Local $user32 = DllOpen("user32.dll")
        DllCall($user32, "int", "PostMessage", "hwnd", $hWnd, "int", 0x200, "int", 0, "long", 547, 400)
        DllCall($user32, "int", "PostMessage", "hwnd", $hWnd, "int", 0x201, "int", 0, "long", 547, 400)
        DllCall($user32, "int", "PostMessage", "hwnd", $hWnd, "int", 0x202, "int", 0, "long", 547, 400)
         


ps:$hWnd = WinGetHandle("ETQW")//"ETQW"是一款古老的射击游戏窗口。


我把游戏窗口的句柄换成au3的窗口又可以实现鼠标点击，但是切换到游戏的窗口以后就无法移动鼠标
