  • [Handmade Network] How to write better (game) libraries
    Even if someone wants to use VS2008 for game development, it only took me a Google search to find which doesn't have any dependencies and a very permissive licence.
  • how do i include glfw in my code to make a window? | 2021-08-31
  • LibOS โ€“ Cross-platform OS features in C++ | 2021-08-23
    You seem to have had a similar impetus as I had 20 years ago when I created GLFW (though with a slightly different focus).
  • Is there a way to get japanese text input in raylib? | 2021-08-23
    Thanks for the detailed explanation. I'm afraid I didn't considered that use case for raylib and it would require some investigation to implement it... but raylib uses internally GLFW for desktop platforms and I've seen there is a related issue: About IME support by the browser, it should be investigated. Feel free to open an issue on raylib GitHub for further investigation!
  • Massive trouble with GLFW header inclusion. Can someone help?
    Looking at the actual code of the .h file, it looks pretty empty, and like it needs some extra files perhaps. For instance, functions are just filled with comments with some random explanations, so they are basically 1 line, which probably does nothing. Here you can take a look yourself on github.
  • Hey, I want start
    I would suggest using GLFW and Glad with C++ and use LearnOpenGL as a refrence
  • Compiling in MacOS M1 Chip (arm64) | 2021-07-22
    Now I read the logs and it seems the issue is with GLFW. I've found this:
  • Opengl(glfw) gears on termux x11 NO ROOT!! | 2021-07-19
    Clone the glfw repositiory - git clone
  • 3D Visualization with C++
    Use to get a window with an OpenGL context.
  • A better way of running Minecraft Without XWayland. Because I REALLY had nothing better to do with my life. (which is where I got some patches from) says there wasn't much upstream interest on merging the patches. But (the fix for the freezing issue) might be a good candidate for merging, though I don't know how GLFW people work, so I cannot comment on if it is properly upstreamable or not.

  • What would you say is a good GUI library for a beginner (someone who's never dabbled in GUI programming before, but has several years of experience with C++)?
  • Creating first C++ program for beginner
    If you want to make a gui program using C++, you could try using DearIMGUI.
  • Eli5 How are video game main menu/settings screen/inventory screens programmed?
    There are many options but I believe the most popular paradigm is to use immediate mode UIs, like Dear ImGui, and hook them into the rendering engine itself (i.e. translating the UI draw calls to DirectX / Vulkan), with custom textures/fonts/etc. to make the UI feel 'native' to the game.

  • GUI lib learning material? | 2021-10-14
    E.g., ImGUI (amongst others), source is on git.
  • I can't make up my mind what C++ GUI framework to use. It needs to be very fast in updating the constant data stream I am displaying. | 2021-10-12
    Have you looked at ImGui?
  • Is it worth to learn C instead of C++ in 2021 / 2022
    As for GUI frameworks, ImGui is worth checking out, but that's C++ as well.
  • Working on some UI to make debugging my Game Boy emulator a bit easier | 2021-10-10
    The look is mostly thanks to the UI library, but thanks! I'm using Dear ImGui with SDL2.
  • Making a game with a mouse-based interface : engine/library suggestions | 2021-10-02
    I've been enjoying working with Dear ImGui recently. It might not be exactly what you're looking for but it does all the things you want and it's really simple to use.
