Overview

Click represents a state of every click in the game. Processable module endows Click with special abilities (the group of “detect” methods). Every object of Click has the scenario parameter, which is an instance of the Lambda. Thereby, an action, which should be performed on click, can be executed lately and lazily (on demand). Scenario is nothing but a bunch of certain actions, being performed on click.

cursor.click = EventHandler::Click.new(mouse_pos, areas)
cursor.click.card #=> Two of Hearts
cursor.click.card.pos  #=> (0, 0)
cursor.click.scenario.call # Perform some action on the card.
cursor.click.card.pos #=> (20, 20)
