Are you ready to make amazing mobile games with the UDK?!? Well, we're ready to help you!!
Let's start off with some UDN documentation:
Getting started with Unreal Engine 3 for Mobile may seem intimidating at first, but there is a lot of info out there (and lots of friendly, helpful people around here) if you have questions. Here are some links to pages that you will find useful:
UDN Mobile Home is a good place to get started; there are many links to different facets of developing for mobile devices.
You can view your content on your mobile device using the iPhonePackager to handle signing and provisioning. Note: You must be a registered iOS developer in order to complete the signing and provisioning process.
"Switch Platform" simply restarts the editor, switching to either UDKGame or MobileGame game settings and content. You could also just load either editor using the Start Menu shortcuts created by the UDK installer.
The UDKGame and MobileGame editors are binary-compatible. That is, you can copy/rename packages and maps between the two content directories, and for the most part things will just work.
However, fully porting an existing game to mobile may require many additional steps. For example, you'll need to update your materials with mobile-specific settings, add support for touch-based input, etc. Don't forget to copy over your script code as well!
With clever tweaking of the INI files, you can make MobileGame use your UDKGame folder .. though it's not clear to me yet if it will cause any significant problems. It doesn't -seem- to, but the mobile previewer doesn't work right for me even without any tweaks, and I don't have an iThing to truly test things on.
Is there a document that details specifically what primary differences are between the Mobile and regular engine? Like I could've swore I've read all the docs, and I didn't know about the Mobile materials settings until I read it somewhere here .. I may be missing things, though, my brain isnt working right lately.
