Non accessible variable

I have tried to make a certain variable change, but i am having trouble accessing it. Here is the code: 
Actor a = getOneObjectAtOffset(535,45,Actor.class);
        if(a != null)
            a.stop(stop);

You do realize that 'getOneObjectAtOffset(535,45,Actor.class);' will return an Actor that is at the location (this.getX() + 535, this.getY() + 45), if one exists there. Maybe you meant 'getOneObjectAtOffset(535 - getX(), 45 - getY(), Actor.class);' returning an Actor at the absolute location (535, 45), if one exists there.

new code:
List b = getWorld().getObjectsAt(535,45,Button.class);  
        if(b != null)  
            b.stop(stop);

That should work also; I did not want to go with to 'List' option. But you might have to use '(b.get(0)).stop(stop);', since b is now a 'List' of 'Button's.

reverted to this:
Actor b = getOneObjectAtOffset(535 - getX(),45 - getY(),Button.class);  
        if(b != null)  
            b.stop(stop); // this is highlited
and got this
cannot find symbol - method stop(boolean)

You declare 'b' to be an 'Actor': Actor b = ... So when you call "b.stop(...)" the compiler looks in the Actor class for the method. There is no such method in the Actor class, so you get an error. You need to declare 'b' to be a 'Button', and use a typecast: 
Button b = (Button) getOneObjectAtOffset(535 - getX(),45 - getY(),Button.class);  
        if(b != null)  
            b.stop(stop);

ok, that works, but why doesn't this code? 
if(Greenfoot.mouseClicked(this) && ((b2 && firsttime) || (b2 && SpaceShips.gotremoved)))
        {
            getWorld().addObject(new SpaceShips(),599,220);
            firsttime = false;
        }
        else if(Greenfoot.mouseClicked(this) && getWorld() instanceof CircutWorld)
        {

            Greenfoot.setWorld(new SpaceWorld(true));
            SpaceShips.stop = false;
        }
        else if(Greenfoot.mouseClicked(this) && stop && !b2)
        {

            Greenfoot.setWorld(new CircutWorld());
        }

i repositioned the b.stop(stop); to a different location and it fixed it.

Try this: 
if (Greenfoot.mouseClicked(this))
{
    if (b2 && (firsttime || SpaceShips(gotremoved)))
    {
        getWorld().addObject(new SpaceShips(), 599, 220);
        firsttime = false;
    }
    else if (getWorld() instanceOf CircutWorld)
    {
        Greenfoot.setWorld(new SpaceWorld(true));
        SpaceShips.stop = false;
    }
    else if (stop && !b2)
    {
        Greenfoot.setWorld(new Circutworld());
    }
}
