C＃在游戏应用程序中保存密钥

Question

我正在尝试制作一个C＃应用程序，它将控制游戏。我试图做的是例如：按住A键150ms，按住左箭头500ms等等。 我搜索了很多，我发现下面的代码。我的程序首先瞄准游戏，然后拿着钥匙。

I'm holding the keys this way: 

Keyboard.HoldKey(Keys.Left); 
Thread.sleep(500); 
Keyboard.ReleaseKey(Keys.Left); 

下面是键盘类：

public class Keyboard 
{ 
    public Keyboard() 
    { 
    } 

    [StructLayout(LayoutKind.Explicit, Size = 28)] 
    public struct Input 
    { 
     [FieldOffset(0)] 
     public uint type; 
     [FieldOffset(4)] 
     public KeyboardInput ki; 
    } 

    public struct KeyboardInput 
    { 
     public ushort wVk; 
     public ushort wScan; 
     public uint dwFlags; 
     public long time; 
     public uint dwExtraInfo; 
    } 

    const int KEYEVENTF_KEYUP = 0x0002; 
    const int INPUT_KEYBOARD = 1; 

    [DllImport("user32.dll")] 
    public static extern int SendInput(uint cInputs, ref Input inputs, int cbSize); 

    [DllImport("user32.dll")] 
    static extern short GetKeyState(int nVirtKey); 

    [DllImport("user32.dll")] 
    static extern ushort MapVirtualKey(int wCode, int wMapType); 


    public static bool IsKeyDown(Keys key) 
    { 
     return (GetKeyState((int)key) & -128) == -128; 
    } 

    public static void HoldKey(Keys vk) 
    { 
     ushort nScan = MapVirtualKey((ushort)vk, 0); 

     Input input = new Input(); 
     input.type = INPUT_KEYBOARD; 
     input.ki.wVk = (ushort)vk; 
     input.ki.wScan = nScan; 
     input.ki.dwFlags = 0; 
     input.ki.time = 0; 
     input.ki.dwExtraInfo = 0; 
     SendInput(1, ref input, Marshal.SizeOf(input)).ToString(); 
    } 

    public static void ReleaseKey(Keys vk) 
    { 
     ushort nScan = MapVirtualKey((ushort)vk, 0); 

     Input input = new Input(); 
     input.type = INPUT_KEYBOARD; 
     input.ki.wVk = (ushort)vk; 
     input.ki.wScan = nScan; 
     input.ki.dwFlags = KEYEVENTF_KEYUP; 
     input.ki.time = 0; 
     input.ki.dwExtraInfo = 0; 
     SendInput(1, ref input, Marshal.SizeOf(input)); 
    } 

    public static void PressKey(Keys vk) 
    { 
     HoldKey(vk); 
     ReleaseKey(vk); 
    } 
} 

及其在记事本/浏览器等的工作，但它不是在任何游戏中工作，无论全屏或窗口模式。 你能帮我弄清楚如何在全屏应用程序/游戏中保存按键吗？ 谢谢！

Answer 1

我Windown API和SendInput做到了方法。

Answer 2

“Hold键用于150毫秒，保持500毫秒左箭头”

见，如果这个工程：

 Keyboard.HoldKey((byte)Keys.A, 150); 
     Keyboard.HoldKey((byte)Keys.Left, 500); 

使用：

public class Keyboard 
{ 
    [DllImport("user32.dll", SetLastError = true)] 
    static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo); 

    const int KEY_DOWN_EVENT = 0x0001; //Key down flag 
    const int KEY_UP_EVENT = 0x0002; //Key up flag 

    public static void HoldKey(byte key, int duration) 
    { 
     int totalDuration = 0; 
     while (totalDuration < duration) 
     { 
      keybd_event(key, 0, KEY_DOWN_EVENT, 0); 
      keybd_event(key, 0, KEY_UP_EVENT, 0); 
      System.Threading.Thread.Sleep(PauseBetweenStrokes); 
      totalDuration += PauseBetweenStrokes; 
     } 
    } 
} 

Answer 3

你可以得到它与工作，这为按住键的伟大工程：

public class Keyboard 
{ 

    const int PauseBetweenStrokes = 50; 
    [DllImport("user32.dll", SetLastError = true)] 
    static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo); 

    const int KEY_DOWN_EVENT = 0x0001; //Key down flag 
    const int KEY_UP_EVENT = 0x0002; //Key up flag 

    public static void HoldKey(byte key, int duration) 
    { 
     keybd_event(key, 0, KEY_DOWN_EVENT, 0); 
     System.Threading.Thread.Sleep(duration); 
     keybd_event(key, 0, KEY_UP_EVENT, 0); 
    } 
}
