From 4e59fcf5c1e40dee764317a1190dceadc3a77829 Mon Sep 17 00:00:00 2001 From: Auke Kok Date: Sun, 6 Mar 2016 12:02:21 -0800 Subject: Add consistent monotonic day counter - get_day_count() I've written several experimental bits of code that revolve around the need for a consistent calendar, but implementing one is extremely hard in mods due to time changes and mods overriding core.get_timeofday(), which will conflict. The second part of the problem is that doing this from a mod requires constant maintenance of a settings file. An implementation in core is trivial, however, and solves all of these problems at virtually no cost: No extra branches in server steps, and a single branch when minetest.set_time_of_day(), which is entirely reasonable. We store the day_count value in env_meta.txt. The use case is obvious: This change allows mods to create an actual virtual calendar, or properly account for seasonal changes, etc.. We add a "/days" chatcommand that displays the current day count. No permissions are needed. It can only retrieve the day count, not modify it. --- doc/lua_api.txt | 2 ++ 1 file changed, 2 insertions(+) (limited to 'doc') diff --git a/doc/lua_api.txt b/doc/lua_api.txt index 65af51578..e2ab65ddc 100644 --- a/doc/lua_api.txt +++ b/doc/lua_api.txt @@ -1998,6 +1998,8 @@ and `minetest.auth_reload` call the authetification handler. * `val` is between `0` and `1`; `0` for midnight, `0.5` for midday * `minetest.get_timeofday()` * `minetest.get_gametime()`: returns the time, in seconds, since the world was created +* `minetest.get_day_count()`: returns number days elapsed since world was created, + * accounting for time changes. * `minetest.find_node_near(pos, radius, nodenames)`: returns pos or `nil` * `radius`: using a maximum metric * `nodenames`: e.g. `{"ignore", "group:tree"}` or `"default:dirt"` -- cgit v1.2.3
