Cant access to BP variables

Hi.
Why iam unable to access to my Character’s BP variables, while i can access to its components (like mesh or collisions)?

Can someone explain?

Heres the example pic.

Get player character (index) returns a reference to the base “character” class, Not your modified inherited class.

You have to cast to the class to get access to the “new” functions, variables, events, components etc.
