ActionWML

ActionWML is a summarizing term for all WML actions which can be used in events and some other places.

Types of ActionWML

• direct actions (DirectActionsWML) which have a direct effect on gameplay
• display actions (InterfaceActionsWML) which show something to the user
• internal actions (InternalActionsWML) which are used by WML internally

• conditional actions (ConditionalActionsWML) which contain other actions, which then are executed on certain conditions
• [event] (see EventWML) which creates a new event handler
• [lua] (LuaWML) which contains Lua code to be executed, and
• all tags created from lua with wesnoth.register_wml_action (if they don't fit in one of the categories above)

Where ActionWML can be used

ActionWML can be used

• inside an [event], to define a event handler (see EventWML)
• inside a [then] or [else] of an [if] tag (see ConditionalActionsWML).
• inside a [case] or [else} of a [switch] tag (see ConditionalActionsWML).
• inside the [do] of a [while] tag (see ConditionalActionsWML).
• inside a [command] tag (in [option] or [set_menu_item] or directly as ActionWML) (see InterfaceActionsWML).
• in certain Lua-created tags (if the registered WML action handler interprets the content as ActionWML)
