Question

您好我正在使用Andengine制作游戏应用程序

因为我想在点击该精灵时更改精灵的背景图像。任何人都可以帮助我如何做到这一点。

this.mFaceTextureRegionBackOn = TextureRegionFactory.extractFromTexture(this.mTextureBackOn);
this.mFaceTextureRegionBackOff = TextureRegionFactory.extractFromTexture(this.mTextureBackOff);

final ButtonSprite back = new ButtonSprite(centerXBack, centerYBack, this.mFaceTextureRegionBackOn, this.getVertexBufferObjectManager());
scene.attachChild(back);
back.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(ButtonSprite arg0, float arg1, float arg2) {
        MainActivity.this.mFaceTextureRegionBackOn = TextureRegionFactory.extractFromTexture(MainActivity.this.mTextureBackOff);
    }
});

当我点击该按钮时有一个精灵按钮它的纹理区域我正在改变，但它无法帮助我改变该精灵的图像

AndEngineExamples中有类似的用法，请参阅https://github.com/nicolasgramlich/AndEngineExamples/blob/GLES2/src/org/andengine/examples/UpdateTextureExample.java

为什么你不能只创造两个精灵并切换他们的可见度？我以这种方式在\ off按钮上切换声音：

soundOnBtn = new Sprite(TILE_SIZE/2, 0, TILE_SIZE, TILE_SIZE, gameResources.getSoundOnTR())
    {
        @Override
        public boolean onAreaTouched(TouchEvent pSceneTouchEvent, float pTouchAreaLocalX, float pTouchAreaLocalY)
        {
            soundOn = !soundOn;
            soundOnBtn.setVisible(soundOn);
            soundOffBtn.setVisible(!soundOn);
            return true;
        }
    };
    mainScene.registerTouchArea(soundOnBtn);
    soundOffBtn = new Sprite(TILE_SIZE/2, 0, TILE_SIZE, TILE_SIZE, gameResources.getSoundOffTR());
    soundOffBtn.setVisible(false);
    bottomPanelLayer.attachChild(soundOnBtn);       
    bottomPanelLayer.attachChild(soundOffBtn);

更改sprite andengine的图像
