First of all thanks for so many responses,it means a lot to me.
I will really really try to avoid to call notify for each changed value in the HUD,because i have more to count health,stamina,ammo type,ammo left etc(and im planning to add more that will change the layout of the HUD,ex for one type of weapon add another bar). Also my character class is in c++ and i don’t know how to do it in blueprints. Is there any way that I can get the current character from the HUD on client side? I’ve tried to made the Controller class to keep the instance of the PlayerCharacter but that didnt work also since the controller get index 0 also returns null.
