Note: Please do let me know of any misbehaviours or desired improvements not already on the list.

The information below is copied from the master README; it may go out of date, so it's better to check the latest version from Github if the below doesn't seem to match. And please, raise an issue or ask a question if you notice the documentation isn't helping enough!

How does it work?

Once the mod is installed, using it is relatively simple:

  • Use the shortcut button "Resource monitor marker" to drag-select at least one ore entity in a patch (like using a blueprint).
    • Can't find the shortcut button? You may need to add it to the shortcut bar.
    • If everything went well, you should now see a blue overlay showing up on top of the ore(s) you clicked, and growing as YARM finds their neighbours, and their neighbours, etc., until the entire ore patch has been scanned.
    • After the scan, you have 2 seconds to select another ore of the same kind, which will be added to the same site.
      • If you tap the ground instead, you will cancel the site creation.
      • If you tap a different kind of ore instead, you will instantly create the site and start a new one on the other ore.
    • Upon the expiry of those 2 seconds, the site will be created and a message will be shown informing you of its name and the amount of ore found in it.
      • Sites can be renamed at any time! The default name is just a suggestion.

By default, YARM shows only sites that are about to expire, i.e. less than X hours runtime remaining. (Estimated through a combination of current speed and lifetime depletion.) In the mod settings this can be tuned. There are buttons available to change the filter to either "no sites" (which never shows any sites at all!) or "all sites" (which never hides them).

Each site has some buttons associated with it:

  • The 'ab|' button allows you to rename the site. This can be useful to prevent auto-naming from overwriting one of your sites with another.
    • Note: Names may not be longer than 50 characters!
  • The 'eye' button opens the map to the center of the ore site.
  • The 'X' button allows you to delete the site. When first clicked, it turns red; click it again within 2 seconds to confirm deletion, or leave it alone to cancel it.
  • The '+' button allows you to expand an existing site. Click the '+' for the site you want to expand, then use the marker tool to select the new ore site you want to add to the existing monitor. Sites are not renamed by this process.
    • NB: For ease of use, the '+' button also activates the resource monitoring marker shortcut.
    • Pressing the '+' while it's red (which indicates addition in progress) will finish the adding process (and update the site, if it's changed).
    • While expanding a site, a blue overlay (identical to the one used when creating the site in the first place) will highlight the ores that comprise the site currently. For performance reasons, the overlay appears gradually rather than all at once.

Sites are bound to forces (i.e., teams), so any sites you add will be visible to your teammates.

Endless resources (by default, oil, but mods exist for others) are supported; they are displayed as "entities x yield percentage" where the yield is an average of all the entities on the site. The depletion indicates how much this average yield goes down per minute. The estimated time indicates when the average yield is expected to hit its minimum value.

Remote interface

YARM's remote interface is grown as needed; there are only a few functions currently:

  • remote.call("YARM", "reset_player", player_name_or_index): sets the target player's character to be whatever the player has selected (if it's of a compatible type, of course) and clears out internal data relative to the player.
    • Note: this is considered deprecated, as the player character is no longer (since v0.8) being changed to allow remote viewing.
  • remote.call("YARM", "reset_ui", player_name_or_index): destroys the target player's YARM UI, forcing it to be recreated (hopefully correctly) at the next UI update cycle (about every 5 seconds).
  • remote.call("YARM", "set_filter", player_name_or_index, new_filter): provides programmatic hooks to change the active filter. The filter value may be 'none', 'warnings', or 'all' -- other values are unsupported. The previously active filter is returned.
  • remote.call("YARM", "get_on_site_updated_event_id"): returns the identifier for the on_site_updated event, detailed below. You should probably call this every time mods are initialized, as it is set in the main control.lua runtime.

Additionally, there is one event:

  • on_site_updated is periodically raised whenever a site's ore count and stats are brought up to date. The event contains:
    • force_name, the name of the force owning this site
    • site_name, the name of the site that just finished updating; site names are unique within a force
    • ore_type, the entity.name of the resource entities tracked in this site (e.g., crude-oil or iron-ore)
    • amount, the number of ore units remaining in the site
    • ore_per_minute, the number of ore units mined in a minute on this site, based on the number mined since the last update
    • remaining_permille, the ratio of ore remaining versus the initial amount from when the site was created
      • NB: permille is analogous to percent, but multiplied by 1000 instead of 100; its symbol is ‰

Visit the Github releases page for manual downloads, if you prefer them. I also would greatly appreciate that bug reports be filed as a new issue for greater visibility (promise you'll get quicker response, too)..
