Cocos2dx3.1.1 how to play a sound

1. Load

Cocosdenshion: simpleaudioengine: sharedengine ()-> preloadbackgroundmusic ("music. Mid ");

Cocosdenshion: simpleaudioengine: sharedengine ()-> preloadeffect ("pew-pew-lei.wav ");

These two sentences read the background music files and audio files respectively.

2. Play

Cocosdenshion: simpleaudioengine: sharedengine ()-> playbackgroundmusic ("music. Mid", true );

Cocosdenshion: simpleaudioengine: sharedengine ()-> playeffect ("pew-pew-lei.wav ");

These two sentences are playing music and sound effects respectively.

3. Stop

Cocosdenshion: simpleaudioengine: sharedengine ()-> stopbackgroundmusic (false );

This is to stop playing music.

There are also pause and other related interfaces, but I cannot recover after testing the pause in Win32. I don't know why. You can check the header file of this class by yourself, and there are very few interfaces.

// Pre-load background music
// Cocosdenshion: simpleaudioengine: sharedengine ()-> preloadbackgroundmusic ("kerberhuoworkflow ");
// Play background music
// Cocosdenshion: simpleaudioengine: sharedengine ()-> playbackgroundmusic ("invalid huoworkflow", true );

When the program does not need music, it needs to call simpleaudioengine: sharedengine ()-> end (); release sharedengine ().
