Top 23 C++ Game Engine Projects

  • GitHub repo Godot

    Godot Engine – Multi-platform 2D and 3D game engine

  • GitHub repo Cocos2d

    Project mention: Still have nothing to do with VS Code - WHAT SHOULD I DO WITH IT IN TERMS OF MAKING THINGS THAT ARE RELEVANT TO MAKING AN RPG MAKER MV GAME, NOT JUST EDITING NORMAL TEXT!? + DOES USING VS CODE WITH BASIC THINGS IN GITHUB WORTH IT? | reddit.com/r/RPGMaker | 2021-09-23

    Speaking about markdown files on GitHub, I know that there are some repositories that have very stunning README markdown files, such as this one for Cocos2d-x, whcih includes images in conjunction with text. I might do the same for my repository as well. Considering VS Code have an extension for .md files, this might come in handy when I consider using VS Code to contribute to my game projects.

  • Nanos

    Run Linux Software Faster and Safer than Linux with Unikernels.

  • GitHub repo pyxel

    A retro game engine for Python

    Project mention: Is python a good programming language for game development? | reddit.com/r/learnpython | 2021-10-14

    Longer answer: it depends. There are specialty frameworks in python that are really good for messing around with games. For instance the existence of pyxel is delightful. But is it going to be a track to releasing an indie game that can get you paid? Probably not. But if you can think of a game that you want to execute in python or using particular python libraries then absolutely do so if you're productive in python.

  • GitHub repo Minetest

    Not really, I was referring to the num_emerge_threads option.

  • GitHub repo entt

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

    Project mention: Upcoming ECS in UE5 (Mass) | reddit.com/r/unrealengine | 2021-10-03

    Excellent! I've been using ENTT for a UE-compatible C++ ECS library for a while but it'll be good to get something in-engine, and it opens a lot of possibilities for speeding up other parts of the engine too.

    Project mention: Is There A Port Of The Original Stalker Games? | reddit.com/r/SwitchPirates | 2021-08-11

    This is, perhaps, not that far-fetched. There is, in fact, an open-source engine replacement that runs on linux and has been compiled for ARM64. Essentially the STALKER equivalent of Xash3D.
