Constructor & Destructor Documentation

◆ entity_location() [1/4]

game_events::entity_location::entity_location	(	const map_location &	loc,
		std::size_t	id = `0`
	)

Constructor for when an event has a location but not necessarily a unit.

Can also be used if the event has a unit and the caller already has the unit's location and underlying ID.

Definition at line 39 of file entity_location.cpp.

◆ entity_location() [2/4]

game_events::entity_location::entity_location	(	const map_location &	loc,
		std::size_t	id,
		const map_location &	filter_loc
	)

Constructor for when an event has a unit that needs to be filtered as if it was in a different location.

Definition at line 47 of file entity_location.cpp.

◆ entity_location() [3/4]

game_events::entity_location::entity_location ( const unit & u )

explicit

Convenience constructor for when an event has a unit, saving the caller the need to explicitly get the location and underlying ID.

Definition at line 56 of file entity_location.cpp.

◆ entity_location() [4/4]

game_events::entity_location::entity_location	(	const unit &	u,
		const map_location &	filter_loc
	)

Convenience constructor for when an event has a unit that needs to be filtered as if it was in a different location, and the caller does not want to explicitly get the unit's location and underlying ID.

Definition at line 67 of file entity_location.cpp.

◆ matches_unit()

bool game_events::entity_location::matches_unit ( const unit_map::const_iterator & un_it ) const

Determines if un_it matches (using underlying ID) the unit that was supplied when this was constructed.

If no unit was supplied, then all units (including non-existent units) match.

◆ matches_unit_filter()

bool game_events::entity_location::matches_unit_filter	(	const unit_map::const_iterator &	un_it,
		const unit_filter &	filter
	)		const

Determines if un_it matches filter.

If the filter is not empty, the unit is required to additionally match the unit that was supplied when this was constructed.

Member Data Documentation

◆ filter_loc_

map_location game_events::entity_location::filter_loc_

private

This map_location allows a unit to be filtered as if it were somewhere other than where it is.

(Use the parent struct if you want to locate the unit.)

Referenced by filter_loc(), and matches_unit_filter().

◆ id_

std::size_t game_events::entity_location::id_

private

The underlying ID of the unit associated with this.

Set to 0 if there is no associated unit.
