You can setup your collision in a way that only x type of objects can trigger the overlap event, but either way, you’ll have to use casting anyways. Bind a function to the box collision component’s begin overlap event, and cast OtherActor into the desired class.

Event Binding in UE4 c++



AMyCustomActor* MyCustomActor = Cast<AMyCustomActor>(OtherActor);
if (MyCustomActor)
{
     // ...
}

thanks dude! I decided to move my blueprints to c++. Do I have to declare first the function? or just put that lines in the .cpp?

Declare functions in .h and implement them in .cpp
