音频源的音量(0.0 到 1.0)。
AudioSource 的音量属性控制来自 AudioClip 的声音级别。最高音量等级为 1,最低音量为 0(此时听不到声音)。
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; } }
