JAVA游戏编程之三----j2me 手机游戏入门开发--俄罗斯方块_4_增加消除行声音

 

之前的游戏代码中都未加声音，不少网友在做别业设计时要求增加声音，其实声音还是比较好做的！但手机真机上可能会有不同的问题，但在模拟器上一般都没什么问题，所以真机上的问题就具体问题具体分析吧！这里给出一个很简单的声音应用。

在原 俄罗斯方块_3的代码基础上增加一个声音类！

示例代码如下

---

 package code; import java.io.*; import javax.microedition.media.Manager; import javax.microedition.media.MediaException; import javax.microedition.media.Player; public class Sound { public static Player m_sounds; public static int m_currentSoundID = -1; public static boolean s_sound_bg_On = false; private static final String SOUND_FILENAME ="/pics/newmsg.wav"; //0.背景声音 public static final void initSound() { if( m_sounds != null ) return; try { DataInputStream dis= new DataInputStream("".getClass().getResourceAsStream(SOUND_FILENAME)); byte[] soundBuffer = new byte[dis.available()]; dis.read( soundBuffer ); InputStream is = new ByteArrayInputStream(soundBuffer); m_sounds = Manager.createPlayer(is, "audio/x-wav" ); m_sounds.realize(); m_sounds.prefetch(); }catch( Exception e ) { e.printStackTrace(); } } public static void playSound( int soundID ) { playSound( soundID, 1 ); } public static void playSound( int soundID, int loopCount ) { try { if( m_sounds == null ) return; if( m_sounds.getState() == javax.microedition.media.Player.STARTED ) return; m_currentSoundID = soundID; m_sounds.setMediaTime( 0 ); m_sounds.setLoopCount( loopCount ); m_sounds.start(); Thread.sleep( 50 ); // maybe this can help for sound problems }catch( Exception e ) { e.printStackTrace(); } } private static void stopSound() throws Exception { try { if( m_sounds == null ) return; if( m_sounds.getState() == javax.microedition.media.Player.STARTED ) m_sounds.stop(); if( m_sounds.getState() == javax.microedition.media.Player.PREFETCHED ) m_sounds.deallocate(); m_currentSoundID = -1; }catch( Exception e ) { e.printStackTrace(); } } public static int readFileToMemory( String fileName, byte[] buffer ) { java.io.InputStream file = null; int size; try { file = fileName.getClass().getResourceAsStream( fileName ); size = file.read( buffer ); file.close(); file = null; }catch( Exception e ) { return -1; } return size; } }

 

现在优快云上贴代码不如以前的好了！：（

 

使用方法 是在主Canvas类的初始化或者游戏初始化的地方调用 Sound类的initSound()方法，来初始化声音文件，

然后在想要播放的地方调用Sound类的playSound()方法，目前这个简单的例子里只有一个声音，所以参数给啥都一样，如果以后声音多了！就可以用这个参数来区分用户要调用的是那个声音了！这里的用户是相对这个Sound类的使用者，就是程序员，Sound类都是静态方法，这里相对于一个公共的工具类！

 

如果上述使用方法您没看明白，那就看一下代码

主Canvas类代码如下
