    HWND hwndChild = GetWindow(hWND, GW_CHILD);

     PostMessage(hwndChild, WM_KEYDOWN, 0x44, 0);

    PostMessage(hwndChild, WM_KEYUP, 0x44, 0);
    ``` trying to **hold **a key down for a certain time, but what i get is instead the key being pressed twice (presumably at WM_KEYDOWN and at WM_KEYUP)

take a look at the keybd_event

What are you making ducklett

real dragon Mar 3, 2024, 4:44 PM

#

real dragon take a look at the keybd_event

you can press and release after the sleep

zinc flame Mar 3, 2024, 4:44 PM

#

primal steeple What are you making ducklett

trrying to make a game helper

primal steeple Mar 3, 2024, 4:44 PM

#

zinc flame trrying to make a game *helper*

you can say cheats no one cares

#

what game

zinc flame Mar 3, 2024, 4:45 PM

#

real dragon you can press and release after the sleep

but does it work for apps that are in the background?

zinc flame Mar 3, 2024, 4:45 PM

#

primal steeple what game

brawlstars

primal steeple Mar 3, 2024, 4:45 PM

#

yeah should work

zinc flame Mar 3, 2024, 4:45 PM

#

the same code worked in python

primal steeple Mar 3, 2024, 4:45 PM

#

I mean like

#

That method

zinc flame Mar 3, 2024, 4:45 PM

#

but then in c++ it doesnt :/

zinc flame Mar 3, 2024, 4:45 PM

#

primal steeple That method

alright thanks

#

ill take a look

primal steeple Mar 3, 2024, 4:45 PM

#

if it has an anticheat

#

opening handles is a no no

real dragon Mar 3, 2024, 4:46 PM

#

zinc flame but does it work for apps that are in the background?

test it

primal steeple Mar 3, 2024, 4:46 PM

#

i never played brawlstars

zinc flame Mar 3, 2024, 4:46 PM

#

primal steeple if it has an anticheat

nah, its a mobile game so im on an emulator

#

basically mimicing human behavior

primal steeple Mar 3, 2024, 4:46 PM

#

100% should work

zinc flame Mar 3, 2024, 4:46 PM

#

yep hopefully

primal steeple Mar 3, 2024, 4:46 PM

#

Guessing you want to make an afk farmer

zinc flame Mar 3, 2024, 4:46 PM

#

yes

primal steeple Mar 3, 2024, 4:46 PM

#

yeah

#

you can take screenshots using the hwnd too

zinc flame Mar 3, 2024, 4:47 PM

#

im already doing object detection xd

#

using hsv and opencv

#

but now im getting to the part where i need to press keys

primal steeple Mar 3, 2024, 4:48 PM

#

do you want it to work while not having the window open

#

or that doesn't matter

zinc flame Mar 3, 2024, 4:48 PM

#

i want the window to be in the background

primal steeple Mar 3, 2024, 4:48 PM

#

yeah this is the only way i guess

zinc flame Mar 3, 2024, 4:48 PM

#

postmessage or keybd_event?

primal steeple Mar 3, 2024, 4:49 PM

#

post message i reckon if the emulator isn't using raw mouse

zinc flame Mar 3, 2024, 4:49 PM

#

i mean its working

#

its just not holding it down but instead letting go and holding again

#

which is not ideal

bright ferryBOT Mar 3, 2024, 4:49 PM

#

@zinc flame has reached level 2. GG!

zinc flame Mar 3, 2024, 4:50 PM

#

i dont think ill be able to use keybd_event since it doesnt support windows in the background

primal steeple Mar 3, 2024, 4:51 PM

#

postmessage is the only way i can think of that's easy

zinc flame Mar 3, 2024, 4:51 PM

#

yep

#

what code would you use to hold down a key?

#

HWND hwndChild = GetWindow(hWND, GW_CHILD);
    WIN32::SendMessage(hwndChild, WM_ACTIVATE, WA_CLICKACTIVE, 0);
     PostMessage(hwndChild, WM_KEYDOWN, 0x44, 0);
    std::this_thread::sleep_for(std::chrono::milliseconds(1500));
    PostMessage(hwndChild, WM_KEYUP, 0x44, 0);``` would this not work?

