How do I make an auto clicker that clicks in a specific game?

For example, I tick the checkbox and then it will start clicking. It will only click in the came it was specified to (pretend it's Combat Arms). So if you move the mouse out onto the desktop or anywhere else, it won't click. When you move the mouse back in the game, it will click.

Thank you in advance

Well, keybd_event() and sendinput() and mouse_event() are all patched on such fps games. The only way is to hook the game, which i don't have much experience in, so i will let the more knowledgeable people answer you.

Just bind the clicking to a key, use for loop and inside that a while loop that loops while the key is pressed
