We are often asked about which iOS game engine to use. It is believed that most companies are looking for a free game engine so here is a comparison of the different open source iPhone game engines that actually have apps out there. Also these game engines now support the iPad.
The Sparrow Framework is a very lightweight 2D game engine created in Objective-C.
It was built from ground up for iPhone, iPad and iPod Touch. You can easily integrate it with your existing UIKit apps, access all iOS APIs directly and benefit from native performance.
If you have already worked with Adobe Flash or Starling, you will feel right at home: Sparrow uses the same concepts and naming schemes. Even if you’re coming from a different background, you’ll get the hang of it quickly, because everything is designed to be as intuitive and easy to use as possible.
The game framework includes all the necessary features you’d require for creating a basic 2D game such as easy animation, and a sound engine.
The Cocos2D iPhone game engine is a port of a game engine originally created in Python and converted to iPhone Objective-C. As you can tell from the name, Cocos2D is designed for 2D games, that being said, although the engine is in a 2D world, the engine includes a growing collection of high quality 3D special effects. Cocos2D has also been released on the Mac so you can ease the release on 2 platforms.
Cocos2D is the first engine to check out, while many may be turned off by the engine not supporting a 3d world, if you look at most of the top iPhone games the gameplay is 2D, in fact the iPhone’s touch screen controls can make it difficult to operate in a 3D world.
The engine provides more examples than any of the other engines out there because of the large community.
iSGL3D (iOS Scene Graph Library) is a 3D framework for the iPhone, iPad and iPod Touch written in Objective-C, enabling the creativity of developers to flourish in a 3D world without the complexities of OpenGL.
With its rich set of features, iSGL3D provides the necessary tools to develop 3D applications in an incredibly short time frame, even with a minimum of experience in 3D graphics. The principal behind iSGL3D is to make construction and manipulation of 3D scenes as simple as possible for a developer.
With a single line of code you can add a 3D object whether it is a simple primitive, a sprite (or particle) or your own imported asset. Properties on these objects allow you to modify their appearance, position, rotation and more very simply. You can add containers too to group objects and manipulate them together. In a short period of time you can build up a complex 3D scene.
The Moai SDK is an open source 2D game engine. It designed more for people who know what they’re doing. While it includes the ability to start developing a game immediately from a downloadable binary, it only supports using the FreeGLUT library on the desktop. It is designed in such a way that it expects the developer to be able to create the windowing system themselves.
The main language used with Moai is Lua. Most of the time you shouldn’t need to use C++ to extend the base engine, but the capability to do so is there. The documentation for the Lua codebase is kind of weak however, so you should be ready to do some searching to find out how to use various capabilities. You can create your games with Moai on both Windows (Visual Studio) and Mac (Xcode). In order to
submit your games to the iOS app store you will need to do so with a Mac.
The Oolong Engine is written in C++ with some help from Objective-C. It will help you to create new games and port existing games to the iPhone, the iPod touch and the iPad.
Oolong provides support for a wide variety of features and provides excellent performance.
Haxe is a multi-platform language that most notably compiles to SWF and has been used in many Flash games.
Galaxy Game Engine
The Galaxy Game Engine is a very promising engine with an extensive feature set. This is a BSD licensed 3D engine that includes some very useful tools such as a level editor, terrain editor, model viewer, particle editor, and shader IDE.
Sure, we may make this list longer, but let me stop here. The most important thing, which I’d like to notice, is that you should select the engine which fits your project needs and suits your purposes in the best way.
And what do you think? To what engine would you give your preference?

Over the years dynamic languages such as Python and Ruby have become cherished by startups. As for .Net it is more rarely heard to be used by startups. That’s interesting indeed, because this platform is definitely bigger than most of the popular ones.
So I wonder why a platform as widely adopted and supported as .NET isn’t more visible in startup culture. Let’s try figuring out the main arguments in favor and against making .Net a startup technical choice.
