The
Q.Stage
object inherits from the
Q.GameObject
, as you might expect, allowing it to bind and trig-
ger events as well as add additional behaviors via components. The
init
method sets up the initial properties
on the object and executes the
scene
method if a scene object were passed in. The Quintus stage object also
supports the idea of z order, allowing objects to be sorted prior to rendering.
