WIP : viewport mode
-
fix physics view position with different ViewportModes
StarlingArt - less matrix creation
StarlingArt - less matrix creation part 2...
@gsynuh if _scaleFactor = 1, the demo won't run with the iPhone resolution.
StarlingCitrusEngine - "auto" profile
StarlingCitrusEngine - accessors to baseWidth / baseHeight + typo fix...
no need of a getter/setter if they do nothing ;)
StarlingArt - fix debug view for custom starling stage sizes
VirtualButton/Joystick - fixed default positions using starling stage instead of _ce.stage
VirtualButton/Joystick texture scale factor
StarlingState - reference to starling stage via _stage instead of having Starling.current.stage ?
StarlingState : _ce reference has StarlingCitrusEngine
so we can access baseWidth/baseHeight/scaleFactor and so on, without having to case _ce as StarlingCitrusEngine
StarlingArt debug art
wrong transformation order
@gsynuh stage is already equal to Starling Stage since it StarlingState is a Starling Sprite ;) To access flash stage, just need to do _ce.stage
