cocos2d rox! it seems really easy even for someone (like me) who's
also learning python. I'm trying to familiarize myself w/ the lib and
ran into some really newbie-ish questions about layers
below is a sample doodle. My questions are:
- can I make adjust a layers size other than using scale?
- how did you find that answer in: http://cocos2d.org/doc/api/
- is it possible to apply actions (like
cocos.actions.grid3d_actions.Ripple3D()) to just a layer?
- how can I always assure that child objects to a layer have their
0,0 set to the lower left corner of the layer (or is this just the
default)?
