The  Pla2orm  Problem  

20XX…  

Choosing  A  Solu#on  • Most  Pla9orms  With  Least  Code  

•  Licensing  Model  That  Won’t  Eat  Margins  

• Broad  Community  Support  

HTML5  • HTML5  Frameworks  • PhoneGap  • GameSalad  • Game  Closure,  AppMobi,  Ludei  

• HTML5  SHll  Sucks  • Horrible  Performance  • Gated  by  mobile  browsers  

Cocos2d  • Cocos2d-­‐X  • Straight  C++  version  of  Cocos2d  • Great  2D  library,  widely  used  • Amazing  updates  and  support  • No  web  support  

Flash  /  Adobe  AIR  •  Flash  isn’t  dead!  •  Use  Flash,  FlashBuilder,  etc.  •  AIR  NaHve  Extensions  •  Flash  game  engines  •  Starling  

Unreal  Developer’s  Kit  •  Don’t  need  a  Mac!  •  Top  of  the  line  renderer  •  25%  of  revenue  to  Epic  •  Weak  pla9orm-­‐specific  support  

Other  Op#ons  • Titanium  Studio  • Corona  • GameMaker  • Stencyl  • Marmalade  

Why  I  Chose  Unity3D:    Tech  • Best  support  for  criHcal  pla9orms  • Mobile  (iOS,  Android,  etc.)  • Web  (NaCL,  Web  Player,  Flash)  • Desktop  (Steam,  Mac  App  Store,  Win8)  • Console  

Tech  • NaHve  Plug-­‐ins  • Can  support  any  pla9orm-­‐specific  funcHonality  • Amazon  App  Store  • Google  Play  Game  Services  • Write  your  own  naHve  plug-­‐in  

Support  • Awesome  forums  • Awesome  feedback  from  support  • Twi]er!  

Asset  Store  

Business  Model  • Flat  fee  per-­‐seat  (‘perpetual’)  • Monthly  SubscripHon  • No  rev-­‐share  

Brick  Buddies  

Camera  Birds  

iOS  to  Android  with  Unity3D  

Plug-­‐ins  • Used  mostly  cross-­‐pla9orm  plug-­‐ins  

• Access  pla9orm  specific  features  (IAP,  etc.)  

Pla2orm  Specific  Code  • Only  spent  a  few  days  of  re-­‐factoring  

• Swapped  out  iOS  plug-­‐ins  for  Android  

• RunHme  pla9orm  checks  and  #IF  compiler  direcHves  

• AndroidJavaClass!  

AndroidJavaClass  AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity”)! !mWindowManager = activity.Call<AndroidJavaObject>("getSystemService","window");!!mConfig = activity.Call<AndroidJavaObject>("getResources").Call<AndroidJavaObject>("getConfiguration");!!

Screen  Sizes  •  iOS  has  3  aspect  raHos  to  deal  with  

• Made  interface  work  in  “safe  zone”  

• For  Android’s  common  16:10  raHo,  scaled  NGUI  interface  to  fit  

Android  Fragmenta#on  

Performance  and  Tes#ng  

Cross  Pla2orm  Export  Tools  • Per-­‐Pla9orm  Asset  Sehngs  • Compression  sehngs  • Filtering  

• Cache  Server  

• MulH-­‐Pla9orm  Toolkit  • Build-­‐Hme  asset  changes  

In  Summary  • Best  Business  Model  

• Widest  Pla9orm  Support  

• Best  Community  Support  

• Dead  Simple  PorHng  Process
