Detailed Description

Domain specific events.

This module defines the game's event mechanism. Events might be units moving or fighting, or when victory or defeat occurs. A scenario's configuration file will define actions to take when certain events occur. This module is responsible for making sure that when the events occur, the actions take place.

Game events have nothing to do with mouse movement, keyboard events, etc. These kinds of system events can be handled using namespace events

WML_HANDLER_FUNCTION() [7/15]

game_events::WML_HANDLER_FUNCTION	(	recall	,
		cfg
	)

If we should recall units that match a certain description.

If you change attributes specific to [recall] (that is, not a Standard Unit Filter) be sure to update data/lua/wml_tag, auto_recall feature for [role] to reflect your changes.

FIXME: we should design the WML to avoid these types of collisions; filters should be named consistently and always have a distinct scope.
