How To Quit ZBrush From ZScript?

ZScripting Help
#1

I can get the Close ‘x’ box to activate which brings up the save or not dialog box but I can’t hit the ‘n’ button to finish the process, from a ZScript:

[IButton,Play,“Press to play this ZScript. ZScript can be aborted at anytime by pressing the ëescí key.”,
[IConfig,4.8]
[IPress,Close]
[Delay,3]
[IKeyPress,“n”]
]/End of ZScript/

The Delay doesn’t help. The key press doesn’t seem to happen, to not save, and thus finish quitting.

I need to quit since I’m invoking ZBrush from a Python script from another program (Rhino Grasshopper) but my Python subprocess needs to know the process is done and over or it freezes up and I have to manually quit ZBrush.

[This may be a blessing in disguise since it’s slow to keep restarting and quitting ZBrush and I may be able to communicate in some other way with my Python script if I can figure out how to get it to launch ZBrush with a ZScript and then not just freeze up, but say, check every second if a file has been modified, or something.]

You need to use uppercase “N” and wrap the IKeyPress around the [IPress,Close]. You can use the ASCII code 78 instead of “N” but both work:

[IButton,Play,“Close ZBrush without saving project”,
[IConfig,4.8]
[IKeyPress,78,[IPress,Close]]
]/End of ZScript/

Also, if you are launching ZBrush from python with a zscript then you need to make sure the zscript will run automatically by wrapping the second level commands inside an [If,1,] statement (that is always true).

Formatting issue, I see.

I’ve figured out how to not have ZBrush freeze up my Python program by using subprocess.Popen() instead of subprocess.call() and then using a time.sleep() while loop to wait until the output file can be opened for appending. So I don’t have to quit ZBrush any more.

However, I still have to learn to then return focus to my Python program in Windows. The ZBrush Hide button fails most of the time, even manually, unless I first use Restore, but even then it’s not reliable. It may have to do with being opened initially in a subprocess of another program.

This seems to work from Python, to put ZBrush back in hiding:

import ctypes
zbrush_handle = ctypes.windll.user32.FindWindowW(u"ZBrush", None)
ctypes.windll.user32.ShowWindow(zbrush_handle, 6)

Not exactly. Lowercase “n” will not work.