1. Community culture
Some people say the main reason is the culture of the .NET community itself, not anything specific to the platform. Being centered mostly around the needs of enterprise market .NET developers’ concerns are often regarding supporting legacy systems, building enterprise architectures, large systems for supporting business processes. This implies solving problems which are not so relevant for startups at least at their initial point.
As for members of the startup community, they fuss over different issues – concurrency, experience design, supporting multiple clients and browsers, etc.
As a result the startup community and the .NET community don’t overlap as much as they do for other technologies. That’s why startup founders don’t get much exposure to .Net and don’t think of it as an applicable tool for their purposes. The same way many .Net developers who want to work for hot startups don’t have as many opportunities to do so unless they abandon the platform for a more startup-friendly one or start a company themselves.
So platform doesn’t always dictate its use – that’s people who make the choice. Enterprise and startups aren’t mutually exclusive – they’re just different stages in the evolution of software, and there’s no reason why the startup community shouldn’t look at .NET as an attractive starting point for a new business.
2. Startup tech compatibility
A startup is a risky venture with no guarantee of success. So tech startups seek advantages in order to succeed. Hence startups take what big enterprises consider risky bets on technology. This objective can be achieved by using technology that is popular in startup environment.
Many features of .NET, facilitating the productivity of big companies, are not always useful to startups. There is too much choice of implementation methods. If anything, web startups are looking to have this choice taken away – their technology choices come from the subset that is built for the web.
Also it is said that innovation is quicker with other ecosystems which have a bigger set of libraries and tools. As for .Net there are a few open source projects however most of them are pretty much an implementation of concepts that have already been implemented for a while in the Java world, for example.
3. Open source vs proprietary
Although many startups don’t mind paying for tools and services, most of them still pick things based on cost. For a long time the “enterprise” level tools, services, databases, etc were hardly affordable by startups. That’s why startups adopt so much open source.
It’s also hard to justify the use of proprietary software from a business perspective. If you want to be acquired it is wise to develop your product using an open stack rather than Microsoft’s.
However luckily for many startups Microsoft saw a huge value in giving their stuff away to startups and startups have benefited greatly. Microsoft has been running their Bizspark program for several years, which eliminates most of the startup costs normally associated with employing a .NET framework. To get into the BizSpark program you just need to get checked by BizSpark team if your startup is eligible (developing a real product). Then you’ll get free licenses to basically every product they make, including SQL Server, and a free MSDN gold subscription, for 3 years. They figure 3 years is long enough for you to get going so after that they want you to pay for new licenses. The great part is that they let you keep the licenses you’re already using. So Microsoft has basically taken the cost factor completely out of the equation for new startups.
4. Velocity vs performance
Some people say that it’s all about the velocity. If you agree with an assumption that a startup goal is to find a niche vs build a product, then the goal of a startup is to learn about the market, customers, and product needs as quickly as possible. Python, Js, Ruby, etc allow you to iterate quickly without a lot of infrastructure and boilerplate. However a company that has already has a market has a little different goal, for them the objective is to build a stable product that they can maintain.
Some people say that .Net is not suitable for quick changes. This is a pretty outdated view of C# these days, it’s actually fairly easy to write extremely terse code with. As an added bonus refactoring is so incredibly easy compared to JS, Ruby, Python, etc. that it’s ideal for rapidly switching directions in code as you can refactor so fearlessly without being slowed down by massive amounts of tests. Unfortunately what’s bad about .Net is the tooling and the supporting ecosystem.
Python is much better suited to quick prototypes that can be fleshed out into a reasonably reliable product without too many headaches. The key difference comes when you have to change features mid-stream. The lack of strict typing and interfaces means you can add, change, and remove features much quicker than C# for example. On top of that, you just write fewer actual lines of code to get the same thing done, although sometimes readability can suffer if you get too concise. There is a price to be paid with Python and Ruby though and performance is the biggest one.
5. Team and project size
The team and project size always matters. So when the solution is being built with a small team, then it is easier to use something like Python. Obviously the goal is to be fast to develop in and have a bunch of libraries to be used. On the other hand when building something with a big team, you feel like using something like C#. In this case it keeps it safe to develop in and easy to catch mistakes. Any optional documentation provided by a developer is incomplete. On the contrary the quality level of the available .Net documentation is outstanding.
