Inthis case, the implementation is modified by the specialist developerfor that platform within Ideaworks3D, and the workaround is appliedas generically as possible and either enabled automatically (if it ispossible to detect the fault within code) or via a configuration optionwithin the device profile.Ideaworks3D maintains a formal process for ‘certifying’ handsets beingsupported by the solution. This process involves running a large set ofunit tests, followed by system testing our previously released titles.
Anyrequired device profile changes or workarounds can then be made andtested. Once this is complete, an updated SDK is released with officialsupport for the handset. In practice however, for a platform that hasa relatively mature (>5 devices certified) implementation, the handsetsusually can be certified without modification, or, at the least, require datadriven rather than code changes to Airplay System. Given that the deviceprofile script can be edited by users of the SDK, in these cases, deploymentto new handsets can take place independently of Ideaworks3D.Figure A.1 outlines the processes for adding support for new devicesand platforms to the solution.Note: OpenKODEIdeaworks3D has been a very active member of the Khronos working group defining the OpenKODE API, and Airplay will fully supportOpenKODE when ratified.

Many key issues have been raised by Ideaworks3Dand embraced by the OpenKODE specification team. Therefore, gamesdeveloped for OpenKODE and those developed using other Khronos APIsare seamlessly supported within the solution and can take advantage ofall the features of both the development and deployment environments.Index2D graphics 11–12, 31–2, 111,121, 227–32, 253, 282–9accelerated drawing operations121games platform comparisons11–12, 31–2, 111N-Gage 2532.5G networks 4–5, 9, 11–12, 393D audio 152, 1553D graphics 11–12, 14–15, 30,31–2, 61–3, 66, 105, 111,152, 200–8, 231–4, 268–74,316–183D motion sensors 178, 179–80,198–207API overview 203–4concepts 198–207key classes 203–5Symbian OS 203–7types 2033G networks 8, 11–12, 39, 159,189A-GPS see assisted GPSAAC see advanced audio codingAardman Animation 65–6abort/restart sequence, DSA76–8, 82–3, 88–90AbortNow 75–8, 82–3, 88–90accelerated codecs, hardware115–16, 121, 125–8, 224–6,231–4accelerometer, Wii 199–207,318ActionScript, Flash Lite 322–3,324–31, 332–5ActionScript Virtual Machine(AVM) 322–3, 324–9ActivateL 47–9active objects 43–60, 77–90see also eventsgame loops 43–60, 77–83pre-emption restrictions 48–9active scheduler 46–9, 77–90see also RunLgame loops 46–9, 77–83ADD 236AddDataListener 206–7AddForegroundObserverL76–8addSnapEventListener 293ADF see application descriptor fileAdobesee also Flash LiteBridge 331–2Creative Suite 321, 327–8,329–33Device Central 331–2Flash Professional CS3 321,327–8, 329–33Adobe Integrated Runtime (AIR)322–3advanced audio coding (AAC)125–8, 148–9, 153advertising space 26AI see artificial intelligenceAI-takeover technique, multiplayerconnection drops 158AIR see Adobe Integrated RuntimeAirplay 14, 37, 165–71, 226,237, 341–50art development costs 343,346–7binary format 343–4business challenges 343–50certification issues 348–9components 165–6, 341–2cost reductions 37, 342–50debugging costs 343, 345–6deployment costs 343, 347–8development costs 343,344–5, 346–7OpenKODE 226–7porting costs 237, 343–4Airplay Online 165–71, 342background 165–71, 342custom services 166, 170–1,342352Airplay Online (continued )login services 166–7, 169–70polling style 167–9servers 166–70service builder 170–1standard services 165–7, 342transport protocol 166,167–70, 342Airplay Studio 14, 341–2, 346–7Airplay System 37, 341–2, 344AIX 218AknIconUtils 106–7AllFiles 219–20Alltel 21alternative reality, concepts 175,177–8ALWAYS BUILD AS ARM 236AMR format 125–8, 153AMS see Application ManagementSystemanimations 65–6, 98–9, 104anti-tearing techniquessee also tearing problemsAPI overview 87–8, 111concepts 62, 84, 86–90, 111key classes 87mechanism 87–8Apache 173APIs 12, 28–9, 30–2, 35–6,61–121, 182, 203–4, 209,224–7, 249–55, 265–71,303–13, 317, 343–4, 348–503D motion sensors 203–4anti-tearing APIs 62, 86–90,111camera overview 182drawing overview 70–1,110–11DSA overview 75–6, 110–11i-mode extension APIs 303–13ICL overview 100Java ME 265–71, 317less useful APIs 121location overview 193N-Gage 249–55OpenKODE 224–7, 348–50rendering overview 112RGA APIs 249–54vibration overview 209INDEXvideo player utility overview116appendix 341–50Apple 7, 61, 218, 333application areasee also APIsdefinition 71application descriptor file (ADF)300–10, 315Application Management System(AMS) 273–89see also MIDletsapplication services layer, SymbianOS 3–4AppUi 108Arena system architecture, N-Gage172–3, 241–2, 243–4,260–1, 290ARM processors 29, 60, 226,236, 343–6see also CPUsart development costs, Airplay343, 346–7artificial intelligence (AI) 158,177–8, 189, 223ASR 236ASSERT macro 48assisted GPS (A-GPS) 190–1Asteroids 44–5, 63Attack of the Killer Virus 179attract mode, concepts 55–7audio 39, 44–6, 47–9, 116,123–55, 228–30, 253, 275–6see also sound effects3D audio 152, 155background music 142–50best practices 150–1buffers 133–42clip player 128–34codecs 124–34, 148–50,228–9concepts 123–55, 228–30,253controller plug-ins 124–8design considerations 125–6,133, 275–6DevSound 124–8, 135, 136,138–42digitized music streaming147–8error cases 127–8, 130–4formats 125–8, 136–8future prospects 39game loops 44–6, 47–9graphics ascendancy 123Helix DNA 153interruption models 133Khronos Group 153–5latency problems 128, 133,135–8, 140–2MIDI 123–4, 142–7, 152–3,229–30, 253MMF 116, 124–55MobileBAE 152–3multiple effects 133–8N-Gage 253OpenMAX...
