What code have you tried regarding the edge of the world detection, and the bounce?

An actor is at the edge of the world when: - the X co-ordinate is 0 (the left edge of the world) - the Y co-ordinate is 0 (the top edge of the world) - the X co-ordinate is the width of the world minus one (the right edge) - the Y co-ordinate is the height of the world minus one (the bottom edge)

I used this code to make it sort of bounce off the edges but I'm still working on it:

if (getX() <= 15)
{
    setRotation(getRotation() + 80);
}
if (getY() <= 15)
{
    setRotation(getRotation() + 80);
}
if (getX() >= getWorld().getWidth() - 15)
{
    setRotation(getRotation() + 80);
}
if (getY() >= getWorld().getHeight() - 15)
{
    setRotation(getRotation() + 80);
}
You could change the distance by changing the number so it fits the size of of your object. Or you could also change the angle by changing the number in the set rotation method.
