The AutoIt MouseClick function is used to automate the mouse and send mouse clicks. The way it works is by moving the mouse to the given screen coordinates, at a given speed, and then perform the number of clicks asked of it, with the given mouse button.

There is a tool that comes with AutoIt called Window Info which can be used to get the coordinates of the screen.

If the AutoIt Window Info tool is used to get the screen coordinates which are to be clicked, the coord mode setting of the tool will influence the returned pixel coords. This can sometimes cause scripts to click in unexpected coordinates. To avoid this, be sure to set the MouseCoordMode option in your scripts so that it matches the Coord Mode setting in the Window Info tool. I.e.

Opt("MouseCoordMode", 1) ; Sets the coord mode to use absolute screen coordinates

MouseClick("primary", 200, 150, 50)

The coord mode values are as follows:

0Coordinates relative to the active window
1Absolute screen coordinates (default)
2Coordinates relative to the client area of the active window


The MouseClick function accepts 4 Parameters, the first the button to click with, the second and third is the pixel based left and right position on the screen, while the final value to be given is the movement speed of the mouse.

left || right || middle || main || menu || primary || secondary The mouse button to be clicked.
pixels The (x) position from the left in pixels.
pixels The (y) position from the top in pixels.
1-100 The movement speed of the mouse, takes a value from 1 to 100.

Some users change their primary mouse button from left to right, so if you want to be sure that the button you intend is used, you may want to use the primary and secondary settings.

AutoIt MouseClick examples

The first example only uses the MouseClick function to perform a one time click on the supplied screen coordinates. If the pointer is not already at the location, the pointer will automatically move there with a speed of 50 (the last function parameter).

MouseClick("primary", 200, 150, 50)

In the second example, the script will repeatedly click the same spot on a screen until an exit hotkey is pressed. To accomplish this, we can place the MouseClick function inside a while loop. I.e.

;Assigns the HotKey to our custom exit function
HotKeySet("^!x", "MyExit")

; The coordinates to click in pixels
$x = 200
$y = 150

$i = 0
While $i <= 10
  MouseClick("left", $x, $y, 1)

  ; Uncomment the below line to make the script click only 10 times, or until the hotkey is pressed.
   ; $i = $i + 1
  ; Uncomment the below line to make the script pause between clicks, the value is in milliseconds
   ; Sleep(5000)

Func MyExit()

The above script consists of two important parts, the first being the Infinite loop, which can only be stopped with the hotkey that we set in the beginning of the script using the HotKeySet function. The second part is the function at the end of the script, defined using the Func statement, which we bound to our hotkey at the beginning of the script. See also: User functions
