I'm making a game where the player can walk around using the arrow keys, but there are areas I don't want it to be able to walk over, such as lakes, trees, tables, etc

You could set up the unwalkable areas as a separate sprite, and then have the character return to it's last non-touching spot whenever it touches the unwalkable sprite. Something similar to this

Or, alternatively:

when gf clicked
forever
if<key [up arrow v] pressed?>
change y by (2)
if<touching [unwalkable area v]?>
change y by (-2)
end
end
if<key [down arrow v] pressed?>
change y by (-2)
if<touching [unwalkable area v]?>
change y by (2)
end
end
if<key [right arrow v] pressed?>
change x by (2)
if<touching [unwalkable area v]?>
change x by (-2)
end
end
if<key [left arrow v] pressed?>
change x by (-2)
if<touching [unwalkable area v]?>
change x by (2)
end
end

That's a very bad way to do it, as it flips the sprite and involved direction (Am I the only one who dislikes it?)

I dislike it because it prevents all movement rather than solely movement along a single axis. If I move right 1 and down 1, and there is a wall beneath me, I still expect to be moved right by 1. There are ways to accommodate this, but all of them are more complex (or less easily understood) than traditional 2-dimensional movement.
