Using Player State?

I don’t understand what you wanna mean with:

**Creating a player state blueprint is the same as creating any other blueprint class. Right click in the content browser > New Asset > Blueprint Class > All Classes > Player State.
if you name it Master_PlayerSate then you’ll have an option in any blueprint interface to do a cast to Master_PlayerState.
**

**
But player state blueprints are empty by default, so you’ll need to add your own variables. If you add one inside the blueprint called MyVariable then drag a pin out from your cast Master_PlayerState in your widget blueprint you’ll see options like Set MyVariable and Get MyVariable.
**

**
Also for network purposes be sure to set your GameMode to use Master_PlayerState as its player state class, and set the replication option on each variable in your player state to “Replicate”.**

I understand programming strategies, but don’t understand this in blueprint yet…
Can explain more about this??
