persistent_monoids
player_monoids that persist between player sessions and server restarts/crashes. see https://content.minetest.net/packages/Byakuren/player_monoids/ for more information.
API
the API is almost identical to player_monoids, w/ a couple changes
local my_monoid = persistent_monoids.make_monoid("my_monoid", { -- a unique name for the monoid is obligatory
... -- definition as in a regular player_monoid
})
my_monoid:add_change(player, value, "some_id") -- unlike player_monoids, an ID is obligatory
