How can I remove an actor at a certain place?

Get a reference to the actor with the 'getObjectsAt' method and then remove it.

Like this?

getWorld().removeObject(getWorld().getObjectsAt(10, 10, x.class));

Almost. The getObjectsAt method returns a list of objects and not just one object.

So, is it wrong? How can it return only one object?

if (!getWorld().getObjectsAt(10, 10, x.class).isEmpty())
{
    getWorld.removeObject(getWorld().getObjectsAt(10, 10, x.class).get(0));
}

One more question, what is this for?

.get(0))

It gets the first element in the list.
