What You Need to Know About Developing Games for BlackBerry
Originally appeared as sponsored content from RIM on Gamasutra.
The opportunity is now for BlackBerry game developers. Why don’t you play?
If the BlackBerry platform hasn’t been on your radar for game development, it’s time to take a second look. With the new BlackBerry Playbook 2.0 and BlackBerry 10 OS the opportunity for game developers to fill a user need is stronger than ever. BlackBerry PlayBook users want high quality, entertaining games and apps and BlackBerry AppWorld is ready for the influx:
What you need to know about developing games for
BlackBerry
The BlackBerry Native SDK for Tablet OS gives you the ability to create rich C/C++ games. Native SDK (NDK) is a development toolset that allows you to harness the power of the BlackBerry PlayBook. Combining the speed and stability of the QNX Neutrino Real-Time Operating System with the Eclipse-based QNX Momentics development environment, the Native SDK is designed for developers who need full access to all that the BlackBerry PlayBook has to offer. And the Native SDK gives you a set of C and C++ APIs that expose all the tools needed to create powerful and dynamic applications. The capabilities include the following:
The Native SDK isn’t the only option for developing applications for the BlackBerry PlayBook – depending on your needs, the WebWorks or Adobe Air platforms could be the better choice.
Four simple steps to getting started
1. Download – The BlackBerry Native SDK to Tablet OS is available for download here: https://bdsc.webapps.blackberry.com/native/download/
2. Get started - https://bdsc.webapps.blackberry.com/native/documentation/getting_started.html
The BlackBerry Native SDK for Tablet OS includes all of the tools that you'll need to start developing applications for the BlackBerry PlayBook tablet, including a compiler, a linker, libraries, the QNX Momentics IDE with its full suite of debugging and profiling tools, as well as command line tools.
When it comes to testing your application, you can test it using a BlackBerry PlayBook tablet or the BlackBerry Tablet Simulator. Some set up steps are required only if you're using one testing environment or the other. You can find a summary of the steps you need to perform to get up and running with the Native SDK here: https://bdsc.webapps.blackberry.com/native/documentation/getting_started.html
3. Learn – Be sure to check out the Developer’s Guide, Tutorials and Libraries available in the BlackBerry Native SDK:
Additional resources give you an advantage
You may also want to take advantage of blackberry.github.com, where you’ll find many Open Source game engines and libraries ported and available:
The time is right, the platform is ready and the market is eager. Browse the current BlackBerry App World game catalog to see some fantastic examples of current games available on the BlackBerry platform. Then use the resources above to start developing your own game and help the BlackBerry PlayBook live up to its name. Start playing.

10 free and amazing tools for Windows PCs
Your Windows PC may not come with too much software pre-loaded , but you don't need to spend anything to get these amazing tools, says ET.
CAMSTUDIO - RECORD YOUR SCEEN ACTIONS
This nifty piece of software can record whatever you're doing on the screen and make it into a video. Let's say you need to demonstrate something on your PC to a friend, family member or broadcast it to the web - you start CamStudio, click record, minimise the windows and then go about what you need to do.
Once done, bring up CamStudio, stop recording and you'll get a high-quality AVI video file of all your actions. It's just so much simpler and clearer than using a camera to record a screen. Get it from www.camstudio.org.
CROSSLOOP - USE IT TO ASK FOR REMOTE HELP
This is what you need to use if you get stuck with something. With Crossloop, anyone can connect to your computer and temporarily take over - with your permission of course. You don't need to worry about complicated VNC clients or IP addresses, just as long both PCs/Macs have Crossloop installed and have decent internet connections, they can connect to each other.
Connections are secure and only possible using a password - random passkeys are generated each time it starts. Get it from www.crossloop.com.
DEXPOT - VIRTUALISE YOUR OWN DESKTOP
This is a great utility for virtual desktops. Let's say you like have multiple windows open at the same time - so many that your poor desktop and taskbar are stressed to the max. With Dexpot, you have have four different desktops - each operating like an individual computer.
You can have different windows and different programs running in each, and switch between them with a keyboard shortcut.It's especially useful if you're using a laptop with a smaller screen. Get it from www.dexpot.de.
ERASER - SECURELY REMOVE FILES
When you're selling or giving away an old computer or hard drive, spare a thought for all your data which will probably still be on it (even if you delete) and easily recoverable with free software like Recuva.
With Eraser, you can securely erase all your data (or targeted files and folders) so that it can never be accessed again. Eraser overwrites your existing data with random patterns and you can choose the level of security you prefer. Get it from www.eraser.heidi.ie.
KEEPASS - ONE PASSWORD FOR ALL
If you're fed up with trying to remember multiple passwords, KeePass is the answer. It's an open-source password keeper that keeps everything in a highly encrypted database. You can store passwords, credit card information, bank IDs and so on - secure with one master password - and your data will be encrypted on your machine itself, using the most secure encryption algorithms currently available. Get it from www.keepass.info.
RECUVA - GET YOUR DELETED FILES BACK
With Recuva, you can recover documents that you have accidentally deleted, either from your computer's built in hard drive, an external one, a connected digital camera or even a USB flash drive.
The reason this works is simple - when you click delete, the file isn't actually deleted, it just becomes hidden, freeing up space and ready to be overwritten with something else. As long as you haven't overwritten loads of data on it already or formatted the memory device, it should work fine. Get it from www.piriform.com/recuva.
