Custom decorator will not abort

Hi,

I’m using a custom decorator in a behavior tree that simply checks the value of a bool. I want the sub tree to abort if that value changes to true but it doesn’t seem to be working. The option to notify observers isn’t present in the options for the custom decorator.

I’m setting the blackboard value in C++ code if that makes any difference. I’m happy to implement my decorators in C++ as well if necessary.

I’m using the 4.8 preview built from source.

Ok, I seem to of fixed this by creating a C++ decorator that extends UBTDecorator_BlackboardBase instead.