However if the company is starting as very small at the initial point, it hopefully grows and builds up quite a sizeable codebase by some point. Python, JS & Ruby are fine for small programs but anything more than that and they become their own enemies because the programs they make are quite brittle.
The common opinion is that .Net scales well.So, if your startup does make it, you’ll probably have a much easier time scaling the .Net stack than you would with say Ruby or PHP.
Conclusion: it’s all about stereotyping
Eventually, I found different opinions on my question of .Net being not so popular with startups such as “platform lock-in,” “no open standards,” “licensing costs.” Sure, these are issues preventing many developers from adopting .NET in the startup space, but not enough to bar all of them from using it. Most of the arguments are just stereotypes that can be dispelled under closer examination.
All languages have strengths and weaknesses. For a startup, you need to do due-diligence and research what the right language to use for your idea will be because recoding in a different language can get costly.
So do you use .Net in your startup projects? Please share your feedback and experiences with us.
The IT sector is flourishing. If you’ve used a computer for at least a couple of times in the last few years, you’ve probably noticed this. I’ve noticed it myself even more after a business trip to Stockholm where I was lucky to attend some conferences and learnt more about Swedish IT industry tendencies. These tendencies reflect our life in general. Life changes rapidly with new technologies bursting into it. And when it comes to programming languages, we get a chance to see very different trendy styles. Programming languages which were popular some years ago are not useful today. And no one can exactly predict which programming language will be popular in future. That’s why a programmer who wants to stay in developer fields has to adopt the right programming language from time to time.
As the Swedish software maker Erik Starck pointed out, “programming is about managing complexities”. And it’s really so. An understanding of at least one programming language makes an impressive addition to any CV nowadays.
It is also very difficult to get the exact number of users for any programming language. Many of us use multiple programming languages. The more experience you have, the more programming languages you use. The more programs you write or work with, the chances of using more languages rise. The larger the company, the more languages you’re likely to use.
There are a number of ways to measure the popularity of a programming language, for example, based on the number of: 1) new applications written in the language; 2) existing applications written in the language; 3) developers that use the language primarily; 4) developers that use the language ever; 5) web searches; 6) available jobs that require skills in the language; 7) developers’ favorites, etc.
My survey attempts to rank which programming languages are most popular in Sweden, each using a different measure. So, they are the following:
Python is an object-oriented programming language which allows developers to work quickly while integrating their systems more efficiently and effectively. Designed by Guido van Rossum in 1991, Python is one of the most easy to use programming languages.
Python is characterized by its use of indentation for readability, and its encouragement for elegant code by making developers do similar things in similar ways.
Top Employers: Amazon, Dell, Google, eBay, Instagram, Yahoo
Java is a class-based, object-oriented programming language founded by Sun Microsystems in 1995. Java is one of the most in-demand programming languages today for many reasons. First of all, it is a well-organized language with a strong library of reusable software components. Secondly, programs written in Java can run on many different computer architectures and operating systems because of the use of the JVM (Java virtual machine).
Top Employers: Amazon, Deloitte, Sun, eBay, Symantec Corporation, Cisco Systems, Samsung
C++ is a compiled, multi-paradigm language written as an update to C in 1979 by Bjarne Stroustrup.
Due to its high-level compatibility and object-orientation, C++ is used for developing a wide-range of applications and games which makes it a popular and sought after programming language by the employers.
Top Employers: Intel, the Math Works, Microsoft, Qualcomm, Amazon, Mozilla, Adobe, Volvo
Ruby is an open source, dynamic programming language designed by Yukihiro Matsumoto in 1995 with a key focus on productivity and simplicity .It is one of the most object-oriented languages in the world.
Ruby is a mix of elegant syntax which is easy to read and write and hence it has attracted many organizations and developers.
