Get your iPhone game to 2,000 handsetsMikko UromoDirector, Developer Relations & OutsourcingGameHousemuromo@real.com

This session A little background What’s our approach Development details Hopefully time for some Q&A

Who we are

What we look like

What we do

So, you’re developing for the iPhone!

Mobile is challenging Expensive Fragmentation Carriers Backfills

What’s our approach? Target the whole market Hide fragmentation Cost effective development & QA Support new devices from day one

No magic tricks …but close to a silver bullet Scalability is key EMERGE™ Guidelines

Choose your battles Low-end, old devices, coverage

requirements… Good game experience! Touch vs. keys Connectivity & social gaming Future benefits

How do we do it?

Develop the best version Best possible experience Don’t branch development Focus on touch & high-end No limitations!

Target the Other Devices Finish assets Optimize & fix bugs Make sure everything is scalable Get the game down to 64k Help automate post-production

Our tools

EMERGE™ A cross-platform game

development framework Used in 70+ titles 2,000+ devices supported iPhone, Android, J2ME, BREW,

Flash, DSi, Windows Mobile…

The framework Abstraction layer Native implementations of core API Pluggable modules Customizations Improvements help all games

Sample code#include “common.cjavai”#define FP 10

global int_array tileMap;

global void loadLevel() {tileMap = data_getIntArray_TILEMAP();for (int i=0; i<array_length(tileMap); i++) doSomething(tileMap[i]);

}

global void game_paint() {renderBackground();gfx_drawImage_SPACESHIP(shipX>>FP,

shipY>>FP, ALIGN_LT, 0);

}

Handset profiles One for each supported device Contains benchmark data Games and EMERGE adapt

automatically SKU can work on multiple devices

In practiceStep 1:

Step 2:SP3_DROP_HIGHLIGHT_FONTSP3_DISABLE_KANJI_GRAPHICS

SP3_DROP_LARGE_TROPHY_ICONS

Step 3:SP3_DISABLE_INTROSP3_DROP_AUDIENCESP3_DISABLE_CAPTIONFONT

...

What our QA does Adjust three numerical “sliders” Possible to tweak SKUs manually

Porting as QA sees itDevice memory <= 300k:

SP3_DROPFEATURES_MEMORY = 10

Benchmarked FPS < 10:SP3_DROPFEATURES_SPEED = 8

Nokia N96:SP3_DROPFEATURES_MEMORY = 1

Samsung ZX20:SP3_DROPFEATURES_SIZE = 8

Porting as devs see it#ifdef USE_LESS_PARTICLES

#define MAX_PARTICLES 20#else

#define MAX_PARTICLES 400#endif

global void drawBackground() {#ifdef DISABLE_BACKGROUND

gfx_setColor(BG_COLOR);gfx_fillRect(0, 0, X_RES, Y_RES);

#elsegfx_drawImage_BACKGROUND(X_CEN, Y_CEN,

ALIGN_HCVC, 0);#endif}

The logistics QA takes less than 1h per handset Over 10,000 SKUs per game Build farm Track submissions & coverage Large-scale DB solution

The benefits Cheaper dev and post-production Better game quality 100% handset support Day one backfills & full back

catalogue support Customizations

The big takeaway? There’s more than the iPhone You can target the entire market

That’s it!
