Bridges

The library depends on no other Tilttek package. The bridges under Bridge\ are used only when the application installs the package they bridge to.

Quests

Bridge\Quests\SeasonQuestSchedule is the schedule of a tilttek/quests quest that opens with a season, or with one of its events. Each time the season comes is an occurrence, whose code is the date of the season's first day, so that the quest is accomplished once per year:

use Tilttek\SeasonalEvents\Bridge\Quests\SeasonQuestSchedule;

$schedule = new SeasonQuestSchedule($winter);                              // while the season lasts
$giftWeek = new SeasonQuestSchedule($winter, $winter->event('gift-week')); // while the event runs

Collections

Bridge\Collections\SeasonalItems lists the items of a tilttek/collections catalog that the seasons bring at a moment: each item reference of the kind given, item:snow-hat, names the item of that code; a reference the catalog does not hold is left out.

$items = new SeasonalItems($seasons, $catalogProvider)->at();

A season that comes each year brings its items again: nothing a member collects is gone for good.

An advent calendar during a season

A tilttek/advent-calendar calendar can run in a season without either package knowing the other: the application builds the calendar of each year from the season's next time.

use Tilttek\AdventCalendar\Calendar;

$period = $seasons->next('winter-festival');
$calendar = Calendar::of('advent-'.substr($period->code, 0, 4), 'America/Toronto', $period->code, $surprises);

The calendar's identifier carries the year, so that the openings of one year are not those of the next.
