When called in a stage article, gradually crossfades the music to its laststock counterpart if a valid _laststock music file is detected in the /sounds folder. (A valid laststock counterpart to music_loop.ogg would be named music_loop_laststock.ogg, for example.) Both arguments are optional. This function can be used in conjunction with is_laststock() to replicate the music change on the Aethereal Gates stage.

Example 1, called from a stage’s update.gml:

// if everyone has 1 stock remaining, crossfade into laststock music at a rate of 0.01 per frame:
if (is_laststock()) {
music_crossfade();
}

Example 2, called from a stage’s update.gml:

// if everyone has 1 stock remaining, crossfade into laststock music at a rate of 0.025 per frame:
if (is_laststock()) {
music_crossfade( 1, 0.025 );
}

When called in a stage article, gradually decreases or increases the background music to the target volume.

Both arguments are optional; by default the music will fade to silence. Once the music is fully silent, background music playback will be stopped.

Example 1, called from a stage’s update.gml:

// fade to silence at a rate of 0.01 per frame:
music_fade();

Example 2, called from a stage’s update.gml:

// fade to 10% volume at a rate of 0.025 per frame:
music_fade( 0.1, 0.025 );

When called in a stage article, instantly changes the background music volume.

Example, called from a stage’s update.gml:

// instantly set music volume to 50%:
music_set_volume( 0.5 );

When called in a stage article, stops the current background music track.

Example, called from a stage’s update.gml:

// instantly stop music:
music_stop();

When called in a stage article, plays a background music track which replaces the currently playing music track.

Example, called from a stage’s update.gml:

// plays "my_song.ogg" located in the /sounds directory:
music_play_file( "my_song" );
