Instance Method Details

#agent(name, options = {}, &block) ⇒ Object

Declare an agent in this zone. If the agent doesn't get a location declaration, by default the agent will usually be invisible (not an interactable location) but will be instantiable as a parent.

  state = { "zone" => @name, "home_zone" => @name }.merge(options)
  builder = AgentBuilder.new(name, @engine, "type" => options["type"] || "Agent", "state" => state)
  builder.instance_eval(&block)
  @built_item.state["contents"] << name
  nil
end

#location(name, options = {}, &block) ⇒ Object

Declare a location in this zone.

def location(name, options = {}, &block)
  state = { "zone" => @name, "home_zone" => @name }.merge(options)
  builder = LocationBuilder.new(name, @engine, "type" => options["type"] || "Location", "state" => state)
  builder.instance_eval(&block)
  @built_item.state["contents"] << name
  nil
end

#tmx_location(name, options = {}, &block) ⇒ Object

This is currently an ugly monkeypatch to allow declaring a "tmx_location" separate from other kinds of declarable StateItems. This remains ugly until the plugin system catches up with the intrusiveness of what TMX needs to plug in (which isn't bad, but the plugin system barely exists.)
