我该如何使用DirectInput模拟按键?我目前已经有了初始化代码(但是不确定是否正确):
#include <dinput.h>
#pragma comment (lib, "dinput8.lib")
#pragma comment (lib, "dxguid.lib")
LPDIRECTINPUT8 din; // the pointer to our DirectInput interface
LPDIRECTINPUTDEVICE8 dinkeyboard; // the pointer to the keyboard device
BYTE keystate[256]; // the storage for the key-information
void initDInput(HINSTANCE hInstance, HWND hWnd); // sets up and initializes DirectInput
void detect_input(void); // gets the current input state
void cleanDInput(void); // closes DirectInput and releases memory
那么有人能向我展示如何模拟在游戏中按下左箭头键吗?
