为什么这个音频源不播放任何东西?

Question

我试图写一个脚本，其中音频源播放一个audioclip数组与4个声音在它。当我的角色冲刺时，声音会播放得更快更响，而当我的角色蹲下时，声音会播放得更安静更慢。我的问题是audiosource不播放audioclip。我检查了好几遍，还是找不到问题。

` ` ` ` ` ` player脚步声: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 = crouchSpeed;
playerFootsteps.stepDistance = crouchStepDistance;

问题是您将accumulatedDistance设置为0，这应该可以解决您的问题:

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
}
}
}
