Graphics / Re: [SOLVED] MacOS Build and Windows Build has a Difference when Drawing Rectangle

« Last post by Hapax on Today at 10:30:26 pm »

In addition - and something I was going to mention in my previous post but forgot - you should consider DPI awareness.

This can throw all sorts of things out if one version is DPI aware (even if automatic) and the other is not.

It's a very complicated issue, by the way, but I think Mac and Windows treat it differently by default. Possibly the way SFML treats it is different in those operating systems too but I'm not sure.

Graphics / How to correctly draw a triangle fan?

« Last post by Nortski on Today at 07:49:40 pm »

So so close to getting my visibility polygon working. I'm using an SFML triangle fan with all the vertex points sorted by angle size with position 0 set to the mouse coords and the last element set to element 2, I needed to do this to fill in the gap for the last triangle.
However; a triangle appears to be missing at certain locations, see video.
I suspect that I'm having an out by one issue with my loop. I've tried rearranging a few numbers but this is the closest I can get.
https://streamable.com/d46yih

sf::VertexArray visibilityPolygon(sf::TriangleFan, vectorAngleContainer.size() + 1);
visibilityPolygon[0] = ray[0].position;

for (int i = 1; i <= vectorAngleContainer.size(); i++)
{
    visibilityPolygon[i] = sf::Vertex(sf::Vector2f(vectorAngleContainer[i-1].position.x, vectorAngleContainer[i-1].position.y), sf::Color::Red);
}
visibilityPolygon[vectorAngleContainer.size()] = visibilityPolygon[1].position;

vectorAngleContainer() is a vector of structs that holds a point and and angle.

General / Re: Can you integrate allegro into an sfml window?

What sort of video do you need to support? If it's just for some intro videos/cutscenes pl_mpeg is pretty easy to integrate with a RenderTexture/AudioStream

This sounds like what I need. Could you please show me an example script of the video player being used for sfml?

The solution is to also compile the SFML dependancies using the

The dependancies come pre compiled , hence no support for UCRT.

If you don't need audio, OpenCV is very easy to get working in SFML (1 line of code to load a video, about 5 lines to read a frame into a texture, do that with a timer). I haven't done much with it, I was just testing security camera footage analysis and playback, so the video was already low framerate.

or there's more comprehensive support with libvlc:

I see... I thought perhaps allegro would be reasonably easy to put into an sfml window. Looks like that brings me back to sfemovie, which is something I have so far unsuccessfully setup.    Thanks anyways.

This is a known bug which was fixed in SFML 2.6

General discussions / Music does not rewind.

« Last post by mejak on May 14, 2024, 06:57:23 pm »

I'm using 2.5.1, and I noticed that when music streamed from a .flac file stops from playing to the end, it doesn't rewind, so the next time you play it, it immediately stops. I fixed it by calling stop() right before play().
If it's a known bug, or if it was fixed, or if I'm missing something, you can delete the thread, since I'm ok with my hacky fix, just thought you'd know.
