好吧，我正在尝试对游戏进行简单的修改，这是模拟按键的代码:
#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;
}
问题在于，当我想发送向上箭头键时，会发送小键盘 8 键(可能是因为我的硬件键盘？)。 当我按下键盘上的箭头键时，游戏中的飞机会前进......当我模拟向上箭头时，我的推进器会改变旋转(旋转变化映射到数字 8)。 同样的情况分别发生在向下箭头 - num2、向左箭头 - num4 和向右箭头 - num6 上。
这是怎么回事？

可能不相关，但如果您想查看控制飞机的代码，就是这样:
(它在 PAWN - 一种脚本语言中)
#define KEYPRESS_DOWN 0x0100
#define KEYPRESS_UP 0x0101
GetMovementSpeed(pos[0][0],pos[0][1],pos[0][2],true);
new Float:speed = floatsqroot(pos[0][0]*pos[0][0]+pos[0][1]*pos[0][1]+pos[0][2]*pos[0][2])*174.0;
if ( speed > 260.0 )
speed = 260.0;
if(GetVehicleModel() == 520)//f-22 airplane
{
static sent = 0;
if(IsKeyDown(VK_TAB))
{
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_DOWN,VK_DOWN);

最佳答案
根据scancodes 2 page和它的主页，硬件默认扫描码集是 2，向上箭头的代码是 E0,75，对于 numpad8 只是普通的 75，这意味着箭头键是一个扩展键，所以你需要启用扩展键旗帜。此代码成功地使您能够操作脚本中的数据:
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));
}
脚本的示例用法:
GetMovementSpeed(pos[0][0],pos[0][1],pos[0][2],true);
new Float:speed = floatsqroot(pos[0][0]*pos[0][0]+pos[0][1]*pos[0][1]+pos[0][2]*pos[0][2])*174.0;
if ( speed > 260.0 )
speed = 260.0;
