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 Information here may be outdated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()

- SERVICES:heroTypes()
- SERVICES:spells()
- SERVICES:skills()
- require(URI)

- require("ClassName") - loads additional API and returns it as table (for C++ classes)
- require("core:relative.path.to.module") - loads module from "SCRIPTS/LIB"
- [Todo] require("modName:relative.path.to.module") - loads module from dependent mod
- [Todo] require(":relative.path.to.module") - loads module from same mod
- logError(text) - backup error log function
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)
