I don't think the TerritoryComponent exists in the Behaviors module.

The closest thing we have is TerritoryDistance, a component with two fields distance and location.

Therefore, the referenced component should probably be

Suggested change
componentPresent: "Behaviours:Territory",
componentPresent: "Behaviours:TerritoryDistance",

and the referenced field below cannot be Territory (as it does not exist) but either distance or location. I suspect that we can check whether the location is set.

values: ["F Territory != null"],

This would try to make a lookup of a field (indicated by F) named null.

However, I believe you want to check against the value null, thus using V would be correct.

Suggested change
values: ["F Territory != null"],
values: ["V Territory != null"],

Alternatively, you can use the exists operator (basically ... != null) without an explicit value to check against:

Suggested change
values: ["F Territory != null"],
values: ["N Territory exists"],

With the comment above about the component, this should most likely be

We discussed this in the meeting today.

The N is a parsing directive that specifiies whether the condition has the form type fieldName operator or type fieldName operator valueOrReference.

Technically, we could use V charactersWithinRange != null to ensure that the list itself is defined and not null (checking agains the value null). However, this is not the semantics we are looking for.

Therefore, using the nonEmpty operator on the collection with no value to check against (N) is the solution:

Suggested change
values: ["N charactersWithinRange != null"], // Adjust for Nemesis / Scary Creatures
values: ["N charactersWithinRange nonEmpty"], // Adjust for Nemesis / Scary Creatures


child: {
sequence: [
{
"lookup": {
"tree": "scaredCritter.behavior"
