On the surface it looks like an OK game but the situation is actually dire internally, with the base engine ("minetest core") featuring immense technical debt like very poor rendering performance (the equivalent of MC's "Use VBO" option was only made available in 2016), nonexistent control over things other than just blocks and entities, no client-side prediction (the game constantly feels janky), nothing in the way of e.g. pathfinding to create mobs that don't hog the CPU, all UI/HUD is completely server-bound and laggy, heck, you can't even implement signs without creating an entity for every character to be displayed on the sign.

Now you can make use of operator| and operator&. Here is the full source. It'll be a bit better when it's ported to C++20 with concepts, as the SFINAE produces the usual ugly error messages with enable_if.

o3de
Open 3D Engine (O3DE) is an Apache 2.0-licensed multi-platform 3D engine that enables developers and content creators to build AAA games, cinema-quality 3D worlds, and high-fidelity simulations without any fees or commercial obligations.
Project mention: O3DE - Sources of information, examples and tutorials | reddit.com/r/O3DE | 2022-11-09 -
Project mention: Good graphics engines to visualize my physics framework? | reddit.com/r/gamedev | 2022-11-14
If you want something that gives you more control you could use magnum.
-
Urho3D, an open source C++ game engine.
-
Scout APM

Project mention: What features would you like to see that are not available in leading game engines | reddit.com/r/gamedev | 2022-07-27
It sounds like you're asking them to just remake https://flaxengine.com. (Minus ECS)
-
NoahGameFrame
A fast, scalable, distributed game server engine/framework for C++, include the actor library, network library, can be used as a real time multiplayer game engine ( MMO RPG/MOBA ), which support C#/Lua script/ Unity3d, Cocos2dx and plan to support Unreal.

Panda3D
Powerful, mature open-source cross-platform game engine for Python and C++, developed by Disney and CMU
Project mention: Why I enjoy using the Nim programming language at Reddit. | reddit.com/r/RedditEng | 2022-11-14I used to be a huge Python fan. After working with Python for many years though, I started to get annoyed with more and more things. For example, I wanted to make games with Python and even contributed to Panda3D, but Python is a very slow language and games need to be fast. Then, when making websites, typos in rarely run and tested code like exception handlers would crash in production. Python also does not help with large refactors. Every function is ok with taking anything so the only way to find out if code does not work is to run the code and write more tests. This got old fast.

Project mention: Devs not baking monetisation into the creative process are “fucking idiots”, says Unity’s John Riccitiello | reddit.com/r/pcgaming | 2022-07-14
Torque3D (the engine used to make Tribes 2, now open-source)

Spring RTS game engine
A powerful free cross-platform RTS game engine. - Report issues at https://springrts.com/mantis/ (by spring)
Project mention: Total Annihilation (Currently marked unsupported) works great on the deck! Just had to manually set the resolution. | reddit.com/r/SteamDeck | 2022-11-18That said, SpringRTS is a thing if you've not seen it before.
-
Atomic Game Engine
The Atomic Game Engine is a multi-platform 2D and 3D engine with a consistent API in C++, C#, JavaScript, and TypeScript
-
JoltPhysics
A multi core friendly rigid body physics and collision detection library, written in C++, suitable for games and VR applications.
Project mention: Two new NVIDIA Vulkan extensions to accelerate RTX IO are supported on both Linux and Windows | reddit.com/r/linux_gaming | 2022-11-16It is a very wide standard, yes. But the most issue is that it uses discrete collision detection which has pretty common limitations. So if you are looking for an alternative, try Jolt instead. It's open-source, MIT licensed, used by a AAA game and uses continuois collision detection.

defold
Defold is a completely free to use game engine for development of desktop, mobile and web games.
looks very neat, but it doesn't really get more OO than JavaFX, does it ? would you call this code functional & idiomatic in any relevant sense of the term? https://github.com/defold/defold/blob/dev/editor/src/clj/edi...
