Can I use Flash (ActionScripting) to create the UI or, at least, the menu screen when developing for the iPhone?
No, we have no support for ActionScript. With that in mind our JavaScript support isn’t far off from AS2, but you will have to use our GUIText/GUITextures or UnityGUI structure. Additionally, we don’t support SWFs at all.
Ok, thats good to know. thanks.
