I was given an amazing amount of info before, yet I still cant get the program to work :( 
 public void act()
    {
        if (Greenfoot.mouseClicked(null)) {    
            List all = getObjects(MyActor.class);    
            MyActor a = (MyActor) all.get(Greenfoot.getRandomNumber(all.size()));    
            a.getImage().setTransparency(255);    
        }  
    }

Please supply the error message you are getting (copy/paste into your post). I have a feeling (though I cannot be sure) that it may be that there are no 'MyActor' objects in the world and you are getting an IllegalArgumentException' error when trying to 'get' a non-existant element from the existing list. BTW, the list will ALWAYS exist; it just might be empty of elements.
