How do you remove two Actors in one Actor like:

        if(Greenfoot.mouseClicked(this))
        {
         getWorld().addObject ( new Ground2(), 402, 748);
         getWorld().addObject ( new Ground2(), 850, 748);
         getWorld().addObject ( new Ground(), 450, 433);
         getWorld().addObject ( new SubGround(), 250, 550);
         getWorld().addObject ( new DHealthbar(), 1400, 748);
         getWorld().addObject ( new Bowman(), 89, 608);
         getWorld().addObject ( new Dragonoir(), 1500, 370);
         getWorld().setBackground("BATTLE.png");
         getWorld().removeObject(this);                            
 }

then you also getWorld().removeObject("Random.class); but, when I do that, it give me an error saying it can't be applied.

It can't be applied because the arguments to removeObject() need to be an Actor, not a class. In the place of Random.class, put the reference to the object you wan't to remove. Also make sure to do this before you remove yourself, or else you will not be able to access the world.

What builderboy2005 said, and also there is an opening " mark before Random.class, but not one after

How do you make a reference? I'm sorry, I am still new to java.

you need removeObjects(); use this code:

getWorld().removeObjects(getWorld.getObjects(Random.class));

Reference:

protected void addedToWorld(World world)
{
    this.world = world;
}

says that" world is not public in greenfoot.Actor; cannot be accessed by outside package"

You really do not need the 'Reference' part, just the first line of code kiarocks supplied. But what he meant was:

getWorld().removeObjects(getWorld().getObjects(Random.class));

He missed the '()' after the second 'getWorld' (just an oversite, I'm sure).
