- Addresses within *wCurMapData* ~ *wCurMapDataEnd*: preserved on save. Initialized when entering a level, and updated accordingly throughout the level. Includes:
|
||||
- **wCurTurn**
|
||||
- **wCurSpace**
|
||||
- **wCurLevelCoins**
|
||||
- **wCurLevelExp**
|
||||
- **wCurSpaceStruct**:
|
||||
- **wCurSpaceXCoord**
|
||||
- **wCurSpaceYCoord**
|
||||
- **wCurSpaceEffect** for non-branch spaces, or **wCurSpaceBranchStructPtr** (two bytes) for branch spaces
|
||||
- **wCurSpaceNextSpace** for non-branch spaces
|
||||
|
||||
- Addresses within *wPlayerData* ~ *wPlayerDataEnd*: preserved on save. Includes:
|
||||
- **wUnlockedLevels**: flag array that tracks progression regarding which levels have been unlocked.
|
||||
- **wUnlockedTechniques**: flag array that tracks progression regarding which techniques have been unlocked.
|
||||
|
||||
- These addresses share memory region with string buffers from *wStringBuffer3* onwards. They are placed in memory in the following order.
|
||||
- **wTempSpaceStruct**: Temporary scope. Same structure as *wCurSpaceStruct*
|
||||
- **wTempSpaceBranchStruct**: Temporary scope. The structure is four bytes for next space for each direction (R/L/U/D; -1 if unavailable direction) followed by four bytes for required techniques for each direction (R/L/U/D)
|
||||
- **wViewMapModeRange**, **wViewMapModeDisplacementY**, **wViewMapModeDisplacementX**: Temporary scope during a Vew Map mode session.
|
||||
- **wBeforeViewMapYCoord**, **wBeforeViewMapXCoord**, **wBeforeViewMapMapGroup**, **wBeforeViewMapMapNumber**: Temporary scope during a Vew Map mode session. Used to preserve previous player state.
|
||||
|
||||
- Addresses for talker events:
|
||||
- *wSeenTrainer** addresses have been repurposed as **wSeenTrainerOrTalker***
|
||||
- **wSeenTrainerOrTalkerIsTalker**: added right before *wSeenTrainerOrTalker**.
|
||||
- **wTempTalker** ~ **wTempTalkerEnd**: allocated to the same address space as *wTempTrainer*. Same scope as *wTempTrainer*, but for talker events.
|
||||
|
||||
- Address spaces for backing up the map state (disabled spaces and map objects). Located outside of WRAM banks 0 and 1.
|
||||
- **wDisabledSpacesBackups**: preserved on save to **sDisabledSpacesBackups**.
|
||||
- **wMapObjectsBackups**: preserved on save to **sMapObjectsBackups**.

### Overworld workflow
|
||||
|
||||
1) ``OverworldLoop`` is called from ``GameMenu_WorldMap`` with either ``hMapEntryMethod`` = ``MAPSETUP_ENTERLEVEL`` or ``hMapEntryMethod`` = ``MAPSETUP_CONTINUE``.
