# This is a convenience trait.
#
# Instead of calling
# @controls << Control.new(self, @player1, :some_key_code => :action)
# you can define the controls in the object itself.
#
module Controllable extend Trait

end
module ClassMethods
# Enables to define the controls in the object itself, as in the Example:
#
# class Spaceship < Thing
# it_is Controllable
# controls Gosu::Button::KbA => Turnable::Left,
# Gosu::Button::KbD => Turnable::Right,
# Gosu::Button::KbW => Moveable::Accelerate,
# Gosu::Button::KbS => Moveable::Backwards,
# Gosu::Button::KbSpace => Shooter::Shoot
#
def controls mapping
attr_accessor :controls_mapping
InitializerHooks.register self do
self.controls_mapping = mapping
self.controls
end
end
end
# You can add controls dynamically.
#
# Provide a hash of mappings:
# player_one.controls Gosu::Button::KbA => Turnable::Left,
# Gosu::Button::KbD => Turnable::Right
#
def controls mapping = nil
self.window.add_controls_for self, mapping
