That’s actually super cool you can run 2 at the same time. Can they share a blackboard? So one can affect others decorators?
I understand there are methods to run BT inside a BT, or parallel tasks, but having multiple separate trees unlinked but using the same blackboard would mean you can swap completely behavior of an actor extremely fast by switching off one tree and turning on another.
With what is described in official documentation you can achieve similar results, but having more dependencies and harder time to swap parts of behaviour.
For example a sims-like the character could have a BT that drives it needs like eating drinking and sleeping… while another example of ai would not need any of those, but still run same movement logic.
Unless I am missing something? I am preparing to make an AI tutorial and don’t want to build it on false assumptions.
