FAQ

Auto‑clicking doesn’t work in some games. Why?

Some games include anti‑cheat systems that block automated input. These systems may prevent cursor movement or auto‑clicking by detecting it as unauthorized behavior.

Additionally, games that rely on DirectInput or RawInput may not accept simulated clicks or cursor movement, which can also prevent auto‑clicking from functioning.

I want to auto‑click at a specific position, but auto‑clicking doesn’t start after the cursor moves.

When using “Auto‑Click While Button Is Held”, and you specify a click position:

1. Pressing the assigned button instantly moves the cursor to the target position.
2. Auto‑clicking begins only if the window under the cursor at the moment you press the button matches the window located at the target click position.

If these two windows differ, the cursor will move, but auto‑clicking may not start.

Solution

After the cursor moves to the specified position:

1. Release the button once,
2. Then press it again to start auto‑clicking properly.
