The community has been busy here at Learn OpenGL ES, as many visitors have been developing fantastic games, live wallpapers, and tutorials of their own! I’d like to highlight some of the work that I have come across in recent weeks; if you’re part of the community here and would like to be featured as well, please give me a shout-out via the contact form!
Let’s say you’ve decided to develop the next viral game for Android. You now have a choice: Do you go with a pre-packaged solution, flawed and rough around the edges though it may be, or do you decide to DIY (Do It Yourself) which has the disadvantage of reinventing the wheel and spending more time writing boiler-plate code? You also need to decide if you are going to go with a commercial solution or with one of the open-source libraries available.
Here are two of the more well-known open-source libraries that won’t cost you a dime to use:
libgdx is an open-source framework which abstracts away the job of developing graphics for Android, and it also allows you to build for the desktop with only a few lines of code. It also appears to have support for OpenGL 2 on the desktop, though using standard OpenGL 2 instead of OpenGL ES 2.
You can focus on the implementation of your app or game and save development time by not having to reinvent the wheel and rewrite boiler-plate code; being able to build for different platforms with only a few lines of code is a neat thing. Rovio reportedly used forplay in the development of the WebGL version of Angry Birds.
By using a framework, you won’t learn about the finer details of OpenGL ES and other aspects of game development, and ultimately, you’ll want to learn and understand these finer details if you also want to understand the broader picture. You’ll also have to live with the design decisions and implementation details of the various frameworks, as well as any rough edges. If you’re targeting Android and the Android Market, it’s better to test on and develop for the phone rather than on the desktop — it’s better to do well on one platform than mediocre on a few.
With the wide availability of code snippets and open-source libraries, there’s no need to go either-or. You can go with an existing framework if that’s most convenient for you, or you can start building from scratch, while taking code and math from the vast array of resources available on the Internet. Be sure to check the licenses before using code from other libraries — some open-source libraries are GPL licensed, which requires you to make your source code available for others should you incorporate it into your own code.
As always, don’t hesitate to leave your comments and feedback. 🙂