Top Employers: Spokes, VMware, Accenture, Cap Gemini, Siemens, BBC, NASA
Top Employers: Microsoft, Sales Force, IBM, Yahoo, Dell
C# is a compiled, object-oriented language developed by Microsoft.
It is highly used on Windows platform and labelled as the premium language for Microsoft .NET framework. C# is known for strong typing, procedural and functional programming discipline which is the reason it has acquired so much popularity.
Top Employers: Microsoft, HP, Digi-Key Corporation, Allscripts, Intel
Those are the top 6 programming languages which are in great demand among Swedish developers.
And one more thing: remember that opinions are like noses, everyone has one and they all smell ;) If you disagree, please feel free to email me or write your own opinions in the comments.
This time as a part of cross platform development I’d like to make a short review of Mono project’s implementations/frameworks – MonoTouch and Monodroidthat allow creating applications using .NET framework and languages.
MonoTouch is a framework that allows developers create iPhone applications using the compilation of C# and reusing the existing .NET source code, libraries and skills.
The MonoTouch includes:
• Mono for the iPhone, iPad and iPod Touch
• C# and .NET compilers – on the iPhone you will need to compile the existing C# code and tools with the help of MonoTouch compiler to make sure that all the assemblies are referenced.
• .NET Bindings to Native APIs – MonoTouch compiler turns to compile the .NET libraries and base assemblies to create native iPhone applications.
• Mac oriPhoneSDK -includes the Xcode IDE, iPhone Simulator, and a suite of additional tools for developing applications for iPhone, iPad and iPod Touch.
• MonoDevelop Integrationhelps developers to integrate all features/toolsets from the integrating.NET platform to the target iPhoneenvironment from zero in no time
• Libraries that bind the native CocoaTouch APIs – toolsets that help to create native application interfaces for iPhone, iPad and iPod Touch
Mono for Android (MonoDroid)is a software development environment kit that allows to create the applications that run on Android phones and tablets.
Mono for Android consists of the core Mono runtime, the Mono for Android bindings to the native Android APIs, a Visual Studio 2010 plug-in to develop Android applications and an SDK that contains the tools to build, debug and deploy your applications. The Visual Studio 2010 plug-in allows developers to use Visual Studio 2010 to develop, debug and deploy their applications to an Android simulator, an Android device, or the Android Application Store.
Being the customer of Mono product you get one-year subscription to its product updates. The updates engaged the bug fixes and API changes. You could check the latest updates for Mono on the website called Xamarian Developer Center following this linkhttp://docs.xamarin.com/.
One of the latest upgrades released in May of 2012 by Xamarian Mono for Android is considered the research project called XobotOS.
XobotOS – the attempt to put C# code in the place of removed Java code in Android operating system. The idea is to write native code using C# instead of Java seems to extend the opportunities of Mono project. As the developers say the transition from Dalvik to Mono virtual machine performed good results like high-performance and low-battery consuming. Sharpen was chosen as the tool convertor for porting million lines of Java code to C#. It was upgraded for XobotOs and presented as its part release. The next goal of the company isto provide the direct access to the graphics library Skia for building applications.
What is the pricing?
Monotouch/MonoDroidare available in Professional Edition and Enterprise Editions: Monotouch/MonoDroid costs $399 for the entry level Professional edition and $999 and $2,499 for the Enterprise and Enterprise Priority version. A trial version is available which isn’t time limited but only allows deployment to an iPhone simulator.
The development of applications using cross platforms development approach seems to give the right idea for the developers how to manage with different environments and languages. Having reviewed the Mono project frameworks the advantages both of them may be summed up as follows:
– Applications written in C# for Android (MonoDroid) could be easily ported to iOS (MonoTouch);
-The source code written on C#, could be reused in MonoDroid and MonoTouch;
– The full support of C#: Language Integrated Query (LINQ), delegates, lambdas, events, garbage collection and many other features
– The support of Visual Studio and XCodefor bothMonoDroid and MonoTouch
– New challenges and updates guides
If you know something about programming with MonoTouch/ModoDroid and you have anything to add to my review, please, feel free to share your thoughts and experience on this point.
