在OnCreate中绑定事件监听
KlayGE::InputEngine inputEngine KlayGE::Context::Instance().InputFactoryInstance().InputEngineInstance();KlayGE::InputActionMap actionMap;actionMap.AddActions(actions, actions std::size(actions));action_handler_t input_handler MakeSharedPtrinput_signal();input_handler-Connect([this](InputEngine const sender, InputAction const action){this-InputHandler(sender, action);});inputEngine.ActionMap(actionMap, input_handler); // 获取joystic_设备for (size_t i 0; i inputEngine.NumDevices(); i){auto const device inputEngine.Device(i);if (device-Type() InputEngine::IDT_Joystick){joystick_ checked_pointer_castInputJoystick(device);}}主要的消息处理函数InputHandler实现
void InputCaps::InputHandler(KlayGE::InputEngine const sender, KlayGE::InputAction const action)
{switch (action.first){case KeyboardMsg:{key_str_.clear();InputKeyboardActionParamPtr param checked_pointer_castInputKeyboardActionParam(action.second);for (uint32_t i 0; i 0xEF; i){if (param-buttons_state[i]){key_str_ key_name[i] L ;}}}break;case MouseMsg:{InputMouseActionParamPtr param checked_pointer_castInputMouseActionParam(action.second);std::wostringstream stream;stream param-abs_coord.x() param-abs_coord.y() ;stream param-move_vec.x() param-move_vec.y() param-wheel_delta ;for (uint32_t i 0; i 8; i){if (param-buttons_state (1UL i)){stream button i L ;}}mouse_str_ stream.str();}break;case JoystickMsg:{InputJoystickActionParamPtr param checked_pointer_castInputJoystickActionParam(action.second);std::wostringstream stream;stream param-thumbs[0].x() param-thumbs[0].y() param-thumbs[0].z() ;stream param-thumbs[1].x() param-thumbs[1].y() param-thumbs[1].z() ;stream param-triggers[0] param-triggers[1] ;for (uint32_t i 0; i 16; i){if (param-buttons_state (1UL i)){stream button i L ;}}joystick_str_ stream.str();if (joystick_){for (uint32_t i 0; (i joystick_-NumVibrationMotors()) (i 2); i){joystick_-VibrationMotorSpeed(i, param-triggers[i]);}}}break;case TouchMsg:{InputTouchActionParamPtr param checked_pointer_castInputTouchActionParam(action.second);std::wostringstream stream;stream touch_name[param-gesture - 0x300] ;if (param-gesture !

}UI
ui使用内置的ui解析脚本uiml格式文件,从外部获取一个特定尺寸的图片作为按钮显示在指定位置
?xml version1.0 encodingutf-8 standaloneno?

/ui在OnCreate函数中加载ui资源
KlayGE::UIManager::Instance().Load(*KlayGE::ResLoader::Instance().Open(InputCaps.uiml));在DoUpdateOverlay函数中渲染 KlayGE::UIManager::Instance().Render();在Onsize时更新
KlayGE::UIManager::Instance().SettleCtrls();编写本例子遇到的坑

很明显CreateMutex是windows kernel32中的api函数但KlayGE却导出了一个同名的函数导致函数签名错误。KlayGE默认使用unicode字符集我的项目未设置使用了多字节结果就成了CreateMutexA。
最终的解决办法
ADD_DEFINITIONS(-DUNICODE -D_UNICODE)但是最好不要让自己的函数名称和常用库的API同名这里出现冲突也和window的unicode使用宏定义有很大原因如下
#ifdef UNICODE
#define CreateMutex CreateMutexW
#else
#define CreateMutex CreateMutexA
#endif // !UNICODE最终效果 源码
