PORTING
Advantages of Porting
Big common code base: less bugs, less maintainance effort, less human resource
Only the things that really platform-specific are needed to be separated
How?
We built:Our own 3D engines and libraries
(Networking, Sound, UI, Debugger…) which already support multi-platform
Online System to centralize the services: User profiles, Billing, Data downloading, Multi player….
Core Packages for general features in each platform
Tips and tricks
Try to build your game without a real device first
Graphics: Use OpenGL ES 2.0Don’t hard-code. Do things explicitly.
Have separated Configuration files. Prepare your data wiselyPreprocessing is not only for C++Keep an abstract macros/classes/library
of code that using platform-specific API or behave differently on each platform
Examples – Defines/Configuration#ifdef OS_ANDROID
#define KEYCODE_BACK (4)#define KEYCODE_UP (19)#define KEYCODE_DOWN (20)#define KEYCODE_LEFT (21)#define KEYCODE_RIGHT (22)
#elif defined(WIN32) #define KEYCODE_BACK (27)
#define KEYCODE_UP (38)#define KEYCODE_DOWN (40)#define KEYCODE_LEFT (37)#define KEYCODE_RIGHT (39)
#endif
Examples – simple macro#define PLATFORM_WIN32 1#define PLATFORM_ANDROID 2#define CONFIG_PLATFORM PLATFORM_WIN32#if CONFIG_PLATFORM==PLATFORM_ANDROID#include <android/log.h>#define Log(...) __android_log_print(ANDROID_LOG_INFO, “GLGame",__VA_ARGS__)
#elif CONFIG_PLATFORM==PLATFORM_WIN32#define Log(...) printf(__VA_ARGS__);printf("\n")
#else#define Log(...)
#endif
Examples – Abstract Libraryclass TouchScreenBase { ... }class TouchScreenMobile : public TouchScreenBase { ... }class TouchScreenWin32 : public TouchScreenBase{ ... }#ifdef OS_ANDROIDtypedef TouchScreen TouchScreenMobile
#elif defined(WIN32)typedef TouchScreen TouchScreenWin32
#endif
//Usage: Just use TouchScreen Class
Examples – Abstract Library (2)class TouchScreenBase { ... }class TouchScreenMobile : public TouchScreenBase { ... }class TouchScreenWin32 : public TouchScreenBase{ ... }
//Usage: Cast to TouchScreenBase Class#ifdef OS_ANDROID TouchScreenBase* TS = new TouchScreenMobile()
#elif defined(WIN32) TouchScreenBase* TS = new TouchScreenWin32()
#endif
plan ahead, not fix laterMulti-platform support
