Top 23 C++ Game Engine Projects

  • GitHub repo Godot

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

    Project mention: help I can't find out why these errors keep happening, it always happens whenever I try to change a scene, and its most likely a problem in the shaders from what I gathered the only few shaders that I have are god rays, player damage, and a teleport node (i use as a screen transition) | reddit.com/r/godot | 2021-12-01

    It looks like someone had a similar one-off error here, but weren't able to reproduce it. This might be of interest to the dev team if yours is reproducible. Can you make a minimum working example, or upload your entire project file somewhere?

  • GitHub repo Cocos2d

    Cocos2d-x is a suite of open-source, cross-platform, game-development tools used by millions of developers all over the world.

    Project mention: Im learning C++ and want to make a small game with it. What do you suggest me for graphics? | reddit.com/r/gamedev | 2021-11-20
  • Scout APM

    Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

  • GitHub repo pyxel

    A retro game engine for Python

    Project mention: Creative coding with Replit | dev.to | 2021-11-24

    Pyxel is specialised for making retro-type games, inspired by console games from the 80s and early 90s. You can only display 16 colors, and no more than 4 sound samples can be played at once, just like on the earlier Nintendo, Sega, and other classic games systems. If you're into pixel art, this is the game engine for you.

  • GitHub repo Minetest

    Minetest is an open source voxel game engine with easy modding and game creation

    Project mention: Help building Minetest on Linux Mint | reddit.com/r/Minetest | 2021-12-01

    git clone https://github.com/minetest/minetest.git

  • GitHub repo entt

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

    Project mention: I wrote a simple Go->C++ compiler to use for gameplay programming. Here's a demo of its use for my game project (along with an editor tool). I show the generated C++ in the end of the video. Compiler source code is ~1500 lines, link in video description. Will do a deeper public release soon! | reddit.com/r/golang | 2021-11-25

    Interop: With this compiler I have direct interop to existing C++ libraries and codebases. For example I use EnTT for the entity-component data storage in the game demo here, and I'm able to call to the C++ including Go's generic syntax translating to template calls. That's not as easy with Cgo (and also Cgo adds huge overhead)

  • GitHub repo urho3d

    Cross-platform 2D and 3D game engine

    Project mention: achieving 00's / ps2 graphics | reddit.com/r/gamedev | 2021-09-25
  • GitHub repo o3de

    Project mention: So how exactly do I learn programming as a whole?? | reddit.com/r/gamedev | 2021-11-05

    If you're still set on Unity, now's the time to open it back up again. If you've decided Unity is too much for right now, here's a much simpler web-based alternative for you: GDevelop. It uses visual scripting (no/low code), works in a browser (or offline if you like), and has some built-in guided tutorials.

    Project mention: Are there any Python gamedev frameworks with complete beginner tutorials? (for a usual Godot dev) | reddit.com/r/gamedev | 2021-11-27

    It's probably overkill for what you need, but Panda3D is a game engine originally started by Disney that has pretty extensive documentation: https://www.panda3d.org/

And a difference of 1500 contributors on Godot, versus 37 total contributors on Defold.

  • GitHub repo xray-16

    Improved version of the X-Ray Engine, the game engine used in the world-famous S.T.A.L.K.E.R. game series by GSC Game World. Join OpenXRay! ;)

    Project mention: If software (OpenXRay-engine in this case) has a BSD-style license, does that automatically mean I can make derivative works (eg a new game, unrelated to S.T.A.L.K.E.R.) and sell them? | reddit.com/r/foss | 2021-11-28
  • GitHub repo Amazon Lumberyard

    Amazon Lumberyard is a free AAA game engine deeply integrated with AWS and Twitch – with full source.

    Project mention: AGS developer confirms this is a different glitch from beta. | reddit.com/r/newworldgame | 2021-11-02

    Actually, we do. It's on Github. Not a leak. Open sourced by Amazon: https://github.com/aws/Lumberyard

  • GitHub repo Gosu

    2D game development library for Ruby and C++

    Project mention: My solo-developed, Ruby powered, platformer game Super Bombinhas will be available soon on Steam! | reddit.com/r/ruby | 2021-11-18

    By the way, it's worth mentioning that there's a .deb for Debian-based distros that you can get for free on https://victords.itch.io/super-bombinhas. Also, if you're willing to do a bit more work, you should also be able to run it on Mac - you'd just have to install Ruby and the Gosu and MiniGL gems, then clone the game's repo and follow the Readme.
