My team mate works with pure blueprints, while I work mostly with C++ and am not very familiar with blueprints. Im trying to access an ActorComponent on one of the actors, but Im not sure how to find the C++ class equivalent of the ActorComponent.
The C++ version of the ActorComponent is UActorComponent.
However, what I think you might be asking is how to get a blueprint-derived child of ActorComponent. Which is a far more difficult problem to solve with no real documentation. You’re better off moving that class to C++ (or some base form of it)
You can use LoadClass function and give it path of that BP and create object on runtime
