Class: Pixiurge::Display::Container

Inherits:
Pixiurge::Displayable show all
Defined in:
lib/pixiurge/displayable/container.rb

Overview

Sometimes it's useful to just have a container with one or more other Displayables inside. This allows both multiple Displayables without a custom type (e.g. a humanoid with a particle source attached) or to have multiple pieces with multiple transforms or animations (e.g. a shadow as a separate sprite that doesn't move up and down when the body jumps.)
