Android game background music audio volume control, android volume control

Game sound effects are the music we use to play games. This is also a must-have for every game. However, if the background music you play is interrupted, we can use getCurrentPosition () this method is used to determine the audio playback offset. In fact, this is also very simple. You only need to set (initialize the sound) and (load the sound resource) in the Code. Other codes are similar to those of the music player, such as starting and stopping. Let's talk about the sound effects in the Code:

[Code] [Java] Code

01 // audio volume

02 intstreamVolume;

03

04 // define the SoundPool object

05 privateSoundPoolsoundPool;

06

07 // define the HASH table

08 privateHashMapsoundPoolMap;

09

10 /************************************** *************************

11 * Function: initSounds ();

12 * Parameters: null

13 * Returns: None.

14 * Description: Initialize the sound system

15 * Notes: none.

16 *************************************** ************************/

17 publicvoidinitSounds (){

18 // initialize the soundPool object. The first parameter is the number of sound streams that can be played simultaneously. The second parameter is the sound type, and the third parameter is the sound quality.

19 soundPool = newSoundPool (100, AudioManager. STREAM_MUSIC, 100 );

20

21 // initialize the HASH table

22 soundPoolMap = newHashMap ();

23

24 // obtain the sound device and device volume

25 AudioManagermgr = (AudioManager) context. getSystemService (Context. AUDIO_SERVICE );

26 streamVolume = mgr. getStreamVolume (AudioManager. STREAM_MUSIC );

27}

28

29 /************************************** *************************

30 * Function: loadSfx ();

31 * Parameters: null

32 * Returns: None.

33 * Description: loads audio resources.

34 * Notes: none.

35 *************************************** ************************/

36 publicvoidloadSfx (intraw, intID ){

37 // load the sound effect in the resource to the specified ID (this ID will be used for playback)

38 soundPoolMap. put (ID, soundPool. load (context, raw, ID ));

39}

40

41 /************************************** *************************

42 * Function: play ();

43 * Parameters: sound: ID of the sound to be played, loop: number of cycles

44 * Returns: None.

45 * Description: playback sound

46 * Notes: none.

47 *************************************** ************************/

48 publicvoidplay (intsound, intuLoop ){

49 soundPool. play (soundPoolMap. get (sound), streamVolume, streamVolume, 1, uLoop, 1f );

How does android add background music and sound effects to the game?

Use Service
 
I recently learned about android game development and helped design a music class, including background music and sound effects. I am a game developed based on the surfaceview framework.

It sounds awesome ..
