General

A plugin is a Lua script loaded via the command-line option --plugin that runs as a coroutine in parallel with the game UI. Examples of their use in mainline are the host.lua and join.lua scripts which are used during CI to test hosting and joining a game through the multiplayer lobby.

Within the script, data from the game is retrieved via coroutine.yield() which returns three values: events, context, and info:

events, context, info = coroutine.yield()

Events

A table of events the plugin manager has been made aware of, with each event containing the event name in the [1] index and the event data in the [2] index.

Chat

Currently there is only the chat event, which occurs when a chat message or a whisper is sent and contains the following attributes:

  • sender - String. The player sending the message.
  • message - String. The message being sent.
  • whisper - Boolean. Whether the message was sent as a whisper or as a general chat message.

Context

This object contains various functions which can be called to change or set data (mutators). The different contexts available are listed below.

Multiplayer Lobby

Multiplayer Join
