Hi, I'm trying to create a world where the object moves and when it hits the edge it bounces back into the opposite direction. I figured out how to make it move to the other side but not how to bounce it off. Here's my code so far-

  public void act()
    {
        move(+12);
        if(getX() == (getWorld().getWidth()-1))
        {
           setLocation(0, getY());
        }
        else if(getX() == 0)
        {
           setLocation(getWorld().getWidth(), getY());
        }     
       
        if(getY() == (getWorld().getHeight()-1))
        {
           setLocation(getX(), 0);
        }
        else if(getY() == 0)
        {
           setLocation(getX(), getWorld().getHeight()); 
        }
    }   
}

To bounce, you need to adjust the rotation of the object instead of its location.
