How can I setup SFML in Visual Studio 2017? - c++

Question

I don't know if this has happened to some of you guys. I haven't started programming because "I don't know where to start". I want to make a platform video game, and 8 bits one. Yeah it will take a lot of time and skill, but I always like to jump to the complicated stuff.
I'm the kind of person that likes to use the latest of the latest programs. So I use Visual Studio 2017, however SFML is up to VS2015. Is there a way to use SFML is VS2017? What can I do?

Answer 1

First, congrats on starting your journey into programming!
However, as someone who has tutored many kids who have the same ambition (e.g. learning C++ to make a video game), I'd recommend you start down a simpler path.
I won't go into trying to learn C# or Java or some other language, as I, and many others, actually started with C; it's not about learning the particular language, it's about understanding the system as a whole. The concept of a thread, object, loops or functions doesn't change, it's how it's utilized that changes between languages.

While this might typically be good for most programs, due to bug fixes or other enhancements, this is not true for development environments. When you update Visual Studio, you're typically updating your entire toolchain: compiler, linker, SDK's, etc.
This means the possibility to introduce either a buggy compiler, or have code flagged as deprecated, among other issues to be considered. Especially when developing something like a game.

Here's a simple "war" card game that emulates 2 players; it automatically plays war until the game is won. It repeats this until an interrupt signal is received (CTRL+C) and it prints out the maximum number of turns during any game, as well as the minimum number of turns in any game played by our 'auto-players'.
It's in C++, can be modified to take user input for a blackjack or poker game, and you can build it on any system simply enough.
This code is meant for teaching, so you can take this code, modify it, build it, run it, and understand what's happening in each of those steps.
From there, you can learn more, ask more questions, and eventually you'll be able to make your 2D platform game with SFML.

Just a note to say SFML now works fine with VS2017.
I have version 2.5 binaries no need to compile.
See instructions here:
https://www.sfml-dev.org/tutorials/2.5/start-vc.php
