Right now the ‘Blackboard’ Decorator crashes if you attempt to add an Enum to it so I have to create a custom decorate to do this for me.
If would be good if the ‘Blackboard’ Decorator itself was expanded so that the options you wish to check for in the Decorator are tailored to the type of Variable you are checking and I see this being a common problem considering that many people will be using Enums to define AI states and checking against them on a regular basis.
