Question

我目前正在网上学习游戏开发。我想添加声音fx，让游戏更有趣。程序布局包含MainActivity()和3个主题：GameView()，GameThread()和TheGame()。 TheGame()是所有更新的循环。我创建了一个用于播放声音的新类：

import java.util.HashMap;

import android.content.Context;
import android.media.AudioManager;
import android.media.SoundPool;

public class SoundFX {


public static final int S1 = R.raw.ball;
public static final int S2 = R.raw.balloon;

private static SoundPool mSoundPool;
private static HashMap mSoundMap;

public static void initSounds(Context context){


    mSoundPool = new SoundPool(2, AudioManager.STREAM_MUSIC, 100);
    mSoundMap = new HashMap(2);    // 2 sounds in sound map

    //Put sounds into SoundMap
    mSoundMap.put( S1, mSoundPool.load(context, R.raw.ball, 1) );
    mSoundMap.put( S2, mSoundPool.load(context, R.raw.balloon, 2) );


}//Initiate Sounds

public static void playSound(Context context, int soundID) {
    //No sounds yet loaded..... then Load
    if(mSoundPool == null || mSoundMap == null){

    initSounds(context);

    }

    float volume = 1 ;    // whatever in the range = 0.0 to 1.0

    // play sound with same right and left volume, with a priority of 1,
    // zero repeats (i.e play once), and a playback rate of 1f

    mSoundPool.play(soundID, volume, volume, 1, 0, 1f);

    }//Play


}//SoundFX

但是当我在TheGame循环中检测到碰撞时，我想打电话给班级并播放声音。

我尝试过使用：

SoundFX.playSound(S1);

但Eclipse正在说The Method playSound(Context, int) is not applicable for the argument (int)

有人可以帮忙吗？

Answer 1

您没有传递上下文。

SoundFX.playSound(this, S1);

如何调用单独的类来播放声音？
