Default aliases for the 10 canonical cardinal directions
(NavigationApi.cardinalDirections()) plus their conventional
single/double-letter abbreviations. Every entry expands to
go <full-name>, which dispatches through GoController and
resolves the actor's currently-engaged locomotion mode at run
time — so n does the right thing whether the actor is
walking, swimming, or climbing.
Composed onto any host that also composes AliasMixin (the
collector walks the mixin chain). Hosts without alias support
pay no cost. Player-set aliases on the same name win.
The cockpit's <exit> click emits the full go <dir> form
for pedagogy; these aliases give keyboard users the short
forms they expect from MUD muscle memory.
Movement-message templates. Schema-defaulted; player-overridable
via the settings command on Avatars (which compose
EnvironmentMixin); NPCs render at the schema default through
resolveSetting's non-Environment fallback. Liquid syntax —
see docs/subsystems/prose.md.
Commands the mover itself supplies — locomotion and door interaction. Anything with MobileMixin (Avatar today; NPCs, vehicles in future) automatically gains
go,open, andclose.