#

the key should be held down for 1.5 seconds right

primal steeple Mar 3, 2024, 4:55 PM

#

No clue test it

zinc flame Mar 3, 2024, 4:55 PM

#

alright

gloomy cloak Mar 3, 2024, 5:37 PM

#

zinc flame ```c++ HWND hwndChild = GetWindow(hWND, GW_CHILD); WIN32::SendMessage(hwndCh...

maybe they are filtering for simulated input or doesnt even record it

zinc flame Mar 3, 2024, 5:37 PM

#

no cant be that because i tried it on notepad too

#

presses d then waits out the sleep and presses d again

gloomy cloak Mar 3, 2024, 5:39 PM

#

zinc flame no cant be that because i tried it on notepad too

oh yea bcs notepad is the exact same program as the game

zinc flame Mar 3, 2024, 5:39 PM

#

what i mean is that its not the app/game

#

ive tested it on multiple programs and its the same result

gloomy cloak Mar 3, 2024, 5:42 PM

#

zinc flame what i mean is that its not the app/game

just send normal inputs

#

with sendinput

zinc flame Mar 3, 2024, 5:42 PM

#

trying to send the input to a background window tho

gloomy cloak Mar 3, 2024, 5:42 PM

#

why that ?

zinc flame Mar 3, 2024, 5:42 PM

#

so i can use my pc to do other things while the program runs

gloomy cloak Mar 3, 2024, 5:43 PM

#

so its just a anti afk ?

zinc flame Mar 3, 2024, 5:43 PM

#

no i mean with sendinput the window has to be the active one

#

if i want to play or watch something else for example the program couldnt run

gloomy cloak Mar 3, 2024, 5:44 PM

#

and whats the logic behind that ? XD

#

bcs thats completly useless what u do

zinc flame Mar 3, 2024, 5:44 PM

#

i want to automate the game is the logic

gloomy cloak Mar 3, 2024, 5:44 PM

#

ahhh

zinc flame Mar 3, 2024, 5:44 PM

#

yea

gloomy cloak Mar 3, 2024, 5:46 PM

#

ig the game has no anticheat why dont u just go internal and yea call ingame functions to do stuff and there you also could do better checks etc

zinc flame Mar 3, 2024, 5:46 PM

#

its a phone game on an emulator

#

that would require me to be able to learn reverse engineering

gloomy cloak Mar 3, 2024, 5:47 PM

#

zinc flame its a phone game on an emulator

huh isnt the game available as pc game ?

zinc flame Mar 3, 2024, 5:47 PM

#

brawl stars is phone only atm

gloomy cloak Mar 3, 2024, 5:49 PM

#

mhhhhhhhhhh

primal steeple Mar 3, 2024, 6:02 PM

#

gloomy cloak oh yea bcs notepad is the exact same program as the game

it's an emulator so probably not

zinc flame Mar 3, 2024, 6:03 PM

#

i guess i was doing something wrong

#

Or the emulator was

#

After switching from LDPlayer to BlueStacks it now works somehow

#

¯_(ツ)_/¯

primal steeple Mar 3, 2024, 6:04 PM

#

raw mouse input then

zinc flame Mar 3, 2024, 6:04 PM

#

How does that work

primal steeple Mar 3, 2024, 6:05 PM

#

google

zinc flame Mar 3, 2024, 6:06 PM

#

ah i see

spring knot Mar 3, 2024, 6:20 PM

#

@zinc flame no reason to switch to c++

#

should be fine using it in python

zinc flame Mar 3, 2024, 6:21 PM

#

yeah but i really dislike python

bright ferryBOT Mar 3, 2024, 6:21 PM

#

@zinc flame has reached level 3. GG!

zinc flame Mar 3, 2024, 6:21 PM

#

i also want to learn more about c++

spring knot Mar 3, 2024, 6:24 PM

#

fair enough ig
