Why is this audio source not playing anything?

Question

Im trying to write a script where the audio source plays an audioclip array with 4 sounds in it. The sounds are gonna be played faster and louder when my character is sprinting and quieter and slower when my character is crouching. My problem is that the audiosource doesn't play the audioclip. I've checked it multiple times and I really can't find the problem.

`public class PlayerFootsteps : MonoBehaviour { private AudioSource footstepSound;

[SerializeField]
private AudioClip[] footstepClip;

private CharacterController charController;

[HideInInspector]
public float VolumeMin, VolumeMax;

private float accumulatedDistance;

[HideInInspector]
public float stepDistance;


void Awake()
{
    footstepSound = GetComponent<AudioSource>();
    charController = GetComponentInParent<CharacterController>();
}

void Update()
{
    CheckToPlayFootstepSounds();
}

void CheckToPlayFootstepSounds()
{
    if (!charController.isGrounded)
    {
        return;
    }

    if (charController.velocity.magnitude > 0)
    {
        accumulatedDistance += Time.deltaTime;

        if (accumulatedDistance > stepDistance)
        {
            footstepSound.volume = Random.Range(VolumeMin, VolumeMax);

            footstepSound.clip = footstepClip[Random.Range(0, footstepClip.Length)];

            footstepSound.Play();

            accumulatedDistance = 0f;
        }
        else
        {
            accumulatedDistance = 0f;
        }
    }
}

}`

            playerMovement.speed = moveSpeed;

            isCrouching = false;
        }
        else
        {
            lookRoot.localPosition = new Vector3(0f, crouchHeight, 0f);
            playerMovement.speed = crouchSpeed;

            playerFootsteps.stepDistance = crouchStepDistance;
            playerFootsteps.VolumeMin = crouchVolume;
            playerFootsteps.VolumeMax = crouchVolume;

            isCrouching = true;
        }
    }

Answer 1

The problem is that you are setting the accumulatedDistance to 0, This should fix your problem:

void CheckToPlayFootstepSounds()
{
    if (!charController.isGrounded)
    {
        return;
    }

    if (charController.velocity.magnitude > 0)
    {
        accumulatedDistance += Time.deltaTime;

        if (accumulatedDistance > stepDistance)
        {
            footstepSound.volume = Random.Range(VolumeMin, VolumeMax);

            footstepSound.clip = footstepClip[Random.Range(0, footstepClip.Length)];

            footstepSound.Play();

            accumulatedDistance = 0f;
        }
        else
        {
            // accumulatedDistance = 0f; Remove This
        }
    }
}
