Python 向游戏发送按键时，它不会'；不适用于箭头按钮

我正在尝试向游戏发送键盘输入，经过大量搜索，我终于找到了一个有效的代码：

# http://www.gamespp.com/directx/directInputKeyboardScanCodes.html

import ctypes
import time

SendInput = ctypes.windll.user32.SendInput

W = 0x11
A = 0x1E
S = 0x1F
D = 0x20
Z = 0x2C
X = 0x2D
Q = 0x10
UP = 0xC8
DOWN = 0xD0
LEFT = 0xCB
RIGHT = 0xCD
ENTER = 0x1C 

# C struct redefinitions 
PUL = ctypes.POINTER(ctypes.c_ulong)
class KeyBdInput(ctypes.Structure):
    _fields_ = [("wVk", ctypes.c_ushort),
                ("wScan", ctypes.c_ushort),
                ("dwFlags", ctypes.c_ulong),
                ("time", ctypes.c_ulong),
                ("dwExtraInfo", PUL)]

class HardwareInput(ctypes.Structure):
    _fields_ = [("uMsg", ctypes.c_ulong),
                ("wParamL", ctypes.c_short),
                ("wParamH", ctypes.c_ushort)]

class MouseInput(ctypes.Structure):
    _fields_ = [("dx", ctypes.c_long),
                ("dy", ctypes.c_long),
                ("mouseData", ctypes.c_ulong),
                ("dwFlags", ctypes.c_ulong),
                ("time",ctypes.c_ulong),
                ("dwExtraInfo", PUL)]

class Input_I(ctypes.Union):
    _fields_ = [("ki", KeyBdInput),
                 ("mi", MouseInput),
                 ("hi", HardwareInput)]

class Input(ctypes.Structure):
    _fields_ = [("type", ctypes.c_ulong),
                ("ii", Input_I)]

# Actuals Functions

def pressKey(hexKeyCode):
    extra = ctypes.c_ulong(0)
    ii_ = Input_I()
    ii_.ki = KeyBdInput( 0, hexKeyCode, 0x0008, 0, ctypes.pointer(extra) )
    x = Input( ctypes.c_ulong(1), ii_ )
    ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))

def releaseKey(hexKeyCode):
    extra = ctypes.c_ulong(0)
    ii_ = Input_I()
    ii_.ki = KeyBdInput( 0, hexKeyCode, 0x0008 | 0x0002, 0, 
ctypes.pointer(extra) )
    x = Input( ctypes.c_ulong(1), ii_ )
    ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))

if __name__ == '__main__':
    pressKey(0x11)
    time.sleep(1)
    releaseKey(0x11)
    time.sleep(1)

以下是我如何在我的计划中调整它：

def press(key):
    num = KEYS[key] # Global dict which makes a mapping
                    # Of "W" to 0x11 for example
    pressKey(num)
    time.sleep(1)       
    releaseKey(num)

虽然它确实适用于“Z、X、W、B等”等字母，但它似乎不适用于箭头（上-下-左-右）。箭头在记事本中起作用，但在游戏中不起作用。如何修改此代码，使其也适用于箭头按钮？

Numpad在4、6、8和2上有箭头键。它在按那些。关闭键盘上的Numpad锁。我也有同样的问题，现在我觉得自己很愚蠢。
