问统一，我如何暂停音频的水平？

EN

#pragma strict

var pausemenu: GameObject;

public function pause() 
{
    pausemenu.SetActive(true);
    Time.timeScale = 0;

}

public function Resume () 
{
    pausemenu.SetActive(false);
    Time.timeScale = 1;
}

public function Restart ()
{
    Application.LoadLevel("IntroScene");
    Time.timeScale = 1;
}

public function MainMenu ()
{
    Application.LoadLevel("string");
}

public function Quit ()
{
    Application.Quit();
}
