C++ SFML

Question

Trying to sort out a game engine/state machine using enum class. Can't seem to figure it out, I've looked all over the internet btw.

Answer 1

are you facing linker's problem?!
if yes so tell me about your environment and ide ....
leme know it first..

Answer 2

I understand how enum works, I'm just lost at how to work the different levels/menu stuff into it. I know I can create headers and cpp files but I just can't order it or figure how to link it to work

Answer 3

No, I understand the enum itself
But where would I declare my game states and how would I link that to my enum class header
For example atm I have a menu, a main game and a win page as functions. This is messy and doesn't work if I try to loop back to main. How can I make these into a game engine linked to enum

Answer 4

Yes except for me wanting to loop win screen to menu

Answer 5

It runs fine in main, but I can't make win screen go to menu screen because of the order of the functions. In a state machine/game engine you should be able to create whatever whenever but I don't know how to create and link it in to the enum class

Answer 6

I can't because win has to be above main and main has to be above menu

Answer 7

When I said main I meant main game func.
I currently have all 3 states in separate functions. I want to create a state machine/game engine with enum controlling which screen I'm on, game/menu/win ect.
I'm using SFML in Visual Studio 2019

Answer 8

I’m not sure about what you’re trying to do here.

let’s take an example of
enum go {east, south, west, north}

to create a state machine, just create a vector of go

vector<go> dir = {east, east, west, north};
//prints 0 0 2 3

is that what you’re looking for?

Answer 9

Again, not sure what you’re asking about

declare enum in header.h
include header.h in main.cpp
access enum from main

does this answer your question?

Answer 10

before you split the functions and classes into multiple header files, does it work with single main.cpp?

Answer 11

I never made a game myself, so I have very little idea of what you’re talking about

but if it doesn’t work in a single main.cpp, then why do you think splitting them will make it work

I think there might be something wrong with your game logic

Answer 12

if you have a function that shows menu screen, let’s call it menu()

what happens when you call menu() after win screen appears

forget about enum class for a second

Answer 13

can you move menu to the top of main?
if not, why?
all functions should be declared before main()
this is the root of your problem, not linking multiple files

Answer 14

I have created a system of headers and c++ files that individually work. Except...I cant seem to find a way to switch between the states. I declared my enum in engine which includes header files to Game, Menu,Win. I have separate cpp files for input,draw,update that includes engine. Where and how could I conditionally switch states? Ideally I'd like game to switch to win when score=5 and win to switch to menu when button pressed. But where can I write this that would be able to access those variables.
