API Reference

[Todo] In near future Lua API may change drastically several times. Information here may be outdated

Globals

  • DATA - persistent table
    • DATA.ERM contains ERM state, anything else is free to use.
  • GAME - IGameInfoCallback API
  • BATTLE - IBattleInfoCallback API
  • EVENT_BUS - opaque handle, for use with events API
  • SERVICES - root "raw" access to all static game objects
    • SERVICES:artifacts()
    • SERVICES:creatures()

Low level events API

-- Each event type must be loaded first
local PlayerGotTurn = require("events.PlayerGotTurn")

-- in this example subscription handles made global, do so if there is no better place
-- !!! do not store them in local variables
sub1 = 	PlayerGotTurn.subscribeAfter(EVENT_BUS, function(event)
		--do smth
	end)

sub2 = 	PlayerGotTurn.subscribeBefore(EVENT_BUS, function(event)
		--do smth
	end)
