さて、私はゲーム用に簡単な変更を加えようとしています。これは、キーの押下をエミュレートするコードです。

#define PWNFUNC(a) static cell AMX_NATIVE_CALL a(AMX *amx, cell *params)
PWNFUNC(EmulateKeyPressINPUT)
{
    // This structure will be used to create the keyboard
    // input event.
    INPUT ip;

    // Set up a generic keyboard event.
    ip.type = INPUT_KEYBOARD;
    ip.ki.wScan = 0; // hardware scan code for key
    ip.ki.time = 0;
    ip.ki.dwExtraInfo = 0;

    ip.ki.wVk = params[2]; // virtual-key code for the "a" key
    switch(params[1])
    {
        case WM_KEYDOWN:
        ip.ki.dwFlags = 0; // 0 for key press
        break;
        case WM_KEYUP:
        ip.ki.dwFlags = KEYEVENTF_KEYUP;
        break;
    }
    SendInput(1, &ip, sizeof(INPUT));
    return 1;
}

これに関する問題は、上矢印キーを送信したいときに、numpad8 キーが送信されることです (ハードウェア キーボードが原因でしょうか?)。キーボードの矢印キーを押すと、ゲーム内の航空機が前進し、上矢印をエミュレートすると、スラスターの回転が変化します (回転の変化は数値 8 にマッピングされます)。同じことが、それぞれ下向き矢印 - num2、左向き矢印 - num4、および右向き矢印 - num6 で発生します。

何が起こっている？

無関係かもしれませんが、航空機を制御するコードを見たい場合は、これがそれです:

(PAWN - スクリプト言語)

        #define KEYPRESS_DOWN 0x0100

        if ( speed > 260.0 )
            speed = 260.0;

                if(speed < 200.0)
                {
                    EmulateKeyPress(KEYPRESS_UP,VK_DOWN);
                    EmulateKeyPress(KEYPRESS_DOWN,VK_UP);
                    sent = 1;
                    DrawText( id,50.0,160.0,0xFFFFFFFF, "GO birdy!! gooo!!!!" );

                }
                else if(speed > 210.0)
                {
                    EmulateKeyPress(KEYPRESS_UP,VK_UP);
                    EmulateKeyPress(KEYPRESS_DOWN,VK_DOWN);

            }

                DrawText( id,50.0,160.0,0xFFFFFFFF, "Something other is going on.. our relation ship is too complicated :(" );
            }

            DrawText( id,50.0,160.0,0xFFFFFFFF, "Well, f**k you too, no autopilot if you're not in an F-22.." );
        }

scancodes 2 ページとそのメイン ページによると、ハードウェアのデフォルトのスキャンコード セットは 2 で、上矢印のコードは E0,75 で、numpad8 のコードは単純な 75 です。これは、矢印キーが拡張キーであることを意味します。拡張キー フラグを有効にする必要があります。このコードを使用すると、スクリプトからデータを操作できます。

PWNFUNC(EmulateKeyPressINPUT)
{
    // This structure will be used to create the keyboard
    // input event.
    INPUT ip;

    // Set up a generic keyboard event.
    ip.type = INPUT_KEYBOARD;
    ip.ki.dwFlags = 0;
    if(params[4] == 1)
    {
        ip.ki.wScan = params[2]; // hardware scan code for key
        ip.ki.wVk = 0; // virtual-key code for the  key
        ip.ki.dwFlags |= KEYEVENTF_SCANCODE;
    }
    else
    {
        ip.ki.wScan = 0; // hardware scan code for key
        ip.ki.wVk = params[2]; // virtual-key code for the  key
    }

    ip.ki.time = 0;
    ip.ki.dwExtraInfo = 0;

    if(params[3] == 1)
    {
        ip.ki.dwFlags |= KEYEVENTF_EXTENDEDKEY;
    }
    if(params[1] == 1)
    {
        ip.ki.dwFlags |= KEYEVENTF_KEYUP;
    }
    return SendInput(1, &ip, sizeof(INPUT));
}

5、6、7、8 キーでフラグを変更し、9 と 0 で入力キーを変更できます。
