我正在尝试使用Kinect和Python控制游戏(我的两个测试游戏是《半条命2》和《我的世界》)。 除了一件事情外,一切都正常。 游戏将响应模拟的鼠标事件和模拟的鼠标移动(鼠标事件通过ctypes完成,使用pywin32完成鼠标移动)。 然而问题在于游戏忽略模拟的按键。 它们都能在聊天窗口(Minecraft)或开发人员控制台(Half Life 2)中捕捉到模拟的按键,但在玩实际游戏时却不能。
我已经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)
并且:
import win32api
win32api.keybd_event(keyHexCode, 0, 0)
并且:
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写的,而是来自于 Stack Overflow 上另一个问题的答案。
有人知道为什么这些代码都不起作用,正确的做法是什么吗?
