The system in those screenshots was clearly from before the IsoSurvivor system was written off, but after the map change, and the major ui overhaul. This would have been a test version, and these specific screenshots are from Lemmy (If you couldn't already tell by the behavior debug menus).
So I'm sure we all know that there have been test builds before with NPCs in them, and more specifically, before the old NPC system was abandoned. The ones I'm talking about are the ones that were never released further than internal testing. I was reading some old mondoid stuff, and I came across these pictures; http://projectzomboid.com/blog/wp-content/uploads/2015/01/npcs1.jpg http://projectzomboid.com/blog/wp-content/uploads/2015/03/npcs.png
I know these systems were completely abandoned, and I'm fine with that; However, I want to know if we ever get access to these old test builds. Those debuggers look like toys and I want to play with them. I know those old builds were probably totally broken and lack a ton of features we now have, but I just want to know if I will ever get the chance to play with those old NPCs and maybe create my own basic behavior trees with those debug menus.
