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

Hey,
Thanks for the elaboration and your suggestion. It overally makes sense I think, but I need to think a bit more about this 🙂
I did make some tests you can also try out. If you want, please open up BlackboardSource.cs file and change the first clause in the AddVariable method in line #80 to be like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

if ( variables.ContainsKey(varName) ) {                 var existing = GetVariable(varName);                 if ( existing != null ) {                     if ( existing.CanConvertTo(type) ) {                         Debug.LogWarning(string.Format("<b>Blackboard:</b> Variable with name '{0}' already exists in blackboard '{1}'. Returning existing instead of new.", varName, this.name));                         return existing;                     }                     if ( existing.CanConvertFrom(type) ) {                         Debug.LogWarning(string.Format("<b>Blackboard:</b> Variable with name '{0}' already exists in blackboard '{1}' but is of assignable type. Upgrading type and returning new variable.", varName, this.name));                         RemoveVariable(varName);                     }                 }             }

This is just a test and not meant to really be used however 🙂 It does handle the specific case you showcased, but I will need to see what other kind of problems this may create.

Let me know what you think if you do test it.
Thank you!
