Just to clarify.
void Subscreen
is Passive subscreen scripting right?
Wouldn't it be funny if the subscreen had a different game running like MoM program on the pause menu that could be done there like this?
Thoughts?
Pause Screen Scripts
To script a subscreen you'll want either a generic, subscreendata, or subscreen dmap script. Generic and subscreen dmapdata both run in their own frozen state like what you're describing, while a subscreendata script will let you interact with widgets on an engine subscreen.
Not sure what this void Subscreen you're seeing is but I'd hazard a guess it's part of a much older form of scripted subscreen that did not have access to these features.
For an example of a quest running an entire different game on the subscreen, check out Barato by Aslion.
