驅動級鍵盤模擬（C#）
阿新 • • 發佈：2019-02-20
我們決定來模擬“八神”的最簡單一招： 暗殺炎（就是從地上放把火過去），如果“八神”在左側，其鍵盤操作為：：↓↘→＋A或C。就是上圖中的SDU或SDJ按鍵。以SDJ為例子，在模擬這個鍵盤時要非常細心才行，我一開始這樣模擬：
m_IoSys.KeyPress(WinIoSys.Key.VK_S);
Thread.Sleep(200);
m_IoSys.KeyPress(WinIoSys.Key.VK_D);
Thread.Sleep(200);
m_IoSys.KeyPress(WinIoSys.Key.VK_J,200);
結果沒有成功。仔細研究了一下，其實我們按SDJ按鍵的時候，是先將S 按下，再將D鍵按下，然後彈起S鍵，再彈起D鍵，最後再按下J鍵的。那麼真正的過程應該這樣寫：
m_IoSys.KeyDown(WinIoSys.Key.VK_S);
Thread.Sleep(100);
m_IoSys.KeyDown(WinIoSys.Key.VK_D);
Thread.Sleep(100);
m_IoSys.KeyUp(WinIoSys.Key.VK_S);
Thread.Sleep(100);
m_IoSys.KeyUp(WinIoSys.Key.VK_D);
Thread.Sleep(10); //這個地方不能間隔太大，太大就整個動作連不起來了。
m_IoSys.KeyPress(WinIoSys.Key.VK_J, 200);
經過測試，成功模擬我們想要的操作。大家可以看到實際的模擬按鍵效果。
本程式在VS2008 + WinXP SP3 + WinKawaks1.48XP + KOF 2000 + P/S鍵盤 下除錯通過。
