Attempting to make a Python auto clicker - Stack Overflow

I am attempting to make an autoclicker that checks first if the clicker is enabled then if a user is holding down the left mouse button. If the conditions are met, the program would click with a range of delays. The auto clicking should stop once the user releases the left mouse button. The code I currently have is enabling and disabling fine but when I hold down my mouse button I get 1-2 clicks and then it just stops.

Second issue I have is when using the auto clicker's hotkeys is I have to not be pressing any additional keys to for the hot key to activate. So for example while playing a game I am unable to move around and provide other inputs enableing or disabling the auto clicker.

If anyone has any fixes for either of these issues I would greatly appreciate any input.

# Constants for Windows API mouse events
MOUSEEVENTF_LEFTDOWN = 0x0002
MOUSEEVENTF_LEFTUP = 0x0004

# Windows API functions
user32 = ctypes.windll.user32

def click():
    user32.mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
    user32.mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)

def is_left_mouse_button_pressed():
    return user32.GetAsyncKeyState(VK_LBUTTON) & 0x8000 != 0

# Control variables

# Hotkeys
ENABLE_KEY = 'g'  # Press 'g' to enable/disable auto-clicking
EXIT_KEY = '0'    # Press '0' to exit

def clicker():
    while True:
        if enabled:  # Only continue clicking if enabled
            while is_left_mouse_button_pressed():  # Check if the left mouse button is pressed
                click()
                time.sleep(random.uniform(0.05, 0.3))  # Randomized delay between clicks
            time.sleep(0.01)  # Short delay to prevent high CPU usage when left-click is not held
        else:
            time.sleep(0.01)  # Sleep to prevent high CPU usage when disabled

def toggle_clicking():
    global enabled
    enabled = not enabled  # Toggle state
    print(f"Auto-clicker {'enabled' if enabled else 'disabled'}")

# Start clicking thread
clicking_thread = threading.Thread(target=clicker, daemon=True)
clicking_thread.start()

# Set up hotkeys
keyboard.add_hotkey(ENABLE_KEY, toggle_clicking, suppress=False)  # Press 'g' to toggle auto-clicking

# Wait for exit key

• The user's click might be interfering with the program's click. Maybe try checking if a key is pressed instead – user5127 Commented Mar 13 at 5:25

Problem is that you attempt to build a self-sustaining solution, where a left mouse click shall induce lots of left mouse clicks. Whenever you produce a user32.mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0) , however, your condition is_left_mouse_button_pressed() gets false and thus exits the while-loop.

Quick fix that works for me is just changing the order of button up and button down events (as the mouse button is already down you leave the click()-method with the button in the same state).

clicks = 0  # Counter for the number of clicks

def click():
    global clicks
    clicks += 1
    user32.mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)
    print(f"Click {clicks}")
    user32.mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)

Another solution is to use a different trigger, e.g. the right mouse button or a key to control the auto clicking.

For the second issue, the problem is that keyboard is very specific with the hotkeys. To check the state of your hotkey, even with any other modifiers or keys pressed, you can introduce another thread that explicitly listens for those key presses:

def check_key_press():
    global enabled
    while True:
        if user32.GetAsyncKeyState(ord(ENABLE_KEY.upper())) & 0x8000:
            enabled = not enabled
            print(f"Auto-clicker {'enabled' if enabled else 'disabled'}")
            time.sleep(0.5)

Happy gaming!
