Save Mouse coord and re-use it

[Ousapik]

Hello,

I want to use mouse coord and click or drag at these coord when i want, but the mouse coord where i want to clic or drag change so i use a hotkey which store the position when it change.

I tried to make a script using MouseGetPos, MousClick and MouseClickDrag , draging or click at a fixed position i was successful but when i tried to hotkey a function to "save" the mouse position with MousegetPos, autoIt tell me "Variable used without being declared."

I tried these functions

Func Start()
    $StartPos = MouseGetPos()
EndFunc

Func Drag()
    $DragPos = MouseGetPos()
    MouseClickDrag("left", $DragPos[0], $DragPos[1], $StartPos[0], $StartPos[1], 0)
   
EndFunc

Func Click()
    
    MouseClick("left", [,$StartPos[0], $StartPos[1] [,1 [,0]]])

EndFunc

When i use the hotkey for Start i dont "save" the coords and i have an error.

Your script should declare global variable so the variables referenced by a function won't be assumed local variables.

Global $StartPos

; ...
; ..

Func Start()
    $StartPos = MouseGetPos()
EndFunc

Func Drag()
    $DragPos = MouseGetPos()
    
    If IsArray($StartPos) Then _
        MouseClickDrag("left", $DragPos[0], $DragPos[1], $StartPos[0], $StartPos[1], 0)
   
EndFunc

Func Click()
    
    MouseClick("left", [,$StartPos[0], $StartPos[1] [,1 [,0]]])

EndFunc

..this way the $DragPos is local but it only get referenced by the function defining it.
