c# - C#/XNA 在不同的 GameStates 中停止歌曲

Question

我正在尝试在菜单状态下播放音乐，但在切换到游戏状态后会中断。

Answer 1

MediaPlayer 类具有 Play() 和 Stop() 方法。这里是 MSDN 链接：

http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.media.mediaplayer.play.aspx http://msdn.microsoft.com/en-us/library/microsoft.xna.framework .media.mediaplayer.stop.aspx

如果我没记错的话，你可以这样做：

// Variable declaration
Song menu_song;
Song game_song;
bool isInMenu; //I'll use this instead of the gamestate as example

//In the LoadContent method:
//remember to add the song to your project. In this case is in 
//a folder called "music"
 Content.Load<Song>("music/menuSongName"); 
 Content.Load<Song>("music/gameSongName"); 

//In Update method:

if (isInMenu) 
{
MediaPlayer.Stop(); //Stop the current audio...
MediaPlayer.Play(menu_song); //...and start playing the next.
}
else
{
MediaPlayer.Stop(); //Stop the current audio
MediaPlayer.Play(game_song); //...and start playing the next.
}

我没有检查这个代码，如果你有什么问题，请告诉我，我会检查它。=) 游戏状态也是如此，我想你会知道如何根据你的需要调整这段代码。
