When in your project, open your own PlayerController.
Next add the BPI_PlayerStats interface in Class Settings.
Also add the BPAC_PlayerStatsComponent to your PlayerController.
When this is done we want to on If(IsLocalPlayerController) Create the Main Stats widget and set it in the BPAC_PlayerStatsComponent. (this is done in your own playercontroller)
(You can copy paste this code from the BP_PlayerStatsExampleController into your own controller)
In the added GetStatsComp Interface function get the BPAC_PlayerStatsComponent and return it. Also in the IncreaseValue Interface function hook up the BPAC_PlayerStatsComponent Increase Value function.
These functions can be found on the left hand side of your player controller and player pawn where you added the BPI_PlayerStats.
This is everything you are required to do. 😄
