10) In the next ``HandleMap`` iteration, ``CheckBoardEvent.board`` is called with ``wScriptFlags2[4]`` set.
- If player is not above a tile (``wPlayerTile``) with a space collision: ``wScriptFlags2[4]`` is reset. **Go back to 7**.
- If player is above a tile, the corresponding space script is queued to be executed by ``ScriptEvents`` in the current ``HandleMap`` iteration. ``wScriptFlags2[4]`` is reset. **Continue to 11**.
11) The space script loads the value of ``wCurSpaceNextSpace`` into ``wCurSpace``, loads the new space data to ``wCurSpaceStruct[]``, and decreases ``wSpacesLeft``.
11) The space script loads the value of ``wCurSpaceNextSpace`` into ``wCurSpace``, and loads the new space data to ``wCurSpaceStruct[]``. Unless the space is a Branch Space or a Union Space, ``wSpacesLeft`` is decreased.
- If the space is a Branch Space, the branch data is loaded to ``wTempSpaceBranchStruct``. Then the player is prompted to choose a valid direction. ``wCurSpaceNextSpace`` is populated with the next space that corresponds to the chosen direction. **Go back to 6**.
- If the space is an End Space, a fading out animation plays and then the ``exitoverworld`` script sets ``wMapStatus`` to ``MAPSTATUS_DONE``. This causes ``OverworldLoop`` to return back to the game menu. **Exit this workflow**.
- If ``wSpacesLeft`` is non-0, **go back to 6**.
12) The script code specific to the space type of the landed-on space is executed.
12) If ``wSpacesLeft`` is non-0, **go back to 6**.
13) The script code specific to the space type of the landed-on space is executed.
- If player whites out in battle, ``Script_BattleWhiteout`` executes ``exitoverworld``. **Exit this workflow**.
13) The landed-on space is disabled by executing a block change that converts it into a Grey Space. ``hCurBoardEvent`` is set to ``BOARDEVENT_END_TURN``. ``CheckBoardEvent`` does nothing in this state. In the first subsequent ``HandleMap`` iteration where no other kind of event triggers causing ``PlayerEvents`` to return early, ``hCurBoardEvent`` is set to ``BOARDEVENT_DISPLAY_MENU``.
14) **Go back to 3**
