Stop playing background music in Cocos2d-x

Where can I choose to stop playing background music? For example, in the helloworld scenario, the main code is as follows:

 

[HTML]View plaincopy

1. Bool helloworld: Init ()
2. {
3. Return true;
4. }
6. Void helloworld: onenter ()
7. {
8. Layer: onenter ();
9. Log ("helloworldonenter ");
10. }
12. Voidhelloworld: onentertransitiondidfinish ()
13. {
14. Layer: onentertransitiondidfinish ();
15. Log ("helloworldonentertransitiondidfinish ");
16. }
18. Void helloworld: onexit ()
19. {
20. Layer: onexit ();
21. Log ("helloworldonexit ");
22. // Code ①
23. }
25. Voidhelloworld: onexittransitiondidstart ()
26. {
27. Layer: onexittransitiondidstart ();
28. Log ("helloworldonexittransitiondidstart ");
29. // Code ②
30. }
32. Void helloworld: cleanup ()
33. {
34. Layer: cleanup ();
35. Log ("helloworldcleanup ");
36. // Code ③
37. }

 

In theory, we can stop playing background music with the following code: simpleaudioengine: getinstance ()-> stopbackgroundmusic ("sound/jazzaudio ") place it in three locations (①, ②, and ③ In the code ). Next we will analyze their differences separately.

 

1. Place the code in rows ① and ②.

Put the code in rows ① and ② (that is, in the helloworld: init function). If you call the background music function in a later scenario, the background music is abnormal. We have discussed this issue in the previous section.

 

2. Place the Code in line ③

Put the code in row ③ (that is, in the helloworld: cleanup function). This function is called when the layer object is cleared. It is better to stop playing background music here.
