That's why i have about 5-6 abandoned projects

And you're already a good example of someone who *does* finish games. :-)

thank you

you can use new and delete to manage the order.

also why clang and libc++ isn't set as default in CMake? 

'Cause I haven't got around creating a PR for that. If you want to do it, your help is more than welcomed!

Sorry, i'm not familiar with Mac OS at all and i'm afraid to do something wrong.

And about the issue - may be if someone familiar with OpenGL debugging could get trace of my example with and without the line i specified - it possibly help with fixing that

have a look at the options presented in §C++11 and Mac OS X of https://www.sfml-dev.org/tutorials/2.4/compile-with-cmake.php.

thanks, that works 

but, unfortunately issue still exists and this branch didn't helped.

also why clang and libc++ isn't set as default in CMake?

I don't know what you mean by "precompile", but this error is most likely due to a mismatch in standard library used to compile your project and SFML. The nightly build are compiled with libstdc++ at the moment but the official release are compiled with libc++. Don't mix those two or you'll get such linker errors.

oh, sorry, not precompiled. i meant compiled binaries  how can i build it with libc++ instead of libstdc++?

PS: i guess i compile it with same standart libraries, because i do not specify it

make sure you're compiling your project and SFML with the same standard library.

but why I can compile 2.4.1 and it works. i can use precompiled 2.4.2, 2.4.1 and it works. but it fails if i use precompiled nightly build or compile that branch by myself?

Tried night build from here https://www.sfml-dev.org/artifacts/by-branch/bugfix/osx_render_target/
 got same linker error

I tried this patch on sfml 2.4.1 - it doesn't help, everything is the same.

I tried to compile branch bugfix/osx_render_target, but got this on compiling my project (i had no such issue with 2.4.1, that's why tested this patch on this version)

Undefined symbols for architecture x86_64:
  "sf::String::String(char const*, std::__1::locale const&)", referenced from:
 

Used simple "cmake . && make" to compile.

Graphics / Mac OS X - High Sierra - RenderTexture::clear

« on: November 13, 2017, 03:58:50 pm »

Hey guys! I have some troubles with clearing render textures (or may be RenderWindow). And made some investigations. Here's the code:

#include "include/SFML/Graphics.hpp"

int main() {
        sf::RenderWindow app(sf::VideoMode(400,400), "test");
        sf::RectangleShape a(sf::Vector2f(10,10)), b(sf::Vector2f(1,1));

        sf::RenderTexture tex;
        sf::Sprite spr;

        tex.create(400,400);
        tex.setActive();
        tex.clear(sf::Color(0,0,0,0));
        int pos = 10;
        spr.setTexture(tex.getTexture());

        while (app.isOpen()) {
                sf::Event event;
                while (app.pollEvent(event)) {
                        if (event.type == sf::Event::Closed)
                                app.close();
                }

                pos += 1;
                a.setPosition(sf::Vector2f(pos, 10));

                app.clear();

                // Uncomment this to fix
                //app.draw(b);

                tex.draw(a);
                tex.display();
                app.draw(spr);

                tex.clear();
                app.display();
        }
}

 

If there's no draw calls on RenderWindow except the one with drawing RenderTexture it leads to some artifacts.
I attached the image from my game and from the example. As you can see - there's kinda trail, but it is not the same as without "clear" call.

And there were no such issues before High Sierra update.

just use different Rectangle for collision check

Graphics / Re: Shape is disappearing when i try to move it

« on: November 12, 2017, 09:04:30 pm »

you use move wrong way, so use setPosition instead.
move(arg) = setPosition(getPosition() + arg)
