Help Stopping Music

The post quoted here was an attempt to have you show what you used, code-wise, to create and start the music to begin with. Without knowledge of this, it would be almost impossible to help in the matter. However, I can say that you should not declare a new field for the sound in the actor class. That just creates a NEW sound object (which is not the one that is playing). Stopping it does not stop the one playing.

public void stopped() { backgroundMusic.playLoop(); GreenfootSound gameover = new GreenfootSound("gameover.mp3"); if (gameover.isPlaying()) { backgroundMusic.stop(); } } I created this method in my world class. backgroundMusic is in the first line as a world instance variable and I want the backgroundMusic to play until the other music starts.

First, please use code tags when you post code: Now, in the code you posted you are creating a new sound and then immediately checking if it is playing: The condition can never be true. You only just created the sound object, so there is no way it can be playing. You need to use the same sound object that you initially started playing, and check if that object is still playing. You cannot create a new sound object and check if that one is playing. As a first step you need to change: Into code which plays a GreenfootSound object which you maintain a reference to (so that you can check later whether it is still playing).
