Reply To: [Bug] The "Clear List" ActionTask can cause Blackboard problems…

Hm, I see, I see.

I was thinking there was an algorithm where you could walk through all usages of that BBParameter and find its strictest possible type that everyone else could use.

EG,

1 2 3 4 5

BBParameter<IList> BBParameter<IEnumerable> BBParameter<List<GameObject>>

So IList would be added to the Blackboard first. Since IList implements IEnumerable, we can keep IList. And, since List<GameObject> implements IList, we’d upgrade to List<GameObject>.

At some point (probably due to operator error changing types) this algorithm breaks down… I think its okay to log a warning message and default to whatever the last variable type was.

But I haven’t really thought through this algorithm.
