Initial Impressions of Unity3D

After evaluating 3d engines for iOS development I’ve decided we’re going to go with Unity3D.

I would prefer a native Objective-C engine but the ability to deliver for multiple platforms is very attractive (Unity can deploy to Android, iOS, Mac, Linux, XBox 360, and the Wii).

Unity development so far has been straight forward – scripts can be in c# or javascript – I’ve created several 3d scenes, used the extensive resources from the forum and Unity Answers to create a ship that uses realistic physics to move in orbit. The Unity Asset store has thousands of additional resources for Unity3D dev. Initially I’m using atmospheric planets and vectrosity for line drawing.

We play tested the game as turn based and real time multi-player – I was initially planning on a turn based approach using Apple’s Game Center for iOS but the game plays much better in real time. We evaluated several multi-player network solutions and are going to go with Photon Cloud  – very well integrated with Unity, a great price, and should be able to scale.

Using Parse to add a backend to your iOS app

We’ve had to write over a dozen server back ends for iOS applications. There is a lot of manual work involved, no matter what platform you choose (we’ve used Google App engine or custom php solutions based on Joomla). There is the code and database development on the server side, plus a lot of code on the iOS side to handle the calls to the server, error handling, etc. It’s a royal pain and something we’d like to avoid in the future if possible.

Parse is a new service that simplifies back end development for iOS immensely – it can take literally minutes to add a simple server side component to your iOS app.

Pricing is free in Beta and looks very reasonable going forward as well.

We recently used Parse to add server functionality to an iOS Math application for YourTeacher.com. The app stores user preferences to a simple Parse object. Adding Parse to our project, testing, and deploying took less than an hour. Performance is good – besides being able to save and retrieve standard dictionary objects you can use Parse to store and manipulate remote files and geo location objects.

They have a very good overview of the integration process for iOS, plus the API is available as a REST service and for the Android as well.
