“Mobilize Your Creativity – Bring Your Content to Mobile” The mobile world presents great opportunities for game developers; as technology evolves, new devices, operating systems and distribution solutions emerge and grow rapidly. However, it is becoming increasingly difficult for the game artists to fulfill their creative vision in the fragmented world of mobile. Lack of standardization and multiple technical barriers prevent the game developers from benefiting the market growing potential. In this session we will review the opportunities; the challenges (spiced up with some our own real life anecdotes) and provide helpful solutions to overcome them.

- 32. Use Case No. 1 Image Rotation
- 33. We’ve experienced this on some actual devices, and researched this issue…
- 35. createImage(image, x, y, width, height, ROTATE_180) 63 Pixels 63 % 8 = 7 56 Pixels
- 36. 63 Pixels 64 Pixels
- 37. Use Case No. 4 Using a Trackball
- 38. Normal input interface is made up of three methods We have exposed a similar interfaceonce when KeyPressed – triggered in a button is initially pressed the game engine KeyReleased – triggered once A Trackball is a different story… when a button is released KeyRepeated – triggered when a button is pressed for a long time
- 39. Trackballs are very popular in many Blackberry devices Comfortable for browsing the blackberry OS ui, but for games?...
- 41. We tried running the game on the blackberry device…
- 43. protected void keyPressed(int keyCode) { System.out.println("press - " + System.currentTimeMillis()); } protected void keyReleased(int keyCode) { System.out.println("release - " + System.currentTimeMillis()); } Running the program we got the following debug prints: Press –KeyPressed 2221 Release – 2221 Press – 2425 Release – 2425 KeyRepeated Press – 2629 Release – 2629 Press – 2937 Release – 2937 KeyReleased A constant
- 44. Our solutionBig constant Small constant Butawhat about the sensitivity? Use non-constant sensitivity parameter
- 45. But this is still not the whole story… Anatomy lesson

Notes de l'éditeur
- We will start by presenting to you some of the opportunities in the mobile market. Go on to a brief overview about the technological barriers and challenges the developers encounter.Then we will spice it up with some of the weird issues we experienced, suggest to you some of our solutions, and conclud with some final slides.
- When we founded the company, we did not start as Java Expert. What we will present is based on over 4 years of intensive JavaMe and mobile development
- Our experience –building a cross platform game engine.In games, many of the issues come to an extreme. That will be our focus.
- Super low cost – common in Asia and emmerging countries, do not run 3rd party appsFeature – most of us have these phones. When us, I do not refer to people room this room. Cooperates usually use blackberry or symbian devices, and many of you may have iPhone, which bring s us to:Smartphone –we will not get into debate regarding what is a smartphone. We refer to devices that have a better integration to the OS, and usually a native access.Unfortunally the low cost phone are taken down, despite their great number, since they are used mostly for texting and phone calls
- Both in hype and in capabilities
- Let’s have a look at the sales of smartphones cross the glob divided according to device.Dmonitated by symbian, followed by three top platforms.Android by now has increased in sales, almost to the declining size of RIM, which make the three OS pretty close
- However, when choosing your platform, it is also crucial to examine the targeted regions.If you’re going to sell your app in the USA, android might be a smart move. However, if you also want to, let’s say, expand to Eastern Europe, this will be a less optimal decision.
- Very successful in many places. Outstanding success in Canada and the Americas, and Europe, and more successful then the Android platform, except for a few regions.
- As you can see, although there’s no hype for Symbian devices in years, it is still king of platforms in most of the world. However, it almost none excitant in North America.
- All of you are not in the statistics
- Plan your project – sometimes it is impossible to converst a game to low end phone
- We will just say that there are many different JSRs which differ between devices. We should not go into the details here and even mention that JSRs and UI are usually two of the critical issues that must be dealt with when developing an application, but are not as central when devleoping games
- Talk about how we expect it to run better on the newer device
- Talk about how we expect it to run better on the newer device
- We performed a long profiling process, unable to isolate any specific method, and in the end we managed to isolate it to something like….
- Let the audience guess what’s the difference between the peppers, and tell them we’ll get back to this at the end of this use case
- We opened up the JAR where the final application runs, but the pepper image there, looked just fine
- Let the audience guess what’s the difference between the peppers, and tell them we’ll get back to this at the end of this use case
- Debugging the program we realized that the trackball acts in a very different way from the keys:Instead of sending a single "pressed" and single "released" events, multiple pairs of both are sent in a rapid succession.
- Next Step: discuss our solution "emulation of press" we connect the whole series of presses to a single continuous press
- Display the solution in a graphic way
- Replace text with images
- Stay business driven – the porting issue is an endless pit – avoid falling into it. How? Follow the moneyA common mistake is companies who develop an app for the iPhone and then try to port them to other devices.The iPhone is great, but… do not assume you can create the same app for other devices.
