Discussion My simplistic non-linear master volume slider

This is said to be the "right way"

It seems to involve setting all of the AudioSources to an AudioMixer. The slider is set from 0.0001 to 1 (0 is a problem).

In the mixer it goes from -80 to 20 on a logarithmic scale....

Their code:

Code (CSharp):

1. public void SetLevel(float sliderValue)
2. {
3.     mixer.SetFloat("MusicVol", Mathf.Log10(sliderValue) * 20);
4. }

My code:

Code (CSharp):

1.     void Start()
2.     {
3.         SetVolume(PlayerPrefs.GetFloat("masterVolume", 1f));
4.     }
5.  
6.     public void SetVolume(float volume)
7.     {
8.         volumeSlider.value = volume;
9.         float adjustedVolume = Mathf.Pow(volume, 2f); // square the value (power of 2)
10.         AudioListener.volume = adjustedVolume;
11.         soundVolumeText.text = (adjustedVolume * 100).ToString("0") + "%";
12.         PlayerPrefs.SetFloat("masterVolume", volume);
13.     }

My slider goes from 0 to 2 with a default of 1. The text goes from 0% to 400%.

AudioListener.volume is the global volume - no need to set up any mixer.

You can make a reset button that calls SetVolume with a parameter of 1.
