WorldMgr: Difference between revisions

<!--T:1-->

<!--T:2-->

The '''World Manager''' (WorldMgr) is responsible for managing time, blood moons, climates, weather, fog, wind, lighting, procedural generation of clouds, whether the Lord of the Mountain appears, etc.

== WorldMgr == <!--T:4-->

Sub-managers are created in WorldMgr::init (0x71010F43C0) and inserted into a pointer array (@WorldMgr+0x5c0). All names below are unofficial.

=== Climate === <!--T:6-->

The main WorldMgr class is responsible for keeping climate related parameters and determining which set of climate settings to use. Strangely enough, WorldMgr uses the position of the Camera actor to figure out which map area the player is in (and thus what climate to use), not the Player actor.

<!--T:8-->

Internally, time of day is stored as a float in the [0.0, 360.0] range.

=== TimeMgr::init === <!--T:9-->

=== TimeMgr::reset === <!--T:10-->

* Blood Moon checks are delayed.

* The AnimalMaster_Appearance flag is cleared, meaning the Lord of the Mountain will not appear.

* (If field 0x14A is set to 99, WM_BloodyDay is set to true. [[AIDef:Action/SetBloodyMoonEnv]] uses this to force a Blood Moon to be scheduled. This feature appears to be unused.)

* If both [[Demo]]103_0 and Demo997_0 have not been played, time of day is reset to 78.75 (05:15).

* If [[AIDef:Action/AdvanceTime]] or anything else that changes time of day was called, the actual time is updated at this moment.

<!--T:13-->

* '''Update time of day''': there are several possible update modes. In most cases, the update mode is 0.

* Add (0.0083333 * elapsed frames) to the Time of Day timer. Effectively, this means that 1 in-game minute = 1 real-life second.

* If the timer is >= 360.0, which means that a day has passed, the game subtracts 360 from the timer and then performs midnight checks.

* If FindDungeon_Activated is false (if the player hasn't received the ''The Isolated Plateau'' quest) and if the current time is >= 165.0 (11:00), the time is forcefully set to 11:00. Effectively, this means that time will not get past 11:00 until the Great Plateau Tower is activated and the Old Man cutscene is triggered.

* The Blood Moon timer is updated too.

* If the timer is >= 360.0, which means that a day has passed, the game subtracts 360 from the timer.

'''Note''': In this state, the blood moon timer is never updated and its value is never checked either.

* Update the [[#Day/night time flag]], the [[#Time division, IsMorning, IsNoon, etc.]]

<!--T:23-->

=== Day/night time flag === <!--T:24-->

<!--T:25-->

In any other case, WM_DaytimeFlag is set to true and WM_NighttimeFlag to false.

=== Time division, IsMorning, IsNoon, etc. === <!--T:26-->

Note: all intervals include the start time and exclude the end time.

Otherwise, the game does nothing until the current hour matches the previously generated appearance hour, at which point it sets AnimalMaster_Appearance to true (which allows the LotM to spawn) and goes into state 2.

After one hour has elapsed, the current day of the week is stored and the state is set to 3.

After two week day changes, ''or'' [after the in-game day of the week changes and the current hour is >= the generated appearance hour], the LotM will disappear and the state will be set to 4.

The game waits for the moon type to be 5, before going back to state 0.
