如何使粒子系统可点击

Question

我正在研究一个游戏项目，并想知道如何设置SpriteParticleSystem上的点击事件，因为我已将粒子数设置为1。

如何让这个粒子可点击？

{ 
    // B1= new ButtonSprite(8, 12, this.mParticleTextureRegion, this.getVertexBufferObjectManager()); 

    final SpriteParticleSystem particleSystem1 = new SpriteParticleSystem(new PointParticleEmitter(GameActivity.CAMERA_WIDTH - 200, GameActivity.CAMERA_HEIGHT), 8, 12, 1, this.player, this.getVertexBufferObjectManager()); 

    particleSystem1.addParticleInitializer(new VelocityParticleInitializer<Sprite>(-15, -22, -70, -90)); 
    particleSystem1.addParticleInitializer(new AccelerationParticleInitializer<Sprite>(0, 15)); 
    particleSystem1.addParticleInitializer(new RotationParticleInitializer<Sprite>(0.0f, 360.0f)); 

    particleSystem1.addParticleInitializer(new ExpireParticleInitializer<Sprite>(11.5f)); 


    particleSystem1.addParticleModifier(new AlphaParticleModifier<Sprite>(2.5f, 3.5f, 1.0f, 0.0f)); 
    particleSystem1.addParticleModifier(new AlphaParticleModifier<Sprite>(3.5f, 4.5f, 0.0f, 1.0f)); 

    particleSystem1.addParticleModifier(new AlphaParticleModifier<Sprite>(4.5f, 11.5f, 1.0f, 0.0f)); 


    scene.attachChild(particleSystem1); 
} 
/* Left to right Particle System. */ 
{ 
    particleSystem2 = new SpriteParticleSystem(new PointParticleEmitter(200, GameActivity.CAMERA_HEIGHT), 6, 30000, 1, this.mParticleTextureRegion, this.getVertexBufferObjectManager()); 
    //particleSystem2.addParticleInitializer(new BlendFunctionParticleInitializer<Sprite>(GLES20.GL_SRC_ALPHA, GLES20.GL_ONE)); 
    particleSystem2.addParticleInitializer(new VelocityParticleInitializer<Sprite>(15, 22, -60, -90)); 
    particleSystem2.addParticleInitializer(new AccelerationParticleInitializer<Sprite>(-1, 15)); 
    particleSystem2.addParticleInitializer(new RotationParticleInitializer<Sprite>(0.0f, 360.0f)); 
    //particleSystem2.addParticleInitializer(new ColorParticleInitializer<Sprite>(1.0f, 0.0f, 0.0f)); 
    particleSystem2.addParticleInitializer(new ExpireParticleInitializer<Sprite>(11.5f)); 

    //particleSystem.addParticleModifier(new ScaleParticleModifier<Sprite>(0, 5, 0.5f, 2.0f)); 
    particleSystem2.addParticleModifier(new AlphaParticleModifier<Sprite>(2.5f, 3.5f, 1.0f, 0.0f)); 
    particleSystem2.addParticleModifier(new AlphaParticleModifier<Sprite>(3.5f, 4.5f, 0.0f, 1.0f)); 
    //particleSystem.addParticleModifier(new ColorParticleModifier<Sprite>(0.0f, 11.5f, 1.0f, 0.0f, 0.0f, 0.0f, 0.0f, 1.0f)); 
    particleSystem2.addParticleModifier(new AlphaParticleModifier<Sprite>(4.5f, 11.5f, 1.0f, 0.0f)); 

    scene.attachChild(particleSystem2); 
}

我不是100％肯定，如果它会工作，但试试这个：初始化粒子系统后

final IParticleInitializer iPartInit = new IParticleInitializer() { 

     @Override 
     public void onInitializeParticle(Particle pParticle) { 
      Particle temp = new Particle(pParticle.getX(), pParticle.getY(), pParticle.getTextureRegion()) //make a temporary particle that you can override the onTouchArea of 
      { 
       @Override 
       public boolean onAreaTouched(TouchEvent pSceneTouchEvent, 
         float pTouchAreaLocalX, float pTouchAreaLocalY) { 
        int eventaction = pSceneTouchEvent.getAction(); 
        switch (eventaction) { 
        case TouchEvent.ACTION_DOWN: 
         //do whatever you want 
         break; 
        } 
        return true; 
       } 
      }; 
      pParticle = temp; 
     } 

particleSystem1.addParticleInitializer(iPartInit); 

用这个吧。
