  A retro game engine for Python

  Project mention: Engine for 10-year-old who also wants to learn how to write code (ie. not block programming) | reddit.com/r/gamedev | 2021-02-12

  Not a game dev, but I remember looking at a tiny game engine called pyxel that seems to fit your description very well.

• Minetest

  Project mention: Is there any future to Multithreaded Minetest? | reddit.com/r/Minetest | 2021-02-24

  Gaming meets modern C++ - a fast and reliable entity component system (ECS) and much more

  Project mention: I need help understanding ECS. | reddit.com/r/gamedev | 2021-02-21

  You should probably look at something like Entt. It's C++, though. I assume you use C based from your sample code.

• urho3d

  4 3,474 9.1 C++

  Cross-platform 2D and 3D game engine.

  Project mention: What are the best C++ frameworks for desktop applications? | reddit.com/r/cpp_questions | 2021-02-10

  wxWidgets/Qt for desktop, SFML for 2D games. Haven't seen recommendations for 3D except things like Godot. But https://urho3d.github.io/ looks fancy.

• magnum

  1 3,364 9.6 C++

  Lightweight and modular C++11 graphics middleware for games and data visualization

  Project mention: Best Vulkan wrapper / low-level graphics library? | reddit.com/r/GraphicsProgramming | 2021-02-09

  (Sorry for a self-promo, hope that's fine.) If you don't mind being an early adopter and use something that's still undergoing heavy development and is not complete yet, I'm building a low-level Vulkan wrapper in Magnum. If you aren't familiar with Magnum yet, it's a C++11 library that has (among other things) a thin OpenGL/GLES/WebGL wrapper that removes the platform-specific extension hell and most of the boilerplate while still allowing you to work with the raw APIs if you need ... and the same is now being done for Vulkan.

  Project mention: Game engine for a 2D, top down, rogue like, pixel art game? | reddit.com/r/gamedev | 2021-02-16

  Or if you'd rather do a bit less coding, Construct 3 or GDevelop? Both of those are decent 2D engines with visual scripting. You can also try out both of them in the browser, so you can decide if you like them without having to download anything. (There are full local versions too, it's just convenient to be able to test something really quickly in a browser to see if you like it).

I currently LERP between position keys, and SLERP between orientation(quaternion) keys. Should I also just use LERP for scaling? I remember reading somewhere to use a log function. | reddit.com/r/GraphicsProgramming | 2020-12-31

  Animation compression is a science in itself. https://github.com/nfrechette/acl is a pretty serious project for that.
