我需要一些关于DirectInput的帮助,我会告诉你我要做什么。我想做的是,当我只按一个键时,我的程序会向游戏发送组合键。示例:我按"r",它会按"1"、"3"、"2"、"4"键。我从这里找到了一些代码。但它们并没有完全起作用。
public static void Send_Key_Hold(short Keycode)
{
INPUT[] InputData = new INPUT[1];
InputData[0].type = 1;
InputData[0].ki.wScan = Keycode;
InputData[0].ki.dwFlags = (int)(KEYEVENTF_SCANCODE);
SendInput(1, InputData, Marshal.SizeOf(InputData[0]));
}
public static void Send_Key_Release(short Keycode)
{
INPUT[] InputData = new INPUT[1];
InputData[0].type = 1;
InputData[0].ki.wScan = Keycode;
InputData[0].ki.dwFlags = (int)(KEYEVENTF_KEYUP | KEYEVENTF_SCANCODE);
SendInput(1, InputData, Marshal.SizeOf(InputData[0]));
}
这是我的代码和我的问题:当我只使用Send_Key_Hold时,它会按下游戏中的一个键,而其他组合键则不会按下,因为我认为第一个键被按住了。当我同时使用Send_Key_Hold和Send_Key_Release时,它不会在游戏中按下任何按钮。但在桌面上(我指的是除游戏以外的任何其他应用程序),它按下了键。
我在互联网上找到了这个例子。当我试着做和你现在一样的事情时,我自己测试了它。
[Flags]
private enum InputType
{
Mouse = 0,
Keyboard = 1,
Hardware = 2
}
[Flags]
private enum KeyEventF
{
KeyDown = 0x0000,
ExtendedKey = 0x0001,
KeyUp = 0x0002,
Unicode = 0x0004,
Scancode = 0x0008,
}
[DllImport("user32.dll", SetLastError = true)]
private static extern uint SendInput(uint nInputs, Input[] pInputs, int cbSize);
[DllImport("user32.dll")]
private static extern IntPtr GetMessageExtraInfo();
public static void SendKey(ushort key)
{
Input[] inputs =
{
new Input
{
type = (int) InputType.Keyboard,
u = new InputUnion
{
ki = new KeyboardInput
{
wVk = 0,
wScan = key,
dwFlags = (uint) (KeyEventF.KeyDown | KeyEventF.Scancode),
dwExtraInfo = GetMessageExtraInfo()
}
}
}
};
SendInput((uint) inputs.Length, inputs, Marshal.SizeOf(typeof (Input)));
}
private struct Input
{
public int type;
public InputUnion u;
}
[StructLayout(LayoutKind.Explicit)]
private struct InputUnion
{
[FieldOffset(0)] public readonly MouseInput mi;
[FieldOffset(0)] public KeyboardInput ki;
[FieldOffset(0)] public readonly HardwareInput hi;
}
[StructLayout(LayoutKind.Sequential)]
private struct MouseInput
{
public readonly int dx;
public readonly int dy;
public readonly uint mouseData;
public readonly uint dwFlags;
public readonly uint time;
public readonly IntPtr dwExtraInfo;
}
[StructLayout(LayoutKind.Sequential)]
private struct KeyboardInput
{
public ushort wVk;
public ushort wScan;
public uint dwFlags;
public readonly uint time;
public IntPtr dwExtraInfo;
}
[StructLayout(LayoutKind.Sequential)]
private struct HardwareInput
{
public readonly uint uMsg;
public readonly ushort wParamL;
public readonly ushort wParamH;
}
现在使用SendKey(0x14)
将您的T
密钥发送到活动窗口(或游戏)。
注意:您需要KeyEventF.Scancode
作为您的标志,否则wScan
属性将被忽略
