Module:MapObjectsData
From Heroes of Might and Magic: Olden Era Official Wiki
Description
The BuildingsData module provides a centralized interface to retrieve adventure map object data from the MapObject Cargo table and their localized strings from the Translation Cargo table.
It is designed to be "page-aware," meaning it can automatically identify the correct object ID and language based on the current page title (e.g., handling subpages and language suffixes).
Syntax
{{#invoke:BuildingsData|get|id=|field=|language=}}
Parameters
id(optional): The unique object ID (e.g.,barracks_unfrozen_6) or english building name (e.g.,Bloated Mansion). If omitted, the module attempts to detect it from the current page title.field(required): The specific data field to retrieve.language(optional): The language code (e.g.,fr,de). If omitted, the module attempts to detect it from the page title suffix (e.g.,/fr).
Available Fields
Localization (from Translation table)
name,description(using typemap_object)narrative(using typemap_object_narrative)
Technical (from MapObject table)
category,goods_value,ai_value,custom_guard_value,view_radius,guard_units,fraction,tier,resource_name,resource_value,source_path
Examples
Automatic Mode
If you are currently viewing the page Bloated Mansion/fr, the module automatically identifies the object and the language:
{{#invoke:BuildingsData|get|field=name}}
- Result: Lua error at line 36: attempt to call global 'queryCargo' (a nil value).
{{#invoke:BuildingsData|get|field=narrative}}
- Result: Lua error at line 42: attempt to call global 'queryCargo' (a nil value).
Manual Mode
To fetch specific data regardless of the current page:
{{#invoke:BuildingsData|get|id=barracks_unfrozen_6|field=tier}}
- Result: Lua error at line 50: attempt to call global 'queryCargo' (a nil value).
Technical Notes
- ID Detection: The module cleans the page title by removing subpages (text after
/) and parenthetical text to match the entity name in the database. - Fallback: If a
namerequest returns no data, the system relies on the object'scategoryfield for identification.
