public float volume;

Description

The volume of the audio source (0.0 to 1.0).

The AudioSource’s volume property controls the level of sound coming from an AudioClip. The highest volume level is 1 and the lowest is 0 where no sound is heard.

using UnityEngine;

public class Example : MonoBehaviour { AudioSource m_MyAudioSource; //Value from the slider, and it converts to volume level float m_MySliderValue;

void Start() { //Initiate the Slider value to half way m_MySliderValue = 0.5f; //Fetch the AudioSource from the GameObject m_MyAudioSource = GetComponent<AudioSource>(); //Play the AudioClip attached to the AudioSource on startup m_MyAudioSource.Play(); }

void OnGUI() { //Create a horizontal Slider that controls volume levels. Its highest value is 1 and lowest is 0 m_MySliderValue = GUI.HorizontalSlider(new Rect(25, 25, 200, 60), m_MySliderValue, 0.0F, 1.0F); //Makes the volume of the Audio match the Slider value m_MyAudioSource.volume = m_MySliderValue; } }
