我正在尝试使用我的 Kinect 和 Python 来控制一个游戏(我的两个测试游戏是《半条命 2》和《我的世界》)。一切正常,除了一件事。游戏将响应模拟鼠标事件和模拟鼠标移动(鼠标事件通过 ctypes 完成,鼠标移动使用 pywin32 完成)。然而问题是游戏忽略了模拟按键。他们都将在聊天窗口 (Minecraft) 或开发者控制台 (Half Life 2) 中选择模拟按键,但在玩实际游戏时不会。
我尝试了几种发送按键的方法:
import win32com.client as client
wsh = client.Dispatch('WScript.Shell')
wsh.AppActivate(gameName)
wsh.SendKeys(key)
和:
import win32api
win32api.keybd_event(keyHexCode, 0, 0)
和:
import ctypes
import time
SendInput = ctypes.windll.user32.SendInput
# 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( hexKeyCode, 0x48, 0, 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( hexKeyCode, 0x48, 0x0002, 0, ctypes.pointer(extra) )
x = Input( ctypes.c_ulong(1), ii_ )
ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))
我应该指出最后一个代码不是我的,这是 Stack Overflow 上的另一个问题。
有谁知道为什么这些都不起作用以及正确的方法是什么?
