Maybe you need 'turn(180)' instead of 'setRotation'.

This would have the actor bounce between two walls, hitting each at the same point every time. You can vary the angle by adding a random turn: 
turn(135+Greenfoot.getRandomNumber(90));
// or
turn(150+Greenfoot.getRandomNumber(60));
You can even have it bounce like a normal bounce by adjusting the direction depending on what wall is being hit (a vertical one or a horizontal one).
