Dont worry about the questions..That’s what the forums is for 🙂
The correct way after version 1.5.3 is to use [BlackboardOnly]
Prior to 1.5.3 the way was to initialize the BBVariable with {blackboardOnly = true}. I just have’t changed all actions to the new way.
The useBlackboard is different. It is whether or not the BBVariable ‘currently’ is set to use the blackbaord (radio button pressed)
I just initialize some of them to start with that button pressed for convenience, that’s all.
So, to recap, the way it’s [BlackboardOnly] attribute 🙂
