I'm trying to implement a zoom feature but I have a problem. I am zooming in and out a camera with a pinch gesture, I update the camera each time in the render, but my sprites keep their original position and don't change with the zoom in or zoom out.

The Libraries are from libgdx.

What am I missing?

    private void zoomIn()
    {
          ((OrthographicCamera)this.stage.getCamera()).zoom += .01;
    }



public boolean pinch(Vector2 arg0, Vector2 arg1, Vector2 arg2, Vector2 arg3) {
    // TODO Auto-generated method stub

    zoomIn();


    return false;
}

public void render(float arg0) 
{
    this.gl.glClear(GL10.GL_DEPTH_BUFFER_BIT | GL10.GL_COLOR_BUFFER_BIT);
    ((OrthographicCamera)this.stage.getCamera()).update();
    this.stage.draw();


}

public boolean touchDown(int arg0, int arg1, int arg2) {
    this.stage.toStageCoordinates(arg0, arg1, point);


    Actor actor = this.stage.hit(point.x, point.y);


    if(actor instanceof Group)
    {
        ((LevelSelect)((Group) actor).getActors().get(0)).touched();
    }

    return true;

}

Zoom In

Zoom Out
