Hi folks !
My first post here.
I just added a TouchPad library to the wiki.
video here - http://www.youtube.com/watch?v=aqGZRQRBtSI
code here - http://dosetsu.parseapp.com/blog/TouchPad.html
TouchPad.lua - base class
TouchPadCircle.lua - inherits and implements TouchPad
TouchPadRect.lua - inherits and implements TouchPad
I also add the Main.lua that i used to test with. It shows how to use the classes
and how to setup delegates to listen for callbacks. You can also use this to implement buttons.
Hope this helps !
