One ： Preface

I haven't used this mixer tool for many years , After all, many functions are controlled by writing their own code as much as possible , In this way, it will be easy to maintain and modify later , Recently, some students are consulting the sound management system , Especially how to use this mixer . I took advantage of this opportunity to get to know and learn , Record here . Here we only record the unified control properties of the mixer , Other audio resource management modules are not involved here , There will be time to record separately .

Two ： Control logic

Our commonly used game audio types are mainly divided into three categories ：1.Music The background music （ There has always been ）2. Instantaneous sound effect （ Instant generation ）3. Plot dubbing （ It can also be classified as sound effect ）. When using code management to control these sound effects , Especially the management setting of sound volume , All of them are classified management first, then all of them are traversed, and then the volume is set , Although it is troublesome, its advantage is that it is convenient for us to maintain and modify , The other is to separate the volume control logic or other attribute control and give it to the mixer for processing. In fact, it is also very convenient . My idea here is to create three mixers, one overall Mixer, One MusicMixer And a SoundEffectMixer, Among them, the overall situation is only right MusicMixer and SoundEffectMixer Conduct management , Then the specific sounds are attributed to SoundEffectMixer and MusicMixer management . In simple words, you can also make one directly Mixer Manage music directly

3、 ... and ： Make mixer Mixer

Right click to create mixer , Change the name to MasterMixer.., The other two can be clicked Mixers The following plus sign can also be created by right clicking on the outside .

 2. Set parent-child relationship

 3. Set the corresponding AudioSource

Select the music in the scene respectively , And then put the right MasterMixer Drag the corresponding type into the music Output In the trough

 4. Burst attribute

1. Choose Mastermixer,2. Then select the target Mixer 3. Find the right Volume attribute 4. stay Volume Right click on the top to reveal the attribute 5. Modify the attribute name f2

Three Mixer It will leak out  

Four ： Edit code control

public class Test : MonoBehaviour
{
    public AudioMixer audioMixer;//MasterMixer
    public AudioSource soundClick;//sound
    public void SetAllVolume(Slider s)
    {
        audioMixer.SetFloat("MasterVolume", s.value);
    }
    public void SetMusicVolume(Slider s)
    {
        audioMixer.SetFloat("MusicVolume", s.value);
    }
    public void SetEffectVolume(Slider s)
    {
        audioMixer.SetFloat("EffectVolume", s.value);
    }
    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.P))
        {
            soundClick.Play();
        }
    }
}

  5、 ... and ：Slider Slider settings

1. Set according to the maximum and minimum volume in the mixer slider The maximum and minimum value of [-40,0]

2. Add event
