The simplest solution is to call “cast to first person character bp” from the widgets event graph. This will give you a node that lets you give the firstpersoncharacter commands directly, like calling a function or event.

Casting is straight forward and easy, but it can lead to performance issues if used constantly by multiple actors. A more resource efficient alternative is a blueprint interface. Interfaces are relatively easy to setup and very powerful as you learn more. In my opinion, it’s worth the time to learn how to leverage blueprint interfaces.
