GestureDetector.GestureListener

    public boolean touchDown(float x, float y, int point, int button) {

        Vector3 vector3 = new Vector3(x, y, 0);
        getStage().getCamera().unproject(vector3); // 坐标转化
        particlePool.start(KEY_POINT, vector3.x, vector3.y);

actor在整个屏幕中的绝对坐标

            Vector2 leftBottom = actor.localToStageCoordinates(new Vector2(0, 0));
            Vector2 rightTop = actor.localToStageCoordinates(new Vector2(actor.getWidth(),actor.getHeight()));
