Some applications don't respond to win32gui clicks-CodePudding

Background: I was trying to program an auto clicker to click in the background to an application (Roblox, not trying to do anything malicious). I was able to get the window and perform commands like closing it. However, when trying to send clicks to the window it returns 0. (I'm using SendMessage so I don't activate the window)

Minimum reproducible example:

import win32gui
import win32con
import win32api


hwnd = win32gui.FindWindow(None, "Roblox")


while True:
    lParam = win32api.MAKELONG(100, 100)
    temp = win32gui.SendMessage(hwnd, win32con.WM_LBUTTONDOWN, None, lParam)
    win32gui.SendMessage(hwnd, win32con.WM_LBUTTONUP, None, lParam)
    print(temp)

Things I tried:

I tried changing the window to see if it was the wrong window, or if it didn't see the window
I tried sending the message normally:

lParam = win32api.MAKELONG(100, 100)  # Get the coordinates and change to long
temp = win32gui.SendMessage(hwnd, win32con.WM_LBUTTONDOWN, None, lParam)  # Send message to handle
win32gui.SendMessage(hwnd, win32con.WM_LBUTTONUP, None, lParam)  # Release key from sent message to handle

I tried it with other windows, and it worked, but not for Roblox
I tried with other commands and it works, but clicks don't. This works: (So I know it's the right window)

temp = win32gui.SendMessage(hwnd, win32con.WM_CLOSE, 0, 0)  # Close window with SendMessage

CodePudding user response：

All roblox games will allow manual clicks. However, some games may deny the signals as it may give the players unfair advantages over other players. I, as a lua developer myself, stop players from autoclicking as it will ruin the whole point of my tycoon.

Some Roblox games prevent auto clicking.
