Return a value from a BlueprintImplementableEvent [Solved]

I have a function I need to implement in blueprints that I would like to be able to get back a boolen from. What I am trying to do is basically:

UFUNCTION(BlueprintImplementableEvent)
bool MyFunction(bool param1);

However, BlueprintImplementableEvents cannot have a return value.

I’ve tried adding another UPROPERTY to write the output to which works, but I haven’t found any way to set the UPROPERTY to essentially be private and only accessible to the owning class/blueprint.

I’ve tried turning param1 into bool& to see if I could write back into the parameter, but then the event no longer shows up in the editor.

I’ve also tried turning param1 into bool* which leads to a compiler error.

Finally, Return a value from a BlueprintImplementableEvent - Programming & Scripting / Blueprint - Epic Developer Community Forums seems to be exactly what I am looking for and very commonly linked to, but the post with the answer seems to have been deleted.

Is there a method to return a value from a BlueprintImplementableEvent?

Edit: I converted it to a BlueprintNativeEvent

Try this.

UFUNCTION(BlueprintImplementableEvent, Category = "Foo", meta = (ForceAsFunction))
bool MyFunction(bool param1);

I like that a lot better than having the empty _implementation.

Thank you.
