How to understand that the game is out?

Question

Unity

Greetings, I have a system: if music plays in the game (musicPlaying == 1, the object on which the script is DontDestroyOnLoad), went to another level, returned to the menu, the music does not start from the beginning (continues to play). But if, to exit the game, the value will be that the music is playing (but not actually playing), and will not let the music start ("Well, it's playing, but it's worth it").
Game for Android. It will not work to "hang" 0 on the exit button, because. often in mobile games, the player himself "throws out" the application from the processes, and on a PC you can do this.

Answer 1

OnApplicationPause() is called when the player selects another application or closes the game
