustInput();
}
else FadeOut(); // Fade out thrust sound if not alive.
}
void OnCollisionEnter(Collision collision)
{
if (state != State.Alive)
{
return;
}
switch (collision.gameObject.tag)
{
case "Friendly":
break;
case "Finish":
StartSuccessSequence();
break;
default:
StartDeathSequence();
break;
}
}
private void StartSuccessSequence()
{
state = State.Transcending;
soundEffectSounds.PlayOneShot(VictoryNoise);
Invoke("LoadNextLevel", 1f); // TODO chance time parameter to a variable
}
private void StartDeathSequence()
{
print("you died");
state = State.Dying;
soundEffectSounds.PlayOneShot(HurtNoise);
Invoke("LoadFirstLevel", 1f);
}
private void RespondToThrustInput()
{
if (Input.GetKey(KeyCode.Space))
{
float thrustThisFrame = thrustFactor * Time.deltaTime;
rigidBody.AddRelativeForce(Vector3.up * thrustThisFrame);
FadeIn(); // If space is pressed, fade in thrust audio
}
else
{
FadeOut(); // If not thrusting, fade out thrust audio
}
}
private void FadeIn()
{
if (flyingSound.volume < 1)
{
flyingSound.volume = flyingSound.volume + (Time.deltaTime / (FadeInTime + 1));
}
}
private void FadeOut()
{
flyingSound.volume = flyingSound.volume - (Time.deltaTime / (FadeInTime + 1));
}
}
