Simple transparency toggle with Autohotkey

Question

Hopefully a simple question with an equally simple answer...

I'm trying to make an autohotkey script to toggle window transparency.

Currently, I'm setting the active window transparency with the following:

^!RButton::WinSet, Transparent, 150, A

However, I'd like to extend this to toggle between 150 and 255, but am having a difficult time grasping how to toggle this.

Edit: By toggle, I'm meaning hit Ctrl+Alt+Right Mouse Button once to set the transparency to 150, and then hitting it again to set the window back to full transparency.

Answer 1

Something like this would probably do it (untested):

^!RButton::
WinGet, currentTransparency, Transparent, A
if (currentTransparency = 150)
{
    WinSet, Transparent, 255, A
}
else
{
    WinSet, Transparent, 150, A
}
return
