-- Can pass in an additional test to allow the walk to action to complete early.
--
-- Example if you have walking to a door, you can end it early if you get to the door, so you don't walk through it
-- meaning you'll always barricade the side of the door you reach first.
-- Example a doorN is on the tile below it, not above it. Walking down the character would walk through the door
-- Then barricade it from below.
