模拟GTA:SA中的键盘点击 [英] Simulate keyboard click in GTA:SA

问题描述

我正在尝试运行一个有时会模拟GTA:SA中的点击的程序.问题是它在运行时什么也不做.到目前为止，我已经尝试了以下代码:

I'm trying to run a program that sometimes will simulate clicks in GTA:SA. Problem is it doesn't do anything when running. I have tried this code so far:

IntPtr calculatorHandle = FindWindow(null, "GTA:SA:MP");
if (calculatorHandle == IntPtr.Zero)
{
    MessageBox.Show("GTA:SA:MP isn't running");
    return;
}
SetForegroundWindow(calculatorHandle);
SendKeys.SendWait("T123");

如果您告诉我代码是否有问题，我会很高兴.谢谢！

I'd be glad if you tell if something is wrong with my code. Thanks!

这是添加尼尔代码后的代码:

This is my code after adding Neill's code:

IntPtr calculatorHandle = FindWindow(null, "GTA:SA:MP");
if (calculatorHandle == IntPtr.Zero)
{
    MessageBox.Show("GTA:SA:MP isn't running");
    return;
}
SetForegroundWindow(calculatorHandle);
short key = 0x14;
WindowsMessageService.SendKey(key, KeyFlag.KeyDown);
Thread.Sleep(10);
WindowsMessageService.SendKey(key, KeyFlag.KeyUp);

推荐答案

您的第一个问题是，大多数游戏都使用DirectX输入.您将必须利用以下内容将密钥发送到游戏.另外，您需要发送上下键来模拟游戏的按键操作.

Your first problem is that most games make use of DirectX input. You will have to make use of the following to send keys to the game. Also, you would need to send up and down key to simulate the keypress for the game.

[StructLayout(LayoutKind.Sequential)]
struct MouseInput
{
    public int dx;
    public int dy;
    public int mouseData;
    public int dwFlags;
    public int time;
    public IntPtr dwExtraInfo;
}

[StructLayout(LayoutKind.Sequential)]
struct KeyboardInput
{
    public short wVk;      //Virtual KeyCode (not needed here)
    public short wScan;    //Directx Keycode 
    public int dwFlags;    //This tells you what is use (Keyup, Keydown..)
    public int time;
    public IntPtr dwExtraInfo;
}

[StructLayout(LayoutKind.Sequential)]
struct HardwareInput
{
    public int uMsg;
    public short wParamL;
    public short wParamH;
}

[StructLayout(LayoutKind.Explicit)]
struct Input
{
    [FieldOffset(0)]
    public int type;
    [FieldOffset(4)]
    public MouseInput mi;
    [FieldOffset(4)]
    public KeyboardInput ki;
    [FieldOffset(4)]
    public HardwareInput hi;
}

[Flags]
public enum KeyFlag
{       
    KeyDown = 0x0000,
    ExtendedKey = 0x0001,
    KeyUp = 0x0002,
    UniCode = 0x0004,
    ScanCode = 0x0008
}

public static class WindowsMessageService
{
    [DllImport("user32.dll")]
    private static extern UInt32 SendInput(UInt32 nInputs,[MarshalAs(UnmanagedType.LPArray, SizeConst = 1)] Input[] pInputs, Int32 cbSize);

    public static void SendInput(short keycode, KeyFlag keyFlag)
    {
        var inputData = new Input[1];

        inputData[0].type = 1;
        inputData[0].ki.wScan = keycode;
        inputData[0].ki.dwFlags = (int)keyFlag;
        inputData[0].ki.time = 0;
        inputData[0].ki.dwExtraInfo = IntPtr.Zero;

        SendInput(1, inputData, Marshal.SizeOf(typeof(Input)));
    }

    public static void SendKey(short keyCode, KeyFlag keyFlag)
    {
        SendInput(keyCode, keyFlag | KeyFlag.ScanCode);
    }
}

用法示例:

short key = 0x3B; // F1 key

WindowsMessageService.SendKey(key, KeyFlag.KeyDown);

Thread.Sleep(10);

WindowsMessageService.SendKey(key, KeyFlag.KeyUp);
