Fixes #170. This is work in progress PR for adding SoundRecorder functionality to rust-sfml. I also created an example on how the the functionality could be used. I welcome any suggestions on how to improve the API. I still need to add documentation and work a bit more on the unsafe functions. Now the compiler is optimizing the closures during monomorphisation so much that I don't even need the void* because the function call gets inlined directly. But syntactically I still need an instance of the type of the closure to call it (I think). If there is a way to call a closure just by knowing it's type please let me know 😃.

Having issues with rendering on the windows 7 platform. The example provided which is supposed to draw a red cricle on a greenish-blue background just draws a black screen. Changing the colours used result in the same black screen. Although drawing the shape when a colour has not been assigned results in a white circle with a black background.

I have tried rsfml on two windows 7 machines, same result. I have also tried rsfml in Ubuntu (same machine), no problems and works as intended. I have tried the c++-sfml build on windows 7 (same machine), no problems and works as intended.

Not sure where this issues is coming from, thanks.

Got the following message in debug mode after creating the music with helper function, which has a shorter scope for its Vec/Cursor, and trying to play it afterwards. error: process didn't exit successfully: target\debug\sfml_test.exe (exit code: 0xc0000005, STATUS_ACCESS_VIOLATION). Supposedly, it's CSFML/SFML fault for no indication of pointer's lifetime in documentation or elsewhere. Though I don't have a clear solution. At least impl Into<Box<[u8]>> with pinning should suffice for from_memory.

I'm having trouble linking rust-sfml on Linux. I'm using the same ppa as rust-sfml is using for Travis, but when it reaches the linking stage, a bunch of undefined reference errors are thrown: https://travis-ci.org/dguenther/rustchip/builds/14399546

I've had the same trouble on my local build server. Does anyone have any ideas how to debug this?

Borrow pointer seems to be too restrictive, I've made a branch with a replacement using Rc< Refcell< Resource>> to handle SFML resource.

Someone had Review on this?

@darnuria? @krzat? @KarlZylinski you seems to have problems with borrow pointers, is Rc a good replacement?

Tryed to compile some samples on windows 10 x64 with the new 0.16.0 and got the following stack trace:

This happens on both msvc and gnu toolchains.

Here are two pictures, with a pair of modified Pong examples with a ball radius of 30. and antialiasing levels 0 and 8 respectively.

I have a low-res monitor, but I think the difference is clearly visible.

  • [ ] Color
  • [ ] ConvexShape
  • [ ] Font
  • [ ] FontInfo
  • [ ] Glyph
  • [ ] RectangleShape
  • [ ] RenderTexture
  • [ ] RenderWindow
  • [ ] Shape
  • [ ] Text/TextStyle
  • [ ] VertexArray
• Window (need to evaluate if we can support touch / mobile device)
  • [ ] events
  • [ ] Joystick
  • [ ] Mouse
  • [ ] Sensor
  • [ ] Touch
  • [ ] Window

  • [ ] Listener
  • [ ] SoundBuffer

When building on Windows rust-sfml wasn't able to find my CSFML and SFML libraries. Found out that the paths in the build scripts were using forward slashes, not back slashes. Updated them, and also had them look for SFML libraries at SFML_HOME, not just CSFML libraries at CSFML_HOME.

This addresses #138 (I think). I bumped the versions; can change back if you want.

I'm not sure if other object behave in this manor, but for something as simple as a shape constructor, is returning Option the best option (no pun intended)? As far as I can tell, the only reason None would be returned would be due to an allocation error, and that would imply the program is out of memory. If that's the case, then there are a lot bigger problems at hand that shouldn't be dealt with wherever a shape is getting created. I feel a fail!() if the shape is null when created would make more sense, but that's just my opinion.

I have just installed the library and fixed some issues linking SFML and CSFML. When running the program, I get this error:

This is my code:

extern crate sfml;

use sfml::graphics::*;
use sfml::window::*;

fn main() {
    let mut window = RenderWindow::new((800, 600), "Hello", style::CLOSE, &Default::default());

    loop {
        while let Some(ev) = window.poll_event() {
            match ev {
                Event::Closed => return,
                _ => {}
            }
        }

        window.clear();
        

        window.display();
    }
}

I installed SFML and CSFML via brew.

Thank you

I have both a dev environment in Ubuntu and Windows10, I am trying to cross-compile a binary for windows. When I set SFML_STATIC I get this error:

error: could not find native static library `sfml-system-s`, perhaps an -L flag is missing?

I have both tried using the information in the Wiki (both installing via pacman and manually). I can see that the sfml-system-s.a and sfml-system-s-d.a` both exist in the libs folder.

I'm not really sure how to coax the build to complete so that I don't have have SFML DLLS installed in order for my program to run

There is a warning about this on sfml documentation

When using this with rust, the font does not work if the buffer is dropped. This should be in the documentation.

Dear rust-sfml maintainers, hi @jeremyletang,

Thanks for rust-SFML: I am very happy I can use one of my favorite graphics libraries on Rust :-)

One of the cool things of Rust is that one can add examples to the documentation, as already done, for example, for the Window struct.

However, for simpler types, the documentation feels incomplete.

For me, a rustling, I would enjoy seeing more examples in the documentation rust-sfml. I even volunteer to do so (sure, we'll probably schedule a quick chat, I will use Pull Requests, etc). The CONTRIBUTING.md could be more helpful in telling me when a PR is likely to be accepted and when not :-)

How do we proceed from here?

It would be nice to have a more casual way for users to ask questions.

Pinging repo owner @jeremyletang. I would be grateful if you enabled that feature in the repository settings! Thank you very much in advance!

So far most of the effort has been to make the library safe to use in a single-threaded context, but there haven't been much investigation on how it behaves when multiple threads are involved.

At least on X11, it can trigger all kinds of errors to call them from a different thread. And someone messaged me that it can cause segfaults for them to do so.
