cocos2d-x接受键盘事件，左右键, 多点触摸

概述首先在AppDelegate.cpp加入以下代码，一定要在AppDelegate::applicationDidFinishLaunching()上，声明用的。 [html]  view plain copy #if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)   HelloWorld *g_layer;      void Win32SetKeyLayer

首先在AppDelegate.cpp加入以下代码，一定要在AppDelegate::applicationDIDFinishLaunching()上，声明用的。
