; 把操纵杆作为鼠标使用
; https://www.autohotkey.com
; 此脚本把操纵杆转换为三键的鼠标.
; 它允许每个按钮像鼠标按钮那样拖动,且它几乎不消耗 CPU 时间.
; 还有, 您将操纵杆推离中央越远, 它会让光标移动的越快.
; 您可以在脚本的顶部个性化各种设置.

; Increase the following value to make the mouse cursor move faster:
JoyMultiplier = 0.30

; Decrease the following value to require less joystick displacement-from-center
; to start moving the mouse.  However, you may need to calibrate your joystick
; -- ensuring it's properly centered -- to avoid cursor drift. A perfectly tight
; and centered joystick could use a value of 1:
JoyThreshold = 3

; Change the following to true to invert the Y-axis, which causes the mouse to
; move vertically in the direction opposite the stick:
InvertYAxis := false

; Change these values to use joystick button numbers other than 1, 2, and 3 for
; the left, right, and middle mouse buttons.  Available numbers are 1 through 32.
; Use the Joystick Test Script to find out your joystick's numbers more easily.
ButtonLeft = 1
ButtonRight = 2
ButtonMiddle = 3

; If your joystick has a POV control, you can use it as a mouse wheel.  The
; following value is the number of milliseconds between turns of the wheel.
; Decrease it to have the wheel turn faster:
WheelDelay = 250

; If your system has more than one joystick, increase this value to use a joystick
; other than the first:
JoystickNumber = 1

; END OF CONFIG SECTION -- Don't change anything below this point unless you want
; to alter the basic nature of the script.
