  • [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.

  • LibOS – 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.

    Even fallowing you can't build with the instructions provided most because you will need some things of android ndk to properly build the allegro. Also, this build instructions is for build for build allegro for use in an Android apk.

    I am trying to find the latest version of allegro + DJGPP that I can use to build a game. I found the 4.2 branch of allegro, but I am unsure which version of DJGPP to use to build it.
  • GeForce NOW leak includes Cities Skylines 2 in its list of unreleased games.
    Factorio was written in C++ with help of Allegro graphic library, it's custom game engine, models are made in Blender, rendered in a 45deg angle to match isometric view. Unity wouldn't handle a game with that scale - it has too many "useless" features for that type of games.

  • Factorio Violated Our License | 2021-08-02
    I'm an Allegro 5 ( developer. We have a very simple license that simply requires putting the license in your distribution. Factorio has never complied with this.
  • I ported Allegro 5 to python | 2021-05-02
    Allegro 5 already comes with Python bindings if you someone wants to use it and write in Python: | 2021-05-02
    Allegro 5Β is originally a game development library in C language. Since I found this library to be ideally powerful and I developed dozens of games with it in C, I found it nice that I could also use it in python in case of mini projects which require less performance (given the slowness of python compared to C). In short, you can install it with:
  • New to c++, need help to try to understand this piece of code from Allegro library
  • Allegro 5.2.7 Released | 2021-03-09
