Title: Deprecated setParameter (sf::Shader) equivalent
Post by: korczurekk on October 18, 2016, 08:39:18 pm

Hi,
I've updated my SFML to 2.4 and realised that sf::Shader::setParameter is deprecated. I tried to remove it from my code:

transform.rotate(36.f * deltaTime.asSeconds(), {0.f, 0.f});
shader.setParameter("matrix", transform);
 

And wrote that:

transform.rotate(36.f * deltaTime.asSeconds(), {0.f, 0.f});
shader.setUniform("matrix", transform.getMatrix());
 

But nothing is being drawn. I mean, background is cleared normally, but transformed vertices are… somewhere.

What can be the problem?

Should be

shader.setUniform("matrix", sf::Glsl::Mat4(transform));

However your code calls an overload of setUniform with a const float* argument, and I can't find which one is chosen -- but most likely the wrong one if it doesn't work like before. This could be an issue of the new API.

Thanks, it works well now. :)
