目前,我正在创建自己的函数 onPress 和 onRelease。但是,我的 onRelease 函数有问题。显然,即使我没有释放键盘,我的 onRelease 也会继续触发。
我怀疑这与 CPU 内部的周期数有关,但我不确定这个理论。不知何故,也许循环比我的帧慢,那为什么 PeerMessage 返回 false?因为没有触发任何事件。
解决方案: **在 WinProc 函数下创建一个名为 WM_KEYUP 的新案例。一旦用户离开按钮,此事件将触发。它有助于解决CPU内部发出的周期数。**
*注意:我已经更新了我的代码细节。
描述。窗口编程我有两个存储我的键盘数据的 std::array 1) InputCurr 2) InputPrev
std::array<char, 256> inputPrev;
std::array<char, 256> inputCurr;
While(TRUE) {
std::copy(InputCurr.begin(), InputCurr.end(), InputPrev.begin());
inputCurr.fill(0);
while(PeekMessage (&uMsg, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage (&uMsg);
DispatchMessage (&uMsg);
}
if(onReleased(x030)) //Button 0
//do something
}
char onReleased(char key)
{
return (inputCurr[key] && !inputPrev[key])? 1 : 0;
}
void VEInputMessage(WPARAM key)
{
inputCurr[key]= 1; //Set to true of the keyboard key
}
LRESULT CALLBACK WinProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
HDC dc; /* device context */
PAINTSTRUCT ps; /* the paint struct */
RECT rect;
UNREFERENCED_PARAMETER(rect);
switch (msg)
{
/* when the window is created */
case WM_CREATE:
break;
/* when the rectangle is drawn */
case WM_LBUTTONDOWN:
break;
case WM_MOUSEMOVE:

case WM_PAINT:
dc = BeginPaint(hWnd, &ps);
EndPaint(hWnd, &ps);
break;
/* When it's time for the window to be closed and removed */
case WM_DESTROY:
PostQuitMessage(0);
break;
case WM_KEYDOWN:
VEINPUT::VEInputMessage(wParam); //Updated the input key
if(wParam == AEVK_ESCAPE)
PostQuitMessage(0);
break;
default:
return DefWindowProc(hWnd, msg, wParam, lParam);
}
return 0;
