Hello everyone,
The “Blackboard Based Condition” decorator, has a way to change which variable is visible based on the blackboard keyselector.
Does anyone know how I can link the blackboard keyselector to the visibility of certain variables?
So If the blackboard keyselector was a boolean it would just show a bool.
For an integer an integer
For a float a float etc.
If anyone could help guide me with this I would appreciate it a lot 
Basically I want to have a variable like a boolean or so, and if thats true it will show more variables to modify, but if that bool is set to false then it will not show these options.
I have not tested this and I believe it can only disable properties (not hide), but I know of a metadata specifier " EditCondition" as explained here:
Hey thanks for the reply,
Yea I think what you got there is actually the answer. I opened up one of the task from the behavior tree that actually have this feature:
Thanks for guiding me in the right direction
However my project is just blueprints as I have no idea how to use C++ properly. <.<
I guess there is no way to do it in a blueprint only project.
Ah right, I missed that it is BP only.
The specifier you show on the image is a class specifier, the property specifier I spoke about would look like this on a property:
UPROPERTY(EditAnywhere)
bool bShowPropertyCondition = true;
UPROPERTY(EditAnywhere, meta = (EditCondition="bShowPropertyCondition"))
int32 SomeProperty = 0;
where the EditCondition can be a boolean or expression.
I’m not sure if there is a property on a blueprint asset to specifiy additional metadata in? Else it’s c++ only.
For c++ users that want to actualy hide property not only disable it, there is meta “EditConditionHides” that must be used together with “EditCondition”, for some reason “EditConditionHides” is missing in Metadata Specifiers documentation.
