i decided to grow plants behind my initial log cabin, and i was a little sad that using it as a big shed would mean walking around to the front every time. So i propose a new mechanic.
-Right click on an unsealed log cabin or other valid structure
-flower menu pops up with some options, "Add Door" being one of them
-Once selected, your cursor can be used to choose which wall to add the door to, with similar previewing as you get for building gates
-more laborious than resource intensive
-structure can be sealed similarly to a cornerpost to prevent anyone from adding an unwanted door and sneaking around
-reduces available space inside the structure where doors are in the way
the possibilities are numerous and exciting
-different kinds of doors? Weak and strong?
-each door with it's own variable materials for extra ugliness?
-possibility for new combinations of wall+structure so long as all the health/soak/whatever values line up?
-cellar doors outside?
-adjacent buildings linking together?
feel free to tell me how it isn't possible and how even if it was it wouldn't work with PvP stuff
