How Can I instantiate a box trigger from Blueprint?

The c++ script is that the only option i can instantiate an actor or i can also do it on Blueprint ?<

What trigger box is it’s empty actor with box component, you can use box component (or other shape components) on any actor and then use overlap events on that actor.

For example, when my player kill all enemies of the level, an special object (like a treasure) shows up. I can easily do that in Unity. In Unreal it is kind of hard for me. How to do it ?

Use Box Component on treasure actor

I finally found another to do it. I also accepted that the Unreal philosophy is completly different than the Unity philosophy.
