## Footpaths and Navigation
People (in particular via the 'go' action) have an in-built understanding of
footpaths, which are laid out across the map by players, usually using cobble
and cobble steps (but wood can also be used, e.g. for bridges). In addition,
special areas (via the areas mod) are used to 'mark up' routes along these
footpaths. This provides people with the ability to do sensible long-range
navigation as a player would.
Path junctions are marked up by creating a 1x1x1 area above the junction
node. They are always named `path_xxxxx`, where `xxxxx` is the unique name for
that junction - e.g. `path_My House`.
footpaths, which are managed via the footpath mod. This provides people with
the ability to do sensible long-range navigation as a player would.
When following a footpath, preference will always be given to the direction
currently being travelled in. The means that, for example, a cobblestone
footpath can cross a larger area 'paved' with cobblestone (or other footpath
materials), so long as the crossing is in a straight line.
Additionally, above each node leading away from the junction, a 1x1x1 area
with the name `to_xxxxx` is used. In this case, `xxxxx` is the name of the
path node this direction leads to - e.g. `to_Your House`.
Changes to the footpath network only take effect when the `/people footpath_update`
command is used. At this point, if anything is wrong with the network, this
will be indicated, and the previous network will remain in effect. The current
network is saved across server restarts.
If you tell a person to go to a named place (e.g. {"go", name="My House"}) they
will first look for `path_My House`, and then also find the nearest path
junction to where they are now. They will then navigate along the path network
from one to the other.
will first look for a footpath junction with that name, and then also find the
nearest junction to where they are now. They will then navigate along the path
network from one to the other.
If there is no `path_My House` they will also look for just `My House`, and if
that's found, head directly for the centre of that area.
If there is no footpath junction with that name, they'll also look for an area
(areas mod) and head directly for the centre of that area.
