Java Andengine输入事件

如何将移动事件添加到精灵中？ 我真的不知道如何使用输入事件，我在这个网站和其他网站上查看了大量不同的链接，没有一个真正起到帮助作用。我需要有人解释并帮助我解决这个问题

}

首先，我将从SimpleBaseAgameActivity扩展。 您需要覆盖精灵对象的OnAreTouch方法。这样：

Sprite sprite = new Sprite(x, y, texture, this.getVertexBufferObjectManager()) {

    public boolean onAreaTouched(org.andengine.input.touch.TouchEvent pSceneTouchEvent, float pTouchAreaLocalX, float pTouchAreaLocalY) 
    {
        //<DO ANYTHING this.setPosition(x,y) method to move the sprite>
        this.setPosition(this.getX() + 10 , this.getY() + 10);
        return true;
    };
};
scene.setTouchAreaBindingOnActionDownEnabled(true);
scene.registerTouchArea(sprite);

看起来你只发布了部分代码示例？很抱歉我会修复它。你的确切意思是什么，你想移动精灵？是的，我想移动精灵
