为什么此音频源不播放任何内容？

Question

我正在尝试编写一个脚本，其中音频源播放一个包含 4 个声音的音频剪辑数组。当我的角色冲刺时，声音会播放得更快、更大声，而当我的角色蹲下时，声音会播放得更安静、更慢。我的问题是音频源不播放音频片段。我检查了很多次，确实找不到问题。

`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;
        }
    }
}

Answer 1

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
        }
    }
}
