Play Background Music in Qt Loop

Question

I want to constantly play background music in a loop until the end of the game.

in the header file:

QMediaPlayer * music = new QMediaPlayer(); 

in cpp file:

  startGame(){ music->setMedia(QUrl("qrc:/sounds/backgroundmusic.mp3")); music->play(); } stopGame(){ music->stop(); } 

Right now, my music plays to the end, but does not restart. How can I make him loop again? Is there a QMediaPlayer member that I can use, or should I run it in a while loop or what?

Answer 1

It looks like you want a QMediaPlaylist . QMediaPlaylist allows you to control the playback mode, in which case you should use Loop . This approach has other benefits, such as CurrentItemInLoop . CurrentItemInLoop will play the current playlist item in a loop, which means that if you add more songs in the future, you can select a song and then create only that track. Thus, for most needs, you only need one playlist. Below is an example of the code, currently I don’t have the tools to test it (Qt multimedia extensions are not installed on this computer). The point should be demonstrated quite well, though.

 QMediaPlaylist *playlist = new QMediaPlaylist(); playlist->addMedia(QUrl("qrc:/sounds/backgroundmusic.mp3")); playlist->setPlaybackMode(QMediaPlaylist::Loop); QMediaPlayer *music = new QMediaPlayer(); music->setPlaylist(playlist); music->play();
