Remap mouse-event to keyboard key

Question

I want to remap mouse-up and mouse-down to keyboard keys, but only while using a certain application. This is how far I got:

_WinWaitActivate("League of Legends (TM) Client", "")
HotKeySet("{K}", "WinTab")
ProcessWait("")

Func WinTab()
    Send("G")
EndFunc

#region --- Internal functions Au3Recorder Start ---
Func _WinWaitActivate($title, $text, $timeout=0)
    WinWait($title, $text, $timeout)
    If Not WinActive($title, $text) Then WinActivate($title, $text)
    WinWaitActive($title, $text, $timeout)
EndFunc
#endregion --- Internal functions Au3Recorder End ---

This would remap K to G. It's possible to remap the mouse wheel as well, but I could not find the appropriate keybinding. I also want to pause the remapping if Esc is pressed or Alt + Tab for example.

Answer 1

You cannot bind mouse actions using HotKeySet, as that is only for keyboards.

Instead there are several options:

• Check for mouse actions in a loop (using _IsPressed). This has been done before in both simple forms and more complex.
• Use the Windows API and a mouse hook (or a low level mouse hook depending on what you need to do). Search the AutoIt forums for examples of how to use this.
• Use MrCreatoR's MouseSetOnEvent UDF

The second part has been done thousands of times... Search for it :)

Answer 2

Use:

While True
    If IsPressed('21') Then
        MouseWheel("up", 2)
    EndIf

    If IsPressed('22') Then
        MouseWheel("down", 2)
    EndIf
    Sleep(100)
Wend

Exit

Func IsPressed($hexKey)
    Local $aR, $bO
    $hexKey = '0x' & $hexKey
    $aR = DllCall("user32", "int", "GetAsyncKeyState", "int", $hexKey)
    If Not @error And BitAND($aR[0], 0x8000) = 0x8000 Then
        $bO = 1
    Else
        $bO = 0
    EndIf
    Return $bO
EndFunc  ;==>_IsPressed
