如何使用pywinauto模拟游戏中的键

Question

我一直在尝试各种各样的事情.我是初学者在python中的水平.Project Euler中的前两个问题.

我尝试了一些方法来尝试和模拟我玩的游戏中的键.我可以使用autohotkey和宏键盘/鼠标轻松完成此操作.但是,我想通过Python或C来实现这一目标.

我的猜测是在视频游戏中忽略了win32 api,我需要通过Direct X来模拟按键.

先感谢您.这是我最近的尝试......它失败了.

每次运行游戏的新实例时,我都必须抓取/更改句柄.

我的模拟按键可以在浏览器和记事本中使用,而不是在游戏中.不工作,我的意思是没有用户输入.

以下代码将切换到窗口,但不会模拟用户的输入.

import pywinauto
import time
from pywinauto import application
app = application.Application()
app.connect_(handle = 0x14002a)
dialogs = app.windows_(handle = 0x14002a)
dlg = app.top_window_()
time.sleep(1)
app.MapleStory.TypeKeys("%A")
time.sleep(1)
app.MapleStory.TypeKeys("%A")
time.sleep(1)
app.MapleStory.TypeKeys("%A")
time.sleep(1)
app.MapleStory.TypeKeys("%A")
time.sleep(1)
app.MapleStory.TypeKeys("%A")
time.sleep(1)
app.MapleStory.TypeKeys("%A")

我们过去的自己经历了一段漫长的旅程。尽管我们还有很多东西需要学习，但我们发现：

如果游戏在 DirectX 上运行，则发送虚拟按键将被忽略。使用 sendinput 并发送 scan_codes。

import ctypes
import time

SendInput = ctypes.windll.user32.SendInput

W = 0x11
A = 0x1E
S = 0x1F
D = 0x20
Z = 0x2C
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)

感谢 Sentdex 提供的有关机器学习的精彩教程。我一直想对一些我最喜欢的游戏执行此操作，但无法获取密钥（由于 DirectX）。
