TOOL DESCRIPTION
OValue Exporter is a userscript that collects empire production data from OGame
and synchronizes it with the OValue web application (ovalue.net), a suite of
calculators for mine production optimization, resource pack planning, and shop
item management.
The script reads data passively as the user navigates standard OGame pages —
no automated page requests, no gameplay interaction. Collected data is stored
locally in Tampermonkey's secure storage and transferred to OValue exclusively
via the browser's localStorage API when the user visits ovalue.net. No data is
ever sent to external servers.
COMPLETE FEATURE LIST
Data Collection:
[+] Mine level extraction per planet (Metal Mine, Crystal Mine, Deuterium Synthesizer)
[+] Planet position and coordinates detection
[+] Planet name extraction from sidebar and empire page
[+] Lifeform type detection per planet (Humans, Rock'tal, Mechas, Kaelesh)
[+] Lifeform-specific building levels (High Energy Smelting / Magma Forge)
[+] Crawler count per planet

Synchronization:

data is transferred to the web app via localStorage and a custom DOM event
[+] Manual export to clipboard (JSON format) for manual import into OValue
[+] Data persistence across sessions using Tampermonkey GM_setValue/GM_getValue
In-page Panel:

API USAGE
Yes, the script uses two OGame endpoints:
Endpoint: /api/serverData.xml
Purpose: Fetch universe name and economy speed
Trigger: Once per page load on Overview, only if not already cached
Endpoint: ?page=standalone&component=empire
Purpose: Read mine levels, planets, crawler counts, active items
Trigger: Only when user manually navigates to the Empire page
Expected request frequency:
- /api/serverData.xml: at most once per Overview page load, skipped if cached
- Empire page: passive read only when user navigates there manually
The script never initiates page navigations or automated requests.
It only reads the DOM of pages the user visits during normal gameplay.
UI MODIFICATIONS
The script makes the following additions to the OGame interface:
1. Navigation menu entry:
A new "OValue" item is appended to the left sidebar navigation (#menuTable),
styled to match the existing menu. Clicking it toggles the data panel.
2. Floating data panel:
A panel positioned to the left of the game sidebar, containing collection
status, officer summary, planet list, and action buttons.
The panel does not overlap or modify any existing OGame UI elements.
No existing OGame interface elements are modified, hidden, or replaced.
