Using B2SwindowPunch for a overlay clock in DMD

[guenni_d]

Hi, 

Sometimes I lose track of time when playing pinball, which is why I wanted to add a small clock overlay to the backglass or the DMD.
I installed a small overlay clock app for this purpose. However, it only appears as an overlay in the PinUp Popper. So I thought I’d sort this out using B2SWindowpunch and added a suitable command to the last line of B2SInit.cmd. This works when I run it manually via cmd, but not via B2SInit.cmd 

The command is:

"B2SWindowpunch" "^B2S DMD$" "OverlayClock"
 

 

Whats wrong with my line?

Hi Günter,

 

please check the B2S wiki for the full documentation:  https://github.com/vpinball/b2s-backglass/wiki/B2SWindowPunch#advanced-users

 

You call it through the command:

B2SWindowPunch.exe "^B2S Backglass$|^B2S Backglass Server$|^B2S DMD$" "^Virtual DMD$|^Virtual Alphanumeric Display$|^PUPSCREEN[0-9]+$"

 

which means

 

B2SWindowPunch.exe "The window(s) where to cut in" "The window(s) to cut with"

So what happens, is that B2SWindowPunch checks for any window titles which fit the first parameter and those who fit the second parameter, and where it is a match and the windows overlap, it will punch a hole...
