In the war info screen:

  • Easily filter to wars that involved players or PvP wars
  • Drill down into the war to for an overview and list of battles
  • Breakdown casualties and participation per side
  • Easily see when country join or exit a war
  • View stats of battle commanders

This proved quite the challenging feature to implement, as I had been lazy early on when it came to mapping the course of a nation's trajectory through tag switches. See my previous post for a bit more background.

Tracking tag switches is especially important if one wants an accurate war info screen. To illustrate imagine a battle defender:

commander="Leon Tornikes"

See that "BYZ" (Byzantium) is the country. If we wanted to look up the commander (eg: to find his fire pips and such) we need to know which Byzantium to search for. It may seem like an odd notion that there could be multiple Byzantiums, but it's possible. There is a Byzantium at the start of 1444 but they are quickly annexed by the hungry ottomans. Another country could form Byzantium later through tag switching. When this tag switch happens, the initial Byzantium's history (including a history of their generals) is relocated to the latter's original tag.

So I set to work on rewriting the query engine to better follow tag switching, annexations, and releasing of countries.

More Accuracyโ€‹

To visualize this improvement in accuracy let's look at a deficiency in the old version of Rakaly. Below is a true heir of timur run where the player tag switched from Sistan to Delhi and then immediately from Delhi to Mughals. Since Delhi exists at the start, there would be multiple concurrent data points for monthly income even though that shouldn't be possible when playing single player.

This is no longer a problem with the update

Players Viewโ€‹

Sometimes it's nice to have an overview of the multiplayer lobby to answer the following:

  • Who is playing which country
  • Any tag switches that occurred in the game
  • What players have been annexed
  • What players have left the lobby

A player view was added to answer those questions
