-- In addition, the NPCs need to know where some places are, and know

-- where there are nodes they can use. For example, they need to know where the

|
|
-- to know where the farm they work is located, or where the bed they sleep is.
|
|
-- Other mods have to be supported for this to work correctly, as there are
|
|
-- many sitting nodes, many beds, many tables, chests, etc. For now, by default,

-- support for default and cottages is going to be provided.
