General / SFML And Emulators?

« on: January 13, 2016, 03:11:50 pm »

Hey Guys!
I am looking to create a Gameboy emulator in C++ and need to choose a graphics library. Would SFML be able to work in an emulator or should I learn SDL?
Thanks!

Thanks for the opinions for DirectX. There may be a misunderstanding. I will be using Unity and GMS for actual games, but I wanna learn DX just for fun. I don't know why, it's just I saw a cool looking boook and I wanna try to make a emulator and a game engine one day on the far future. Also, I am in highschool and have taught myself everything, so I am not looking to make "real" indie games. Just side stuff. Thanks for the tips, though!

Oh! and BTW Nexus, I thought your SFML book was really cool. I got it for Christmas a couple years ago but never looked at it till I made this game.

SFML projects / My First SFML Game! A Game Like Space Invaders!

Hey Guys!
     I have been developing games for several years now with Unity 3D and GameMaker: Studio. However, in a burst of motivation, I decided to learn SFML and make a game in it. I am pretty new to OOP in C++, so the code is pretty rough . Although I enjoyed SFML, I am going to learn DirectX since that is largely applied in the AAA game industry from my understanding.

Here is the Git Repo

OK. I have just recently been diving into OOP stuff. I watch some more thenewboston. Thanks for the help. If I run into anymore problems with this, I'll just read docs and wath C++ videos. THANKS!

Sorry to keep hassling you.

So I read the documentation on sf::Drawable.

first I added:
#include <Drawable.hpp>

That gives me this error:
Severity   Code   Description   Project   File   Line
Error (active)      cannot open source file "Drawable.hpp"   SFML Test   c:\Users\Calvin\Documents\Visual Studio 2015\Projects\SFML Test\SFML Test\Source.cpp   4

The thing is, I have graphics.hpp imported, libs and include directories are set up, and I have set the linker options, for debug which I am in.

For the class I did this:

        //Creating an Enemy
        class Enemy : sf::Drawable
        {
        public:
        private:
                virtual void draw(sf::RenderTarget& target, sf::RenderStates states) const
                {
                        sf::RectangleShape enemyShape(sf::Vector2f(35, 15));
                        target.draw(enemyShape);
                }
        };

        Enemy enemy;

This doesn't cause any errors, but it also doesn't accomplish anything more.

Lastly, I added this at the end:

window.draw(enemy);
 

This causes this error:
Severity   Code   Description   Project   File   Line
Error (active)      conversion to inaccessible base class "sf::Drawable" is not allowed   SFML Test   c:\Users\Calvin\Documents\Visual Studio 2015\Projects\SFML Test\SFML Test\Source.cpp   70

and this:
Severity   Code   Description   Project   File   Line
Error   C2243   'type cast': conversion from 'main::Enemy *' to 'const sf::Drawable &' exists, but is inaccessible   SFML Test   c:\users\calvin\documents\visual studio 2015\projects\sfml test\sfml test\source.cpp   70

Once again, sorry if I'm plaguing your life. I looked at SFML a couple years ago and decided it was way to complicated, now, I'm ready to learn. Please let me know if I can give you any more info.

Thanks for the reply! Where is the documentation for what you are talking about?

General / Help With Space Invaders Style Game Class. Just started SFML.

Hey Guys!
I just recently started using SFML with C++ and I really enjoy it. However, because I'm new, I have already run into a problem. I am trying to recreate Space Invaders. To create the enemy, I assume my options are to create the enemy, and then copy and paste that code again and again. My other reasonable and cleaner option was to create a class. My problem is, I can't get my classes to work in SFML. Can someone help?

The first thing I do is create a class and then create an object:

        //Creating an Enemy
        class Enemy
        {
        public:
                Enemy::Enemy()
                {
                        sf::RectangleShape shape(sf::Vector2f(25, 25));
                }
        };
       
        Enemy enemyOne;

After that, I call the enemyOne object in the window.draw()

window.draw(enemyOne);

However I get the error:
Severity   Code   Description   Project   File   Line
Error   C2664   'void sf::RenderTarget::draw(const sf::Vertex *,size_t,sf::PrimitiveType,const sf::RenderStates &)': cannot convert argument 1 from 'main::Enemy' to 'const sf::Drawable &'   SFML Test   c:\users\calvin\documents\visual studio 2015\projects\sfml test\sfml test\source.cpp   71

and I get this error:
Severity   Code   Description   Project   File   Line
Error (active)      no instance of overloaded function "sf::RenderWindow::draw" matches the argument list   SFML Test   c:\Users\Calvin\Documents\Visual Studio 2015\Projects\SFML Test\SFML Test\Source.cpp   71

What am I doing wrong and how can I fix it?

Any help would be GREATLY appreciated. I have been making games with game engines (Unity, GM, etc.) and really want to start using SFML.
