I have been looking at some State menu code from sfml game development book and other game source code. I was wonder if my game state code will work if implemented in a game? i created a state and gamestate header files with their cpp files. I been trying to practice on my own rather than just copy and past code from other source code so if I did something wrong or wrote code in a bad way please point it out and tell me how to write it better or if i need to remove some functions or add functions to a header file or just write the whole thing over again. Thank you

. I should have checked it. Also, how do make headers files appear as a .hpp? In my visual studious all i see when creating a new header file is .h . What do you mean use tags next time so you dont have to insert them.
