.use(behavior, options = {}) ⇒ Object

Specify that an Entity should behave a certain way.

Different Behaviors will allow you to specify different default values. For example, a Spatiality behavior that allows an Entity to move about the world, may take a default x and y value. The Entity will be placed at that location when the scene is first loaded.

Examples:

A Hero can move about the world.


class Hero < Slickr::Entity
  use Spatiality
end

A Hero starting at a specific location.


class Hero < Slickr::Entity
  use Spatiality, x: 100, y: 100
end

Parameters:

  • behavior (Slickr::Behavior) —

    The behavior to use.

  • options (Hash) (defaults to: {}) —

    Default behavior values.
