WorldMgr

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.
| Subsystem | |
|---|---|
| Official name | Yes |
| Description | Manages world state (time, blood moons, climates, weather, etc.) |
| Init function |
Switch 1.5.0: 00000071010F2920 Wii U 1.5.0: ??? |
| Debug only | No |
Because of the massive amount of state to handle, functionality is split across the main WorldMgr and 9 sub-managers.

Sub-managers
Sub-managers are created in WorldMgr::init (0x71010F43C0) and inserted into a pointer array (@WorldMgr+0x5c0). All names below are unofficial.
| ID | Description |
|---|---|
| 0 | TimeMgr |
| 1 | CloudPr? Handles cloud procedural generation. |
| 2 | ??? |
| 3 | Weather? Handles "rain splash" and climate weathers. |
| 4 | TemperatureMgr? (Reasonably sure about this one.) |
| 5 | ??? |
| 6 | Sky and fog? Holds the configuration for all EnvPalettes, EnvAttributes, WeatherInfluences, Remains palettes, Indoor palettes and dungeon fogs. |
| 7 | DofMgr? Holds depth of field related parameters. |
| 8 | ??? (contains a BaseProcLink, so it might have something to do with actors.) |
TimeMgr
TimeMgr handles everything to do with time, including Blood Moons and the Lord of the Mountain's apparition.
Internally, time of day is stored as a float in the [0.0, 360.0] range.
TimeMgr::init
- Time is set to 78.75 (05:15).
- Time for TotS environment is set to 78.75 (05:15) as well.
- "Bloody Moon end reserve timer" is set to 0.
TimeMgr::reset
This is called whenever a stage is unloaded (essentially every time the loading screen is shown).
- Blood Moon checks are delayed.
- The AnimalMaster_Appearance flag is cleared, meaning the Lord of the Mountain will not appear.
TimeMgr::calc
This is called every frame.
- Reload some internal state from GameDataMgr.
- If both Demo103_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.
- Blood Moon checks.
- Update time of day.
- 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.
- Update Blood Moon timer.
- Update Daytime, Night time, is morning, is noon, is evening flags (see below).
- Update time division (see below).
- Update "Bloody moon end reserve timer".
- Decrement the reserve timer. If the new timer value is zero or negative, the WM_BloodyDay flag is cleared.
- Update GameDataMgr state (time, number of days, Blood Moon timers).
- Update Lord of the Mountain flags (in particular, determine if it should appear).
Blood Moon
Day/night time flag
From 00:00 to 06:00 (closed interval) and from 18:00 to 00:00 (closed interval), WM_DaytimeFlag is set to false and WM_NighttimeFlag is true.
In any other case, WM_DaytimeFlag is set to true and WM_NighttimeFlag to false.
