Unity 扭曲音频

Unity 扭曲音频

c#unity-game-engineaudio-player

3

我在Unity中播放音频片段时遇到了问题。

当检测到玩家时，我希望我的鲨鱼能够发出“咬”的声音，但声音却变形了。

其余的代码都按预期运行。

请问我能够进行代码审查并提供建议吗？

我可能在哪里出了错（调用音频源播放时）？

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Shark2Controller : MonoBehaviour {

    public Transform leftPoint;
    public Transform rightPoint;

    public float startSpeed;
    public float swimSpeed;
    private Rigidbody2D myRigidBody;
    public bool swimmingRight;


    public float superSpeed;
    public Transform puntoA;
    public Transform puntoB;
    public LayerMask whatIsPlayer;
    public bool playerDetected;

    private Animator myAnim;

    public AudioSource bite;

    // Use this for initialization
    void Start ()
    {
        myRigidBody = GetComponent<Rigidbody2D> ();
        myAnim = GetComponent<Animator>();
        swimSpeed = startSpeed;
    }

    // Update is called once per frame
    void Update () 
    {
        playerDetected = Physics2D.OverlapArea (puntoA.position, puntoB.position, whatIsPlayer);
        myAnim.SetBool ("Player Detected", playerDetected);

        if (playerDetected) 
        {
            swimSpeed = superSpeed;
            bite.Play ();
        } 


        if (swimmingRight && transform.position.x > rightPoint.position.x) 
        {
            swimmingRight = false;
        }

        if (!swimmingRight && transform.position.x < leftPoint.position.x) 
        {
            swimmingRight = true;
        }



        if (swimmingRight) 
        {
            myRigidBody.velocity = new Vector3 (swimSpeed, myRigidBody.velocity.y, 0f);
            transform.localScale = new Vector3 (1f, 1f, 1f);
        }
        else 
        {
            myRigidBody.velocity = new Vector3 (-swimSpeed, myRigidBody.velocity.y, 0f);
            transform.localScale = new Vector3 (-1f, 1f, 1f);
        }
    }

    public void ResetShark2Speed()
    {
        swimSpeed = startSpeed;
    }
}

但声音变形了。是哪种变形，音量级别的扭曲吗？此外，bite.Play(); 应该在每个帧更新时触发吗？如果您的FPS为60，您真的想让 bite 每秒播放60次吗？那听起来不太好，我期望会有（可能的）嗡嗡声/卡顿的噪音……也许这就是你所说的变形？ - VC.One

没错，那是嗡嗡声。非常感谢您的解释，我之前对在Update()期间使用Audio Source不太清楚。 - Rub

我看到的一个问题是，你在每次屏幕更新时都会重新播放声音（根据应用程序的帧率）。不清楚你是否想要循环播放它（因为它被放置在void Update函数中以重复指令），还是只想要每次检测时播放一次。

如果Unity可以检测到声音何时正在播放或已完成，则可以使用它来帮助解决此问题。

循环逻辑如下：

- 在每个帧更新时，检查声音是否已处于“播放”模式。 - 如果没有...假设声音“结束”，现在可以执行bite.Play();。 - 否则-如果是...让声音继续（也许它将在将来的帧检查中“结束”）。

伪代码示例：

if (playerDetected == true) 
{
    swimSpeed = superSpeed;

    if( bite.isPlaying == true)
    {
        //# Do nothing or whatever you need
    }
    else 
    {
        //# Asssume it's not playing (eg: stopped, ended, not started, etc)
        bite.Play (); 
    }
}

对于一次检测：

public bool detect_snd_Played;

detect_Snd_Played = false;  //# Not yet played since no "detect"

//# Update is called once per frame
void Update () 
{
    if (playerDetected == true) { swimSpeed = superSpeed; }

    if (detect_Snd_Played == false) 
    {
        bite.Play ();
        detect_Snd_Played = true; //# Stops future playback until you reset to false
    }
}

这行代码 detect_Snd_Played = true; 应该能够防止多次播放直到你重置。这可能是因为你的播放器被鲨鱼“未检测”了，现在你可以为下一次新的“检测”过程进行重置…
