Instance Method Details

#define_actor(name, &blk) ⇒ Object

Defines an actor type, (ie :plumber). Optionally adding attributes, behaviors and a view.

Raises an erorr if the actor already exists

define_actor :plumber do
  # define default attributes and values
  has_attribute(s) x: 7, y: 12

  # define default behaviors and their options options can be
  #   - list of behavior names
  #   - hash of behavior names to options for each behavior
  #   - block form
  has_behavior :postitioned
  has_behaviors do
    jumper max: 12, double: true
  end

  # Allows the inlining of one behavior in this actor.
  # It is equivalent to creating a behavior with the same name as the actor,
  # and adding it to the actor.
  #
  # The block works the same as calling #define_behavior.
  behavior

  # Allows the inline of a view in this actor
  # It is equivalent to creating an actor view with the same name as the actor.
  # 
  # The block works the same as calling #define_actor_view.
  view

end

#define_actor_view(name, &blk) ⇒ Object

Defines an actor view type. (ie :plumber_view). Constructed when any actor with matching name is created ie: :ship_view will be created and shown for any actor :ship that is created

Raises an erorr if the actor view already exists

define_actor :plumber_view do
  # injects your dependencies; will construct if needed
  requires :input_manager, :customer_monkey_factory

  # callback when your view is created
  # #actor will be available at this time
  setup &block

  # define any helper methods and include any needed modules
  helpers &block

#define_behavior(name, &blk) ⇒ Object

Defines a behavior type. (ie :jumper or :shooter)

Raises an erorr if the behavior already exists

define_behavior :jumper do
  # injects your dependencies; will construct if needed
  requires :input_manager, :timer_manager, :stage

  # adds the required behaviors to your actor if not present
  # NOTE: no options can be passed to the added behavior
  required_behaviors :positioned

  # callback when your behavior has been added to an actor
  # #opts will be populated with any args that were specified on behavior
  # addition 
  setup &block

  # callback when your behavior has been removed from an actor
  remove &block

  # define a custom handler for reacting to your actor's messages
  # @see Behavior#reacts_with for recommended message dispatch
  react_to &block

  # define any helper methods and include any needed modules
  helpers &block
