Draco::Scenes

This library provides a way to define multiple scenes within a world for the Draco ECS library.

Usage

class Inventory < Draco::World
  entity Backpack

  systems RenderInventory,
          HandleInventoryInput
end

class World < Draco::World
  include Draco::Scenes

  entity Player

  systems Render

  default_scene :overworld

  scene :overworld do
    entity Map
    entity Camera

    systems HandleMovementInput
  end

  scene :pause do
    entity ResumeButton
    entity QuitButton

    systems HandleMenuInput
  end

  scene :inventory, Inventory
end

world = World.new
world.scene = :pause

A scene can either be defined inline by using a block or can be defined as a Draco::World in another class. When the #tick method is run on the world, it runs the systems for the current scene and itself on the combined entities of the scene and the world.
