Question

在我的另一个问题中，我使用一个混音器，其中两组分别用于游戏场景和主菜单场景。

在主菜单场景中，我有音乐的音频源和 sfx 效果的音频源。当游戏在主菜单中开始时，音乐在唤醒时自动播放。，

sfx 没有播放，我希望当我更改 sfx 滑块时，它会在短时间内发出 sfx 效果，因此每次我更改滑块值时，它都会播放 sfx 以听到音量。

滑块在游戏中的样子：

我还设置音量时的设置脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Audio;
using UnityEngine.UI;
using TMPro;
using System;
using UnityEngine.Events;
using System.Linq;

public class Settings : MonoBehaviour
{
    public AudioMixer audioMixer;
    public TMP_Dropdown resolutionDropdown;
    public TMP_Dropdown qualityDropdown;
    public Text musicText;
    public Text sfxText;
    public Slider[] audioSliders;
    public Toggle fullScreenToggle;

    private Resolution[] resolutions;

    private void Awake()
    {
        resolutionDropdown.onValueChanged.AddListener(new UnityAction<int>(index =>
        {
            PlayerPrefs.SetInt("resolutionvalue", resolutionDropdown.value);
            PlayerPrefs.Save();

        }));

        qualityDropdown.onValueChanged.AddListener(new UnityAction<int>(index =>
        {
            PlayerPrefs.SetInt("qualityvalue", qualityDropdown.value);
            PlayerPrefs.Save();

        }));

        fullScreenToggle.onValueChanged.AddListener(new UnityAction<bool>(index =>
        {
            PlayerPrefs.SetInt("fullscreen", boolToInt(fullScreenToggle.isOn));
            PlayerPrefs.Save();

        }));
    }

    private void Start()
    {
        qualityDropdown.value = PlayerPrefs.GetInt("qualityvalue");

        var resolutions = Screen.resolutions.Where(resolution => resolution.refreshRate == 60).ToArray();
        resolutionDropdown.ClearOptions();

        List<string> options = new List<string>();

        int currentResolutionIndex = 0;
        for(int i = 0; i < resolutions.Length; i++)
        {
            string option = resolutions[i].width + " x " + resolutions[i].height;
            options.Add(option);

            if(resolutions[i].width == Screen.currentResolution.width &&
                resolutions[i].height == Screen.currentResolution.height)
            {
                currentResolutionIndex = i;
            }
        }

        resolutionDropdown.AddOptions(options);
        resolutionDropdown.value = PlayerPrefs.GetInt("resolutionvalue", currentResolutionIndex);
        resolutionDropdown.RefreshShownValue();

        float musicvolume = PlayerPrefs.GetFloat("musicvolume");
        float sfxvolume = PlayerPrefs.GetFloat("sfxvolume");

        musicText.text = musicvolume.ToString();
        sfxText.text = sfxvolume.ToString();
        audioSliders[0].value = musicvolume / 100f;
        audioSliders[1].value = sfxvolume / 100f;

        fullScreenToggle.isOn = intToBool(PlayerPrefs.GetInt("fullscreen", 0));
        
    }

    public void SetResolution(int resolutionIndex)
    {
        if (resolutions != null)
        {
            Resolution resolution = resolutions[resolutionIndex];
            Screen.SetResolution(resolution.width, resolution.height, Screen.fullScreen);
        }
    }

    public void SetMusicVolume(float volume)
    {
        audioMixer.SetFloat("musicvol", Mathf.Log10(volume) * 20);
        musicText.text = Math.Round(volume * 100, MidpointRounding.AwayFromZero).ToString();

        PlayerPrefs.SetFloat("musicvolume", (float)Math.Round(volume * 100, MidpointRounding.AwayFromZero));
    }

    public void SetSfxVolume(float volume)
    {
        audioMixer.SetFloat("sfxvol", Mathf.Log10(volume) * 20);
        sfxText.text = Math.Round(volume * 100, MidpointRounding.AwayFromZero).ToString();

        PlayerPrefs.SetFloat("sfxvolume", (float)Math.Round(volume * 100, MidpointRounding.AwayFromZero));
    }

    public void SetQuality(int qualityIndex)
    {
        QualitySettings.SetQualityLevel(qualityIndex);
    }

    public void SetFullscreen(bool isFullscreen)
    {
        Screen.fullScreen = isFullscreen;        
    }

    int boolToInt(bool val)
    {
        if (val)
            return 1;
        else
            return 0;
    }

    bool intToBool(int val)
    {
        if (val != 0)
            return true;
        else
            return false;
    }
}

也许我的整个逻辑是错误的，但我想让玩家可以选择更改音乐和 sfx 音量来决定什么是加载器，什么更少。

你可以这样做

[SerializeField] private AudioSource SfxSource;

public void SetSfxVolume(float volume)
{
    audioMixer.SetFloat("sfxvol", Mathf.Log10(volume) * 20);
    sfxText.text = Math.Round(volume * 100, MidpointRounding.AwayFromZero).ToString();

    PlayerPrefs.SetFloat("sfxvolume", (float)Math.Round(volume * 100, MidpointRounding.AwayFromZero));

    if(!SfxSource.isPlaying) SfxSource.Play();
}

或使用 AudioSource.PlayOneShot。

移动滑块时如何播放音频剪辑？
